Newton's third law of motion states that for every action (force) in nature, there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. This law represents a certain symmetry in nature, where forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself
. This principle is fundamental to our understanding of the behavior of objects and is the basis for many phenomena, including the operation of rockets and the movement of vehicles and aircraft
