See lessDefine gravitation potential energy.
Abhishek kr. Modi
Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object.

See lessDefine Elastic potential energy.
Abhishek kr. Modi
Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process.
