Physics - Rotational Motion

Practise 16 NEST (NISER) previous year questions on Rotational Motion, compiled from papers spanning 2011 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEST (NISER) tests.

Rotational Motion has been asked in 13 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 16 questions in all. 6% of them were easy, 88% moderate and 6% tough. Most of its questions came from 2023, with 2 questions that year. In the last three years (2024–2026) it had 2 questions across 4 papers, about 0.5 per paper.

The chapter's 6 topics are not weighted equally: Rotational kinematics (7 questions, 44%), Angular momentum and Angular impulse (3 questions, 19%), and Moment of inertia of rigid bodies (2 questions, 13%) have been asked the most. Over the last five years the most frequent topics have been Rolling without Slipping (2), Rotational kinematics (1), and Angular momentum and Angular impulse (1). Frictional force has produced the most tough questions (1).
