Gravitational Potential Energy (GPE) is defined as the work done against gravity to move a mass from one point to another. It is crucial to specify a reference point when discussing GPE, as it is relative to that point. The energy is not dependent on the motion of the mass; rather, it is determined solely by its position in relation to the reference point. This discussion clarifies the definition and significance of GPE in physics.
PREREQUISITESThis discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of energy, particularly in gravitational contexts.
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.Miraj Kayastha said: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?
