What's newton's third law?

Answer

Newton's third law states that for every action, there is an equal and opposite reaction.

Solution

Newton's Third Law: Newton's third law of motion describes the interaction between two objects. When the first object exerts a force on the second object, the second object exerts a force of equal magnitude but in the opposite direction on the first object. This can be mathematically expressed as

\vec{F}_{12} = -\vec{F}_{21}

where

\vec{F}_{12}

is the force exerted by object 1 on object 2, and

\vec{F}_{21}

is the force exerted by object 2 on object 1

Key Concept

Action-Reaction Force Pairs

Explanation

The key concept of Newton's third law is the existence of action-reaction force pairs. When two bodies interact, they apply forces to each other that are equal in magnitude and opposite in direction. These forces act on different objects and are not to be cancelled out within a single object's force analysis.
