Why is kinetic friction classified as a non-conservative force?
(a) It does zero work when the body moves once around any closed path
(b) Its work depends on the actual path length between two points
(c) It does no work on a body that moves with uniform speed in a straight line
(d) It always acts opposite to the direction of motion of the body
