tennis ball bounce on different surfaces experiment
Drop each ball from a distance of 1 meter onto the surface and record how high it bounces in meters (Example: .46 meters). These cookies ensure basic functionalities and security features of the website, anonymously. = The distance between the bottom of the ball before it is dropped and the ground. There were some trends observed in our This is impossible. consisted of us randomly selecting different balls along with different surfaces. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Place the tape measurer against the edge of a wall using the bluetack 3. However, you may visit "Cookie Settings" to provide a controlled consent. Copyright 2002-2023 Science Buddies. Determine how high the ball rebounds on its first bounce. This will be called the average of the middle three repeats. The Physics of Grass, Clay, and Cement. 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. C. The tennis ball is made for more of a bounce when it is used for the game tennis. Air density will not change enough to affect the flight of the ball seeing as all the results will be collected during a brief period on one day. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. 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. 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. or carpet. 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. If we 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 the ball falls to the surface it has kinetic energy. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. There is an activity at home that can be used to investigatebounciness. During the research fraction of the experiment, it was Push it against the measuring tape, careful to keep it at the same height. - Paper x 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. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. If the ball bounces up more than .5 meter then, it is more elastic. highest on hard, smooth surfaces. - Sticky tape - 1 roll. This means that KE is the same for both balls when each ball hits the ground. This is because it is the easiest and quickest variable to alter. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. If it bounces up less than .5 meter, then it is more inelastic. 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/Phys_p039/physics/balls-bouncing-off-of-surfaces. This would eliminate parallax error further. The energy goes into deforming the ball-- from its original round shape to a squashed shape. Which surface bounces a ball the highest? Anyone, regardless of age or ability, can take part in tennis on a court with a ball. Its not just a game for the wealthy; its also a game for everyone. Take a ball and place it on the 150 cm line and drop it. The more particles per cubic meter, the more drag acting upon the ball. For a falling object the Coefficient to restitution (CR) is equal to the velocity squared as the object is travelling at as it leaves the floor (v22) divided by the velocity squared as it hits the floor (v12): If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h1 and CR. "That's The Way The Ball Bounces," The Exploratorium Museum, San Francisco, CA. What affects ball bounce? experiment. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. was proven correct after our experiment. 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. (2020, November 20). Science Buddies Staff. 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. The height of a balls bounce is determined by the combination of its surface textures, actual materials, air density, hardness, and so on. Balls bounce up to 5 . Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. 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. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. present. This means that we can approximately calculate the amount of energy that the ball conserves as it hits the floor and therefore the height to which it will bounce for any given height in a vacuum. Two different types of balls, Penn Championship and Non-Championship will be compared. The balls bounced higher on the concrete A tennis balls trajectory is determined by its temperature. This website uses cookies to improve your experience while you navigate through the website. The height of the ball at each bounce is then calculated. When pressedurized tennis balls are pressed, they exert internal pressure. Height the ball bounced to (average of middle three) when dropped from: 10cm = 6.7 6.7 = 66% of 10 (to the nearest percent), 20cm = 14.0 14.0 = 70% of 20 (to the nearest percent), 30cm = 22.3 22.3 = 74% of 30 (to the nearest percent). 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. - Rubber ball x Cross), Forecasting, Time Series, and Regression (Richard T.

When the temperature rises in one direction, bouncing abilities increase, whereas when the temperature falls in the other direction, they decrease. we were able to work our way around them, giving us a more successful Grades: Preschool and K-2. were able to construct a successful experiment. The tennis balls bounce in different ways. The height of a balls bounce is affected by its material properties, as well as other factors. Tennis balls are more likely to bounce on grass. In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. Do you have specific questions about your science project? Which ball will bounce higher off a hard surface? It does not store any personal data. 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. Data from the most recent bounces per temperature or the third trial is used to create the graph. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. A cold ball will bounce farther than a warm one. The drag force increases as the ball goes faster. 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. This means it will be travelling the same speed when it hits the ground. 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. 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. - tennis ball x Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. As a result, the ball is lifted in this manner. Height will be the variable that we will vary. This cookie is set by GDPR Cookie Consent plugin. Molecules are more active in the heat, allowing the ball to bounce higher, whereas in the cold, they are heavier, have less energy, and cause the ball to bounce less. As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. For any other use, please contact Science Buddies. 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. the "bouncing balls" experiment. When printing this document, you may NOT modify it in any way. Friday - 25/04/14 For instance result 3 from 200cm was an anomaly but was not taken into account when taking the average of the middle three. h1will start at 2m and then move down in intervals of 10cm to 10cm. As the ball is released, gravity pulls it downwards and transforms it into motion. What do you think this means about your results? As velocity increases air resistance increases in proportion to the square of the velocity. 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. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. Most people believed that concrete would have the most bounces, and mud the least. This can be explained by two factors. 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. Balls bounce in ways that are affected by gravity. 70% is retained. Does height make a difference? According to the USTA regulations ball is tested for bounce by dropping it from a height of 100 inches (2.54 m) onto ; a bounce between 53 and 58 inches (1.3462 - 1.4732 m) is acceptable. As in both cases the main form of energy is GPE it follows that the higher the ball is dropped from, the higher the ball will bounce. an incorrect and unreliable result. Drop (do not throw) the ball from a carefully measured height using the meter stick. One way to do this is to put the ball in a bowl of hot water for a few minutes. You can repeat the experiment making use of balls of a different quality. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. The impact duration was between 65 and 71 ms. Most experiments investigate the effect of an independent variable on a dependent variable. If the elastic potential energy is the same then the same amount of energy is converted back into KE and so the balls leave the floor at the same speed. The surface onto which the ball is dropped upon will be kept the same. As the ball falls it hits against air particles. (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. It should be on a smooth cement surface for optimal ball bouncing. Why do golf balls bounce so high on concrete? As for catching the balls on time, we changed our hand positioning and Set the tripod back far enough for the entire ladder and measuring poster to be in view. A totally accurate experiment would have a variation between results equal to zero however an experiment that is totally accurate needs to be conducted under conditions where air pressure and temperature remained constant, error produced by the ball falling on different parts of the linoleum floor tile (which was not totally even and thus produces inaccurate results) and human error removed by dropping the ball onto a uniform surface and using machinery to record the height to which the ball bounced to. concrete, in which we were incorrect. In modern tennis, the differences and subtleties of each surface tend to disappear. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. When printing this document, you may NOT modify it in any way. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. "Balls Bouncing Off of Surfaces.". The ball weighs exactly 2.5g. will differ from the height that the ball would have reached had it been dropped in a vacuum. is well-inflated and made of rubber which would give it more kinetic energy and Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. Tennis balls are different at sea level and at high altitudes. Tiles3. This experiment would provide me with more results that are relevant to the experiment that I have already conducted. 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. Kinetic energy and ball shape. You can check the weather stats at. surface bounces a ball the highest. A tennis ball is made of rubber and is covered with felt. Repeat the process three times with the same ball and record results. In the heat, the molecules are more active, so the ball can bounce higher . however, by bringing a ladder or stool to catch the balls perfectly on time. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. (Doherty, 1991). 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). Also the difference between the force of air resistance acting upon a ball travelling at 1ms-1 and the force of air resistance acting upon a ball travelling at 2ms-1 is far smaller than the difference between the force of air resistance acting upon a ball travelling at 20ms-1 and the force of air resistance acting upon a ball travelling at 21ms-1. 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. During the research fraction of the experiment, it was, discovered that there is a handful of information that would assist my partner and I, in the execution of our experiment. H is the height of the ball before it is dropped. 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. All rights reserved. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. his the height of the balls bounce. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. Repeat steps 1-6 with the different balls. 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. Materials 1. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Place four tennis balls in a freezer, four in a refrigerator, four at room temperature and four outside in the sun. 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. troubles my partner and I had during our experiment along with the problems we It is also necessary to warm a ball, because the energy inside it is released. Once the drag force equals the gravitational force all forces are equal and acceleration stops. This cookie is set by GDPR Cookie Consent plugin. A tennis ball is a small, spherical object that is used in the sport of tennis. September 28, 2022 by George Jackson. (2020, January 12). The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". Graph 1. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. The Swiss like to get points over and done with in a short period of time. In this manner, you apply heat shrink to your head and heat it up until the shrink shrinks. Therefore the height that it reaches is less high. 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. I also The dependence of the speed or pace of the court on the coefficient of friction (COF) as well as the coefficient of restitution (COR) is derived. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. 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. was blowing in, so that if the balls were blown away, they would come straight to Why do balls bounce higher on different surfaces? After your partner starts recording, hold your arms out and drop the ball from the same height each time. , v is greater therefore KE is greater by a larger amount). When the ball hits the floor and stops, that energy has to go somewhere. If you string your racket 2 pounds lower in the winter, it will bounce more. It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. Record the new pressure reading in your data table and repeat steps 4 and 5. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. 30% of the energy that the ball hits the floor wit is lost. 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. [accessed August 4, 2006]. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. to find out which surface bounces a ball the highest. A lot of Do different kinds of balls bounce differently? Science Buddies Staff. 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. With this information, we 15 inches, and the golf ball bounced 26 inches. Now, take your video and watch it to gather your data. Therefore the coefficient to restitution = 0.7. Then when it bounces up, it returns to its original shape. 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. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball Why does a tennis ball bounce higher on concrete? When dropped on a solid surface, not even a super ball bounces back as high as its initial height, but some balls do bounce a lot better than others. The 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. Focus. The bounce should be between 53 and 58 inches. rubber ball 39 cm 38 cm 41 cm 39 cm. An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. With this information, we. energy a surface absorbs, the more of it will remain for a ball to bounce. The strength of Nadals forehand is what makes him so good on clay. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. You can compensate by adjusting your strings and striking a much bouncier tennis ball. A similar length stick, marked in 5-10cm bands of colour. Experiment Click the following buttons to skip to a page. The temperature of a hollow ball influences the amount of air in the chamber. This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. 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 will be a table tennis ball. Launch Related Video : The Hawk Factor. The cookie is used to store the user consent for the cookies in the category "Other. It is a firm rectangular surface with a low net stretched across the centre. 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. the concrete surface is the hardest surface, it allowed more energy to be released Ball trial 1 trail 2 trial 3 average It was more reliable to use the middle three results as it automatically discounted any anomalies; assuming two similar anomalies were recorded for one height, if they were then they both would be discounted. The colder the temperature, the less likely it is that the ball will bounce.

To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. Section II: Hypothesis. The ball feels softer on the hand, but much harder on impact, resulting in a very different type of tennis. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. Introduction: Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. These two results were excluded when averages were being calculated and therefore the average variation between results used for calculating the average was even less than 3cm. Make a line graph of your data. It will be vinyl tiling. The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. METHOD: 1. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. 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.
