Conventionally, the magnitude of gravitational potential energy for an object at infinity from the earth is : ((M = Mass of the earth; m = Mass of the object at infinity; R = Radius of the earth). |
-(G*M)/R2 -(G*M)/R -(G*M*m)/R Zero |
Zero |
Gravitational Potential Energy (U) = -(G*M*m)/r At infinity, r → infinity Therefore, U → 0. |
