Newton’s third law is fundamental law used in classical mechanics, astronautical, aerospace, other dynamical phenomena. It must be regarded as true in these cases if it is quantitatively justified i.e. magnitude of action is precisely equal to reaction, the direction of action and reaction are exactly opposite. The law is not justified in many phenomena. Law is extended/generalized speculatively; some experiments may justify the same. This is theme of discussion.
