Short explanation

Elastic potential energy is the energy stored in an elastic object when it is either stretched or compressed. This energy is a result of the object's deformation and is released when the object returns to its original shape. For example, when a spring is compressed, work is done on it, and this work is stored as elastic potential energy. The amount of energy stored can be calculated using the formula: elastic potential energy = 0.5 x spring constant x extension squared. Understanding this concept is crucial in applications involving springs and other elastic materials.
