  • Answers:
  • Gravitational potential is the amount of work done to bringing a unit mass body (1 kg mass) from infinity to a point in gravitational field, whereas gravitational potential energy is work done on any mass (m):gravitational potential is a case of gravitational potential energy for unit mass so,W=-GMm/r..and m=1 ::W=GM/r
