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.

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. '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.

    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.
