According to Newton’s third law of motion, action force is always equal to the reaction force, but their directions are opposite, and they do not act on the same surface.
For example, if the book is moved from the surface of table by an action force in horizontal direction, a reaction force is generated by the surface of table in the opposite direction of the motion of the book but its magnitude will be the same.
Even though their magnitudes are the same and they act in opposite directions, they do not cancel each other as they act on different surfaces at the same time.
Final Answer:
Hence, the action is always equal to reaction according to Newton’s third law of motion.
