Newton`s 2nd Law of Motion:
... Mass is a measure of the amount of matter in an object. The amount of inertia an object has depends on its mass. The greater the mass of an object, the greater its inertia. Mass, then, can also be defined as a measure of the inertia of an object. Mass and weight are closely related but do not mean t ...
