Conservative and Non-conservative forces

Conservative Force:

A  force is said to be conservative, if the amount of work done in moving any object against that the force is independent of how the object moves from initial  to the final position.

Example: Gravitational force, force exerted by a spring, electostatic force between two charge ect.

Non-conservative Force:

A  force is said to be non-conservative, if the amount of work done by that force on an object moving between two points depends on the path taken between the points and the work does not zero

Example: Force of friction this an example of non-conservative forces.
