Rigid dynamics studies how these bodies rotate, accelerate, and react to forces. It builds upon particle dynamics but introduces complex rotational mathematics, including tensors, inertia matrices, and multi-axis rotation. Why the Krishna Series is a Student Favorite
The book delves into the fundamental equations governing the motion of rigid bodies, using D'Alembert's principle to simplify dynamic problems into static ones. 3. Motion in Two Dimensions This includes the study of: Motion of a rigid body parallel to a fixed plane. Equations of motion (linear and angular). Problems involving rolling, sliding, and collisions. 4. Motion in Three Dimensions A more advanced section dealing with: Euler’s equations of motion. Motion of a body with a fixed point. The gyroscope and its dynamics. 5. Lagrangian and Hamiltonian Mechanics (Advanced Modules)
Use free online physics applets or simulations to visualize gyroscopic precession and nutation, mapping the visual movement directly back to Euler's mathematical equations.

Theorem 4 (Reduction by symmetry — Euler–Poincaré) If L is invariant under a Lie group G action, then dynamics reduce to the Lie algebra via the Euler–Poincaré equations. For rigid body with G = SO(3), reduced equations are Euler's equations. (Proof: Section 7.)
