Bouncy Ball Experiement

Aim: I want to investigate how high a ball will bounce when it has been dropped from different heights.

Hypothesis: I predict that when the ball is bounced it will bounce lower then the height it was dropped from.

Method:
The equipment I need:

• Golf Ball

• Ruler

• Stand with boss head and clamp

1. Attach the clamp to the stand

2. Attach the ruler onto the stand (make sure the zero mark is on the ground)

3. Hold the ball and drop it from the 100cm mark

4. Film the process to make sure you know where it bounces too

5. Repeat the experiment twice and record the measurements

6. Repeat the experiment using different heights

Variables:

Independent Variable: The height from where the ball drops.

Dependent Variable: The height of where the ball bounces too.

Controlled Variable: The surface the ball bounces on, the type of ball, the ruler.

Results:

Height Of Ball Dropped

100cm = 84cm                                   

70cm = 60.5cm

50cm = 44cm

20cm = 16.5cm
0cm = 0cm
