Question

which of the following is an example of potential energy? a glass jar sitting on a shelf a flag waving in the wind a ball rolling along a sidewalk electricity powering a radio

Explanation:

Potential energy is stored energy due to position or state. A glass jar on a shelf has gravitational potential energy (stored due to its height). A flag waving, ball rolling, and electricity powering a radio involve kinetic or other forms of energy (motion, electrical energy being used), not stored potential energy.

Answer:

A. a glass jar sitting on a shelf
