Gravitational potential energy (GPE) is the energy an object possesses due to its position in a gravitational field
. It is usually represented by the symbol U_g and is given by the formula U_g = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above a reference point
. The gravitational potential energy increases as the object is lifted higher and decreases as it falls lower
