Keep releasing pressure and repeating the experiment until the ball no longer bounces. faced. This will hopefully discount any anomalies automatically and leave us with three accurate and reliable 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. results, one of the many being that the harder the surface the ball was bouncing on, When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. Cross), Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B. Koehler), Give Me Liberty! 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. Then when dropping the ball again eye level was kept level with the blue tack. The Cold Group (-15C) averaged 53.5 cm, the Cool Group (6C) averaged 98.5 cm, the Room Temperature Group (46C) averaged 114.5 cm, the Warm Group (100C) averaged 136.5 cm, and the Hot Group (142.5 cm) averaged 142.5 cm It was determined to be correct to my hypothesis. The longer it takes to stop, the higher it bounces to. The cookies is used to store the user consent for the cookies in the category "Necessary". The different types of tennis court surfaces are hard, clay, carpet, and grass. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. Each of the following experiments tests a different hypothesis. Record the new pressure reading in your data table and repeat steps 4 and 5. This is impossible. However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. 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. Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . Materials 1. 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. 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. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball The game can be played on various surfaces, including grass, clay, and concrete. In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. The cookie is used to store the user consent for the cookies in the category "Analytics". the concrete surface is the hardest surface, it allowed more energy to be released the "bouncing balls" experiment. 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. In the heat, the molecules are more active, so the ball can bounce higher . Do different kinds of balls bounce differently? Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. In my science fair experiment, the golf ball overall was the ball that bounced the highest. It should be tall enough to hang up behind your ladder, about 5feet tall. 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. Reproduction of material from this website without written permission is strictly prohibited. KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). . First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. Our team of volunteer scientists can help. The trip is going to be thoroughly enjoyable. Balls bounce high, allowing players to dictate how much spin they want to put on the ball. Although catching small balls was an issue, we solved it by getting our better The colder the temperature, the less likely it is that the ball will bounce. The tennis balls bounce in different ways. 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. Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. Do you have specific questions about your science project? One way to do this is to put the ball in a bowl of hot water for a few minutes. Belowis the graph of h1against h2. hypothesis, we predicted that a rubber ball would bounce the highest on rough The energy goes into deforming the ball-- from its original round shape to a squashed shape. 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. ball bounced 6 inches. in the execution of our experiment. Why Does One Tennis Shoe Pull Your Sock Down? Click the "Experiment" button to find out! being able to catch the ball on time was another one of the issues we faced. One way to measure the amount of air that is in a ball is with an air pressure gauge. Once the ball hits the ground, its displacement is momentarily zero. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. 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. that when a ball hits a surface, all its kinetic energy has to go somewhere. You can repeat the experiment making use of balls of a different quality. Balls change shape during play. This is called the relative speed. The strength of Nadals forehand is what makes him so good on clay. 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. 2. Please enter a search term in the text box. Our team of volunteer scientists can help. 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. Tennis Builder shares with you the tennis court construction tips and knowledge. This is due to two factors. The higher the ball goes, the more GPE it ends up with. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. Although we had all these challenges, Experiment 2 is for testing the effect of air pressure. Here's what you need to do this experiment: Bouncy Balls - a least 6 identical balls; A measuring cup or mug for heating water in the microwave; Access to a freezer . If it bounces up less than .5 meter, then it is more inelastic. This means that KE is the same for both balls when each ball hits the ground. . 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. Carefully climb the ladder with the ball. 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. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. At 3ft, the basketball bounced 20 inches, the tennis ball bounced. This is because it is the easiest and quickest variable to alter. 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. When it hits the ground, the bottom of the ball becomes flat against the floor. Drop each ball from a distance of 1 meter onto the surface and record how high it bounces in meters (Example: .46 meters). Not 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. Push it against the measuring tape, careful to keep it at the same height. This results in faster . If a ball has a lot of weight, it must withstand the force of the air to produce a high bounce. Concrete got bounced on the most, 5 times, and the highest, 55cm. All rights reserved. Take your class outside, to an area with a smooth, flat surface. All of the factors that could have affected the results that were uncontrollable could have produced variations between results. It is also necessary to warm a ball, because the energy inside it is released. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. Then when dropping the ball again eye level was kept level with the blue tack. Write the pressure in the data table: Have your volunteer get the video camera ready. More thermal energy is also produced. This cookie is set by GDPR Cookie Consent plugin. The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. Abstract and Figures. The experiment was conducted as the method (below) states. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. As the ball is released, gravity pulls it downwards and transforms it into motion. Use the pressure gauge to release some of the air pressure from the ball. When printing this document, you may NOT modify it in any way. Let the ball bounce until it stops, and then stop recording. Warm up the ball before it is used to increase its bounce. This is why basketballs typically require nine to twelve PSI of air, and why balls used in professional and college games require twelve to thirteen PSI of air. Doherty, P., 1991. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. All rights reserved. Aim:To find out what affects the height to which a ball bounces. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. 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. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion 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. This is because it is easiest as the figure read of the meter rule is the result. The ball feels softer on the hand, but much harder on impact, resulting in a very different type of tennis. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. bounces the highest on smooth concrete. 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. on different types of surfaces, then recorded the height of the bounce. half the results (concrete), we were incorrect about the basketball. I think this is The reliability of our experiment wasn't so strong. Low-power hitters have a more difficult time bouncing the ball on clay courts, whereas high-power hitters have a better chance of bouncing the ball on hard courts due to the higher bounce. Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. As a result, they move at a slower rate of speed with less energy. This was when the ball was falling in air. 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. This cookie is set by GDPR Cookie Consent plugin. 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. 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. Prediction reasons for variable control: The height the ball is dropped from will affect the height the ball bounces to due to the energy chain the ball goes through as it is dropped and bounces up again. ping pong 2 cm 3 cm 2 cm 2 cm, basketball 82 cm 84 cm 80 82 Tiles3. As the ball falls it hits against air particles. highest on hard, smooth surfaces. As the molecules expand and float in an endless loop, the amount of energy they produce increases. Why do balls bounce higher on different surfaces? For our wind situation, one of us stood in the direction that the breeze 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. Make a line graph of your data. This blew the light balls away, giving us an unvalid result or catch. his the height of the balls bounce. It is a firm rectangular surface with a low net stretched across the centre. 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. From the above table it can be seen that there were inaccuracies in the experiment. Please enter a search term in the text box. The exact interval will be determined after the preliminary experiment, as will the number of heights that the ball will be dropped from. Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. The ball did not appear to reach its terminal velocity which also supports my prediction. small balls sometimes, but we could have improved this by taking many attempts This did not happen in my experiment however. Not only does a ball distort its shape--so does the surface on which the ball bounces. Make a note of which one bounces up higher and how high they bounce! The higher the height from which the ball was dropped from, the higher the height to which it bounced. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. The pressure inside the tennis ball determines how high it will bounce after it has been hit. Repeat the process three times with the same ball and record results. 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. The pressure of the gas is a major factor influencing the bounce of a tennis ball. We From dropping the ball we can see how high the ball will bounce to after having a loss or gain of energydue to sound or movement of the ball as it hits a hard surface. Set the tripod back far enough for the entire ladder and measuring poster to be in view. To find out what affects the height to which a ball bounces. This cookie is set by GDPR Cookie Consent plugin. Use a uniform surface to drop the ball onto. present. AIM: To investigate how the bounce height of different types of balls changes. 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. My partner and Is experiment which surface bounces a ball the highest? The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. A decrease in bounce is caused by a colder temperature. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. The colder, the lower the ball bounces, and vice versa. Which surface bounces a ball the highest? It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. 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. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. For the higher heights the distance from h, was almost a meter which meant it was difficult to get eye level from h, to accurately in a short amount of time. With this information, we. Copyright 2002-2023 Science Buddies. A cold ball will bounce farther than a warm one. hard ball made of rubber should bounce the highest on a concrete surface, which 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. There is a chance that you will bounce. Then they would be dropped from a table, and the height would be measured. it goes back into the ball, giving it more force to pop back up into the air. h1will start at 2m and then move down in intervals of 10cm to 10cm. A tennis court is the venue where the sport of tennis is played. You can even play tennis outside in any weather. (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. 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. . There were some trends observed in our Therefore the results are valid. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. By conducting our experiment, we learnt that well-inflated rubber balls bounce the If the mass of the ball is heavier the weight is heavier (weight = mg) and downward force acting upon the ball is greater as well. This is correct unless the ball shows signs of reaching terminal velocity. Vacuum pump, rigid plastic cylinder, two large rubber bungs to fit over the two ends of the plastic cylinder, table tennis ball, Two meter stick rulers. Concrete will help bounce a ball the highest as it's hard and 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. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. from the ball, therefore causing it to bounce higher than it normally would on dirt Also the mass of the ball affects the chances of the ball reaching its terminal velocity. were able to construct a successful experiment. Keep releasing pressure and repeating the experiment until the ball no longer bounces. The steel snaps back more quickly when it hits the ground. Find a clear space to work in. Cold balls tend to have a bouncier texture. will start at 2m and then move down in intervals of 10cm to 10cm. 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. . For a falling object the Coefficient to restitution (C, ) is equal to the velocity squared as the object is travelling at as it leaves the floor (v, ) divided by the velocity squared as it hits the floor (v, If a ball is dropped in a vacuum. As an Amazon Associate I earn from qualifying purchases.Privacy Policy | Affiliate Disclosure. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). However the conditions were kept the same for each drop of the ball. Why does Rafael Nadal do so well on the clay? energy a surface absorbs, the more of it will remain for a ball to bounce. Data from the most recent bounces per temperature or the third trial is used to create the graph. Why do golf balls bounce so high on concrete? For any other use, please contact Science Buddies. Let's see if physics can explain what happens. The Physics of Grass, Clay, and Cement. Therefore the ball goes higher. Measure from the bottom of the ball. 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. The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . order to give a fair experiment. Internal air pressure is critical to the bounce of most tennis balls. Use the measuring tape to measure 150 cm off the ground. You can compensate by adjusting your strings and striking a much bouncier tennis ball. The temperature of a tennis ball can affect its bounce height. Therefore the heavier the ball is, the faster its terminal velocity. Masses of tennis balls range between 56.0 and 59.4 grams (2011). Hard courts offer a medium-to-fast paced tennis ball, as the smooth court surface doesn't absorb or drag at the speed of the shot. Section II: Hypothesis. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. 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. will differ from the height that the ball would have reached had it been dropped in a vacuum. The weight and material of the ball will be kept the same throughout the experiment by using the same ball. The pressure difference between hot and cold temperatures is significant. Science Buddies: Pilobolus Spore Sac Launch. This causes thermal energy to be given off. 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. Reproduction of material from this website without written permission is strictly prohibited. Conclusion: I will drop the ball 3 The air pressure within the hollow ball changes as the temperature rises. the initial bounce height is 1 m). Overall, our experiment taught us that harder Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. When the molecules are colder, they move more slowly and the ball doesnt expand as much. 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. Repeat step 5 with all of your other surfaces. Method: 1. The first independent variable that will be tested. The procedure allowed me to observe the affects of the height from which a table tennis ball was dropped from upon the height to which it bounced. 3. 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. How can you measure the height a ball bounces? Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. 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. Its not just a game for the wealthy; its also a game for everyone. - Ping pong ball x However when the ball is dropped from a relatively low height, drag 0. 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. 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. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. Analytical cookies are used to understand how visitors interact with the website. When the temperature drops, gas molecules in close proximity. If we 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. Introduction: From the above table it can be seen that there were inaccuracies in the experiment. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. The bounce of a cold superball is shorter than that of a warm superball. Some of the balls energy can be converted into heat. 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. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. METHOD: 1. Now use your data table to plot points on the graph. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. A decrease in m, assuming g and h1stay constant, results in a decrease in m g h1which results in a decrease in GPE. But what makes a ball bounce? Then draw a line to connect the dots. 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.
