Conservative Force: A force is told conservative when the work completed by the force in moving a particle from an instance to another instance is independent of the path followed among these two points. Therefore the work provided by a conservative force among two points is the similar for all ways. The work done relays only on the particles initial a final point. In addition, the work completed by a conservative force along a closed path is zero.

The example of conservative tension is: Gravitational force, electrostatic force among two charges, magnetic force among two magnetic poles, elastic force exerted by an ideal spring, etc.

Non-conservative Force: When the work done by a force performing on a particle relays on the path followed among two given points or is not same to zero in a complete round trip is called the viscous force, Frictional force non-conservative force, etc., are examples of non-conservative forces..
