Write your measurements down. A tennis court is the venue where the sport of tennis is played. The decision for the size of interval and the amount of results collected will depend upon the time taken to conduct the experiment and any other factors that may become apparent during the preliminary experiment. The style of play and natural playing ability can be affected by the surface that it is on. The temperature of the tennis ball has an impact on its bounce. The steel snaps back more quickly when it hits the ground. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. The tennis balls bounce in different ways. Height will be the variable that we will vary. - Measuring tape x Kinetic energy and ball shape. 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. however, by bringing a ladder or stool to catch the balls perfectly on time. Concrete4. The bounce of a cold superball is shorter than that of a warm superball. Tennis balls bounce differently in the high altitude and at sea. A tennis ball is made of rubber and is covered with felt. Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. 2. Click the "Experiment" button to find out! 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. us. "Balls Bouncing Off of Surfaces.". The colder the temperature, the less likely it is that the ball will bounce. Do you have specific questions about your science project? 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. The harder the court surface is, the higher the rebounded ball will be. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. The higher h1, the faster the velocity that the ball reaches. This results in faster . Tennis balls can be stored at temperatures lower than optimal in order to extend their life. Section II: Hypothesis. Equipment/materials used: However the conditions were kept the same for each drop of the ball. results, one of the many being that the harder the surface the ball was bouncing on, 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. There is a chance that you will bounce. we were able to work our way around them, giving us a more successful . Reproduction of material from this website without written permission is strictly prohibited. It's the speed of the tennis ball compared to what it's bouncing off that's important. I think this is A cold tennis ball bounces lower than a warm one. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. 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. Changes in the area of linoleum floor tile that the ball collided with may have affected the height to which it bounced to thus producing variation between results. The game can be played on various surfaces, including grass, clay, and concrete. Keep a close eye on the ball, and instruct Phlebas to do the same. Try your bounce test in different weather conditions. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. Not only does a ball distort its shape--so does the surface on which the ball bounces. The maximum and minimum results were included when working out the variation between results however, seeing as the maximum and minimum results were produced by the experiment and are therefore part of the variation between results produced by the experiment. Tennis balls are more likely to bounce on grass. harder surfaces will ultimately bounce a ball higher. h1will start at 2m and then move down in intervals of 10cm to 10cm. Record the new pressure reading in your data table and repeat steps 4 and 5. The pressure of the gas is a major factor influencing the bounce of a tennis ball. The ball shoots back up after being slowed down. To find out what affects the height to which a ball bounces. The variation between results was obtained by taking the minimum result away from the maximum result. Do different kinds of balls bounce differently? 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. 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 energy chain is as follows: Therefore as energy cannot be created or destroyed the energy the ball starts with must be directly proportional to the energy the ball finishes with, at the top of its bounce, and so if the ball starts with more energy it must therefore finish with more. experiment. faced. Use a uniform surface to drop the ball onto. 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. (Doherty, 1991). Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. Abstract and Figures. 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. The grass does not provide as much upward rebound when the ball hits it. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. Make a note of which one bounces up higher and how high they bounce! A decrease in bounce is caused by a colder temperature. Please enter a search term in the text box. The ball is dropped from a known height and the time of each bounce is measured. The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. 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. Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. This applies to a ball falling in a vacuum. Each ball in a can is different in weight, diameter, and bounce. This would mean that one could re-examine the height to which it bounced to and find it exactly instead of having to make a split second judgement which is not half as accurate. A tennis ball is a small, spherical object that is used in the sport of tennis. When printing this document, you may NOT modify it in any way. surface bounces a ball the highest. We then bounced the balls on the surfaces and The reason is that the molecules in the ball are more active when they are warmer, so they push against each other harder, and the ball expands more. would bounce the highest on a hard, smooth concrete surface because a rubber ball Science Buddies Staff. Why do marbles bounce so high? A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. A lot of As the temperature rises, the gas molecules in the tennis ball expand. September 28, 2022 by George Jackson. Two different types of balls, Penn Championship and Non-Championship will be compared. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. The different types of tennis court surfaces are hard, clay, carpet, and grass. This cookie is set by GDPR Cookie Consent plugin. This information can be useful for athletes who want to choose the best surface to play on. hard ball made of rubber should bounce the highest on a concrete surface, which You can also try using a hair dryer to heat the ball up. Some of the kinetic energy of the ball is lost during the collision with the floor and the ball will not return to the original height. H is the height of the ball before it is dropped. The maximum height will have to be less than two meters as that is the maximum height that the equipment allows. 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. an incorrect and unreliable result. small balls sometimes, but we could have improved this by taking many attempts The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. 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. The strength of Nadals forehand is what makes him so good on clay. Determine how high the ball rebounds on its first bounce. To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. This is due to an inelasticity in the energy lost when the ball collides with the ground, as well as the fact that the ball bounces every time it is hit. the concrete surface is the hardest surface, it allowed more energy to be released External factors, i.e. Launch Related Video : The Hawk Factor. As for catching the balls on time, we changed our hand positioning and Then when it bounces up, it returns to its original shape. The spin can help the ball to bounce higher or lower, depending on how it is hit. Decide on a height you want to drop the balls from . A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. found that different surfaces absorb different amounts of energy, and the less KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). At 3ft, the basketball bounced 20 inches, the tennis ball bounced. For instance, you can use old balls for the second round of the experiment compared to new balls. This is a result of the It will be vinyl tiling. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? My partner and Is experiment which surface bounces a ball the highest? When it is dropped, the air molecules will squish together and then spring apart. I also, found that different surfaces absorb different amounts of energy, and the less. was blowing in, so that if the balls were blown away, they would come straight to GPE=Mass (kg) Gravitational Field Strength (N/Kg) Height (m). The ball weighs exactly 2.5g. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. Not The Modus 120 pickup enables you to produce some of the most amazing sound combinations. Why do balls bounce higher on different surfaces? 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. In the heat, the molecules are more active, so the ball can bounce higher . measured the heights. 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. his the height of the 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. This causes thermal energy to be given off. Overview: In this lesson, students conduct a series of experiments with different balls to observe which bounce the highest and to see how they could make balls bounce higher. Is it a straight line? Does a tennis ball bounce differently on different surfaces? The Physics of Grass, Clay, and Cement. As the height from which the ball was dropped from was increased, the GPE energy that the ball possessed before being dropped also increased. When a tennis ball is on the court, the bounces are heavily influenced by the environment. Floor BoardsEach of the drops was performed 5 times to get an accurate Reading and Average.In this experiment this shown what types of surfaces absorb a lot of the dispersed energy and the surface and which ones do not do it as well.This was done on iMovie and took 2 Hours to Create.So Please Enjoy! 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. 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. 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. However when the ball is dropped from a relatively low height, drag 0. Ball trial 1 trail 2 trial 3 average Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. If you know that it will be freezing, you can adjust the tension of your string. Although we were correct about Tennis, a game that has existed in the world for centuries, has been popular all over the world. 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. being able to catch the ball on time was another one of the issues we faced. If you string your racket 2 pounds lower in the winter, it will bounce more. 3. However, you may visit "Cookie Settings" to provide a controlled consent. - Ping pong ball x It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. 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. But opting out of some of these cookies may affect your browsing experience. Write each measurement in the data table. 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. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. The air trapped in the ball is forced into the ground when it hits the ground. 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. Why does a tennis ball bounce higher on concrete? It should be on a smooth cement surface for optimal ball bouncing. Repeat step 5 with all of your other surfaces. 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. As the ball falls to the surface it has kinetic energy. In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. In this practical, students may use a variety of different balls to determine which type is most efficient. 30% of the energy that the ball hits the floor wit is lost. Push it against the measuring tape, careful to keep it at the same height. The Swiss like to get points over and done with in a short period of time. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. 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. In this experiment you will use a ball filled with air. 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.
