Write an expression for the potential energy of a body of mass m places at a height h above the earth’s surface. |
|
Answer» The work done W on the body in lifting it to a height h is W= force of gravity (mg) × displacement (h) = mgh This work is stored in the body when it is at a height h in the form of its gravitational potential energy. Gravitational potential energy U = mgh |
