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).

A

I only.

B

II only.

C

III only.

D
