Conservative and Non-Conservative Forces

Conservative Force:

A system in which the total mechanical energy remains conserved is called a conservative system. The force acting in such a system are called conservative forces.

Non-Conservative Force:

In the presence of resistive forces in a system, mechanical energy does not remain conserved and gets dissipated. Such a system is called a non-conservative system and the resistive force is called a non-conservative force or dissipative force.
