Physics - Rotational Motion

Practise 80 TS EAMCET previous year questions on Rotational Motion, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Rotational Motion has been asked in 22 of the 24 years of TS EAMCET papers analysed (2001–2024), with 80 questions in all. 34% of them were easy, 48% moderate and 19% tough. Most of its questions came from 2020, with 8 questions that year. In the last three years (2022–2024) it had 15 questions across 17 papers, about 0.9 per paper.

The chapter's 7 topics are not weighted equally: Moment of inertia of rigid bodies (30 questions, 38%), Rotational kinematics (13 questions, 16%), and Rolling without Slipping (12 questions, 15%) have been asked the most. Moment of inertia of rigid bodies has also led over the last five years, with 9 questions. Rolling without Slipping has produced the most tough questions (4).
