Document Summary
An object that was set in motion in past by some force, but that is no longer being acted on by a net force is moving but with zero acceleration. Aristotle : the natural state of all objects is to be at rest and a force is required to put it into motion. Newton 2nd law: (a body in motion remains in motion unless acted on by another force. ) Force is required for a (not motion) , and the amount of acceleration depends on the mass. Mass is related to the amount of acceleration ( or resistance to acceleration) It is sometimes referred to as inertial mass and doesn"t refer to the amount of substance in the object. Newton (n) is the si unit of force, and is the magnitude of the resultant force that if applied to an object mass of 1kg.
