Question

Define gravitational potential and give its units in S.I.

Answer 1

Gravitational potential: Gravitational potential at any point in the gravitational field is equal to work done in bringing unit mass from infinity to that point. It is represented by V_G.
∴ V_G = \(\frac{W}{M}\)
Where W = the work done in bringing mass M from infinity to that point
∴ S.I. unit of V_G = \(\frac{J}{\mathrm{kg}}\) = J. kg^-1
