If we Science Buddies Staff. Equipment/materials used: rubber ball 39 cm 38 cm 41 cm 39 cm. his the height of the balls bounce. When the ball hits the floor and stops, that energy has to go somewhere. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. Since Therefore, our hypothesis was refuted by our final results. Bending Plant Roots with Gravity Lesson Plan Introduction. It does not store any personal data. When the ball is pulled toward the ground, gravity slows it down so that it doesn't bounce as many times. In the heat, the molecules are more active, so the ball can bounce higher . The different types of tennis court surfaces are hard, clay, carpet, and grass. 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. Place the tape measurer against the edge of a wall using the bluetack 3. Focus. Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. it goes back into the ball, giving it more force to pop back up into the air. A decrease in bounce is caused by a colder temperature. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes.

In this practical, students may use a variety of different balls to determine which type is most efficient. Analytical cookies are used to understand how visitors interact with the website. Its not just a game for the wealthy; its also a game for everyone. If the ball bounces up more than .5 meter then, it is more elastic. 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. The higher the ball goes, the more GPE it ends up with. 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. From this I am able to determine that the experiment was very accurate. What factors affect the bounce height of a ball? Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. 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. This cookie is set by GDPR Cookie Consent plugin. A tennis ball is made of rubber and is covered with felt. 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. carpet, tennis 57 cm 56 cm 61 cm 58 cm Parallax error will be avoided by dropping the ball one time that will not be measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. High bounce ball 2. Once the ball hits the ground, its displacement is momentarily zero. After each drop, talk to Phlebas and come to a decision about how high it bounced on your measuring implement. Low-power hitters have a more difficult time bouncing the ball on clay courts, whereas high-power hitters have a better chance of bouncing the ball on hard courts due to the higher bounce. Balls bounce differently on different axes. Method: 1. Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. The trip is going to be thoroughly enjoyable. I will drop the ball 3 Repeat the process three times with the same ball and record results. The harder the court surface is, the higher the rebounded ball will be. Measure from the bottom of the ball. 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. In air considerations have to be taken into account such as air resistance but even so the rough height to which it will bounce to can be predicted before dropping the ball. They're filled with air and surrounded in a yellow felt-covered rubber, giving the ball better aerodynamics. The longer it takes to stop, the higher it bounces to.

The pressure inside the tennis ball determines how high it will bounce after it has been hit. Aim: to find out which surface bounces a ball the highest. Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) , v is greater therefore KE is greater by a larger amount). Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. 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 . The balls bounced higher on the concrete Not only does a ball distort its shape--so does the surface on which the ball bounces. For any other use, please contact Science Buddies. Click the "Experiment" button to find out! Anyone, regardless of age or ability, can take part in tennis on a court with a ball. The balls dropped from 75 centimeters will bounce higher than those dropped from 50 centimeters, and the balls in the 50 centimeter trials will bounce higher than those in the 25 centimeter trials. Two different types of balls, Penn Championship and Non-Championship will be compared. This is due to two factors. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). Does it slope up or down? We did this by bouncing different types of balls The maximum and minimum results were included when working out the variation between results however, seeing as the maximum and minimum results were produced by the experiment and are therefore part of the variation between results produced by the experiment. There is an activity at home that can be used to investigatebounciness. was proven correct after our experiment. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. Balls are not round. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Air resistance exists but does not affect the velocity of the ball significantly. = The distance between the bottom of the ball before it is dropped and the ground. It will not have enough force to bounce if it is lit. from the ball, therefore causing it to bounce higher than it normally would on dirt The changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. (2020, January 12). hard ball made of rubber should bounce the highest on a concrete surface, which The higher h1, the faster the velocity that the ball reaches. - Basketball x One of the hunks of information we found was Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. Concrete will help bounce a ball the highest as it's hard and First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. Internal air pressure is critical to the bounce of most tennis balls. 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 bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. The surface onto which the ball is dropped upon will be kept the same. As in both cases the main form of energy is GPE it follows that the higher the ball is dropped from, the higher the ball will bounce. For a falling object the Coefficient to restitution (C, ) is equal to the velocity squared as the object is travelling at as it leaves the floor (v, ) divided by the velocity squared as it hits the floor (v, If a ball is dropped in a vacuum. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. As the ball falls it hits against air particles. 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. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. The impact duration was between 65 and 71 ms. Height will be the variable that we will vary. The reliability of our experiment wasn't so strong. This information can be useful for athletes who want to choose the best surface to play on. the higher it popped up into the air. 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 more KE that the ball possessed as it hit the floor, the more that was transferred into elastic potential energy and back into KE.

A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. 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.
