These chapters extend Newtonian mechanics to rigid bodies: torque, moment of inertia, rotational kinetic energy, and angular momentum conservation. The 13th edition improves upon earlier versions by including more worked examples on combined translational-rotational motion (e.g., a yo-yo or rolling sphere). Parallel-axis theorem and combined equilibrium problems are well-illustrated. moment of inertia
