Answer 1

Why does the force of gravity do work on a car that rolls down a hill but no work when it rolls along a level part of the road? Gravity pushes the car toward the ground. So, when it is on a hill it moves down. ... When the ball is on a level road gravity does no work because the car can not go downward on a level surface

Answer 2

Explanation:

Gravity does no work on a car rolling on a level part of a road because the component of the force of gravity is zero in the horizontal direction.
