what gravitational poentional energy? can you explain more?
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.
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.
