Detailed explanation-1: -The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
Detailed explanation-2: -Ep = mgh. The gravitational potential energy stored in an object equals the work done to lift it.
Detailed explanation-3: -The change in gravitational potential energy, PEg, is PEg = mgh, with h being the increase in height and g the acceleration due to gravity. The gravitational potential energy of an object near Earth’s surface is due to its position in the mass-Earth system.
Detailed explanation-4: -gravitational potential energy is measured in joules (J) mass is measured in kilograms (kg) height is measured in metres (m) gravitational field strength (g) is measured in newtons per kilogram (N/kg)
