Bouncy Ball

Bouncing Balls

Aim:
I want to find out if there is a relationship between how high a ball is dropped from and how high it bounces up.

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

Method:
The equipment that I will need is:

• Bouncy 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 50cm and drop.
4. Record the height of the bounce measuring the bottom of the ball.
5. Repeat the experiment twice more and record the average measurement.
6. Repeat the whole experiment using heights of 60cm, 70cm, 80cm, 90cm, 100cm

                                      
Variables:

Independent (changing) Variable = The height of the drop
Dependent (measured) Variable = The height of the bounce

Results:

Height of drop	Height of bounce on carpet	Height of Bounce of tarsal
80 cm	31 cm	35 cm
90 cm	31 cm	44 cm
100 cm	39 cm	47 cm

Findings:

1.At 80 cm the ball bounce at 31 cm on carpet and the other ball bounce at 35 cm on tarsal.

2.At 90 cm the ball bounce at 31 cm on carpet and the other ball bounce at 44 cm on tarsal.

3.At 100 cm the ball bounce at 39 cm on carpet and the other ball bounce at 47 cm on tarsal. 

Discussion:

Conclusion: When the ball was drop on 100 cm in the carpet the ball bounce 39 cm and in the tarsal the ball bounce 47 cm.
