A nonconservative force is one in which the work done in moving an object/particle is dependent upon the path taken. A conservative force is path-independent, and depends only on the position of an object.


Gravity is an example of a conservative force.

The force of friction, however, is path-dependent. For example, if we push an object

1

m

across a rough surface, less energy will be lost as heat than if we push that same object

5

m

across the same surface. The work done (energy lost in this case) is dependent on the path taken.

Answer:

Non conservative force:-)

A force is said to be non conservative if the work done by that force depends upon the particle followed along with the initial and final position.

Friction as a non conservative force:-)

The direction of the frictional force is opposite to the direction of the motion. When a body is moved, say from point A to B and then back to a then work is required to be done during forward and backward motion. So, the net work done in a round trip is not zero. Hence, the frictional force is a non conservative force.
