Questions I. What happens to the gravitational potential energy (Energy) as the ball moves down? 2. What happens to the gravitational potential energy (Energy) as the ball moves up? If you moved the ball between a high point and a low point slowly, and then repeated the move from the same two ball has at each point be the same or different? Explain. 3. points more rapidly, would the energy the 4. What do you think is the shape of the plot of data in the Energy- Height' graph looks like? 5. What do you think that this means about the gravitational potential energy relative to the height?

Explanation / Answer

1.

As the ball moves down the gravitational potential energy decreases.

2.

As the ball moves up the gravitational potential energy increases.

3.

Since the gravitational potential energy is only dependent on the height of the object (given mass and g remains same), it won't matter whether you take it slowly or rapidly.

4.

A straight line

5.

This means that the gravitational potential energy changes linearly with height (it increases with increasing height and decreases with decresing height).
