Question

gravitational potential energy of an object depends on the mass of the object its height from the surface of earth and acceleration due to gravity using the method of dimensions derive an expression for potential energy

Answer 1

potential energy = work

       P.E = F×s

       = mg×h

P.E = mgh

Answer 2

Gravitational potential at a point in gravitational field is defined as the amount of work done in bringing a unit mass body from infinity to that point without acceleration.
