tennis ball bounce on different surfaces experiment

Therefore the energy that the ball hits the floor with = mh, The proportion of energy lost when ball hits the floor = The Coefficient to the restitution of the two objects (C, All of the energy that the ball leaves the floor with is converted back into GPE, If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h, can be found out by looking at a graph, the gradient, as a percentage of 1 gives the amount of energy conserved and therefore C. The clamp stand will be clamped down to the desk using a g-clamp to prevent it falling over and causing possible injuries. Carefully climb the ladder with the ball. This is a result of the Anyone, regardless of age or ability, can take part in tennis on a court with a ball. Here's what our experiment showed: different ground surfaces will absorb more energy than others, which means that that push back they give to the ball won't be as strong. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. How Much Do Air Jordan Tennis Shoes Cost? The results are shorter rallies and quicker points. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. They are typically softer, allowing them to give them a little more space and make them easier to hit. These cookies will be stored in your browser only with your consent. 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 energy a surface absorbs, the more of it will remain for a ball to bounce. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. were able to construct a successful experiment. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. This applies to a ball falling in a vacuum. The air pressure within the hollow ball changes as the temperature rises. The effect of surface on the bounce height of a tennis ball. Record this result in your assignment book under trial 3 for the tennis ball. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures. Acrylic-topped, this surface offers the most consistent ball bounce of all the outdoor tennis courts. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. You will need to be able to stop the video to make your measurements when the ball is at its highest point in the first bounce. Use the pencil and ruler to connect the incoming and outgoing trajectories of the marble to the point where the marble bounced off the wood. Keep releasing pressure and repeating the experiment until the ball no longer bounces. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. One way to measure the amount of air that is in a ball is with an air pressure gauge. Changes in air pressure could have affected results as could changes in temperature however changes in these two factors would have been small; air pressure would not have changed enough to affect the results in the hour period in which the experiment was conducted, and although the rooms temperature may have increased by a degree or two, due to body heat, over the course of the period temperature was not a major factor that affected the height to which the ball bounced and would not have significantly affected the results. the "bouncing balls" experiment. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. The drag force increases as the ball goes faster. use four meter sticks and go right the way up to four meters. half the results (concrete), we were incorrect about the basketball. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. 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! An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. The more energy absorbed by the surface, the less that remains in the ball for it to bounce. [accessed August 4, 2006]. To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. Concrete got bounced on the most, 5 times, and the highest, 55cm. 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 . Science Buddies: Pilobolus Spore Sac Launch. 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. didn't catch the ball on time before it went back down to the ground, we would get Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. This will hopefully discount any anomalies automatically and leave us with three accurate and reliable results. A cold ball typically has less bounce than a warm ball. What was the outcome? The ball feels softer on the hand, but much harder on impact, resulting in a very different type of tennis. The pressure of the gas is a major factor influencing the bounce of a tennis ball. 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 changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. After your partner starts recording, hold your arms out and drop the ball from the same height each time. Materials 1. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. h1 = The distance between the bottom of the ball before it is dropped and the ground. As the temperature rises, the gas molecules in the tennis ball expand. However, you may visit "Cookie Settings" to provide a controlled consent. H is the height of the ball before it is dropped. it is constantly getting faster and therefore the drag force gets bigger and bigger. We The balls finish up with the same amount of energy and the only energy given out is thermal energy. - Measuring tape x Place the tape measurer against the edge of a wall using the bluetack 3. We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. an incorrect and unreliable result. The coefficient to restitution can be found out from a graph of, it follows the gradient of the graph change in h. . Try comparing two days with different atmospheric pressure. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. As the ball falls it hits against air particles. Now, take your video and watch it to gather your data. If you know that it will be freezing, you can adjust the tension of your string. The more particles per cubic meter, the more drag acting upon the ball. Equipment/materials used: This was added onto another issue we had to We could have improved this For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. I think this is Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. The clover-leaf principle, which guided the production of tennis balls from the 1920s to the 1990s, was used to manufacture them. 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. 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. METHOD: 1. Measuring tape 3. Do five drops on your first surface. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. There is a chance that you will bounce. A cold ball will bounce farther than a warm one. Why do golf balls bounce so high on concrete? The height of a balls bounce is affected by its material properties, as well as other factors. 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. small balls sometimes, but we could have improved this by taking many attempts 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. It is important to let the ball fall out of your hands, and not to push it down with your hands, wrists, or arms. Although we were correct about A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. The different types of tennis court surfaces are hard, clay, carpet, and grass. Experiment 2 is for testing the effect of air pressure. To be consistent, again measure to the bottom of the ball. Although catching small balls was an issue, we solved it by getting our better Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. We did this by bouncing different types of balls Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. The results of the experiment were obtained with a method that ensured that every drop was under similar conditions which ensured a fair test. 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. less air resistance. According to our background research, a When it is dropped, the air molecules will squish together and then spring apart. 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. Balls change shape during play. Once the drag force equals the gravitational force all forces are equal and acceleration stops. Also it will affect its bouncing properties. The material ball is made from will affect the ball as if it is smooth then the drag will be significantly less than if it is rough. 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. What factors affect the bounce height of a ball? 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. Science Buddies Staff. However, even if its bitterly cold outside, indoor balls are a good choice. old and new tennis balls (different surface textures/ages). The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. Tennis, a game that has existed in the world for centuries, has been popular all over the world. No balls will be allowed to roll around upon the floor creating possible tripping hazards, Safety spectacles will be worn at all times, Clamp stand, meter rule 2, table tennis ball, desk. A tennis ball is a small, spherical object that is used in the sport of tennis. 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. Then they would be dropped from a table, and the height would be measured. "Under Pressure: Ball Bouncing Dynamics.". Use a uniform surface to drop the ball onto. 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. 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. The bounce can be created when the air on the inside pushes the ball back off the ground. were able to construct a successful experiment. It will be vinyl tiling. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. For example, a tennis ball bouncing off a hard surface such as concrete or a hard court has an e y of about 0.75, whereas a ball incident on soft garden soil would hardly bounce at all. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. 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. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. How does the material of a ball affect its bounce? 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. The temperature of the tennis ball has an impact on its bounce. Which ball will bounce higher off a hard surface? Air resistance exists but does not affect the velocity of the ball significantly. As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. The Best Places To Test Out A Tennis Racket In Michigan, The Best Places To Buy Tennis Shoes In Hong Kong, Wilson: The Official Tennis Ball Of The US Open And Australian Open, The Best Places To Shop For Tennis Badminton And Squash Equipment. 2. Then when it bounces up, it returns to its original shape. Therefore, harder surfaces will ultimately bounce a ball higher. When printing this document, you may NOT modify it in any way. It should be on a smooth cement surface for optimal ball bouncing. 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. The bounce of a cold superball is shorter than that of a warm superball. 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. Line up the top of the table tennis ball with the top of the metre ruler (i.e. This will be called the average of the middle three repeats. Now use your data table to plot points on the graph. The experiment was conducted as the method (below) states. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. . This is impossible. 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 h. Do a larger amount of results; 1cm, 2cm, 3cm, 4cm etc. Science Buddies Staff. 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. The ball gains energy of motion, known as kinetic energy. results, one of the many being that the harder the surface the ball was bouncing on, A lot of 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. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. 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. Does a tennis ball bounce differently on different surfaces? Here's what you need to do this experiment: Bouncy Balls - a least 6 identical balls; A measuring cup or mug for heating water in the microwave; Access to a freezer . There is an activity at home that can be used to investigatebounciness. 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. Best hard court players of all time The data from the experiment shows that the weight of the ball is important when bouncing. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. As an example, on the day we performed our experiment, a strong wind was This is due to two factors. Tennis balls are different at sea level and at high altitudes. Not This can be explained by two factors. solid. 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. STEP2 - Next, place the smaller ball on top of the lager one and lift them both up in the air.. STEP3 - Drop em'!. Necessary cookies are absolutely essential for the website to function properly. 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. Please enter a search term in the text box. - Ping pong ball x When the molecules are colder, they move more slowly and the ball doesnt expand as much. In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. This is why you should have seen that when you bounced the basketball on a relatively hard surface it bounced higher (it lost less energy) compared with when it was bounced on a softer surface . is well-inflated and made of rubber which would give it more kinetic energy and The ball is dropped from a known height and the time of each bounce is measured. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. Friday - 25/04/14 . Balls bounce in ways that are affected by gravity. Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. An investigation into how they impact play on the court. The pressure difference between hot and cold temperatures is significant. This cookie is set by GDPR Cookie Consent plugin. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. But how does concrete . You also have the option to opt-out of these cookies. Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . 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. 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. Push it against the measuring tape, careful to keep it at the same height. However, it was the basketball Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). To determine how high a tennis ball will bounce when dropped from a . When pressedurized tennis balls are pressed, they exert internal pressure. 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. There were some trends observed in our As the molecules expand and float in an endless loop, the amount of energy they produce increases. Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Why do balls bounce higher on different surfaces? The tennis balls bounce in different ways. (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. How can you measure the height a ball bounces? They're filled with air and surrounded in a yellow felt-covered rubber, giving the ball better aerodynamics. The ball did not appear to reach its terminal velocity which also supports my prediction. - Pencil x In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. All rights reserved. Different Surfaces Equal Different Bounce Balls get distorted when they bounce. Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. Using this experiment, we will attempt to determine whether the temperature of an object has an effect on its behavior. Although we had all these challenges, 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. Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. The variation between results was obtained by taking the minimum result away from the maximum result. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. discovered that there is a handful of information that would assist my partner and I Why does Rafael Nadal do so well on the clay? 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. When it hits the ground, the bottom of the ball becomes flat against the floor. The Physics of Grass, Clay, and Cement. Make a note of which one bounces up higher and how high they bounce! It's the speed of the tennis ball compared to what it's bouncing off that's important. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. 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. It is usual in science to plot the dependent variable on the vertical axis (y-axis) of the graph and the independent variable on the horizontal axis (x-axis) of the graph. Different courts are better suited to each players style. As the ball falls to the surface it has kinetic energy. Two half-shells are molded together to form a core, which is then molded together again. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. Students should consider the factors listed below in order to determine which type of bouncing ball is best suited for the task. Tennis balls are more likely to bounce on grass.

Bending Plant Roots with Gravity Lesson Plan Introduction. Kinetic energy and ball shape. A tennis court is the venue where the sport of tennis is played. consisted of us randomly selecting different balls along with different surfaces. It relates to how much energy balls have, what they are made of, how they change shape and where the energy they have goes. 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. Fully pump up the basketball and check the pressure with the pressure gauge. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. Therefore, 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 was dropped from the higher heights the ball began to show signs of reaching its terminal velocity before it reaches the ground. Aim: to find out which surface bounces a ball the highest. catcher to catch the balls. present. By conducting our experiment, we learnt that well-inflated rubber balls bounce the This still took us time and we still couldn't catch the 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 tennis balls bounce in different ways. - Paper x Do different kinds of balls bounce differently? 1. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. If we It will not bounce to high if it is heavy. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. 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. 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. Air resistance exists but does not affect the velocity of the ball significantly. that bounced the highest on the 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. Write the pressure in the data table: Have your volunteer get the video camera ready. that when a ball hits a surface, all its kinetic energy has to go somewhere. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. 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. The Graph on page 23 shows that all of the results were very close together. You can check the weather stats at. 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. This is why it. Keep a close eye on the ball, and instruct Phlebas to do the same. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower.
