If the KE is the same as they hit the ground the energy stored in the ball as elastic potential energy will be the same also. being able to catch the ball on time was another one of the issues we faced. . Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Aim: to find out which surface bounces a ball the highest. Once the drag force equals the gravitational force all forces are equal and acceleration stops. The grass does not provide as much upward rebound when the ball hits it. As the ball is accelerating due to gravity, at 9.81m/s2it is constantly getting faster and therefore the drag force gets bigger and bigger. You will use an air pump, a basketball, and an air pressure gauge to test if changing the air pressure will change the bounciness of the ball. The steel has a lot of bounce power due to its better storage of energy. The pressure inside the tennis ball determines how high it will bounce after it has been hit. Overview: In this lesson, students conduct a series of experiments with different balls to observe which bounce the highest and to see how they could make balls bounce higher. It is a firm rectangular surface with a low net stretched across the centre. This experiment requires a ball that will bounce and a meter stick or other measuring device. small balls sometimes, but we could have improved this by taking many attempts Keep a close eye on the ball, and instruct Phlebas to do the same. the initial bounce height is 1 m). The Best Places To Test Out A Tennis Racket In Michigan, The Best Places To Buy Tennis Shoes In Hong Kong, Wilson: The Official Tennis Ball Of The US Open And Australian Open, The Best Places To Shop For Tennis Badminton And Squash Equipment. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. Overall, our experiment taught us that harder Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. Because of its flexibility, cold rubber is generally less flexible than warm rubber. Let the ball bounce until it stops, and then stop recording. A glass ball will bounce higher than a rubber ball if it doesnt break. = The distance between the bottom of the ball before it is dropped and the ground. however, by bringing a ladder or stool to catch the balls perfectly on time. This is impossible. is well-inflated and made of rubber which would give it more kinetic energy and if different balls are bounced on different surfaces, then a rubber ball, hen a ball hits a surface, all its kinetic energy has to go somewhere. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. bounces the highest on smooth concrete. Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. If you want to make the ball bounce lower, you can try cooling it down by putting it in the fridge or freezer for a few minutes. For the higher heights the distance from h1 to h2 was almost a meter which meant it was difficult to get eye level from h1 to h2 to accurately in a short amount of time. Ball trial 1 trail 2 trial 3 average This would allow one to find the terminal velocity of the ball. use four meter sticks and go right the way up to four meters. 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. Changes in air pressure could have affected results as could changes in temperature however changes in these two factors would have been small; air pressure would not have changed enough to affect the results in the hour period in which the experiment was conducted, and although the rooms temperature may have increased by a degree or two, due to body heat, over the course of the period temperature was not a major factor that affected the height to which the ball bounced and would not have significantly affected the results. From this it can be seen that using the average of the middle three results is more accurate than using the average of all five, as it automatically discounts most anomalies. Measure from the bottom of the ball. A similar length stick, marked in 5-10cm bands of colour. Changes in the area of linoleum floor tile that the ball collided with may have affected the height to which it bounced to thus producing variation between results. order to give a fair experiment.

Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. Because of this, a fully inflated ball may look deflated if the temperature drops quickly. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. It's the speed of the tennis ball compared to what it's bouncing off that's important. The coefficient to restitution can be found out from a graph of, it follows the gradient of the graph change in h. . We then bounced the balls on the surfaces and, measured the heights. Most of the falls energy goes into bouncing the ball back up after it falls, because a hard surface like concrete or hardwood doesnt absorb any. Let's see if physics can explain what happens. discovered that there is a handful of information that would assist my partner and I 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. Now use your data table to plot points on the graph. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. If the elastic potential energy is the same then the same amount of energy is converted back into KE and so the balls leave the floor at the same speed. 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/Phys_p039/physics/balls-bouncing-off-of-surfaces. Masses of tennis balls range between 56.0 and 59.4 grams (2011). For the lowest three points air resistance is approximately equal to zero due to the ball having a low velocity, as it was dropped from a low height, and therefore hits less air particles per second than a ball traveling at a faster speed. Balls bounce in ways that are affected by gravity. As the ball flattening upon impact with the floor is not visible as it happens so quickly it would be almost impossible to measure the size of the ball on impact with the floor. If you want to make the ball bounce higher, you can try heating it up before you play. an incorrect and unreliable result. 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. Each can from the same manufacturer can be different. Why do balls bounce higher on different surfaces? Does it slope up or down? Copyright 2002-2023 Science Buddies. (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. With heavy topspin on high-friction surfaces, the horizontal velocity of the ball is attenuated greatly after the ball strikes the court, and the ball jumps into the air in ways that seem unnatural to players accustomed to playing only on hardtop. As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. These two results were excluded when averages were being calculated and therefore the average variation between results used for calculating the average was even less than 3cm. An increase in h1, assuming g and m stay constant, results in an increase in m g h1 which results in an increase in GPE. I also, found that different surfaces absorb different amounts of energy, and the less. As a result, they move at a slower rate of speed with less energy.

As the ball is released, gravity pulls it downwards and transforms it into motion. This was when the ball was falling in air. The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. This is due to two factors. The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. The more particles per cubic meter, the more drag acting upon the ball. The surface onto which the ball is dropped upon will be kept the same. Although catching small balls was an issue, we solved it by getting our better Although we had all these challenges, As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. This is impossible. This cookie is set by GDPR Cookie Consent plugin. This will be a table tennis ball. Air resistance exists but does not affect the velocity of the ball significantly. Its not just a game for the wealthy; its also a game for everyone. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. If we Try comparing a hot day to a cold day. Write your measurements down. Try your bounce test in different weather conditions. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. These cookies track visitors across websites and collect information to provide customized ads. carpet, tennis 57 cm 56 cm 61 cm 58 cm In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. Try bouncing different kinds of balls to test this question. What was the outcome? It is also necessary to warm a ball, because the energy inside it is released. How can you measure the height a ball bounces? half the results (concrete), we were incorrect about the basketball. Measuring tape 3. 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. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. 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. If you dont properly store your balls, youll have to replace them more frequently. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. - Pencil x Tennis balls are different at sea level and at high altitudes. found that different surfaces absorb different amounts of energy, and the less Grades: Preschool and K-2. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. Carpet2. would bounce the highest on a hard, smooth concrete surface because a rubber ball Here's what our experiment showed: different ground surfaces will absorb more energy than others, which means that that push back they give to the ball won't be as strong. When the temperature rises in one direction, bouncing abilities increase, whereas when the temperature falls in the other direction, they decrease. us. The energy goes into deforming the ball-- from its original round shape to a squashed shape. The temperature of the tennis ball has an impact on its bounce. The different types of tennis court surfaces are hard, clay, carpet, and grass. Push it against the measuring tape, careful to keep it at the same height. ping pong 2 cm 3 cm 2 cm 2 cm, basketball 82 cm 84 cm 80 82 A cold tennis ball bounces lower than a warm one. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. The experiment was conducted as the method (below) states. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. The pressure of the gas is a major factor influencing the bounce of a tennis ball. For any other use, please contact Science Buddies. or carpet. Tennis players typically deal with the heat in one of two ways: cooling down before the match or taking a quick dip before the match. This would allow the actual coefficient to restitution to be calculated. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. When the temperature drops, gas molecules in close proximity. The trip is going to be thoroughly enjoyable. - Sticky tape - 1 roll. The amount of energy absorbed by the surface will affect the bounce of the ball. But what makes a ball bounce? didn't catch the ball on time before it went back down to the ground, we would get In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. This cookie is set by GDPR Cookie Consent plugin. Length of Lesson: 30 - 45 minutes. Repeat the process three times with the same ball and record results. Make a note of which one bounces up higher and how high they bounce! This will mean that I will have to have the interval between the different heights from which the ball is dropped from less than 20cm, probably at 10cm. Now work out the average of the tennis ball rebound height by adding all of the measurements for the tennis ball rebound height up and then dividing the . Our team of volunteer scientists can help. There were some trends observed in our Watch the video of the dropping tennis ball. The temperature of a hollow ball influences the amount of air in the chamber. This therefore provides accurate and reliable results. The energy chain is as follows: Therefore as energy cannot be created or destroyed the energy the ball starts with must be directly proportional to the energy the ball finishes with, at the top of its bounce, and so if the ball starts with more energy it must therefore finish with more. Does the weather make a difference? It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. Hot balls were the more likely to bounce higher than cold balls. The cookie is used to store the user consent for the cookies in the category "Other. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". solid. 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). Science Buddies Staff. 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. I also Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. We could have improved this If you play in hot weather, your balls may bounce significantly more. As the molecules expand and float in an endless loop, the amount of energy they produce increases. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. My partner and Is experiment which surface bounces a ball the highest? Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. Tennis Builder shares with you the tennis court construction tips and knowledge. Therefore the ball goes higher. As the ball has less KE and is travelling slower it becomes stationary faster at the top of its arc. The height of the ball at each bounce is then calculated. . Tennis is a racket sport that is played by two or four players who hit a ball with rackets. Height will be the variable that we will vary. Do you have specific questions about your science project? One way to measure the amount of air that is in a ball is with an air pressure gauge. Therefore of the GPE that the ball possessed at the beginning some energy is given off as thermal energy. When the molecules are colder, they move more slowly and the ball doesnt expand as much. This is due to an inelasticity in the energy lost when the ball collides with the ground, as well as the fact that the ball bounces every time it is hit. The higher the ball goes, the more GPE it ends up with. Also the ball flattening upon impact doesnt have to be taken into account whereas if one was measuring from the top of the ball as it hits the floor to the top of the ball before dropping it or at the top of its arc after bouncing or the middle of the ball as it hits the ground to the middle of the ball before dropping it or the middle of the ball at the top of its bounce then the fact that the ball flattens momentarily on impact with the floor would have to be taken into account. Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. Since A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. What do you think this means about your results? Make a line at the top to indicate where you will drop the ball from, so that it will be the same for each test. The more KE that the ball possessed as it hit the floor, the more that was transferred into elastic potential energy and back into KE. The reason balls bounce is quite advanced science. Do five drops on your first surface. The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. I do not believe that any ball will reach terminal velocity in this experiment seeing as the maximum height that they can be dropped from is 2m and, as the ball is quite smooth, I do not believe that it will have enough time to accelerate to its terminal velocity before it hits the floor. The more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. [accessed August 4, 2006]. Use the pencil and ruler to connect the incoming and outgoing trajectories of the marble to the point where the marble bounced off the wood. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. However, it was the basketball Concrete4. Is it a straight line? As the ball falls it hits against air particles. 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. Experiment 2 is for testing the effect of air pressure. This is a result of the It is important to let the ball fall out of your hands, and not to push it down with your hands, wrists, or arms. , v is greater therefore KE is greater by a larger amount). quicker and on time before they dropped back down. Why does Rafael Nadal do so well on the clay? These both support my prediction and show that my prediction was correct. This would provide evidence on how the height from which the ball is dropped from affects the height to which it bounces without air resistance. Then draw a line to connect the dots. B. experiment. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. concur, which was catching the small balls. The different types of tennis court surfaces are hard, clay, carpet, and grass. This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. H is the height of the ball before it is dropped. In air considerations have to be taken into account such as air resistance but even so the rough height to which it will bounce to can be predicted before dropping the ball. Some of the balls energy can be converted into heat. Science Buddies Staff. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. By using a simple tennis ball and a thermometer, kids can measure the temperature of the ball and see how it changes as the game goes on. It will not have enough force to bounce if it is lit. Tennis balls are more likely to bounce on grass. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . The harder the court surface is, the higher the rebounded ball will be. The balls dropped from 75 centimeters will bounce higher than those dropped from 50 centimeters, and the balls in the 50 centimeter trials will bounce higher than those in the 25 centimeter trials. Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. Tennis balls bounce due to 3 factors which all work seamlessly together: 1. - Paper x Therefore the heavier the ball is, the faster its terminal velocity. For a falling object the Coefficient to restitution (CR) is equal to the velocity squared as the object is travelling at as it leaves the floor (v22) divided by the velocity squared as it hits the floor (v12): If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h1 and CR. 2. If the coefficient to restitution = 0.7, a ball dropping from h, in a vacuum would reach the height of 0.7 h, As velocity increases air resistance increases in proportion to the square of the velocity. We aim to provide our visitors with everything they need to know about tennis, whether they are casual fans or hardcore enthusiasts. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. This is called the relative speed. Analytical cookies are used to understand how visitors interact with the website. rubber ball would bounce the highest on concrete. - Measuring tape x You can also try using a hair dryer to heat the ball up. Therefore the results are valid. Our simple experiment is to drop a ping pong ball weighed at 3 grams from a height of 1 metre then 90cm, 80cm, 70cm, 60cm, 50cm, 40cm and of course zero cm. Results are presented for a tennis ball, a . . 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. 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Kinetic energy and ball shape. Do different kinds of balls bounce differently? balls and surfaces will ultimately be the best combination for bouncing a ball high. This was added onto another issue we had to In my science fair experiment, the golf ball overall was the ball that bounced the highest. from the ball, therefore causing it to bounce higher than it normally would on dirt This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. 1 tennis ball 1 golf ball. One way to do this is to put the ball in a bowl of hot water for a few minutes. As in both cases the main form of energy is GPE it follows that the higher the ball is dropped from, the higher the ball will bounce. Therefore the ball dropped from the higher height must give out more thermal energy in order to end up with the same amount of energy as the other ball. The harder the court surface is, the higher the rebounded ball will be. Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. The ball gains energy of motion, known as kinetic energy. The movement of the air causes the ball to bounce back off the . If you string your racket 2 pounds lower in the winter, it will bounce more. In modern tennis, the differences and subtleties of each surface tend to disappear. surface bounces a ball the highest. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. As the ball falls to the surface it has kinetic energy. We As a result, the ball is lifted in this manner. The more energy absorbed by the surface, the less that remains in the ball for it to bounce. 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. Conclusion: An investigation into how they impact play on the court. hypothesis, we predicted that a rubber ball would bounce the highest on rough However the conditions were kept the same for each drop of the ball. The ball did not appear to reach its terminal velocity which also supports my prediction. In this experiment you will use a ball filled with air. old and new tennis balls (different surface textures/ages). rubber ball 39 cm 38 cm 41 cm 39 cm. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Why do marbles bounce so high? In this paper, the dynamics of a bouncing ball is described for several common ball types having different bounce characteristics. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. Increased energy and movement results in a bounce. Therefore any change to the height from which the ball starts with affects the height to which it bounces to. To determine how high a tennis ball will bounce when dropped from a . Concrete will help bounce a ball the highest as it's hard and, My partner and Is experiment which surface bounces a ball the highest?, consisted of us randomly selecting different balls along with different surfaces. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. will start at 2m and then move down in intervals of 10cm to 10cm. When it is dropped, the air molecules will squish together and then spring apart. Friday - 25/04/14 Therefore the coefficient to restitution = 0.7. In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. The temperature of a tennis ball can affect its bounce height. measured the heights. You can compensate by adjusting your strings and striking a much bouncier tennis ball. As the ball flattening upon impact with the floor is not visible as it happens so quickly it would be almost impossible to measure the size of the ball on impact with the floor. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up. With this information, we. 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.
