The forms of energy that can be classified as potential energy from your list are:
- Gravitational energy
- Elastic energy
- Chemical energy
- Nuclear energy
Potential energy is stored energy based on an object's position or condition. Gravitational energy is related to an object's height, elastic energy relates to the stored energy in deformed elastic objects, and chemical energy is stored in the bonds of chemical compounds. Nuclear energy can also be considered a form of potential energy stored in the nucleus of an atom.
