Elastic energy, for example, a stretched spring.

This is known as elastic energy. It is a type of potential energy.

Elastic potential energy refers to the potential energy stored as a result of deformation of an elastic object. An example of this is a spring, which springs back before it has gained elastic potential energy. After a spring gains elastic potential energy, it will be deformed.

There is chemical potential energy, heat potential energy, elastic potential, and gravitational potential energy.

There are three main types of potential energy: elastic potential energy, gravitational potential energy, and chemical potential energy. Elastic potential energy is stored in objects that can either be stretched or compressed. The more the object is stretched or compressed, the more elastic potential energy it'll have.
