Gravitational field intensity = gradient of Gravitational potential = dV/dr
The gravitational potential gradient dV/dr is defined as the rate of change of gravitational potential with distance in the field. This is equal to the gravitational field intensity at that point.
U = gravitational potential energy = – GMm/r
Gravitational potential V = U/m = – GM/r
Gravitational field intensity I = dV/dr
= GM/r²
