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 |

What determines the rebound height of a bouncing ball?
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.
How long does it take for a bouncing ball to come to rest?
seconds. Read this again slowly: Even though the ball bounces infinitely often, it comes to rest after a little more than 11 seconds!
What is the acceleration of a bouncing ball?
On earth, this acceleration due to gravity is 9.8 m/s2 (g= 9.8 m/s2). This means, in essence, that for every second for falling, the ball’s velocity will accelerate by 9.8 m/s.
Does drop height affect bounce height?
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.
Does the drop height affect the bounce height of a ball?
What type of energy is bouncing a ball?
kinetic energy
When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. When it reaches Earth, it collides head-on with an incredibly massive object that is, from your perspective, at rest. The ball slows down, deforms temporarily and shoots back up.
What is the formula for finding total distance?
If a body with position function s (t) moves along a coordinate line without changing direction, we can calculate the total distance it travels from t = a to t = b. If the body changes direction one or more times during the trip, then we need to integrate the body’s speed |v (t)| to find the total distance traveled.
How to measure the bounce of a ball?
This experiment requires a ball that will bounce and a meter stick or other measuring device. Drop (do not throw) the ball from a carefully measured height using the meter stick. Measure from the bottom of the ball. Determine how high the ball rebounds on its first bounce. To be consistent, again measure to the bottom of the ball.
What does the height of a bounce mean?
For multiple bounces, it’s just like dropping the ball again from a reduced height. If the first height is h, the second will be f*h, the third f*f*h, the fourth f*f*f*h, and so on.
How tall should the first bounce of a tennis ball be?
So if f is 0.9, the first bounce will be 0.9 times as high, the second 0.81 times as high, the third 0.729 times as high (as the original height), and so on. Try it yourself! Does f depend on the height? (it shouldn’t much, but it might..) Try it for different balls! which type of ball bounces the most? which kind of ball bounces the most?
What do you need to do the bouncing ball experiment?
This experiment requires a ball that will bounce and a meter stick or other measuring device. Drop (do not throw) the ball from a carefully measured height using the meter stick. Measure from the bottom of the ball. Determine how high the ball rebounds on its first bounce.
