This law is crucial in understanding the behavior of objects in various contexts, from everyday activities like walking to complex systems like rocket propulsion.

Newton's Third Law of Motion, articulated by Sir Isaac Newton in 1686, states that "for every action, there is an equal and opposite reaction." This fundamental principle of physics explains that forces always occur in pairs; when one body exerts a force on another, the second body exerts an equal and opposite force back on the first.

This law is crucial in understanding the behavior of objects in various contexts, from everyday activities like walking (where our feet push against the ground and the ground pushes back) to complex systems like rocket propulsion (where the expulsion of gas creates an equal and opposite thrust). Newton's Third Law is a cornerstone of classical mechanics and continues to be essential in both theoretical and applied physics.
