 These two forces are called action and reaction forces and are the subject of Newton’s third law of motion. Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

## What is equal between the action and reaction forces?

The law of action-reaction (Newton’s third law) explains the nature of the forces between the two interacting objects. According to the law, the force exerted by object 1 upon object 2 is equal in magnitude and opposite in direction to the force exerted by object 2 upon object 1.

## Does action and reaction forces act on the same object?

Action-reaction pairs are forces of equal magnitude and opposite direction that act on different object. They never act on the same object.

## Why action and reaction forces are not balanced forces?

Newton’s third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don’t cancel out.

## Do action and reaction forces act on the same body or different bodies?

Action and reaction act on two different bodies. Action and reaction are equal in magnitude but they act in opposite directions and there is simultaneous action and reaction.

## Can action and reaction balance each other?

Both forces are not on the same object hence the action and reaction forces cannot balance each other.

## Can an action force exist without a reaction force?

Without the action force there cannot be a reaction force, and thus there is no resulting forward motion. What happens when an object exerts a force on another object? Sometimes the identity of the pair of action and reaction forces in an interaction is not immediately obvious.

## Which statement is not true about action and reaction force?

D. Reaction force is twice the magnitude of action force is NOT TRUE. Explanation: Newton’s third law of motion introduced the concept of action and reaction.
