Chemical, gravitational and nuclear energies are nothing but potential energies for different types of forces in nature. Explain this statement clearly with examples

A system of particles has potential energy when these particles are held at certain distance apart against some force. For example, chemical energy is due to the chemial bonding between the atoms. Gravitational energy arises when the objects are held at some distance against the gravitational attraction. Nuclear energy arises due to the nuclear force acting between the nuclear particles
