Question
Answer the following question.
Distinguish between conservative and nonconservative forces.
Solution
| 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. |
