According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object will exert an equal and opposite force on the first object. These forces occur in pairs and act on two different objects. The force acting on the first object is called the action force, and the force acting on the second object is called the reaction force. They are equal in magnitude but opposite in direction, ensuring that the net force acting on a system is always zero. This law is important in understanding the motion of objects and can be used to predict the behavior of physical systems.
