6. Rotational Dynamics
• A continuation of Newton's second law
• In the linear case, the acceleration is not only
proportional to the net force, but it is also
inversely proportional to the inertia of the body,
which we call its mass.
"That ball has so much
rotational inertia!"
10. Vector Nature of Angular Quantities
Right-hand rule: When the fingers of the right
hand are curled around the rotation axis and
point in the direction of the rotation, then the
thumb points in the direction of ω.
