Potential energy is a relative thing What matters is the difference in potential energy between two points For different applications we define the zero to be in different places U = GMm/r sets the zero to be when the two masses are infinitely far away, at r > infinity So the PE at any finite separation is negativeDefinition of gravitational potential derivation of the formula for gravitational potentialdefinition of gravitational potential energyderivation of the forPhysics Formulas Gravitational Potential Energy The questions on this page test your ability to use the formula Change in GPE = mass × gravity × change in height You may also wish to learn the formula in characters GPE = mgh Question 1 A 1 Gravitational potential energy formula gcse physics
