Question

which of the following is an example of mechanical energy? a light bulb giving off light a rock sitting at the bottom of a pond a person riding a bicycle

Explanation:

Mechanical energy is the sum of kinetic and potential energy. A light bulb gives off light energy. A rock at the bottom of a pond has no motion (kinetic energy) and no height (potential energy relative to the pond bottom). A person riding a bicycle has kinetic energy (due to motion), which is a form of mechanical energy.

Answer:

a person riding a bicycle
