What is Potential Energy ?

Potential energy is that energy that is stored in a body. This energy can be stored in a number of ways

  1. Gravitational potential energy
  2. Chemical energy
  3. Elastic energy

http://www.sei.ie/Schools/Secondary_Schools/Subjects/Physics/Unit_2_-_Energy/Potential/Potential energy is due to the position of a body, this can be considered as gravitatitional energy or elastic energyA little of explanation of Gravitational potential energy for something falling or, re equilibrium energy for things that are wound up or displaced.http://id.mind.net/~zona/mstm/physics/mechanics/energy/gravitationalPotentialEnergy/gravitationalPotentialEnergy.html

But there are other potential energies, elastic

Hookes Law is the experimental proof of this elastic energy

Hookes law

Plot the graph of F(x) Vs x

the energy is represented by the area under the graph

This is because the area is force x distance = work = energy

from the 1st equation F=kx
