# what gravitational poentional energy? can you explain more?

Asked by Vaibhav Garg 14th October 2013, 11:18 PM

The potential energy of a body is due to its higher position above the earth and it is equal to the work done on the body against gravity in moving the body to that position.

W= mgh

where m=mass of the body,g=acceleration due to gravity and h=height of the body.

While Gravitational potential energy (U) is the amount of work done against gravity to take a body away from the earths surface (where h = 0).

U = -GMe m/r

Me = mass of earth, m = mass of object, r = distance between the center of earth and the object.
