Air resistance exists but does not affect the velocity of the ball significantly. For any other use, please contact Science Buddies. As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. It relates to how much energy balls have, what they are made of, how they change shape and where the energy they have goes. The children were oblivious to these . At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. 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 was added onto another issue we had to If you string your racket 2 pounds lower in the winter, it will bounce more. Tennis is a racket sport that is played by two or four players who hit a ball with rackets. How can you measure the height a ball bounces? The cookies is used to store the user consent for the cookies in the category "Necessary". We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. The strength of Nadals forehand is what makes him so good on clay. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. Do you have specific questions about your science project? This is impossible. The reliability of our experiment wasn't so strong. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. Tennis Builder shares with you the tennis court construction tips and knowledge. Make a note of which one bounces up higher and how high they bounce! Ball trial 1 trail 2 trial 3 average Because of this, a fully inflated ball may look deflated if the temperature drops quickly. The steel ball on an unvarnished pine wood floor may not bounce at all, but rather make a dent, and so what the floor is made out of makes quite a lot of difference. 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. All rights reserved. As the temperature rises, the gas molecules in the tennis ball expand. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. Keep a close eye on the ball, and instruct Phlebas to do the same. This is because the ball starts with more GPE. "Balls Bouncing Off of Surfaces.". A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. The trip is going to be thoroughly enjoyable. Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. would bounce the highest on a hard, smooth concrete surface because a rubber ball As there is more KE, more energy is converted into elastic potential energy, As there is more elastic potential energy, more energy is converted back into KE energy. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. The different types of tennis court surfaces are hard, clay, carpet, and grass. Hypothesis. The height of the ball at each bounce is then calculated. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. 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. To a wider range of results i.e. Measuring tape 3. Balls change shape during play. 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. It will not have enough force to bounce if it is lit. We then bounced the balls on the surfaces and, measured the heights. was blowing in, so that if the balls were blown away, they would come straight to 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. GPE=Mass (kg) Gravitational Field Strength (N/Kg) Height (m). Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. Bending Plant Roots with Gravity Lesson Plan Introduction. Obviously, a ball won't bounce as high on carpet. . - Basketball x Aim: to find out which surface bounces a ball the highest. Averages are more reliable than using one result as they take into account variation between results. Tennis balls bounce differently in the high altitude and at sea. Keep your balls warm in order to get the best bounce possible. 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. h1will start at 2m and then move down in intervals of 10cm to 10cm. For multiple bounces, it's just like dropping the ball again from a reduced height. Increased energy and movement results in a bounce. 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. 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. an incorrect and unreliable result. Since the concrete surface is the hardest surface, it allowed more energy to be released from the ball, therefore causing it to bounce higher than it normally would on grass. Its not just a game for the wealthy; its also a game for everyone. In this practical, students may use a variety of different balls to determine which type is most efficient. 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. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. Repeat steps 1-6 with the different balls. Once the drag force equals the gravitational force all forces are equal and acceleration stops. 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. 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 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. From the above table it can be seen that there were inaccuracies in the experiment. Watch the video of the dropping tennis ball. Does it slope up or down? will start at 2m and then move down in intervals of 10cm to 10cm. Please wait while we set up your subscription TurnItIn the anti-plagiarism experts are also used by: King's College London, Newcastle University, University of Bristol, University of Cambridge, WJEC, AQA, OCR and Edexcel, Business, Companies and Organisation, Activity, Height and Weight of Pupils and other Mayfield High School investigations, Lawrence Ferlinghetti: Two Scavengers in a Truck, Two Beautiful People in a Mercedes, Moniza Alvi: Presents from my Aunts in Pakistan, Changing Materials - The Earth and its Atmosphere, Fine Art, Design Studies, Art History, Crafts, European Languages, Literature and related subjects, Linguistics, Classics and related subjects, Structures, Objectives & External Influences, Global Interdependence & Economic Transition, Acquiring, Developing & Performance Skill, Sociological Differentiation & Stratification. Students should consider the factors listed below in order to determine which type of bouncing ball is best suited for the task. Chemistry: The Central Science (Theodore E. Brown; H. Eugene H LeMay; Bruce E. Bursten; Catherine Murphy; Patrick Woodward), Psychology (David G. Myers; C. Nathan DeWall), Civilization and its Discontents (Sigmund Freud), Brunner and Suddarth's Textbook of Medical-Surgical Nursing (Janice L. Hinkle; Kerry H. Cheever), Principles of Environmental Science (William P. Cunningham; Mary Ann Cunningham), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. 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. h2= The distance between the bottom of the ball at the top of its arc after bouncing and the ground. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. 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. Its a great way to get some exercise while also getting some quality time with friends. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. Introduction: The harder the court surface is, the higher the rebounded ball will be. 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. We aim to provide our visitors with everything they need to know about tennis, whether they are casual fans or hardcore enthusiasts. The impact duration was between 65 and 71 ms. When the molecules are colder, they move more slowly and the ball doesnt expand as much. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. hypothesis, we predicted that a rubber ball would bounce the highest on rough 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. The bounce of the ball is a major factor in the game of tennis. A similar length stick, marked in 5-10cm bands of colour. 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 a result, they move at a slower rate of speed with less energy. When the ball hits the floor and stops, that energy has to go somewhere. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. Kinetic energy and ball shape. The reason balls bounce is quite advanced science. Take a ball and place it on the 150 cm line and drop it. 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. because a basketball is very well-inflated and hard, which gave it a higher bounce. Taking an average of several results creates a measurement in the middle of the variation created by the experiment, which is the result that is closest to the height that would be recorded for the balls bounce if it were measured in an experiment that was totally accurate. This experiment requires a ball that will bounce and a meter stick or other measuring device. 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. Our team of volunteer scientists can help. Science Buddies: Pilobolus Spore Sac Launch. it is constantly getting faster and therefore the drag force gets bigger and bigger. The higher h1, the faster the velocity that the ball reaches. Why do balls bounce higher on different surfaces? Click the "Experiment" button to find out! 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. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. The ball shoots back up after being slowed down. 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. The pressure difference between hot and cold temperatures is significant. less air resistance. Then draw a line to connect the dots. The more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. This still took us time and we still couldn't catch the The steel snaps back more quickly when it hits the ground. "That's The Way The Ball Bounces," The Exploratorium Museum, San Francisco, CA. Which ball will bounce higher off a hard surface? More thermal energy is also produced. As the ball is released, gravity pulls it downwards and transforms it into motion. use four meter sticks and go right the way up to four meters. on different types of surfaces, then recorded the height of the bounce. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. Friday - 25/04/14 Air resistance exists but does not affect the velocity of the ball significantly. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. The results are shorter rallies and quicker points. Use the pressure gauge to release some of the air pressure from the ball. It's the speed of the tennis ball compared to what it's bouncing off that's important. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. Why Does One Tennis Shoe Pull Your Sock Down? 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 . In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. Since The more particles per cubic meter, the more drag acting upon the ball. Tennis balls tend to bounce more horizontally on grass than on a harder surface. 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. You also have the option to opt-out of these cookies. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. Best hard court players of all time concrete, in which we were incorrect. 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. Carpet2. Belowis the graph of h1against h2. surface bounces a ball the highest. discovered that there is a handful of information that would assist my partner and I Balls bounce differently on different axes. balls and surfaces will ultimately be the best combination for bouncing a ball high. METHOD: 1. As it did so the downward force was partially balanced out by the upwards force of drag, increasingly so the closer the ball got to its terminal velocity. The temperature of a tennis ball can affect its bounce height. This proves that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. The higher the ball goes, the more GPE it ends up with. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. For any other use, please contact Science Buddies. Find a clear space to work in. 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. Write your measurements down. From dropping the ball we can see how high the ball will bounce to after having a loss or gain of energydue to sound or movement of the ball as it hits a hard surface. Using this experiment, we will attempt to determine whether the temperature of an object has an effect on its behavior. What affects ball bounce? 1. The higher the height from which the ball was dropped from, the higher the height to which it bounced. The colder, the lower the ball bounces, and vice versa. The exact interval will be determined after the preliminary experiment, as will the number of heights that the ball will be dropped from. Prediction reasons for variable control: The height the ball is dropped from will affect the height the ball bounces to due to the energy chain the ball goes through as it is dropped and bounces up again. 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. It is a firm rectangular surface with a low net stretched across the centre. 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. 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. This causes thermal energy to be given off. 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. Discussion: 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. the initial bounce height is 1 m). Please enter a search term in the text box. On the cardboard, mark the starting point, the point where the marble strikes the wood, and a point along the marble's path as it rolls away from the wood. 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. Record the new pressure reading in your data table and repeat steps 4 and 5. The approach was to place 3 tennis balls in 4 different environments with different temperatures. 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. Although catching small balls was an issue, we solved it by getting our better troubles my partner and I had during our experiment along with the problems we By conducting our experiment, we learnt that well-inflated rubber balls bounce the When the temperature rises in one direction, bouncing abilities increase, whereas when the temperature falls in the other direction, they decrease. Bouncing is what makes playing with a ball so much fun. But opting out of some of these cookies may affect your browsing experience. is well-inflated and made of rubber which would give it more kinetic energy and Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. 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. Reproduction of material from this website without written permission is strictly prohibited. This is because it is easiest as the figure read of the meter rule is the result. highest on hard, smooth surfaces. The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. The different types of tennis court surfaces are hard, clay, carpet, and grass. The tennis balls bounce in different ways. We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. Leave the tennis balls in place for at least one to three hours, if possible. Why does Rafael Nadal do so well on the clay? 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. We This is why it. 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. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion At 3ft, the basketball bounced 20 inches, the tennis ball bounced. However, it was the basketball These both support my prediction and show that my prediction was correct. - Sticky tape - 1 roll. 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. Then when it bounces up, it returns to its original shape. Then when dropping the ball again eye level was kept level with the blue tack. The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. Cold balls tend to have a bouncier texture. 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. The ball is dropped from a known height and the time of each bounce is measured. 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. Will the air pressure change the bounciness of a ball? changing air density, temperature. As they are pushed about, the molecules in the ball collide with and rub across each other." Place the tape measurer against the edge of a wall using the bluetack 3. It should be on a smooth cement surface for optimal ball bouncing. Therefore the ball goes higher. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. 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. Also the mass of the ball affects the chances of the ball reaching its terminal velocity. Try bouncing different kinds of balls to test this question. Warmer balls bounce better than cold ones. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. Also it will affect its bouncing properties. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. Use the measuring tape to measure 150 cm off the ground. 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. Equipment/materials used: Grades: Preschool and K-2. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. from the ball, therefore causing it to bounce higher than it normally would on dirt This means that KE is the same for both balls when each ball hits the ground. 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. (2020, November 20). Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. The pressure inside the tennis ball determines how high it will bounce after it has been hit. 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. 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. 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. During the research fraction of the experiment, it was Aim: to find out which surface bounces a ball the highest. 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.
