Question

What is a conservative force? Why the work done by it on a particle moving in closed path is zero?

Answer 1

conservative force is the force that do not depend on the path its only depend on its initial and final position of the path.

The work done by it on a particle moving in closed path is zero because As conservative force is independent of path (it depends only on its final and initial position ) so displacement would be zero which results in zero work done in closed path .
