Question

explain what gravitational potential energy is and give an example.

Explanation:

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It is calculated by $U = mgh$, where $m$ is mass, $g$ is gravitational - acceleration, and $h$ is height. For example, a book on a high shelf has gravitational potential energy. If it falls, this energy is converted to kinetic energy.

Answer:

Gravitational potential energy is the energy an object has because of its position in a gravitational field. An example is a book on a high shelf.
