Newton's laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. The first law states that if the net force (the vector sum of all forces acting on an object) is zero, then the velocity of the object is constant. Newton's first law is often referred to as the law of inertia.
