Column I	Column II
(A)	When a body does work against friction, kinetic energy	(p)	Independent of time
(B)	Work done by a body is	(q)	Time
(C)	Power of a body varies inversely as	(r)	Force must be conservative
(D)	When work done over a closed path is zero	(s)	decreases.

Verified by Experts

The correct answer is:

: When a body does some work against friction, its kinetic energy decreases.

A – s

Work done by a body is independent of time.

B – P

Power of body (P = W/t) varies inversely as time.

C – q

When work done over a closed path is zero, force must be conservative

D – r
