Write the change in gravitational potential energy of a body lifted at height $h$ from the surface of Earth.
(N/A) The gravitational potential energy $U$ of a body of mass $m$ at a height $h$ above the surface of the Earth is given by the work done against the gravitational force.
Since the force of gravity near the Earth's surface is $F = mg$,the work done to lift the body to height $h$ is $W = F \times h = mgh$.
Therefore,the change in gravitational potential energy is $\Delta U = mgh$.
Since the force of gravity near the Earth's surface is $F = mg$,the work done to lift the body to height $h$ is $W = F \times h = mgh$.
Therefore,the change in gravitational potential energy is $\Delta U = mgh$.
