the si unit of gravitational potential is

Subject. The newton (symbol: N) is the unit of force (any kind of force, not only the gravitational one) derived in the SI system; it is equal to the amount of force required to accelerate a mass of one kilogram at a rate of one metre per second per second. Gravitational potential may be expressed as; ψ g (mass) per unit mass = Eg/M = MgZ/M = gZ 1.
