Match the column I with column II. Column I (i) When a body does work against friction, its kinetic energy (ii) Work done by a body is (iii) Power of a body varies inversely as (iv) When work done over a closed path is zero Column II (p) independent of time (q) time (r) force must be conservative (s) decreases
