System of Particles & Rotational Motion — NEET/JEE Questions, Notes & Weightage
Class 11 Mechanics II NEET weightage: Very High 59 questions
Covers centre of mass, torque, angular momentum, moment of inertia (for standard bodies), and rolling motion. One of the single highest-yield chapters in all of JEE/NEET Physics — moment-of-inertia and rolling-motion numericals are tested extensively, especially in JEE.

Why does JEE weight this chapter so heavily?
Rotational motion combines translational and rotational dynamics into compound problems (rolling without slipping, combined torque-and-acceleration systems) that test multiple concepts in a single, more difficult question — exactly what JEE favours.
What moment-of-inertia fact is most important?
Memorising the moment of inertia formulas for standard bodies (disc, ring, sphere, rod) about different axes, and applying the parallel/perpendicular axis theorems, is essential and tested constantly.
