Physics - Rotational Motion

Practise 28 JIPMER previous year questions on Rotational Motion, compiled from papers spanning 2005 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty JIPMER tests.

Rotational Motion has been asked in 0 of the 19 years of JIPMER papers analysed (2001–2019), with 28 questions in all. 11% of them were easy, 75% moderate and 14% tough. Most of its questions came from 2019, with 0 questions that year. In the last three years (2017–2019) it had 0 questions across 5 papers, about 0 per paper.

The chapter's 6 topics are not weighted equally: Moment of inertia of rigid bodies (9 questions, 32%), Rolling without Slipping (9 questions, 32%), and Torque (4 questions, 14%) have been asked the most. Rolling without Slipping has produced the most tough questions (2).
