When an object is lifted off the ground at any height

• gravitational potential energy

• mechanical potential energy

• nuclear potential energy

An object lifted of the ground has gravitational potential energy because

• if dropped, it has the potential to fall to the ground.

• the object that has the energy supplies the force to do the work.

• energy is stored in the nucleus of an atom.
