Physics - Gravitation

Practise 6 IAT (IISER) previous year questions on Gravitation, compiled from papers spanning 2017 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 IAT (IISER) tests.

Gravitation has been asked in 6 of the 9 years of IAT (IISER) papers analysed (2017–2026), with 6 questions in all. 0% of them were easy, 67% moderate and 33% tough. Most of its questions came from 2026, with 1 question that year. In the last three years (2023–2026) it had 2 questions across 3 papers, about 0.7 per paper.

The chapter's 4 topics are not weighted equally: Gravitational potential and Potential Energy (2 questions, 33%), Motion of satellite (2 questions, 33%), and Kepler laws (1 question, 17%) have been asked the most. Gravitational potential and Potential Energy has also led over the last five years, with 1 question. Gravitational potential and Potential Energy has produced the most tough questions (1).
