Which of the following does not possess the ability to do work not because of motion?
(a) a sparrow flying in the sky
(b) a sparrow moving slowly on the ground
(c) a sparrow in the nest on a tree
(d) a squirrel going up a tree
Here, a sparrow flying in the sky, a sparrow moving slowly on the ground and a squirrel going up a tree have motion. so they possess kinetic energy which can be transformed into work.
Only a sparrow in the nest on a tree does not possess kinetic energy so it can't possess the ability to do work in terms of the motion.
Therefore, option (c) is correct.
