Topics 5
- Kinetic energy of a rotating rigid body; moment of inertia and radius of gyration; units, dimensions and physical significance
- Moments of inertia (formulae only) of a ring, solid and hollow cylinder, thin rod, solid and hollow sphere and disc
- Parallel and perpendicular axes theorems (statements) with simple examples of change of axis
