tennis ball bounce on different surfaces experiment

Each ball in a can is different in weight, diameter, and bounce. 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. 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. An alternative method would be the measuring person holding a video camera level with the approximate height that the ball reaches after bouncing and videoing the ball reach the top of its arc. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. A glass ball will bounce higher than a rubber ball if it doesnt break. the initial bounce height is 1 m). The impact duration was between 65 and 71 ms. 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. As energy cannot be created or destroyed it follows that the energy must have come from the energy that the ball possesses. an incorrect and unreliable result. A cold tennis ball bounces lower than a warm one. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. There are more than 160 different types of tennis surfaces. Keep your balls warm in order to get the best bounce possible. As drag is a squared function, proportional to the square of the velocity, it is impossible to calculate the velocity that the ball hits the floor at. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. 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. 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. 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. This therefore provides accurate and reliable results. As a result, the ball is lifted in this manner. An average will then be taken. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. 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. Decide on a height you want to drop the balls from . Our team of volunteer scientists can help. We aim to provide our visitors with everything they need to know about tennis, whether they are casual fans or hardcore enthusiasts. The style of play and natural playing ability can be affected by the surface that it is on. 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. Record the new pressure reading in your data table and repeat steps 4 and 5. or carpet. Now, take your video and watch it to gather your data. Conclusion: The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. found that different surfaces absorb different amounts of energy, and the less This blew the light balls away, giving us an unvalid result or catch. 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. Which surface bounces a ball the highest? Hypothesis. (Doherty, 1991). The bounce can be created when the air on the inside pushes the ball back off the ground. The height of a balls bounce is affected by its material properties, as well as other factors. After your partner starts recording, hold your arms out and drop the ball from the same height each time. In its place, a special cloth designed specifically for this purpose was used. the concrete surface is the hardest surface, it allowed more energy to be released The ball is slowed down by gravity so that it doesnt bounce as many times until it stops. solid. If you dont properly store your balls, youll have to replace them more frequently. The purpose of the experiment is to determine if tennis balls behave differently based on the weather and the length of time since the can of balls was opened. 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). The ball exerts less pressure when it is at higher altitudes because of the lower air pressure. The temperature of a tennis ball can affect its bounce height. This is because the ball starts with more GPE. The more energy absorbed by the surface, the less that remains in the ball for it to bounce. 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. This means for the ball to reach terminal velocity the drag force has to be bigger and for the drag force to be bigger the ball has to fall faster (so that more air particles hit the ball every second). The first independent variable that will be tested. Aim:To find out what affects the height to which a ball bounces. The higher the ball goes, the more GPE it ends up with. The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . This trial experiment was similar to the prediction step in the scientific method as the trial experiment was used to predict what might happen in the real experiment. CR can be found out by looking at a graph, the gradient, as a percentage of 1 gives the amount of energy conserved and therefore CRcan be found without knowing v22or v12. The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. 30% of the energy that the ball hits the floor wit is lost. - Measuring tape x As a result, they move at a slower rate of speed with less energy. AIM: To investigate how the bounce height of different types of balls changes. 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 is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. A lot of Do five drops on your first surface. [accessed August 4, 2006]. To be consistent, again measure to the bottom of the ball. Kinetic energy and ball shape. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use.

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. METHOD: 1. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. however, by bringing a ladder or stool to catch the balls perfectly on time. The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. This would allow one to find the terminal velocity of the ball. When the temperature drops, gas molecules in close proximity. order to give a fair experiment. The bounce should be between 53 and 58 inches. The more particles per cubic meter, the more drag acting upon the ball. Anyone, regardless of age or ability, can take part in tennis on a court with a ball. 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. In this paper, the dynamics of a bouncing ball is described for several common ball types having different bounce characteristics. 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. 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. 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. 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. The grass does not provide as much upward rebound when the ball hits it. carpet, tennis 57 cm 56 cm 61 cm 58 cm The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? were able to construct a successful experiment. This means that if a heavier ball is to be used then it will need to be dropped from higher to reach its terminal velocity. We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. Masses of tennis balls range between 56.0 and 59.4 grams (2011). the higher it popped up into the air. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. Materials 1. Does it slope up or down? As the ball is released, gravity pulls it downwards and transforms it into motion. bounces the highest on smooth concrete. It shows that heights were recorded that exceeded 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. This can be explained by two factors. EQUIPMENT: 1 metre ruler 1 table tennis ball. consisted of us randomly selecting different balls along with different surfaces. The same surface can be used to play both doubles and singles matches. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. When it is dropped, the air molecules will squish together and then spring apart. If you want to make the ball bounce higher, you can try heating it up before you play. It does not store any personal data. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. Concrete4. The weight and material of the ball will be kept the same throughout the experiment by using the same ball. . The reason balls bounce is quite advanced science. faced. This cookie is set by GDPR Cookie Consent plugin. Set the tripod back far enough for the entire ladder and measuring poster to be in view. 3. We then bounced the balls on the surfaces and we were able to work our way around them, giving us a more successful 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. Why does a tennis ball bounce higher on concrete? As the ball hits the floor with less KE than it would have done if it had been dropped in a vacuum it follows that less energy is converted into elastic potential energy and back into KE again. It is a firm rectangular surface with a low net stretched across the centre. 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. External factors, i.e. You can check the weather stats at. These cookies ensure basic functionalities and security features of the website, anonymously. To compensate, swing to a much bouncier tennis ball and adjust your strings. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. - Four surfaces (carpet, rough concrete, dirt and smooth concrete). During the preliminary experiment it was established that time was not an important factor that had to be taken into account when deciding how many different heights to drop the ball from and the interval between those heights. Copyright 2002-2023 Science Buddies. Grades: Preschool and K-2. Gravel got bounced on the least, 1 time . How can you measure the height a ball bounces? As the ball falls to the surface it has kinetic energy. When the ball is pulled toward the ground, gravity slows it down so that it doesn't bounce as many times. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. In our Let the ball bounce until it stops, and then stop recording. Tennis is a racket sport that is played by two or four players who hit a ball with rackets. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. chose balls and surfaces with different hardnesses, textures and compositions in balls and surfaces will ultimately be the best combination for bouncing a ball high. September 28, 2022 by George Jackson. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. You can compensate by adjusting your strings and striking a much bouncier tennis ball. This will be called the average of the middle three repeats. Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . It should be tall enough to hang up behind your ladder, about 5feet tall. The cookie is used to store the user consent for the cookies in the category "Analytics". In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. We What do you think this means about your results? The Physics of Grass, Clay, and Cement. Take your class outside, to an area with a smooth, flat surface. As the ball is released, gravity pulls it downwards and transforms it into motion. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. Therefore the results are valid. It will be vinyl tiling. Please enter a search term in the text box. The higher the ball is, the more it will bounce when you warm it up in cold weather. 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. 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. Try comparing two days with different atmospheric pressure. The children were oblivious to these . The strength of Nadals forehand is what makes him so good on clay. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. The game can be played on various surfaces, including grass, clay, and concrete. Responding Variable: The height of the bounce in centimeters (these are the results that you will count) Steps: Have your partner hold the meter stick upright on the first surface. 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. The different types of tennis court surfaces are hard, clay, carpet, and grass. 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. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. = The distance between the bottom of the ball at the top of its arc after bouncing and the ground. The balls finish up with the same amount of energy and the only energy given out is thermal energy. With this information, we This did not happen in my experiment however. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. Results are presented for a tennis ball, a . The results are shorter rallies and quicker points. The energy that the ball hits the floor with is kinetic energy. Science Buddies Staff. rubber ball would bounce the highest on concrete. The Racquet Sports Industry's website states that, like human fingerprints, no two balls seem to be alike, and each has slightly different bouncing ability. Drop each ball from a distance of 1 meter onto the surface and record how high it bounces in meters (Example: .46 meters). Therefore the heavier the ball is, the faster its terminal velocity. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. This cookie is set by GDPR Cookie Consent plugin.
