The three laws of cattle are that the acting force and reaction force between two interacting objects are always equal in size and opposite in direction, and act on the same straight line. This law was put forward by isaac newton in his book Mathematical Principles of Natural Philosophy 1687. Newton's third law of motion and the first and second laws together constitute Newton's law of motion, and the basic laws of motion in classical mechanics are expounded.

Characteristics of three laws of cattle

Newton's third law of motion studies the mechanism of interaction and restriction between objects. The object of study is at least two objects, and the interaction between two or more objects can always be divided into several pairs of interacting objects. Action and reaction are mutual, interdependent and interdependent, and they are all based on each other's existence. No reaction, no action.

Force has materiality, and it cannot exist without objects (matter); Force is always produced by the interaction of two or more objects, and Newton's third law is also instantaneous, that is, the simultaneity of acting force and reaction force, which are produced, disappeared and changed at the same time. Action and reaction are equal, so it doesn't matter who they are.
