Which of the following is NOT a type of potential energy?

Kinetic energy is the energy of an object in motion, which differentiates it fundamentally from potential energy. Potential energy, on the other hand, is stored energy based on an object's position or state. Gravitational energy depends on an object's height in a gravitational field, chemical energy is stored in the bonds of chemical compounds, and nuclear energy is associated with the forces holding the nucleus of an atom together. Since kinetic energy involves movement rather than storage based on position or condition, it is not classified as a type of potential energy.
