What is Elastic Potential Energy?

Elastic Potential Energy is a form of potential energy stored in objects that can be stretched or compressed, such as springs, rubber bands, or elastic materials. It is the energy that is stored when these objects are deformed from their natural or equilibrium positions due to an applied force. Elastic potential energy is associated with the tendency of these objects to return to their original shape or position when the force is removed.

The amount of elastic potential energy stored in an object depends on two main factors:

  1. The Spring Constant (k): This is a measure of the stiffness or elasticity of the object. Objects with a higher spring constant require more force to deform and store more elastic potential energy when stretched or compressed.
  2. The Amount of Deformation (Δx): This represents how much the object is stretched or compressed from its equilibrium position. The greater the deformation, the more elastic potential energy is stored.

All Formulae Related to Elastic Potential Energy

Elastic Potential Energy (PE_elastic) = 1/2 * k * (Δx)^2


  • PE_elastic is the elastic potential energy (measured in joules, J).
  • k is the spring constant (measured in newtons per meter, N/m).
  • Δx is the amount of deformation from the equilibrium position (measured in meters, m).
