Action and Reaction Forces are Always What

Q. Action and reaction forces are always what?

Ans. Action and reaction forces are always equal in magnitude but opposite in direction.

According to Newton’s third law of motion, every action has an equal and opposite reaction. 

The first object’s forces are equal in size to the second object’s forces. The first object’s force is directed in the opposite direction as the second object’s force. Equal and opposing action-reaction force pairs are commonly found in nature.

Let two masses, m1​ and m2,​ are pairs of masses applying force on each other, i.e., F.

Acceleration of masses will be a1= F/m1  ​ and a2= F/m2.

As a result, the mass affects the acceleration of masses.  As a result, these forces may not create equal magnitude accelerations. 

For example, Your body exerts a downward pull on the chair, while the chair exerts an upward force on your body when you sit in it. This connection results in two forces: a force on the chair and your body. Newton’s third law of motion deals with these two forces, known as action and reaction forces. So basically, Newton’s third law is: “For every action, there is an equal and opposite reaction.”

The statement implies that two forces act on the two interacting objects in every interaction.
