Does the surface Affect the Bounce of a Dropped

Ball By :Gilbert Fulton

I hypothesize that the sand will have the most affect on the dropped ball

Hypothesis

Independent Variable: The type of surface the ball is being dropped on

Dependent Variable: The height of the ball after being dropped on the surface

Variables

The height the ball is dropped The same ball The same conditions when I experiment The same amount of force The same metric units used

Controlled Variables

Potential energy Elastic Friction Air resistance Gravity
