Answer the following questions related to Newton’s third law of motion:
(a) State Newton’s third law of motion.
(b) List any three characteristic features of an action–reaction force pair.
(c) A block of mass m rests on a horizontal table. Draw separate free-body diagrams of (i) the block and (ii) the table, clearly labelling the action and reaction forces acting on each body.
(d) The two forces identified in part (c) are equal in magnitude and opposite in direction. In one or two sentences, explain why these forces do not cancel each other when we calculate the net force on the block.
