Question

what is gravitational potential energy?​

Answer 1

It can be defined as the energy possessed by an object when taken from one point in a field to another, against or in the direction of field.

Basically it is the same concept as of an electric field, only the work done by gravitational force is positive. In fact, I think Einstein devised the concept of a potential of a field so we could know mass/charge independently, how much field a particular portion in space possesses. This becomes useful for a general parameterization for n-dimensional space. Moreover, the Stoke's and Green's theorems help us calculate various curls and volumes within a vector field.

curl F = ▽ × F

Answer 2

Explanation:

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.
