Question

Answer the following question.

Distinguish between conservative and nonconservative forces.

Answer 1

	Conservative force	Non-conservative force
1.	If work done by or against a force is independent of the actual path, the force is said to be a conservative force.	If work done by or against a force is dependent of the actual path, the force is said to be a non- conservative force.
2.	During work done by a conservative force, the mechanical energy is conserved.	During work done by a nonconservative force, the mechanical energy may not be conserved.
3.	Work done is completely recoverable.	Work done is not recoverable.
4.	Example: gravitational force, magnetic force etc.	Example: Frictional force, air drag etc.
