Step 1:
: Recall the statement of Newton's Third Law of Motion

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.

Step 2:
: Understand the meaning of the terms in the law

- Action: This refers to the force exerted by one body on another body. - Equal and opposite reaction: This is the force exerted by the second body on the first body, which has the same magnitude but opposite direction as the action.

Step 3:
: Formulate the law in mathematical terms

Let F\_AB be the force exerted by body A on body B, and F\_BA be the force exerted by body B on body A. Then, according to Newton's Third Law of Motion: F\_{AB} = -F\_{BA} \tag{1} This equation means that the magnitude of the force exerted by body A on body B is equal to the magnitude of the force exerted by body B on body A, but their directions are opposite.

Final Answer

The formula for Newton's Third Law of Motion is given by equation (1) in the step above, which states that the force exerted by one body on another is equal in magnitude but opposite in direction to the force exerted by the second body on the first.
