The Physics of Rotation

Key Concepts …

• Rotating masses possess rotational energy• An object can have both kinetic and rotational

energy• Moment of Inertia measures distribution of mass

wrt CM• Two identical mass objects can have very

different moments of inertia• Simple mathematical relationship links angular

velocity to linear velocity as long as no skidding takes place
