Write the expression for gravitational potential energy and gravitational potential at the surface of the Earth.
(N/A) The gravitational potential energy $U$ of a body of mass $m$ at the surface of the Earth is given by $U = -\frac{GM_{E}m}{R_{E}}$.
The gravitational potential $V$ at the surface of the Earth is defined as the gravitational potential energy per unit mass,given by $V = \frac{U}{m} = -\frac{GM_{E}}{R_{E}}$.
Here,$G$ is the universal gravitational constant,$M_{E}$ is the mass of the Earth,and $R_{E}$ is the radius of the Earth.
