Newton’s Third Law of Motion Formula
Newton’s third law of motion formula or mathematical expression is given as follows:
Let’s consider two objects A and B, and A exerts a force FAB on ‘B’ then B will also exert a similar force on A as FBA in the opposite direction such that
FAB = – FBA
OR
FAB + FBA = 0
This tells us that the total force exerted by the system comprising both A and B is zero.
Newton’s Third Law of Motion
Newton’s Third Law of Motion states that a given pair of bodies every action has equal and opposite reaction. Newton’s Third Law of Motion is one of the basic laws of physics and is very useful in various aspects. Newton’s Third Law represents a specific symmetry in the nature of forces and explains how they always exist in pairs, and one body cannot exert a force on another without also experiencing a force.
It is one of three laws of motion given by Sir Isaac Newton. Newton’s third law of motion highlights a fundamental principle of symmetry in nature. It tells us that forces are always part of a mutual exchange: when one body exerts a force on another, it inevitably experiences an equal and opposite force in return. In simpler terms, you can’t push or pull something without that something pushing or pulling back on you with the same strength but in the opposite direction.
In this article, we will learn about Newton’s third law of motion, its definition, formula, derivation, and examples of third law of motion.
