The potential energy of a car moving on a level road does not depend on its speed.

Question

Quizplus · Accepted Answer

The potential energy of a car only depends on its height above the ground and the force of gravity acting on it, not its speed. On a level road, the height and gravity force do not change, so the potential energy of the car remains constant regardless of its speed. However, the car's kinetic energy (the energy of its motion) does depend on its speed.
