boncing ball

aim: to find out how high the ball bounces when dropped at a certain height.

hypothesis 

I predict that the higher the ball is dropped from, the higher it bounces. 

Method:The equipment that I will need is:
Golf ball
Ruler
Stand with boss head and clamp

1. Attach the clamp to the stand.
2. Clamp the ruler onto the stand so that the zero mark is on the ground.
3. Hold the bottom of the ball on 100cm and drop.
4. Using a camera, record the bounce.
5. Record the height of the bounce measuring the bottom of the ball.
6. Repeat the experiment twice more and record the average measurement.
7. Repeat the whole experiment using heights of 80cm, 60cm, 40cm, 20cm.

                                      Results:

Height of Drop	Height of Bounce
100cm	87cm
80cm	69cm
60cm	16cm
40cm	12cm
20cm	18cm
0cm	0cm
