Question

Bart carried his skateboard up a hill and then rode the skateboard down the hill. When he reached the bottom of the hill, he rolled to a stop. When did Bart have the most potential energy?

Answer 1

Explanation:

The potential energy of an object is given by :

P = mgh

Where,

m is mass, g acceleration due to gravity and h is the height reached by the object.

The potential energy of an object is directly proportional to the height of the object. It means that when the skateboard reaches at the maximum height, it has highest potential energy.
