Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion The cookie is used to store the user consent for the cookies in the category "Analytics". Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. Then they would be dropped from a table, and the height would be measured. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. 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. small balls sometimes, but we could have improved this by taking many attempts 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. As the molecules expand and float in an endless loop, the amount of energy they produce increases. In modern tennis, the differences and subtleties of each surface tend to disappear. Why do marbles bounce so high? . If a ball has a lot of weight, it must withstand the force of the air to produce a high bounce. 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. When the ball hits the floor and stops, that energy has to go somewhere. 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. 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. Which surface bounces a ball the highest? 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. Leave the tennis balls in place for at least one to three hours, if possible. As an example, on the day we performed our experiment, a strong wind was 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. Let the ball bounce until it stops, and then stop recording. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. Measuring tape 3. energy a surface absorbs, the more of it will remain for a ball to bounce. Observe the height of the 1st rebound height of the tennis ball. Masses of tennis balls range between 56.0 and 59.4 grams (2011). 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. "Balls Bouncing Off of Surfaces.". The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. 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. It will not have enough force to bounce if it is lit. If it bounces up less than .5 meter, then it is more inelastic. This means that the faster that the ball travels the larger the force of air resistance upon it. Why Tennis Balls Bounce. The changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. This would eliminate parallax error further. Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Why a ball bounces: The ball's energy is matched by the ground it hits. Take your class outside, to an area with a smooth, flat surface. Science Buddies: Pilobolus Spore Sac Launch. When it reaches Earth, it collides head-on with an . Each of the following experiments tests a different hypothesis. 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. This proves that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. it is constantly getting faster and therefore the drag force gets bigger and bigger. This still took us time and we still couldn't catch the I used a Flexible measuring tape to measure. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. What material makes a ball bounce higher? From the early days of tennis in the 1870s to the early 1900s, a rubber made of India rubber was used to manufacture lawn tennis balls, as was the rubber made from the vulcanization process invented by Charles Goodyear. order to give a fair experiment. This results in faster . A lot of Now, take your video and watch it to gather your data. 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. Reproduction of material from this website without written permission is strictly prohibited. (Doherty, 1991). Bending Plant Roots with Gravity Lesson Plan Introduction. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. 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. If a ball reaches terminal velocity at 20cm from the floor when dropped from 2m, it will reach terminal velocity at 10cm from the floor when dropped from 1.9m. 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. Best hard court players of all time You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. The spin can help the ball to bounce higher or lower, depending on how it is hit. concur, which was catching the small balls. energy a surface absorbs, the more of it will remain for a ball to bounce. The Physics of Grass, Clay, and Cement. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. 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. It is also necessary to warm a ball, because the energy inside it is released. The experiment was conducted as the method (below) states. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. But what makes a ball bounce? Copyright 2002-2023 Science Buddies. The ball showed signs of reaching terminal velocity because the drag force began to approach the force gravity exerts upon the mass of the ball. Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped.

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. Repeat the process three times with the same ball and record results. The cookie is used to store the user consent for the cookies in the category "Performance". 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. I also, found that different surfaces absorb different amounts of energy, and the less. The steel has a lot of bounce power due to its better storage of energy. Why does a tennis ball bounce higher on concrete? Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. . Do you have specific questions about your science project? For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. Keep releasing pressure and repeating the experiment until the ball no longer bounces. The average variation between results was 3cm. The energy that the ball hits the floor with is kinetic energy. 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. This is why it. The cookie is used to store the user consent for the cookies in the category "Other. Keep a close eye on the ball, and instruct Phlebas to do the same. The tennis balls bounce in different ways. Do you have specific questions about your science project? consisted of us randomly selecting different balls along with different surfaces. The bounce of the ball is a major factor in the game of tennis. As a result, the balls bounce decreases as pressure decreases. This means it will be travelling the same speed when it hits the ground. Keep your balls warm in order to get the best bounce possible. This is correct unless the ball shows signs of reaching terminal velocity. In my science fair experiment, the golf ball overall was the ball that bounced the highest. 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. an incorrect and unreliable result. 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. Do five drops on your first surface. Hypothesis. The coefficient to restitution can be found out from a graph of, it follows the gradient of the graph change in h. . For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. Launch Related Video : The Hawk Factor. The balls bounced higher on the concrete This means that not all the GPE is converted into KE as it would have been if the ball had been dropped in a vacuum. The felt helps to create spin on the ball when it is hit with a racket. The higher h1, the faster the velocity that the ball reaches. solid. This is impossible. - Rubber ball x The reliability of our experiment wasn't so strong. We also use third-party cookies that help us analyze and understand how you use this website. 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. How does the material of a ball affect its bounce? troubles my partner and I had during our experiment along with the problems we KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). 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. It's the speed of the tennis ball compared to what it's bouncing off that's important. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? A decrease in bounce is caused by a colder temperature. his the height of the balls bounce. 70% is retained. Air resistance exists but does not affect the velocity of the ball significantly. Drop (do not throw) the ball from a carefully measured height using the meter stick. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. 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. Obviously, a ball won't bounce as high on carpet. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. It is a firm rectangular surface with a low net stretched across the centre. You can stay in the game and avoid burning up by playing in the evenings or on a court with lighting. Record the new pressure reading in your data table and repeat steps 4 and 5. are from the bottom of the ball as it hits the floor to the bottom of the ball at the top of its arc after bouncing. The harder the court surface is, the higher the rebounded ball will be. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. hypothesis, we predicted that a rubber ball would bounce the highest on rough 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. 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. Please enter a search term in the text box. A tennis ball is made of rubber and is covered with felt. The steel snaps back more quickly when it hits the ground. Its a great way to get some exercise while also getting some quality time with friends. It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. As the ball has less KE and is travelling slower it becomes stationary faster at the top of its arc. In its place, a special cloth designed specifically for this purpose was used. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. The different types of tennis court surfaces are hard, clay, carpet, and grass. 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. Parallax error will be avoided by dropping the ball one time that will not be measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. Not This means that the higher h. will differ from the height that the ball would have reached had it been dropped in a vacuum. 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. Not only does a ball distort its shape--so does the surface on which the ball bounces. The balls finish up with the same amount of energy and the only energy given out is thermal energy. If you play in hot weather, your balls may bounce significantly more. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. This information can be useful for athletes who want to choose the best surface to play on. Because of this, a fully inflated ball may look deflated if the temperature drops quickly. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. 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. What factors affect the bounce height of a ball? You can check the weather stats at. C. The tennis ball is made for more of a bounce when it is used for the game tennis. The experiment was conducted well however as the utmost efforts were brought into place to avoid parallax error and it was ensured as far as possible that factors that affected how high the ball bounced, excluding the height, were kept constant throughout the experiment. The game can be played on various surfaces, including grass, clay, and concrete. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. Find a clear space to work in. Therefore, is well-inflated and made of rubber which would give it more kinetic energy and We then bounced the balls on the surfaces and 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 is because it is the easiest and quickest variable to alter. 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. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. You can even play tennis outside in any weather. Try bouncing different kinds of balls to test this question. to find out which surface bounces a ball the highest. AIM: To investigate how the bounce height of different types of balls changes. 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. This is called the relative speed. Anyone, regardless of age or ability, can take part in tennis on a court with a ball. The first independent variable that will be tested. Let's see if physics can explain what happens. September 28, 2022 by George Jackson. 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. 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. (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. As there is more KE, more energy is converted into elastic potential energy, As there is more elastic potential energy, more energy is converted back into KE energy. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). Therefore the results are valid. It does not store any personal data. Method: 1. Once the drag force equals the gravitational force all forces are equal and acceleration stops. This is because the experiment is a very short and simple one to carry out and if conducted efficiently can be completed easily within the time span allowed for collecting evidence. Therefore the heavier the ball is, the faster its terminal velocity. This means that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. This is because it is easiest as the figure read of the meter rule is the result. 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. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. Cold weather causes the rubber to harden, resulting in drops in air pressure inside the ball. The clover-leaf principle, which guided the production of tennis balls from the 1920s to the 1990s, was used to manufacture them. The ball did not appear to reach its terminal velocity which also supports my prediction. were able to construct a successful experiment. us. To a wider range of results i.e. Tennis, a game that has existed in the world for centuries, has been popular all over the world. This did not happen in my experiment however. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. , v is greater therefore KE is greater by a larger amount). To be consistent, again measure to the bottom of the ball. These cookies track visitors across websites and collect information to provide customized ads. it goes back into the ball, giving it more force to pop back up into the air. Balls bounce up to 5 . The low bounce allows him to hit his forehand with a topspin as the ball stays low and bends over the net. A glass ball will bounce higher than a rubber ball if it doesnt break. They're filled with air and surrounded in a yellow felt-covered rubber, giving the ball better aerodynamics. Then when it bounces up, it returns to its original shape. experiment. There is a chance that you will bounce. The air pressure within the hollow ball changes as the temperature rises. Aim:To find out what affects the height to which a ball bounces. 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. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. Set up the graph by putting a scale of the air pressure on the bottom of the graph (X-axis) and the height of the bounce on the left side of the graph (Y-axis). 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. "That's The Way The Ball Bounces," The Exploratorium Museum, San Francisco, CA. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. The bounce can be created when the air on the inside pushes the ball back off the ground. The height of the ball at each bounce is then calculated. the higher it popped up into the air. All rights reserved. But opting out of some of these cookies may affect your browsing experience. ping pong 2 cm 3 cm 2 cm 2 cm, basketball 82 cm 84 cm 80 82 Write the pressure in the data table: Have your volunteer get the video camera ready. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. 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. Try your bounce test in different weather conditions. bounces the highest on smooth concrete. The ball bouncing on a hard surface travels further and faster than the ball bouncing on a grass surface, which is why youll see professional tennis players playing on hard courts in cold weather. Push it against the measuring tape, careful to keep it at the same height. Reproduction of material from this website without written permission is strictly prohibited. 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. Experiment 2 is for testing the effect of air pressure. 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. Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. Therefore of the GPE that the ball possessed at the beginning some energy is given off as thermal energy. Kinetic energy and ball shape.
