Gravitational Potential energy is the work done against the gravity to move a mass from one point to the other.

So if a mass was falling down to the earth, how is the potential energy defined?

It does not matter whether the body is moving or stationary.Gravitational potential energy of a body at a certain position is defined only in relation to another point. So you just have to tell us what the other point is. The gravitational potential energy in relation to that point, as you have said, is equal to the work done against gravity in moving the body from that point to its current position.

Let me get that straight. You defined potential energy and then asked how potential energy is defined. Seems like the first part of your post answers the question in the second part of your post. What is the point of this thread?
