Circular Motion and the Law of Gravity
... Rotational motion – the motion of an object that is spinning 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 constan ...
