tennis ball bounce on different surfaces experiment

The colder, the lower the ball bounces, and vice versa. As velocity increases air resistance increases in proportion to the square of the velocity. - Four surfaces (carpet, rough concrete, dirt and smooth concrete). Although we were correct about The drag force increases as the ball goes faster. Write each measurement in the data table. We did this by bouncing different types of balls As the ball hits the blades of grass, they bend and don't provide as much upward rebound. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. METHOD: 1. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. Carpet2. 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 As energy cannot be created or destroyed it follows that the energy must have come from the energy that the ball possesses. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. Most experiments investigate the effect of an independent variable on a dependent variable. Concrete4. This experiment requires a ball that will bounce and a meter stick or other measuring device. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. Also the ball flattening upon impact doesnt have to be taken into account whereas if one was measuring from the top of the ball as it hits the floor to the top of the ball before dropping it or at the top of its arc after bouncing or the middle of the ball as it hits the ground to the middle of the ball before dropping it or the middle of the ball at the top of its bounce then the fact that the ball flattens momentarily on impact with the floor would have to be taken into account. This blew the light balls away, giving us an unvalid result or catch. Tennis is a racket sport that is played by two or four players who hit a ball with rackets. If the ball bounces up more than .5 meter then, it is more elastic. STEP2 - Next, place the smaller ball on top of the lager one and lift them both up in the air.. STEP3 - Drop em'!. 3. faced. Copyright 2002-2023 Science Buddies. Use a uniform surface to drop the ball onto. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. Our team of volunteer scientists can help. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. Balls bounce in ways that are affected by gravity. Please enter a search term in the text box. If the mass of the ball is heavier the weight is heavier (weight = mg) and downward force acting upon the ball is greater as well. Science Buddies Staff. This is impossible. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. This is because as the ball goes faster it passes through a greater volume of air each second. - Rubber ball x Use the paint and a tape measure to make a series of lines on your roll of paper. As a result, the ball is lifted in this manner. Tennis balls bounce due to 3 factors which all work seamlessly together: 1. 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. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. When a ball drops in air there is air resistance to which the ball loses energy in the form of thermal energy. Method: 1. I will drop the ball 3 Ball trial 1 trail 2 trial 3 average What material makes a ball bounce higher? We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. If it bounces up less than .5 meter, then it is more inelastic. Focus. The higher the height from which the ball was dropped from, the higher the height to which it bounced. The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. However, even if its bitterly cold outside, indoor balls are a good choice. half the results (concrete), we were incorrect about the basketball. 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. The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. will start at 2m and then move down in intervals of 10cm to 10cm. Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. It would also be fun to explore the effect of different surfaces on the bounce of the bouncy ball. Now use your data table to plot points on the graph. Why does a tennis ball bounce higher on concrete? Analytical cookies are used to understand how visitors interact with the website. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. an incorrect and unreliable result. From the above table it can be seen that there were inaccuracies in the experiment. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. I plan to collect at least ten results as this will make the conclusion and graph I am able to draw from the experiment more accurate than if I had less results than ten. 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. This applies to a ball falling in a vacuum. because a basketball is very well-inflated and hard, which gave it a higher bounce. C. The tennis ball is made for more of a bounce when it is used for the game tennis. Air resistance exists but does not affect the velocity of the ball significantly. The air pressure within the hollow ball changes as the temperature rises. : 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. Acrylic-topped, this surface offers the most consistent ball bounce of all the outdoor tennis courts. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. The higher h1, the faster the velocity that the ball reaches. Therefore the height the ball bounces will be proportional to the height that the ball is dropped from up to a certain point, where the ball begins to show signs of reaching its terminal velocity before it reaches the ground. Its not just a game for the wealthy; its also a game for everyone. They are typically softer, allowing them to give them a little more space and make them easier to hit. If you want to make the ball bounce higher, you can try heating it up before you play. 70% is retained. Then when dropping the ball again eye level was kept level with the blue tack. 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. 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. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. 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. It does not store any personal data. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. 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. In our The harder the court surface is, the higher the rebounded ball will be. Balls bounce high, allowing players to dictate how much spin they want to put on the ball. h2= The distance between the bottom of the ball at the top of its arc after bouncing and the ground. Results are presented for a tennis ball, a . - Pencil x The tennis balls bounce in different ways. discovered that there is a handful of information that would assist my partner and I Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. This can be explained by two factors. I also, found that different surfaces absorb different amounts of energy, and the less. This is because the higher the starting height of the ball, the higher the ball's potential energy. harder surfaces will ultimately bounce a ball higher. This means that KE is the same for both balls when each ball hits the ground. Note whether the ball and surface showed more of an elastic or inelastic collision. Then draw a line to connect the dots. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. Repeat the process three times with the same ball and record results. This is due to two factors. Therefore the coefficient to restitution = 0.7. Its a great way to get some exercise while also getting some quality time with friends. 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. Therefore the height that it reaches is less high. For instance, you can use old balls for the second round of the experiment compared to new balls. We then bounced the balls on the surfaces and 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. small balls sometimes, but we could have improved this by taking many attempts Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. Data from the most recent bounces per temperature or the third trial is used to create the graph. 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. From this it can be seen that using the average of the middle three results is more accurate than using the average of all five, as it automatically discounts most anomalies. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. There were some trends observed in our results, one of the many being that the harder the surface the ball was bouncing on, his the height of the balls bounce. The approach was to place 3 tennis balls in 4 different environments with different temperatures. Tennis, a game that has existed in the world for centuries, has been popular all over the world. rubber ball would bounce the highest on concrete. was proven correct after our experiment.
