Contrast elastic potential energy and chemical potential energy

Potential energy can be defined as the energy of something in relation to others, stresses within itself, or the electric charge.

Elastic potential energy the energy that is stored due to the deformation of an elastic object (i.e. a spring). This energy is equal to the energy needed to stretch the spring.

Chemical potential energy is energy stored in a substance's chemical bonds. This energy can be absorbed/released during either a chemical reaction or a phase transition.
