# How does the height a ball is dropped from effect the rebound height?

How does the height a ball is dropped from effect the rebound height?

Aim:

The aim of my investigation is to look upon on how the drop height affects the rebound height due to different surfaces. There are many factors that can be tested in how a ball bounces. I will be testing five different surfaces, but based on my results I will come to a conclusion.

Prediction:

I predict that the rebound height will be higher if the dropping height is higher, provided the ball will drop on the same surface.

This is simply to say that gravitational potential energy of the tennis ball is changed to kinetic energy of the tennis ball. As the ball is falling it gains kinetic energy, the kinetic energy is maximum when the tennis ball is about to hit the surface. After hitting the surface, the kinetic energy of the tennis ball is changing to gravitational potential energy of the tennis ball.

3. Air resistance faced by the ball.

4. Temperature of the ball

I am going to investigate the height from which the tennis ball is dropped.

Plan:

If I drop a ball from a height of one meter the gravitational potential energy is changed to kinetic energy of the tennis ball.

The ball is losing gravitational potential energy and gaining kinetic energy when the ball hits the surface some of its kinetic energy is lost through sound and heat. This is because of the initial velocity of the ball is less when the velocity at which the ball hits the ground and consequently the height gained after rebound will be less.

The loss of kinetic energy by hitting the surface is also dependable on the surface itself. On a hard surface, the tennis ball will lose less kinetic energy and such it would bounce a higher height.

A soft surface will absorb more kinetic energy and bouncing would be less.

Method:

Conclusion

The results I have recorded were accurate, although I had one odd result. This may be due to taking the wrong readings of the bouncing heights.

To make my experiment more accurate, I could have used a sensor to measure the bouncing height of the tennis ball and repeat the experiment three times and found an average. I don't think I could really improve on the way (the plan or method) the experiment was performed because my results were quite accurate. I also found that the experiment was quite easy to set up as it was simple and not complicated.

Further experiments I could do to see the effect of bouncing height of a tennis ball would be to whether the following factors would make a difference in the bouncing height.

The surface on which the ball is dropped: I think the bouncing height would increase if the tennis ball is dropped on a hard surface.

1. ## Bouncing ball investigation.

Both surfaces share the same gradient. The second graph - Graph to show surface efficiency. Shows both lines have different trends. The wooden surface line displays a curve going down, showing lower efficiency in dealing with energy. The carpeted surface line also shows a line which is a curve going up, which may show a better efficiency with dealing with energy than the wooden surface.

0.16 80 The average efficiency is 62.8% (total efficiencies added together and divided by 10) This efficiency can be shown in a Sankey diagram: The trend on this graph shows that, in general, the higher the drop the lower the efficiency.

ball is dropped from the grater the diameter of the crater and that there is a steady increase in the crater diameter. I did a graph of my results it is shown on the next page. Here is my result table: - Here are my results from the experiment: - Average Height (cm)

2. ## investigating terminal velocity

This supports my predictions as I had thought that the time would increase when the height was raised and would decrease when the weight is increased. Evaluation After completing my investigation I conclude that my results are accurate and reliable.

1. ## Investigate the effect of temperature on the bounce height of a squash ball.

The heights I dropped the ball from were: 0.50m, 0.75m, 1.00m, 1.25m and 1.50m. To make sure the temperatures of the ball were accurate I left the ball in the water bath for 3 minutes as I knew from my previous preliminary results that 3 minutes is how long it takes the ball to reach thermal equilibrium.

2. ## 'How does the height a ball is dropped from effect the rebound height?'

The rebound height of the ball depends on the following factors: 1. The height from which it is dropped. 2. The surface at which it is failing. 3. Air resistance faced by the ball. 4. Temperature of the ball I am going to investigate the height from which the tennis ball is dropped.

of its kinetic energy is turned into sound and heat energy as well as still propelling itself back upwards (because it is a partially elastic). The coefficient of restitution is a measure of the balls elasticity and is the ratio between the ball's collision speed and its rebound speed.
