Question

If a particle moves under the action of a conservation sysytem of forces, then what is the sum of its KE andPE?

Answer 1

Answer:

A conservative force is one for which the work done is independent of path. Equivalently, a force is conservative if the work done over any closed path is zero. A non-conservative force is one for which the work done depends on the path. For a conservative force, the infinitesimal work is an exact differential.
