Chapter 7 – Rotational Motion and the Law of Gravity
... 1. The object spins about an axis. 2. The axis of rotation is the line about which the rotation occurs. 3. Circular motion is defined as a point on an object that moves (rotates) around an axis. Since the direction of the motion is constantly changing, linear quantities cannot be used. The circular ...

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 ...
