What is the clear difference between gravitational potential and gravitational potential energy ?Ans)A body A of mass m is placed in the gravitational field of a body B of mass M. The gravitational potential of body B at a point in the field is the work done is bringing unit mass from infinity to that point and is independent of body A. On the other hand, the gravitational potential energy of body A is the energy possessed by it due to its position in the field.In fact,Gravitational potential energy = mass of body(A) x gravitational potential
