The law states that the vector total of the forces (denoted by F) on a body is equivalent to the product of the mass (denoted by m) of that body and its acceleration (denoted by a). The second law also assumes that an object is in an inertial frame of reference. This frame means that this body will remain stationary or keep moving at a constant velocity. An inertial frame of reference is one in which the forces acting on a body, whether static or stationary, have a net force of zero. This law assumes that an object is in an inertial frame of reference. The first law states that an object either remains static or will continue to move at a constant speed unless it is influenced by another force. These three laws have been written in many different forms over the centuries, at least three, but they can be expressed briefly as follows: Newtonian mechanics is a field that is focused on the set of laws that govern the behavior of an object after forces act on that object. These laws laid the foundations for Newtonian mechanics, otherwise known as classical mechanics. Newton’s famous laws of motion are three in number. What are Newton's Laws? Formula for Newton's Second Law of Motion.
