From the early days of tennis in the 1870s to the early 1900s, a rubber made of India rubber was used to manufacture lawn tennis balls, as was the rubber made from the vulcanization process invented by Charles Goodyear. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures. This applies to a ball falling in a vacuum. A tennis court is the venue where the sport of tennis is played. Copyright 2002-2023 Science Buddies. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. The pressure on the ball is created by the air pushing against it. from the ball, therefore causing it to bounce higher than it normally would on dirt High bounce ball 2. Place one of the tennis balls in the freezer for 20 mins 2. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. Do you have specific questions about your science project? Experiment 2 is for testing the effect of air pressure. The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. rubber ball 39 cm 38 cm 41 cm 39 cm. The children were oblivious to these . Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. For the most part, the document is a case study in compulsive precision. Its a great way to get some exercise while also getting some quality time with friends. This would allow one to find the terminal velocity of the ball. [accessed August 4, 2006]. Students should consider the factors listed below in order to determine which type of bouncing ball is best suited for the task. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. were able to construct a successful experiment. Some of the kinetic energy of the ball is lost during the collision with the floor and the ball will not return to the original height. The ball shoots up with less energy because of this. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. carpet, tennis 57 cm 56 cm 61 cm 58 cm Why do balls bounce higher on different surfaces? A lot of Balls bounce in ways that are affected by gravity. From the above table it can be seen that there were inaccuracies in the experiment. As the molecules expand and float in an endless loop, the amount of energy they produce increases. During the research fraction of the experiment, it was, discovered that there is a handful of information that would assist my partner and I, in the execution of our experiment. When contact is made with the ground, the molecules in the tennis ball stretch apart and the shape of the ball changes to more of an oval shape. This will be called the average of the middle three repeats. The ball weighs exactly 2.5g. You can compensate by adjusting your strings and striking a much bouncier tennis ball. . For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. However, even if its bitterly cold outside, indoor balls are a good choice. is well-inflated and made of rubber which would give it more kinetic energy and rubber ball would bounce the highest on concrete. Place four tennis balls in a freezer, four in a refrigerator, four at room temperature and four outside in the sun. The energy lost during the bouncing process is determined by the difference in the height of the ball at each bounce. - tennis ball x C. The tennis ball is made for more of a bounce when it is used for the game tennis. This means that the faster that the ball travels the larger the force of air resistance upon it. Equipment/materials used: A tennis ball is a small, spherical object that is used in the sport of tennis. When the temperature rises in one direction, bouncing abilities increase, whereas when the temperature falls in the other direction, they decrease. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. Air resistance exists but does not affect the velocity of the ball significantly. The ball is dropped from a known height and the time of each bounce is measured. However, you may visit "Cookie Settings" to provide a controlled consent. chose balls and surfaces with different hardnesses, textures and compositions in The more energy absorbed by the surface, the less that remains in the ball for it to bounce. This is why you should have seen that when you bounced the basketball on a relatively hard surface it bounced higher (it lost less energy) compared with when it was bounced on a softer surface . Balls bounce up to 5 . Please enter a search term in the text box. The effect of surface on the bounce height of a tennis ball. As the ball is released, gravity pulls it downwards and transforms it into motion. This is because it is the easiest and quickest variable to alter. Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. Decide on a height you want to drop the balls from . Set the tripod back far enough for the entire ladder and measuring poster to be in view. According to the USTA regulations ball is tested for bounce by dropping it from a height of 100 inches (2.54 m) onto ; a bounce between 53 and 58 inches (1.3462 - 1.4732 m) is acceptable. Answer (1 of 2): Some surfaces absorb more energy than others do. In my science fair experiment, the golf ball overall was the ball that bounced the highest. What do you think this means about your results? Balls are not round. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. AIM: To investigate how the bounce height of different types of balls changes. It should be tall enough to hang up behind your ladder, about 5feet tall. However if two results are recorded that do not fit the trend of other results nor are close to results recorded for that height then the experiments accuracy would be brought into doubt. Once the ball hits the ground, its displacement is momentarily zero. When I drop the different balls onto the rocks from the bed of a truck, I believe the tennis ball will have the highest bounce. When the ball hits the floor and stops, that energy has to go somewhere. Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. My partner and Is experiment which surface bounces a ball the highest? will be from the bottom of the ball as it hits the floor to the bottom of the ball at the top of its arc after bouncing. Warm up the ball before it is used to increase its bounce. I plan to collect at least ten results as this will make the conclusion and graph I am able to draw from the experiment more accurate than if I had less results than ten. If the ball bounces up more than .5 meter then, it is more elastic. Balls bounce differently on different axes. Therefore, harder surfaces will ultimately bounce a ball higher. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. The strength of Nadals forehand is what makes him so good on clay. hard ball made of rubber should bounce the highest on a concrete surface, which 1 tennis ball 1 golf ball. The ball gains energy of motion, known as kinetic energy. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. As it did so the downward force was partially balanced out by the upwards force of drag, increasingly so the closer the ball got to its terminal velocity. The steel ball on an unvarnished pine wood floor may not bounce at all, but rather make a dent, and so what the floor is made out of makes quite a lot of difference. Keep releasing pressure and repeating the experiment until the ball no longer bounces. Although we were correct about were able to construct a successful experiment. Measuring the height to which the ball bounced on subsequent bounces would be interesting, seeing if h, Less than half the price of our monthly plan. Click the "Experiment" button to find out! What factors affect the bounce height of a ball? energy a surface absorbs, the more of it will remain for a ball to bounce. stay constant, results in an increase in m g h, stay constant, results in a decrease in m g h, The surface onto which the ball is dropped will affect the height to which the ball bounces because for any two objects that collide, the properties of both determine the percentage of the kinetic energy either possesses approaching the collision that is conserved subsequent to the collision taking place (Coefficient to restitution) discounting the effects of air resistance. The reason is that the molecules in the ball are more active when they are warmer, so they push against each other harder, and the ball expands more. For multiple bounces, it's just like dropping the ball again from a reduced height. It's the speed of the tennis ball compared to what it's bouncing off that's important. half the results (concrete), we were incorrect about the basketball. The cookie is used to store the user consent for the cookies in the category "Other. Copyright 2002-2023 Science Buddies. Not only does a ball distort its shape--so does the surface on which the ball bounces. September 28, 2022 by George Jackson. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. B. the concrete surface is the hardest surface, it allowed more energy to be released METHOD: 1. It was difficult to get down to the exact level of the blue tack seeing as it meant lowering your entire upper body in the short amount of time taken for the ball to hit the floor and rebound again to get your eye level from h, (where the blue tack was stuck, approximately). What was the outcome? Place the tape measurer against the edge of a wall using the bluetack 3. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. The tennis balls bounce in different ways. Friday - 25/04/14 Take a ball and place it on the 150 cm line and drop it. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball would bounce the highest on a hard, smooth concrete surface because a rubber ball is well-inflated and made of rubber which would give it more kinetic energy and less air resistance. As gravity remains the same the amount of work acting on the ball remains the same (apart from slightly more air resistance due to the ball travelling faster and so hitting more air particles per second, but the effect of this is negligible) and the ball travels further before stopping. Grades: Preschool and K-2. Do you have specific questions about your science project? We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce. The maximum height will have to be less than two meters as that is the maximum height that the equipment allows. Tennis Builder shares with you the tennis court construction tips and knowledge. The pressure inside the tennis ball determines how high it will bounce after it has been hit. Taking an average of several results creates a measurement in the middle of the variation created by the experiment, which is the result that is closest to the height that would be recorded for the balls bounce if it were measured in an experiment that was totally accurate. The weight and material of the ball will be kept the same throughout the experiment by using the same ball. Note whether the ball and surface showed more of an elastic or inelastic collision. Therefore the coefficient to restitution = 0.7. Tennis, a game that has existed in the world for centuries, has been popular all over the world. This means that the higher h. will differ from the height that the ball would have reached had it been dropped in a vacuum. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. We did this by bouncing different types of balls This is why it. (Doherty, 1991). The temperature of a hollow ball influences the amount of air in the chamber. old and new tennis balls (different surface textures/ages). All of the factors that could have affected the results that were uncontrollable could have produced variations between results. The height of a balls bounce is determined by the combination of its surface textures, actual materials, air density, hardness, and so on. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. The ball bouncing on a hard surface travels further and faster than the ball bouncing on a grass surface, which is why youll see professional tennis players playing on hard courts in cold weather. it goes back into the ball, giving it more force to pop back up into the air. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. The ultimate answer was that a basketball This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. Therefore the height the ball bounces will be proportional to the height that the ball is dropped from up to a certain point, where the ball begins to show signs of reaching its terminal velocity before it reaches the ground. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. We then bounced the balls on the surfaces and, measured the heights. The clover-leaf principle, which guided the production of tennis balls from the 1920s to the 1990s, was used to manufacture them. (Image by Harold E. "Doc" Edgerton), http://www.exploratorium.edu/sports/ball_bounces/index.html, http://www.exploratorium.edu/baseball/bouncing_balls.html, Playing the Angles: The Physics of Balls Bouncing Off of Surfaces. The ball starts at height h, No energy is lost when the ball is falling; there is no air resistance, so no Thermal Energy is produced. With this information, we. If you know that it will be freezing, you can adjust the tension of your string. You can even play tennis outside in any weather. As the ball has less KE and is travelling slower it becomes stationary faster at the top of its arc. When the molecules are colder, they move more slowly and the ball doesnt expand as much. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. will start at 2m and then move down in intervals of 10cm to 10cm. 30% of the energy that the ball hits the floor wit is lost. External factors, i.e. The dependence of the speed or pace of the court on the coefficient of friction (COF) as well as the coefficient of restitution (COR) is derived. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. The balls finish up with the same amount of energy and the only energy given out is thermal energy. The changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. When dropped on a solid surface, not even a super ball bounces back as high as its initial height, but some balls do bounce a lot better than others. Repeat the process three times with the same ball and record results. Why Does One Tennis Shoe Pull Your Sock Down? The higher the height from which the ball was dropped from, the higher the height to which it bounced. A tennis balls trajectory is determined by its temperature. This experiment would provide me with more results that are relevant to the experiment that I have already conducted. catcher to catch the balls. The experiment was conducted as the method (below) states. : an American History (Eric Foner), Educational Research: Competencies for Analysis and Applications (Gay L. R.; Mills Geoffrey E.; Airasian Peter W.), The Methodology of the Social Sciences (Max Weber), Biological Science (Freeman Scott; Quillin Kim; Allison Lizabeth), Campbell Biology (Jane B. Reece; Lisa A. Urry; Michael L. Cain; Steven A. Wasserman; Peter V. Minorsky), 4-3 Assignment Project Management Strategies. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. Repeat steps 1-6 with the different balls. Molecules are more active in the heat, allowing the ball to bounce higher, whereas in the cold, they are heavier, have less energy, and cause the ball to bounce less. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. The height of the ball at each bounce is then calculated. On the cardboard, mark the starting point, the point where the marble strikes the wood, and a point along the marble's path as it rolls away from the wood. The maximum and minimum results were included when working out the variation between results however, seeing as the maximum and minimum results were produced by the experiment and are therefore part of the variation between results produced by the experiment. Working out the variation in results shows how accurate the experiment was. Not The air in the ball expands and contracts as it is compressed. Is it a straight line? The higher the air pressure the more air particles per cubic meter. Therefore the height that it reaches is less high. Therefore the ball goes higher. Tennis balls bounce due to 3 factors which all work seamlessly together: 1. So whether you're looking to learn more about the sport or just stay up-to-date on the latest news, we've got you covered. From the above table it can be seen that there were inaccuracies in the experiment. This is impossible. In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. This is why it h2will be from the bottom of the ball as it hits the floor to the bottom of the ball at the top of its arc after bouncing. The energy goes into deforming the ball-- from its original round shape to a squashed shape. and tries to catch the balls on time. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. What material makes a ball bounce higher? Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. use four meter sticks and go right the way up to four meters. an incorrect and unreliable result. It is also necessary to warm a ball, because the energy inside it is released. the initial bounce height is 1 m). This is because the higher the starting height of the ball, the higher the ball's potential energy. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. If we composition so it was higher up in the air, with this we were able to catch the balls quicker and on time before they dropped back down. How can you measure the height a ball bounces? The ball showed signs of reaching terminal velocity because the drag force began to approach the force gravity exerts upon the mass of the ball. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. This proves that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. Make a line graph of your data. order to give a fair experiment. This would mean that one could re-examine the height to which it bounced to and find it exactly instead of having to make a split second judgement which is not half as accurate. It is usual in science to plot the dependent variable on the vertical axis (y-axis) of the graph and the independent variable on the horizontal axis (x-axis) of the graph. One way to do this is to put the ball in a bowl of hot water for a few minutes. Kinetic energy and ball shape. Height will be the variable that we will vary. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. the higher it popped up into the air. Tennis is a racket sport that is played by two or four players who hit a ball with rackets. highest on hard, smooth surfaces. However, it was the basketball Because of its flexibility, cold rubber is generally less flexible than warm rubber. The higher the ball goes, the more GPE it ends up with. For any other use, please contact Science Buddies. The grass does not provide as much upward rebound when the ball hits it. Measure from the bottom of the ball. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. Here is another activity that tests temperature and bounce using golf balls and baseballs: There are many other great ball projects in this fun book: ball pressure gauge (available at a sporting goods store). In this experiment you will use a ball filled with air. Hypothesis. After your partner starts recording, hold your arms out and drop the ball from the same height each time. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. Materials 1. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. Belowis the graph of h1against h2. Science Buddies Staff. Does it slope up or down? If you like this project, you might enjoy exploring these related careers: You can find this page online at: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Sports_p007/sports-science/ball-bouncing-dynamics. Why Tennis Balls Bounce. A glass ball will bounce higher than a rubber ball if it doesnt break. I used a Flexible measuring tape to measure what the height was. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. This causes thermal energy to be given off. Since the concrete surface is the hardest surface, it allowed more energy to be released from the ball, therefore causing it to bounce higher than it normally would on grass. Keep your balls warm in order to get the best bounce possible. It does not store any personal data. When the ball was dropped from the higher heights the ball began to show signs of reaching its terminal velocity before it reaches the ground. To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. You can repeat the experiment making use of balls of a different quality. Warmer balls bounce better than cold ones. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. Bouncing is what makes playing with a ball so much fun. There is a chance that you will bounce. on different types of surfaces, then recorded the height of the bounce. The steel has a lot of bounce power due to its better storage of energy. What affects ball bounce? Push it against the measuring tape, careful to keep it at the same height. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. Which ball will bounce higher off a hard surface? Because of this, a fully inflated ball may look deflated if the temperature drops quickly. Carpet2. Reproduction of material from this website without written permission is strictly prohibited. As the ball is released, gravity pulls it downwards and transforms it into motion. Repeat step 5 with all of your other surfaces. Find a clear space to work in. Let the ball bounce until it stops, and then stop recording. However when the ball is dropped from a relatively low height, drag 0. This experiment requires a ball that will bounce and a meter stick or other measuring device. Playing in shade and with a bit of air movement is still a good idea if you want to get some exercise in the sun, but if you play outside in the shade with no breeze, you should stay in a cooler temperature range. Please enter a search term in the text box. This is because as the ball goes faster it passes through a greater volume of air each second. STEP4 - Watch as the smaller ball flies off into the air! Increased energy and movement results in a bounce. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. Different courts are better suited to each players style. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. Also it shows inaccuracies in the experiment as it shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. This means that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. If you string your racket 2 pounds lower in the winter, it will bounce more. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. Therefore, Concrete4. measured the heights. Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). Then draw a line to connect the dots. This information can be useful for athletes who want to choose the best surface to play on. Place the video camera on a level that will be able to clearly record the experiment, whilst a person sits beside the tape measurer 4. We could have improved this The higher the ball is, the more it will bounce when you warm it up in cold weather. When printing this document, you may NOT modify it in any way. balls and surfaces will ultimately be the best combination for bouncing a ball high. Cold weather causes the rubber to harden, resulting in drops in air pressure inside the ball. - Basketball x This was added onto another issue we had to - Ping pong ball x Since The experiment was conducted well however as the utmost efforts were brought into place to avoid parallax error and it was ensured as far as possible that factors that affected how high the ball bounced, excluding the height, were kept constant throughout the experiment. solid. . experiment. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. (2020, January 12). Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. Necessary cookies are absolutely essential for the website to function properly. Record the new pressure reading in your data table and repeat steps 4 and 5. didn't catch the ball on time before it went back down to the ground, we would get One way to measure the amount of air that is in a ball is with an air pressure gauge. For the lower heights the flight time of the ball was extremely short and again it was difficult to move ones head over the distance from h1 to h2 in order to obtain accurate results. This means that KE is the same for both balls when each ball hits the ground. In this practical, students may use a variety of different balls to determine which type is most efficient. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. If you play in hot weather, your balls may bounce significantly more. On a grass tennis court, e y varies from about 0.6 to 0.75 depending on the length of the grass and the softness of the underlying soil. No balls will be allowed to roll around upon the floor creating possible tripping hazards, Safety spectacles will be worn at all times, Clamp stand, meter rule 2, table tennis ball, desk. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape. The tennis balls bounce in different ways. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. It will not bounce to high if it is heavy. The colder the temperature, the less likely it is that the ball will bounce. An investigation into how they impact play on the court. As a result, they move at a slower rate of speed with less energy. The bounce should be between 53 and 58 inches. Aim: to find out which surface bounces a ball the highest.
