Rotation of Rigid Bodies and the Parallel-Axis Theorem – Lecture 9 (University Physics I)

Intuitively, a rigid body:

1. A.Is an object whose mass is concentrated at a single point.
2. B.Is any object that happens to be spinning about a fixed axis.
3. C.Is an object whose mass changes as it rotates around an axis.
4. D.Is an idealized object that cannot be bent or deformed.
