September 28, 2022 by George Jackson. 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. Copyright 2002-2023 Science Buddies. If you want to make the ball bounce lower, you can try cooling it down by putting it in the fridge or freezer for a few minutes. C. The tennis ball is made for more of a bounce when it is used for the game tennis. The children were oblivious to these . The same surface can be used to play both doubles and singles matches. This would eliminate parallax error further. Use a uniform surface to drop the ball onto. Drop each ball from a distance of 1 meter onto the surface and record how high it bounces in meters (Example: .46 meters). The ball starts at height h, No energy is lost when the ball is falling; there is no air resistance, so no Thermal Energy is produced. Equipment/materials used: Science Buddies: Pilobolus Spore Sac Launch. 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. Observe the height of the 1st rebound height of the tennis ball. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. the concrete surface is the hardest surface, it allowed more energy to be released h1and h2are 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 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. EQUIPMENT: 1 metre ruler 1 table tennis ball. . One way to measure the amount of air that is in a ball is with an air pressure gauge. From this it can be seen that using the average of the middle three results is more accurate than using the average of all five, as it automatically discounts most anomalies. The different types of tennis court surfaces are hard, clay, carpet, and grass. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. Therefore the height that it reaches is less high. As a result, they move at a slower rate of speed with less energy. Also it will affect its bouncing properties.

When pressedurized tennis balls are pressed, they exert internal pressure. Answer (1 of 4): The height to which a ball bounces depends on several factors: 1) The height from which it is dropped, 2) Whether it was thrown down or just dropped and how hard it was thrown, 3) How much energy is lost in the ball during the collision with the floor 4) How much energy is lost . Why do golf balls bounce so high on concrete? STEP4 - Watch as the smaller ball flies off into the air! I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. An alternative method would be the measuring person holding a video camera level with the approximate height that the ball reaches after bouncing and videoing the ball reach the top of its arc. Copyright 2002-2023 Science Buddies. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. This would allow one to find the terminal velocity of the ball. 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. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. These both support my prediction and show that my prediction was correct. Make a line graph of your data. 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. Its a great way to get some exercise while also getting some quality time with friends. This blew the light balls away, giving us an unvalid result or catch. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. Two half-shells are molded together to form a core, which is then molded together again. old and new tennis balls (different surface textures/ages). During the preliminary experiment it was established that time was not an important factor that had to be taken into account when deciding how many different heights to drop the ball from and the interval between those heights. The longer it takes to stop, the higher it bounces to. This is a result of the 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). Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Increased energy and movement results in a bounce. 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. What was the outcome? The balls finish up with the same amount of energy and the only energy given out is thermal energy. 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. - Sticky tape - 1 roll. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. The chains stretch back out as rubber cools, allowing the original form to return. Science Buddies Staff. Therefore, harder surfaces will ultimately bounce a ball higher. 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. According to our background research, a 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. Therefore the height the ball bounces will be proportional to the height that the ball is dropped from up to a certain point, where the ball begins to show signs of reaching its terminal velocity before it reaches the ground. Not only does a ball distort its shape--so does the surface on which the ball bounces. The cookies is used to store the user consent for the cookies in the category "Necessary". 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. How does the material of a ball affect its bounce? All rights reserved. A tennis balls trajectory is determined by its temperature. In my science fair experiment, the golf ball overall was the ball that bounced the highest. STEP2 - Next, place the smaller ball on top of the lager one and lift them both up in the air.. STEP3 - Drop em'!. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. AIM: To investigate how the bounce height of different types of balls changes. 1. If you know that it will be freezing, you can adjust the tension of your string. The maximum height will have to be less than two meters as that is the maximum height that the equipment allows. 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. There are many other great ball projects in this fun book by Madeline P. Goodstein. h1 = The distance between the bottom of the ball before it is dropped and the ground. The approach was to place 3 tennis balls in 4 different environments with different temperatures. Above this point the height all balls will bounce to will not be directly proportional to the height they are dropped from, but the increase in the height they bounce to will increase more slowly in proportion to the height they are dropped from compared to the increase between lower heights before the ball shows signs of approaching its terminal velocity before it hits the ground. When it is dropped, the air molecules will squish together and then spring apart. small balls sometimes, but we could have improved this by taking many attempts Our team of volunteer scientists can help. The ball weighs exactly 2.5g. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion The variation between results was obtained by taking the minimum result away from the maximum result. 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. I think this is 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. Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). This is the reason we put in our hypothesis that a Then draw a line to connect the dots. To be consistent, again measure to the bottom of the ball. 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. 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. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. Keep releasing pressure and repeating the experiment until the ball no longer bounces. An investigation into how they impact play on the court. 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! This cookie is set by GDPR Cookie Consent plugin. troubles my partner and I had during our experiment along with the problems we discovered that there is a handful of information that would assist my partner and I Repeat the process three times with the same ball and record results. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. Experiment Click the following buttons to skip to a page. Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. This is why it h2will 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. Abstract and Figures. measured the heights. You can also try using a hair dryer to heat the ball up. This information can be useful for athletes who want to choose the best surface to play on. 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. 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. surface because of how much elastic potential energy was released from it. Therefore any change to the height from which the ball starts with affects the height to which it bounces to. - Four surfaces (carpet, rough concrete, dirt and smooth concrete). This is because it is easiest as the figure read of the meter rule is the result. As an example, on the day we performed our experiment, a strong wind was A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. 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. Reproduction of material from this website without written permission is strictly prohibited. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. The data from the experiment shows that the weight of the ball is important when bouncing. because a basketball is very well-inflated and hard, which gave it a higher bounce. 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. An increase in h1, assuming g and m stay constant, results in an increase in m g h1 which results in an increase in GPE. 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. 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. 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. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. The effect of surface on the bounce height of a tennis ball. the higher it popped up into the air. As for catching the balls on time, we changed our hand positioning and The air trapped in the ball is forced into the ground when it hits the ground. Now use your data table to plot points on the graph. A decrease in bounce is caused by a colder temperature. highest on hard, smooth surfaces. 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. The temperature of a tennis ball greatly affects how high it bounces. Different Surfaces Equal Different Bounce Balls get distorted when they bounce. By conducting our experiment, we learnt that well-inflated rubber balls bounce the 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. This did not happen in my experiment however. - tennis ball x This will hopefully discount any anomalies automatically and leave us with three accurate and reliable results. The balls bounced higher on the concrete The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. The coefficient to restitution can be found out from a graph of, it follows the gradient of the graph change in h. . For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. What factors affect the bounce height of a ball? This is due to two factors. Therefore the ball ends up with more GPE, , assuming g and m stay constant, results in an increase in m g h, , assuming g and m stay constant, results in a decrease in m g h, As the ball is accelerating due to gravity, at 9.81m/s. There is a chance that you will bounce. It will not have enough force to bounce if it is lit. the initial bounce height is 1 m). from the ball, therefore causing it to bounce higher than it normally would on dirt 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. Reverse Engineering: Ball Bounce Experiment Hands-on Activity Reverse Engineering: Ball Bounce Experiment (2 Ratings) Click here to rate Quick Look Partial design process Grade Level: 4 (3 - 5) Time Required: 1 hours 45 minutes (2 or 3 class periods) Group Size: 3 Subject Areas: Students investigate balls and their bounce copyright Summary This is correct unless the ball shows signs of reaching terminal velocity. Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. 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 height of a balls bounce is determined by the combination of its surface textures, actual materials, air density, hardness, and so on. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). When the ball is pulled toward the ground, gravity slows it down so that it doesn't bounce as many times. Internal air pressure is critical to the bounce of most tennis balls. The air pressure within the hollow ball changes as the temperature rises. rubber ball 39 cm 38 cm 41 cm 39 cm. It was decided that the first drop would start at 2m off the floor and then move down in intervals of 10cm to 10 cm off the floor. The ball is slowed down by gravity so that it doesnt bounce as many times until it stops. Keep a close eye on the ball, and instruct Phlebas to do the same. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. carpet, tennis 57 cm 56 cm 61 cm 58 cm concrete, in which we were incorrect. There are more than 160 different types of tennis surfaces. If the coefficient to restitution = 0.7, a ball dropping from h, in a vacuum would reach the height of 0.7 h, As velocity increases air resistance increases in proportion to the square of the velocity. Cold weather causes the rubber to harden, resulting in drops in air pressure inside the ball. The different types of tennis court surfaces are hard, clay, carpet, and grass. Gravel got bounced on the least, 1 time . Watch the video of the dropping tennis ball. Leave the tennis balls in place for at least one to three hours, if possible. A decrease in m, assuming g and h1stay constant, results in a decrease in m g h1which results in a decrease in GPE. order to give a fair experiment. The colder, the lower the ball bounces, and vice versa. Some of the balls energy can be converted into heat. 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. 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.

We also use third-party cookies that help us analyze and understand how you use this website. Air resistance exists but does not affect the velocity of the ball significantly. The movement of the air causes the ball to bounce back off the . The felt helps to create spin on the ball when it is hit with a racket. Record the new pressure reading in your data table and repeat steps 4 and 5. Warm up the ball before it is used to increase its bounce. A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up. However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. This means it will be travelling the same speed when it hits the ground. were able to construct a successful experiment. Let the ball bounce until it stops, and then stop recording. Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. Most of the points on grass are very short. The harder the court surface is, the higher the rebounded ball will be. 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. half the results (concrete), we were incorrect about the basketball. This is impossible. What material makes a ball bounce higher? energy a surface absorbs, the more of it will remain for a ball to bounce. This was when the ball was falling in air. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? We could have improved this You can check the weather stats at. As gravity remains the same the amount of work acting on the ball remains the same (apart from slightly more air resistance due to the ball travelling faster and so hitting more air particles per second, but the effect of this is negligible) and the ball travels further before stopping. The bounce of a cold superball is shorter than that of a warm superball. Carpet2. This was added onto another issue we had to The Graph on page 23 shows that all of the results were very close together. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. Averages are more reliable than using one result as they take into account variation between results. 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 the ball hits the floor and stops, that energy has to go somewhere. Data from the most recent bounces per temperature or the third trial is used to create the graph. The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. . The higher the height from which the ball was dropped from, the higher the height to which it bounced. Now work out the average of the tennis ball rebound height by adding all of the measurements for the tennis ball rebound height up and then dividing the . If you are looking for a challenging sport, tennis is an excellent choice for the winter months. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. 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. Make a note of which one bounces up higher and how high they bounce! As the ball hits the blades of grass, they bend and don't provide as much upward rebound. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. A cold ball typically has less bounce than a warm ball. Once the drag force equals the gravitational force all forces are equal and acceleration stops.

Instead, as the ball is still always loosing GPE so long as it is still falling, all GPE is converted into thermal energy. 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. Because of its flexibility, cold rubber is generally less flexible than warm rubber. 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. This means that if a heavier ball is to be used then it will need to be dropped from higher to reach its terminal velocity. The balls leave the floor at the same speed with the same amount of KE and so both balls reach the same height and end up with the same amount of GPE at the top of their bounces. 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. 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. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. Therefore any change to the weight of the ball will affect the energy the ball has initially, which, as previously stated, affects the height to which the ball bounces. This therefore provides accurate and reliable results. Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. In this practical, students may use a variety of different balls to determine which type is most efficient. 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. Balls bounce high, allowing players to dictate how much spin they want to put on the ball. Therefore the results are valid. 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. 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. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. This would allow the actual coefficient to restitution to be calculated. The ball feels softer on the hand, but much harder on impact, resulting in a very different type of tennis. This is why it. Then when dropping the ball again eye level was kept level with the blue tack. The harder the court surface is, the higher the rebounded ball will be. 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. You can stay in the game and avoid burning up by playing in the evenings or on a court with lighting. Tiles3. 15 inches, and the golf ball bounced 26 inches. Air is pumped into the ball and causes it to bounce. Bending Plant Roots with Gravity Lesson Plan Introduction. chose balls and surfaces with different hardnesses, textures and compositions in Please enter a search term in the text box.
