tennis ball bounce on different surfaces experiment

The bounce should be between 53 and 58 inches. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. Experiment Click the following buttons to skip to a page. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. 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. Above this point the height all balls will bounce to will not be directly proportional to the height they are dropped from, but the increase in the height they bounce to will increase more slowly in proportion to the height they are dropped from compared to the increase between lower heights before the ball shows signs of approaching its terminal velocity before it hits the ground. 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. This is because it is the easiest and quickest variable to alter. Aim: to find out which surface bounces a ball the highest. In this experiment you will use a ball filled with air. More thermal energy is also produced. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. A cold ball typically has less bounce than a warm ball. less air resistance. Once the ball hits the ground, its displacement is momentarily zero. The variation between results was obtained by taking the minimum result away from the maximum result. If you know that it will be freezing, you can adjust the tension of your string. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. For our wind situation, one of us stood in the direction that the breeze September 28, 2022 by George Jackson. As the height from which the ball was dropped from was increased, the GPE energy that the ball possessed before being dropped also increased. Improvements that could be made to the experiment if future work was to be done: To provide additional relevant evidence I would conduct further work as follows; I would like to conduct the same experiment in a vacuum. 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. Averages are more reliable than using one result as they take into account variation between results. This is impossible. Therefore, our hypothesis was refuted by our final results. Therefore the ball goes higher. These cookies will be stored in your browser only with your consent. As the ball falls to the surface it has kinetic energy. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. 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. EQUIPMENT: 1 metre ruler 1 table tennis ball. 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. The children were oblivious to these . Then when dropping the ball again eye level was kept level with the blue tack. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. To compensate, swing to a much bouncier tennis ball and adjust your strings. Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. 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. 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. 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. "That's The Way The Ball Bounces," The Exploratorium Museum, San Francisco, CA. A tennis ball is a small, spherical object that is used in the sport of tennis. Try bouncing different kinds of balls to test this question. Observe the height of the 1st rebound height of the tennis ball. The results of the experiment were obtained with a method that ensured that every drop was under similar conditions which ensured a fair test. We could have improved this This also proves the accuracy of the experiment. Best hard court players of all time This means that the faster that the ball travels the larger the force of air resistance upon it. You also have the option to opt-out of these cookies. Tennis balls bounce differently in the high altitude and at sea. Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. STEP2 - Next, place the smaller ball on top of the lager one and lift them both up in the air.. STEP3 - Drop em'!. Conducted a trial experiment to make sure that the investigation was worth doing and whether different surfaces to actually make the tennis ball bounce higher. 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. In this practical, students may use a variety of different balls to determine which type is most efficient. The trip is going to be thoroughly enjoyable. Therefore the energy that the ball hits the floor with = mh, The proportion of energy lost when ball hits the floor = The Coefficient to the restitution of the two objects (C, All of the energy that the ball leaves the floor with is converted back into GPE, If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h, can be found out by looking at a graph, the gradient, as a percentage of 1 gives the amount of energy conserved and therefore C. The clamp stand will be clamped down to the desk using a g-clamp to prevent it falling over and causing possible injuries. I will drop the ball 3 It was decided that the first drop would start at 2m off the floor and then move down in intervals of 10cm to 10 cm off the floor. Aim: to find out which surface bounces a ball the highest. (Doherty, 1991). Why do golf balls bounce so high on concrete? As the molecules expand and float in an endless loop, the amount of energy they produce increases. Keep releasing pressure and repeating the experiment until the ball no longer bounces. All rights reserved. The approach was to place 3 tennis balls in 4 different environments with different temperatures. Once the drag force equals the gravitational force all forces are equal and acceleration stops. The drag force increases as the ball goes faster. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. This cookie is set by GDPR Cookie Consent plugin. . . You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. Our team of volunteer scientists can help. Also the difference between the force of air resistance acting upon a ball travelling at 1ms, and the force of air resistance acting upon a ball travelling at 2ms, is far smaller than the difference between the force of air resistance acting upon a ball travelling at 20ms, and the force of air resistance acting upon a ball travelling at 21ms, , the faster the velocity that the ball reaches. My partner and Is experiment which surface bounces a ball the highest? - Basketball x Grades: Preschool and K-2. However when the ball is dropped from a relatively low height, drag 0. Materials 1. 1 tennis ball 1 golf ball. The changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. 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. Temperature will not affect the balls bounce either as the experiment will be conducted at room temperature, thus not allowing the floor to get cold and in doing so alter its affect upon the ball on impact. The aim of the experiment my partner and I performed was to find out which Does height make a difference? Most of the points on grass are very short. 70% is retained. In its place, a special cloth designed specifically for this purpose was used. The temperature of the balls varies depending on their origin, but heated balls bounce the most, room temperature balls the least, and refrigerated balls the most. Concrete4. Carefully climb the ladder with the ball. This website uses cookies to improve your experience while you navigate through the website. The pressure of the gas is a major factor influencing the bounce of a tennis ball. This is because the ball starts with more GPE. The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. Note whether the ball and surface showed more of an elastic or inelastic collision. Therefore, harder surfaces will ultimately bounce a ball higher. 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. Focus. What do you think this means about your results? These inaccuracies could have been caused by external factors or parallax error even though efforts were made to avoid parallax error occurring - by dropping the ball one time that was not measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. chose balls and surfaces with different hardnesses, textures and compositions in 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 h. Do a larger amount of results; 1cm, 2cm, 3cm, 4cm etc. Keep a close eye on the ball, and instruct Phlebas to do the same. Balls change shape during play. The effect of surface on the bounce height of a tennis ball. 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. Hard court tennis demands a lot from your joints! As for catching the balls on time, we changed our hand positioning and 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. Doherty, P., 1991. High bounce ball 2. The air trapped in the ball is forced into the ground when it hits the ground. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game. Write each measurement in the data table. Tiles3. With this information, we. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. But how does concrete . Why Tennis Balls 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. Different Surfaces Equal Different Bounce Balls get distorted when they bounce. When the temperature drops, gas molecules in close proximity. 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 experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. The reliability of our experiment wasn't so strong. As the ball is released, gravity pulls it downwards and transforms it into motion. 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 . The cookie is used to store the user consent for the cookies in the category "Analytics". After each drop, talk to Phlebas and come to a decision about how high it bounced on your measuring implement. Use a uniform surface to drop the ball onto. It will be vinyl tiling. The Graph on page 23 shows that all of the results were very close together. The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). were able to construct a successful experiment. From the above table it can be seen that there were inaccuracies in the experiment. Why do marbles bounce so high? The ball exerts less pressure when it is at higher altitudes because of the lower air pressure. Science Buddies Staff. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. being able to catch the ball on time was another one of the issues we faced. energy a surface absorbs, the more of it will remain for a ball to bounce. Although we had all these challenges, This causes thermal energy to be given off. Hypothesis If I increase the height from which a ball is dropped then the bounce height will increase because it will increase the speed and create a larger impact causing the ball to bounce higher then dropping it from a lower height. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. 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. As they are pushed about, the molecules in the ball collide with and rub across each other." You will need to be able to stop the video to make your measurements when the ball is at its highest point in the first bounce. The higher the height from which the ball was dropped from, the higher the height to which it bounced. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. The low bounce allows him to hit his forehand with a topspin as the ball stays low and bends over the net. H is the height of the ball before it is dropped. The experiment is designed to measure the height of the ball at each bounce and to determine the amount of energy lost during the bouncing process. "Under Pressure: Ball Bouncing Dynamics.". Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) Reproduction of material from this website without written permission is strictly prohibited. The harder the court surface is, the higher the rebounded ball will be. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. 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. This is called the relative speed. The energy goes into deforming the ball-- from its original round shape to a squashed shape. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball As a result, the balls bounce decreases as pressure decreases. Record the new pressure reading in your data table and repeat steps 4 and 5. it goes back into the ball, giving it more force to pop back up into the air. These inaccuracies could have been caused by external factors or parallax error even though efforts were made to avoid parallax error occurring - by dropping the ball one time that was not measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. The more KE the ball leaves the floor with the longer it takes to stop due to the force of gravity and return back to the floor again. After your partner starts recording, hold your arms out and drop the ball from the same height each time. Then draw a line to connect the dots. didn't catch the ball on time before it went back down to the ground, we would get KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. 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. Cold balls tend to have a bouncier texture. The tennis ball was then dropped from various heights; 1, 1.5 and 2 meters above a hard surface, using a meter ruler, before it was dropped onto the ground and the resulting bounce height measured. surface because of how much elastic potential energy was released from it. What was the outcome? 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. 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. 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. As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. = The distance between the bottom of the ball before it is dropped and the ground. on different types of surfaces, then recorded the height of the bounce. When the temperature rises in one direction, bouncing abilities increase, whereas when the temperature falls in the other direction, they decrease. An average will then be taken. Each ball in a can is different in weight, diameter, and bounce. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. Will the air pressure change the bounciness of a ball? Analytical cookies are used to understand how visitors interact with the website. 2. Take a ball and place it on the 150 cm line and drop it. Therefore the coefficient to restitution = 0.7. It will not bounce to high if it is heavy. This is a result of the Use the pressure gauge to release some of the air pressure from the ball. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. It is important to let the ball fall out of your hands, and not to push it down with your hands, wrists, or arms. A tennis ball is made of rubber and is covered with felt. The colder, the lower the ball bounces, and vice versa. For any other use, please contact Science Buddies. Why a ball bounces: The ball's energy is matched by the ground it hits. The impact duration was between 65 and 71 ms. This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. Keep your balls warm in order to get the best bounce possible. 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). This applies to a ball falling in a vacuum. 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. us. A glass ball will bounce higher than a rubber ball if it doesnt break. 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. Obviously, a ball won't bounce as high on carpet. 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. However, you may visit "Cookie Settings" to provide a controlled consent. If the ball bounces up more than .5 meter then, it is more elastic. This is the reason we put in our hypothesis that a balls and surfaces will ultimately be the best combination for bouncing a ball high. Use the pressure gauge to release some of the air pressure from the ball. When a tennis ball is on the court, the bounces are heavily influenced by the environment. 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. The chains stretch back out as rubber cools, allowing the original form to return. hard ball made of rubber should bounce the highest on a concrete surface, which 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. Use two people to measure the results; one person to drop the ball and one to measure the height to which it reaches after bouncing. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. This can be explained by two factors. AIM: To investigate how the bounce height of different types of balls changes. The more energy absorbed by the surface, the less that remains in the ball for it to bounce. The ball shoots back up after being slowed down. 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. 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 experiment requires a ball that will bounce and a meter stick or other measuring device. Conclusion: How Much Do Air Jordan Tennis Shoes Cost? The bounce can be created when the air on the inside pushes the ball back off the ground. Reverse Engineering: Ball Bounce Experiment Hands-on Activity Reverse Engineering: Ball Bounce Experiment (2 Ratings) Click here to rate Quick Look Partial design process Grade Level: 4 (3 - 5) Time Required: 1 hours 45 minutes (2 or 3 class periods) Group Size: 3 Subject Areas: Students investigate balls and their bounce copyright Summary To be consistent, again measure to the bottom of the ball. - Pencil x In competitive tennis, sweat loss can quickly exceed the normal body temperature, causing electrolyte and body water deficits, as well as thermal stress that can significantly alter a players physiology, perception of effort, and ability to perform well on court. Either the coefficient to restitution that was worked out is incorrect, which would mean that the first three results are inaccurate or subsequent results were inaccurate. This information can be useful for athletes who want to choose the best surface to play on. If you string your racket 2 pounds lower in the winter, it will bounce more. Place one of the tennis balls in the freezer for 20 mins 2. The harder the court surface is, the higher the rebounded ball will be. The higher the air pressure the more air particles per cubic meter. Push it against the measuring tape, careful to keep it at the same height. There were some trends observed in our As the ball has less KE and is travelling slower it becomes stationary faster at the top of its arc. It does not store any personal data. Internal air pressure is critical to the bounce of most tennis balls. The strength of Nadals forehand is what makes him so good on clay. As a result, the ball is lifted in this manner. in the execution of our experiment. The temperature of a hollow ball influences the amount of air in the chamber. 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. The equipment necessary to generate these conditions was not available and as a result the results obtained were not one hundred percent accurate. 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. Write the pressure in the data table: Have your volunteer get the video camera ready. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. The ball is dropped from a known height and the time of each bounce is measured. A cold tennis ball bounces lower than a warm one. The longer it takes to stop, the higher it bounces to. Decide on a height you want to drop the balls from . Air resistance exists but does not affect the velocity of the ball significantly. will start at 2m and then move down in intervals of 10cm to 10cm. Balls bounce in ways that are affected by gravity.
