Answer:
A conservative force is a force that does zero work done in a closed path. ... Examples of conservative force: Gravitational force, spring force etc. On the other hand, non-conservative forces are those forces which cause loss of mechanical energy from the system. In the above case friction is the non-conservative force.

Conservative forces are those for which work done depends only on initial and final points. Example- Gravitational force, Electrostatic force.
Non-Conservative forces are those where the work done or the kinetic energy did depend on other factors such as the velocity or the particular path taken by the object. Example- Frictional force.
