Question

Distinguish between conservative and non-conservative forces with one example each.

Answer 1

Conservative force

force is said to be conservative if the work done by or against force is dependent only on the initial and the final position of the body and not on the path followed by the body.

Work done by the conservative force in a closed path is zero.

Gravitational force, magnetic force, electrostatic force, etc

Non conservative force

A force is said to be non-conservative if the work done by or against the force is dependent on the path followed by the body.

Work done by the non-conservative force in a closed path is not zero.

viscous force, induction force in cyclotron, etc.

Answer 2

Hey mate,

◆ Conservative force -
1. Here, the work done depends only on the initial and the final position of the body.
2. In closed path, work done is zero.
3. For example
gravity
electric force
elastic force

◆ Non-conservative force-
1. Here, the work done depends on the path followed by the body.
2. In closed path work done is not zero.
3. For example-
viscous force
rocket propulsion
air resistance

Hope that is useful...
