Final answer:

Gravitational potential energy is the energy an object has due to its position in a gravitational field, measured in joules (J), and is a form of mechanical energy.


Explanation:

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field relative to a reference point. This potential energy is measured in joules (J) and is a form of mechanical energy.

For example, lifting a mass against Earth's gravity involves converting work into gravitational potential energy: [tex]$mgh$[/tex] per unit of mass ([tex]$kg$[/tex]) at a height ([tex]$h$[/tex]).

During transformations, like a ball thrown upward converting kinetic energy to potential energy, energy changes forms while obeying the Law of Conservation of Energy.
