Newton’s Third Law of Motion
If an object ‘A’ exerts a force on object ‘B’, then object B must exert a force of equal magnitude and opposite direction back on object ‘A’.
This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself. We sometimes refer to this law loosely as action-reaction, where the force exerted is the action and the force experienced as a consequence is the reaction.
According to Newton’s third law, “To every action, there is always an equal and opposite reaction”.
It must be remembered that action and reaction always act on different objects. The third law of motion indicates that when one object exerts a force on another object, the second object instantaneously exerts a force back on the object. These two forces are always equal in magnitude, but opposite in direction.
These forces act on different objects and so they do not cancel each other. Thus Newton’s third law of motion describes the relationship between the forces of interaction between two objects.
For example, when we placed a wooden block on the ground, this block exerts a force equal to its weight, W = mg acting downwards to the ground. This is the action force. The ground exerts an equal and opposite force N = mg on the block in an upward direction. This is the reaction force.

Answer:
Every action has an equal and opposite reaction.
