Physics - Rotational Motion

Practise 276 JEE Main previous year questions on Rotational Motion, compiled from papers spanning 2002 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 JEE Main tests.

Rotational Motion has been asked in 25 of the 25 years of JEE Main papers analysed (2002–2026), with 276 questions in all. 23% of them were easy, 46% moderate and 31% tough. Most of its questions came from 2021, with 39 questions that year. In the last three years (2024–2026) it had 68 questions across 49 papers, about 1.4 per paper.

The chapter's 7 topics are not weighted equally: Moment of inertia of rigid bodies (95 questions, 34%), Angular momentum and Angular impulse (52 questions, 19%), and Rotational kinematics (52 questions, 19%) have been asked the most. Moment of inertia of rigid bodies has also led over the last five years, with 43 questions. Moment of inertia of rigid bodies has produced the most tough questions (31).
