What are systems of Particles and Rotational Motion?

Particle System and Rotational Motion begins with an explanation of the concept of a rigid body, which is:

A rigid body is one in which the distances between particles do not change despite the fact that a constant force is applied to them.

A rigid body that is not fixed can move in either direction or in a combination of directions.

For a rotating rigid body, the angular velocity remains constant at all times.
