If you pull back on a rubber band with a rock in it and then let go, which is this an example of.

elastic potential energy

Explanation:

The situation above shows an example of an "elastic potential energy." This type of potential energy depends on the force being applied to the elastic object.

In the situation above, the elastic object is the rubber band. The resultant energy is then being stored until such time that this object will be freed. Once this happens, the elastic object will revert to its original form and the rock will soar (be released).

The amount of energy that is being stored largely depends on the distance of the "stretch" being applied to the object. It is said that the greater the force, the greater the stretch and the greater the distance covered by the rock (and vice-versa).
