Although we were correct about 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. They are typically softer, allowing them to give them a little more space and make them easier to hit. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. 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. Then when dropping the ball again eye level was kept level with the blue tack. This experiment requires a ball that will bounce and a meter stick or other measuring device. The average variation between results was 3cm. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. This cookie is set by GDPR Cookie Consent plugin. Bouncing is what makes playing with a ball so much fun. 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. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. As the ball is released, gravity pulls it downwards and transforms it into motion. From this I am able to determine that the experiment was very accurate. Now, take your video and watch it to gather your data. This will be a table tennis ball. The trip is going to be thoroughly enjoyable. It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Most experiments investigate the effect of an independent variable on a dependent variable. Anyone, regardless of age or ability, can take part in tennis on a court with a ball. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. was proven correct after our experiment. h1will start at 2m and then move down in intervals of 10cm to 10cm. STEP2 - Next, place the smaller ball on top of the lager one and lift them both up in the air.. STEP3 - Drop em'!. Carefully climb the ladder with the ball. This applies to a ball falling in a vacuum. As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. An average will then be taken. 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 tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . : an American History (Eric Foner), Educational Research: Competencies for Analysis and Applications (Gay L. R.; Mills Geoffrey E.; Airasian Peter W.), The Methodology of the Social Sciences (Max Weber), Biological Science (Freeman Scott; Quillin Kim; Allison Lizabeth), Campbell Biology (Jane B. Reece; Lisa A. Urry; Michael L. Cain; Steven A. Wasserman; Peter V. Minorsky), 4-3 Assignment Project Management Strategies. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. When printing this document, you may NOT modify it in any way. - Ping pong ball x 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 Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. Then when it bounces up, it returns to its original shape. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. This is because as the ball goes faster it passes through a greater volume of air each second. The bounce should be between 53 and 58 inches. Keep your balls warm in order to get the best bounce possible. But how does concrete . 15 inches, and the golf ball bounced 26 inches. - Basketball x For instance, you can use old balls for the second round of the experiment compared to new balls. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. Each can from the same manufacturer can be different. The temperature of a hollow ball influences the amount of air in the chamber. 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. 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. If the ball bounces up more than .5 meter then, it is more elastic. This can be explained by two factors. 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. Aim: to find out which surface bounces a ball the highest. 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. Abstract and Figures. will differ from the height that the ball would have reached had it been dropped in a vacuum. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. The energy goes into deforming the ball-- from its original round shape to a squashed shape. Use the pressure gauge to release some of the air pressure from the ball. Do you have specific questions about your science project? solid. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. Drop (do not throw) the ball from a carefully measured height using the meter stick. One of the hunks of information we found was Therefore the heavier the ball is, the faster its terminal velocity. 3. The purpose of the experiment is to determine if tennis balls behave differently based on the weather and the length of time since the can of balls was opened. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. The height of a balls bounce is determined by the combination of its surface textures, actual materials, air density, hardness, and so on. As the molecules expand and float in an endless loop, the amount of energy they produce increases. the higher it popped up into the air. 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. Warmer balls bounce better than cold ones. 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. Since To a wider range of results i.e. 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. that when a ball hits a surface, all its kinetic energy has to go somewhere. Record the new pressure reading in your data table and repeat steps 4 and 5. Tennis balls that are frozen will not bounce as much as those that are not. 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 . Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. quicker and on time before they dropped back down. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. All of the factors that could have affected the results that were uncontrollable could have produced variations between results. Overall, our experiment taught us that harder If you play in hot weather, your balls may bounce significantly more. As the temperature rises, the gas molecules in the tennis ball expand. Hard court tennis demands a lot from your joints! 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. Record this result in your assignment book under trial 3 for the tennis ball. As for catching the balls on time, we changed our hand positioning and In my science fair experiment, the golf ball overall was the ball that bounced the highest. What material makes a ball bounce higher? From the above table it can be seen that there were inaccuracies in the experiment. 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. Will the air pressure change the bounciness of a ball? As the ball has less KE and is travelling slower it becomes stationary faster at the top of its arc. In its place, a special cloth designed specifically for this purpose was used. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion For multiple bounces, it's just like dropping the ball again from a reduced height. 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. 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 . A glass ball will bounce higher than a rubber ball if it doesnt break. 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 higher h1, the faster the velocity that the ball reaches. The temperature of a tennis ball can affect its bounce height. 1 tennis ball 1 golf ball. 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. Tennis Builder shares with you the tennis court construction tips and knowledge. It will not bounce to high if it is heavy. - Pencil x You can stay in the game and avoid burning up by playing in the evenings or on a court with lighting. = The distance between the bottom of the ball at the top of its arc after bouncing and the ground. Why a ball bounces: The ball's energy is matched by the ground it hits. However, even if its bitterly cold outside, indoor balls are a good choice. 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. found that different surfaces absorb different amounts of energy, and the less This also proves the accuracy of the experiment. 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. Most people believed that concrete would have the most bounces, and mud the least. 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. Doherty, P., 1991. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. 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. When it is dropped, the air molecules will squish together and then spring apart. The reason balls bounce is quite advanced science. In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. This experiment would provide me with more results that are relevant to the experiment that I have already conducted. There are many other great ball projects in this fun book by Madeline P. Goodstein. Please enter a search term in the text box. Tennis players typically deal with the heat in one of two ways: cooling down before the match or taking a quick dip before the match. 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. 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. 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. 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 . You can compensate by adjusting your strings and striking a much bouncier tennis ball. 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. Not September 28, 2022 by George Jackson. EQUIPMENT: 1 metre ruler 1 table tennis ball. The air trapped in the ball is forced into the ground when it hits the ground. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. 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. results, one of the many being that the harder the surface the ball was bouncing on, The colder, the lower the ball bounces, and vice versa. h2= The distance between the bottom of the ball at the top of its arc after bouncing and the ground. carpet, tennis 57 cm 56 cm 61 cm 58 cm A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. Use the paint and a tape measure to make a series of lines on your roll of paper. Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. 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. Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. 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. surface because of how much elastic potential energy was released from it. As an Amazon Associate I earn from qualifying purchases.Privacy Policy | Affiliate Disclosure. half the results (concrete), we were incorrect about the basketball. surface bounces a ball the highest. These cookies ensure basic functionalities and security features of the website, anonymously. Results are presented for a tennis ball, a . Averages are more reliable than using one result as they take into account variation between results. The more particles per cubic meter, the more drag acting upon the ball. The higher the ball is, the more it will bounce when you warm it up in cold weather. 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. Let the ball bounce until it stops, and then stop recording. Air is pumped into the ball and causes it to bounce. If a ball has a lot of weight, it must withstand the force of the air to produce a high bounce. The drag force increases as the ball goes faster. This would provide evidence on how the height from which the ball is dropped from affects the height to which it bounces without air resistance. 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. 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. old and new tennis balls (different surface textures/ages). will start at 2m and then move down in intervals of 10cm to 10cm. You can also try using a hair dryer to heat the ball up. the initial bounce height is 1 m). Note whether the ball and surface showed more of an elastic or inelastic collision. Line up the top of the table tennis ball with the top of the metre ruler (i.e. This cookie is set by GDPR Cookie Consent plugin. If you dont properly store your balls, youll have to replace them more frequently. This means it will be travelling the same speed when it hits the ground. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. For the most part, the document is a case study in compulsive precision. There were some trends observed in our These cookies will be stored in your browser only with your consent. The energy that the ball hits the floor with is kinetic energy. Copyright 2002-2023 Science Buddies. This is correct unless the ball shows signs of reaching terminal velocity. This was when the ball was falling in air. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. 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. This cookie is set by GDPR Cookie Consent plugin. Now use your data table to plot points on the graph. GPE=Mass (kg) Gravitational Field Strength (N/Kg) Height (m). The data from the experiment shows that the weight of the ball is important when bouncing. I will drop the ball 3 After your partner starts recording, hold your arms out and drop the ball from the same height each time. are 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. A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. 2. Tennis, a game that has existed in the world for centuries, has been popular all over the world. order to give a fair experiment. Let the ball bounce until it stops, and then stop recording. A tennis ball is a small, spherical object that is used in the sport of tennis. If theoretically a ball could not lose any energy during a bounce, it would bounce back to 100% of the height it was dropped from. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. This causes thermal energy to be given off. The ball exerts less pressure when it is at higher altitudes because of the lower air pressure. 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 is because it is easiest as the figure read of the meter rule is the result. Once the drag force equals the gravitational force all forces are equal and acceleration stops. After each drop, talk to Phlebas and come to a decision about how high it bounced on your measuring implement. Science Buddies Staff. 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. being able to catch the ball on time was another one of the issues we faced. Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. If the drag is less the ball will fall faster and is less likely to reach its terminal velocity. This cookie is set by GDPR Cookie Consent plugin. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. 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. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. Balls bounce in ways that are affected by gravity. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. 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. For any other use, please contact Science Buddies. will 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. Conclusion: The amount of energy absorbed by the surface will affect the bounce of the ball. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. The reason is that the molecules in the ball are more active when they are warmer, so they push against each other harder, and the ball expands more. 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. 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. To determine how high a tennis ball will bounce when dropped from a . from the ball, therefore causing it to bounce higher than it normally would on dirt What do you think this means about your results? h1 = The distance between the bottom of the ball before it is dropped and the ground. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. Use the measuring tape to measure 150 cm off the ground. - tennis ball x This means that the faster that the ball travels the larger the force of air resistance upon it.
