Name Newton’s first rules.

Newton’s laws are the three most important textbook laws of classical mechanics. The first Law, the law of inertia, says: if no forces act on a given object or their action compensates each other, then this body is at rest or moves at a constant speed.

Second Law: the acceleration of a body is directly proportional to the resultant forces applied to the body, and inversely proportional to its mass.

Third Law: action is equal to opposition, in other words, the forces with which the bodies interact with each other are equal in magnitude and directed along one straight line in opposite directions.
