An object has more potential energy the higher up it is. A ball was dropped from a height of 10 meters, when it hit the ground its velocity was 8 m/s. When the ball was dropped from a height of 20 meters, its velocity was 17 m/s. The higher the ball went the more potential energy it had to be converted into kinetic energy, which is why the higher ball was faster.

What is the claim in this passage?

a)

A ball was dropped from a height of 10 meters, when it hit the ground its velocity was 8 m/s. When the ball was dropped from a height of 20 meters, its velocity was 17 m/s.

b)

An object has more potential energy the higher up it is

c)

The higher the ball went the more potential energy it had to be converted into kinetic energy, which is why the higher ball was faster.
