Physics - Rotational Motion
Practise 25 Manipal (MET) previous year questions on Rotational Motion, compiled from papers spanning 2010 to 2023. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty Manipal (MET) tests.
Rotational Motion has been asked in 11 of the 15 years of Manipal (MET) papers analysed (2010–2024), with 25 questions in all. 40% of them were easy, 40% moderate and 20% tough. Most of its questions came from 2013, with 5 questions that year. In the last three years (2022–2024) it had 2 questions across 2 papers, about 1 per paper.
The chapter's 5 topics are not weighted equally: Moment of inertia of rigid bodies (10 questions, 40%), Angular momentum and Angular impulse (6 questions, 24%), and Rotational kinematics (4 questions, 16%) have been asked the most. Moment of inertia of rigid bodies has also led over the last five years, with 4 questions. Angular momentum and Angular impulse has produced the most tough questions (2).
