How do you measure bouncing?
Put your first ball back, and now get a second, different ball.” For each ball, each group will have three trials, or three numbers of inches that the ball bounced up. Estimate the median value or calculate the average value by adding all three numbers, and dividing by three.
What equipment do they use to measure how high the ball bounces?
The Vertical Ball Rebound Tester is used for the analysis of the ball rebound properties of a sports surface. The device drops a ball from a certain height, after which the ball bounces again.
How do you calculate a bouncing ball?
200 represents the initial height, and (2, 111) represents the second height after the first bounce at 111 cm. We now know that this ball has a 55.5\% rebound ratio. We can fill in a table or calculate the height of the ball after each further bounce….Student Exploration.
| 1 | 200 |
|---|---|
| 2 | 111 |
| 3 | 61.605 |
| 4 | 34.190775 |
| 5 | 18.97588013 |
What determines the rebound height of a bouncing ball?
This energy lost in the bounce is a more or less constant fraction of the energy of the ball before the bounce. As the ball goes back up, kinetic energy (now a bit less) gets traded back for gravitational potential energy, and it will rise back to a height that is the original height times (1-fraction of energy lost).
What surface makes a ball bounce higher?
As the ball is released, gravity pulls the ball downwards and transforms that potential energy into kinetic energy, the energy of motion. The harder the court surface is the more energy a dropped ball retains and the higher it rebounds. A basketball bounces pretty well on hardwood, but even better on concrete.
What is the height of a bouncy ball?
Height balls bounced: soccer ball: 62 cm. tennis ball: 41 cm. exercise ball: 65 cm.
How do you calculate bounce efficiency?
The bounce efficiency was calculated by dividing the bounce height by the drop height. Explain why this difference in heights can be used to calculate the energy efficiency of each ball.
Does the height of a tennis ball drop affect the height of the bounce?
If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.
How Does height affect the bounce of a ball?
A: The height to which a ball will bounce depends on the height from which it is dropped, what the ball is made out of (and if it is inflated, what the pressure is), and what the surface it bounces from is made out of. A ball’s gravitational potential energy is proportional to its height.
