Which of the following is an example of potential energy?

C.

Explanation:

Kinetic Energy is defined as something that possesses energy because it is in motion. Potential Energy is something that is at rest that ha the potential to have kinetic energy when it is set in motion.

All of these other choices are in motion, hence, they have kinetic energy. The jar is at rest, so it has potential energy. All of those objects were are rest at one point and had kinetic energy, before they started moving. If the jar was to fall off the shelf, its potential energy would transfer to kinetic energy.

C. Glass jar sitting of a shelf

Explanation:

Because everything else is full of kinetic energy but moving, so the only item not using kinetic energy is the jar.

answer: the answer is a

a and b sometimes have a positive value
