Well, Professor Newton has taught that the reaction is always equal and opposite
to the action, and we know that equal and opposite forces cancel each other. So it
seems that the answer to the question must be: They always do.
Never, they always cancel each other
Action and reaction forces do not cancel each other out because they act on different objects. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. These forces may have the same magnitude, but they act in opposite directions on two different objects, so they do not cancel each other out.
The force's don't cancel out each other, they act on different objects. Forces can cancel only if they act on the same object.
The action and reaction forces act on different objects. For two forces to cancel each other - and provide a net force of zero, for Newton's First Law - they must act on the same object.
The action and reaction forces do cancel each other out, so that there is a net force of zero. When you push on a wall, the wall does not move because the action force that you exert and the reaction force that the wall exerts are equal but opposite and the net force is zero.
Well in a single action-reaction pair, they cannot cancel out! The action and reaction forces act on different bodies. Lets say that we have a football. I kick it with 200 N of force. That is the action force, so the reaction force must be 200N(in the opposite direction) as well. The key here is that the reaction force did not act on the football, but on your foot! So the net force of the football is still 200 N in the direction I kicked it!Hope this helps some,-Sk Inventor

action reaction pairs
The action and reaction forces on a person swimming in water do not cancel each other out because they act on different objects. The person exerts a force on the water to move forward, and the water exerts an equal and opposite reaction force on the person, propelling them forward.
When two balanced forces cancel each other out, they are in a state of equilibrium. This means that the object they are acting on is not accelerating and is either at rest or moving at a constant velocity.
A body moves when there is an external force acting upon it. The action-reaction forces cancel each other out, but external forces can cause a net force resulting in acceleration and movement.
The action and reaction forces are the forces that cancel each other. They do not change an object motion or cause the object to accelerate.
