... Summary of Newton’s Three Laws • An object tends to remain at rest, or, if moving, to continue moving at constant speed in a straight line (1st Law). Objects tend to resist changes in motion (inertia) – mass measures this. • (2nd Law) When there is a net force on an object, it will accelerate: a = ...

Chapter 7 – Rotational 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 ...
