The energy is the capacity to do work. The various forms of energy are-
Kinetic energy- It is defined as the energy possessed by a body as a result of motion . It is called as - Kinetic energy =1/2 mass x velocity (1/2 mv)
Potential energy – it is the energy which is stored up in a body because of its position. Potential energy= mass x gravitational force x height of the body from ground (mgh)
