Witch of the following is the best exsample of potential energy

A water slid.

This is because you use energy to climb up the water slid, then once your up there you have the potential to use gravitational energy. Once you head down the slid you are using kinetic energy. Once you hit the bottom there is a splash that also used kinetic energy.

An object or living organism that is stationary (not moving) for example the car is stopped at the top of the hill
