Ablock of mass m begins at rest at the top of a ramp at elevation h with whatever pe is associated with that height.

The PE associated with that height is given as, m×g×h

Explanation:

Potential energy (PE) is the energy possessed by an object when at rest. Its opposite is the kinetic energy (KE). When an object is at a certain height, it would possess potential energy because initially it is at rest. Also the value of the energy is determined by its mass, height and the force of gravity acting on it at that height.

So, the potential energy (PE) = mass× height× value of the gravitational force

                                                = m× g× h

Its unit is Joules. The potential energy of the mass would be converted to kinetic energy when it is in motion.
