Question

which of these is a source of potential (stored) energy? coal rain wind

Explanation:

Coal is a fossil fuel that stores chemical potential energy. When burned, the chemical bonds in coal break, releasing energy. Rain has kinetic energy as it falls (due to motion) and wind has kinetic energy (due to air in motion). Potential energy is stored energy. Coal's energy is stored in its chemical structure, making it a source of potential (stored) energy.

Answer:

coal
