Consider a system under the action of a conservative force. When work is done on the system it must in some way change the velocity of its constituent parts (by the Work Energy Theorem), and thus change the configuration of the system. We define potential energy as the energy of configuration of a conservative system, and relate it to work in the following

Unformatted text preview: way: U = - W In other words, work applied by a conservative force reduces the energy of configuration of a system (potential energy), converting it to kinetic energy. To see exactly how this conservation works, let's derive the expression for the potential energy of a system acted upon by gravity....
