Newton's third law of motion have been quoted from the Philosophi Naturalis Principia Mathematica published in 1687. The law as in original form states that to every action there is always an equal and opposite reaction: or the forces of two bodies on each other are always equal and are directed in opposite directions.' The equality of action and reaction is unconditional or unrestricted or uninfluenced by external factors in the law i.e. equality holds good in all cases. This is discussed here at macroscopic level and some anomalous results are found due to characteristics of the processes. If two balls of cloth and rubber are thrown on the wall then reaction on rubber ball is more than that on cloth ball. According to third law of motion action and reaction has to be equal irrespective of the characteristics. The same can be tested in elastic collisions when target is very-2 heavy than projectile.
