Question
A non-conservative force is one that
I. Has differing work done depending on the path taken by the object
II. Converts mechanical energy into various forms of internal energy, typically with more chaotic forms of motion
III. Gives work done as zero as long as particles move along a circular path (i.e. a path with no overall displacement).

Solution
The correct option is D I only
work done by non- conservative force is path dependent it depend on distance traveled.change in mechanical energy constitute of work done by all the external forces. work done by conservative forces is zero when particle is moving in circular path with no overall displacement.
