tennis ball bounce height experiment

Bouncing Ball Experiment Our simple experiment is to drop a ping pong ball weighed at 3 grams from a height of 1 metre then 90cm, 80cm, 70cm, 60cm, 50cm, 40cm and of course zero cm. That means your ball isn't legal. After it was dropped, how many times was the ball at a height of 2 feet? Both balls ... Why would a well-used tennis ball not bounce ... you can use a camera to film the experiment. My aim of this investigation is to find out the efficiency of a golf ball, netball, ping pong ball, rubber ball, tennis ball and a baseball on their first bounce from a Procedure: Drop each ball from heights of 40, 80, and 120 cm. To measure the bounciness of a ball, you can try dropping it from a height onto a hard surface. Step 3: Drop two balls (one at a time) and record the height that they bounced after hitting the floor. Bouncing Ball Experiment . This experiment can also be done with three balls, a basketball, a tennis ball and a Ping-Pong ball. I will briefly describe what it is: The machine is configured to serve the ball at a fixed speed to the center of the left (or right) service court Based on the rotation in 3 directions (X,Y,Z) of the ball, the machine would let the ~ Tennis serving machine--- How does a spinning ball bounce? The graph above represents the relationship between the time elapsed after the ball was dropped and the height of the ball above the ground. Record the results by measuring the distance from the ground to the paint on the butcher paper. BACKGROUND: TABLE TENNIS The official rules of table tennis specify the characteristics and properties of a ping-pong ball: ‘The ball shall be spherical, with a diameter of 38mm. There is a experiment very similar to mine. Repeat the steps for each surface. The relationship will be determined by altering the initial height of the ball prior to the release in order for the ball to bounce. Use the following diagram as a basic guide to help get you started. The standard bounce required shall be not less than 23.5cm nor more than 25.5cm when dropped from a height of 30.5cm Drop ball and mark where the lowest part of the ball is after the first bounce. The ball undergoes some rather significant and nonlinear distortions during the bounce. The ball used in this experiment would be a tennis ball, and it will be dropped on the same surface each experiment. 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 One problem; the linear relation between drop height and rebound height doesn't work if the height … C drop the bigger ball from a greater height. Controlled Variables- Surface, tape measure, same person drops the ball, same person measures the height, positioning of tape measure. Give each group a golf ball, tennis ball and rubber ball. In the experiment, "Bounce Height vs. Drop Height", we determined the bounce coefficients of a tennis ball, ping pong ball, and a golf ball. The procedure also involved observing how the height from which a ball is dropped affects its bounce. A ball's gravitational potential energy is proportional to its height. 1. In this case the bounce height of the tennis ball depends on the height from which it is dropped. Each can from the same manufacturer can be different. In fact, Rule 3 of the Rules of Tennis (2) states that when a tennis ball is dropped from a height of 100 inches (254.00 cm.) 2. After analyzing all 30 videos in LoggerPro, I was able to find the height of the first bounce of the tennis ball. Pick one of the balls and ask students to brainstorm some ways to make the ball bounce higher (Increase the force with which you bounce the ball to the ground, raise the height from which the ball is thrown, add more air to balls such as basketballs, into which air can be pumped, etc.) The ping pong ball seemed to be in second place, and the tennis ball was in third place. Just so, will a ball bounce higher if it is dropped from a greater height? Use the ball that your players are most comfortable with. You've probably noticed that if you drop even the bounciest of tennis balls from a height, it never bounces back higher than where it started. When you drop the ball, gravity pulls it down and it picks up speed. Hold a ball so its lowest point is at the 1 metre point. B drop both the balls from the same height. Tennis balls bounce about 53% of their dropped height, Super Balls about 85 or 90 % of their dropped height. Get the students to develop a fair test to compare the height of bounce for each ball, using the first measuring stick/ruler. Drop (do not throw) the ball from a carefully measured height using the meter stick. The procedure also involved observing how the height from which a ball is dropped affects its bounce. You've probably noticed that if you drop even the bounciest of tennis balls from a height, it never bounces back higher than where it started. You can also change how a ball bounces by changing its temperature. Annie and Giuliana's science fair experiment tests the hypothesis that warmer tennis balls will bounce higher than frozen ones. In this case, both drop height and bounce height will be measured. 3) The height of the first bounce of each drop was recorded on the wall behind them with a piece of chalk, and a measuring tape was then used to find the height of each of the bounces from the chalk marks. Identify the independent variable. If don't, however, something is wrong. Tennis balls begin to lose their bounce as soon as the tennis ball can is opened. Results are presented for a tennis ball, a baseball, a golf ball, a The differences in bounce height depend on the style of construction as well as the material the balls are made of. To measure the bounciness of a ball, you can try dropping it from a height onto a hard surface. Q. The ITF drop test is performed from a height of 100 inches, which results in a drop speed of 16 mph and an energy at impact of about 0.083 Joules (J). By Crawford Lindsey. The 'two-ball bounce problem' is often used to demonstrate that the rigorous rules of physics can produce counter-intuitive effects. They devise a way to measure the bounce of a ball. Effect of Pressure in Ball Bounce Height Physics Kids Projects, Physics Science Fair Project, Pyhsical Science, Astrology, Planets Solar Experiments for Kids and also Organics Physics Science ideas for CBSE, ICSE, GCSE, Middleschool, Elementary School for 5th, 6th, 7th, 8th, 9th and High School Students. 14,250. Weight is necessary because this will be the main fact in calculating joules from velocity. Listen carefully to the distinct sounds of each ball as it bounces. The sweet spot for our experiment ended up. As part of an experiment, a ball was dropped and allowed to bounce repeatedly off the ground until it came to rest. Q. What happens when you drop a perfectly balanced stack of balls? Students will be able to feel the … The experiment will show if temperature affects the height of a bouncing tennis ball. However, by far the most important reason is that collisions are not elastic. Physics: I have an idea of making a tennis serving machine. I will be comparing the results from testing varying amounts of internal pressure for the largest ball and their corresponding maximum heights of the smallest ball to see if there is any relation. Figure 4 shows that the tennis ball only reaches 3 meters. Abstract: In the experiment, "Bounce Height vs. Drop Height", we determined the bounce coefficients of a tennis ball, ping pong ball, and a golf ball. 2. A ball hitting the ground with greater speed should bounce higher than a ball striking the ground with less speed; therefore, a ball dropped from a greater height will bounce higher than a ball dropped from a lesser height.When a ball is bouncing high into the air, it will continue to bounce for some time. Dependent Variable: The Bounce (How height is the ball going to Bounce) because of the difference in pressurization. It’s best if the person recording the height is sitting on the floor for the most accurate perspective. This scientific mystery can be demonstrated at home or school with a simple experiment. 4. Make sure you line up the centre of the balls so that the tennis ball is exactly on top of the basketball. From the experiment, once the tennis ball was dropped, potential energy transformed into kinetic and once the ball bounced on the concrete surface the energy again transformed into elastic potential energy once the ball was squashed and then back to kinetic energy to a certain height lower than the initial meaning some energy was lost to heat and sound of the tennis ball. A) One B) Two C) Three D) Four Tell the students that today you are going to investigate two of the variables that affect how high a ball bounces: the material the ball is made of and the height that it is dropped. The uncertainty of the average bounce height is the range of the bounce heights (high-low) divided by 2. Baseballs have less bounce than tennis balls or golf balls. One ball will be kept at room temperature for a control. Have them list all the variables they think will affect ball bounce. A Bouncing Ball Experiment. Hypothesis: The return height percentage is constant for all drop heights up to the 4th floor (11.97 meters) because the efficiency is always the same, therefore, if the drop height is higher, the bounce height will also be higher. The marble will bounce the least high. Since 3/4 is equal to 75%, then one can conclude that the bounce height is about 75% of the dropped height. Your ball is a bit too lossy, so it's possible that what you measured is correct (for that ball). Bouncing Ball Experiment . Place one of the tennis balls in the freezer for 20 mins. Then the basketball collides with the tennis ball and projects the tennis ball toward the ceiling. Modern regulation tennis balls are kept under pressure (approximately two atmospheres) until initially used; balls intended for use at high altitudes have a lower initial pressure, and inexpensive practice balls are made without internal pressurization. Taking into account the effects of air resistance, the Understanding how the ball bounces can help you and your students pick and read shots. Balls bounce differently on different axes. This experiment requires a ball that will bounce and a meter stick or other measuring device. The higher air pressure will increase the height of the bounce because the ball will have more force coming off of the ground. Divide your students into groups of 4-5 students each. Our investigation began with a question. Results: On average, the rubber bouncy ball will bounce the highest, followed by the ping pong ball. Set a timer, and let them ―experiment‖ with the bouncing of each ball for one minute. Balls become softer with use. Step 3: Drop two balls (one at a time) and record the height that they bounced after hitting the floor. Leave these taped up through Question 8 of this activity. Planning the experiment . C. I am basing this hypothesis on the equation mentioned above that states, p=rRT,” where “p” is the pressure, “r” is the density, “R” is a constant specific to the gas and “T” is temperature” (Sheehan,2018). Record the height on the chart. Then do exactly the same with the basketball. The durability test involved firing each ball 30 times at high speed and oblique angle onto a cutout slab of hardcourt. The tennis ball was then dropped from various heights; 1, 1.5 and 2 meters above a hard surface, using a meter ruler, before it was dropped onto the ground and the resulting bounce height measured. Repeat 6 times to obtain 6 marks. Each bounce should be to the same height. >I used to play Lawn Tennis so i was curious to why certain balls where chosen. The factor that will be investigated in this experiment would be the initial height of the ball. onto a hard (concrete) surface it must bounce to a height between 53 inches (134.62 cm.) This means that, ignoring the effects of air resistance, a regulation tennis ball would have a COR of between 0.728 and 0.759. Of course, it’s impossible to get it 100% exact, but you’ll be able to get a good estimate of how high the ball … A legal tennis ball has to have a 138 to 151 cm rebound from a hard surface when dropped from a height of 254 cm under carefully controlled lab conditions. The ball used in this experiment would be a tennis ball, and it will be dropped on the same surface each experiment. Baseballs have less bounce than tennis balls or golf balls. Write down the height (37 inches) In this order, I will be able to state which ball can bounce the highest out of a baseball, football, basketball, and tennis ball. Therefore the trend is only valid for the range 0 to 1. A drop each ball onto different surfaces. As players grow and/or their ability improves, try using a ball that bounces a bit higher. Today I’m going to keep talking about that single bounce. - Type of surface the tennis ball is dropped on Dependent: - Height at which the tennis ball bounces Controlled: - Same ball - Height at which the ball is dropped - Amount of force applied - Person dropping the ball Part way. ). You can also change how a ball bounces by changing its temperature. Carpet, stone, grass etc) Students may measure the height of the first bounce or count the amount of times the ball bounces in total when dropped from a specific height. Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. These results were recorded alongside the temperature of the balls. My hypothesis: With an increase in temperature, the tennis ball will bounce higher than that of a ball that experiences decreased temperatures. playing conditions. Factors to consider when devising an experiment: controlling as many variables as possible, for example, the height from which the ball is dropped and dropping the ball … Measure (and write down) the average of the 6 tests, and also the range. The relationship will be determined by altering the initial height of the ball prior to the release in order for the ball to bounce. They can be tested to determine their bounce. Have each group set up a testing station and follow the directions on their ―Height of Rebound‖ work-sheet. It might seem like this is a physics cheat to have the tennis ball bounce so much higher than it started (and that's probably why it's so cool to see it). The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. the ball bounces back to the drop height) and the minimum being no elasticity (i.e. The usual explanation involves two steps. Recently, our class completed a bouncing-ball experiment. But in terms of energy, it's all legitimate. The ball is key, the coefficient of restitution is the kinetic energy the ball will exert given the height and weight of the ball and what the ball is made of. Measure from the bottom of the ball. (Left) The system at rest at the initial drop height. That means your ball isn't legal. Our original hypothesis of the sweet spot experiment was that the tennis ball would bounce the highest in the middle of the racket.
