Physics - Gravitation

Practise 26 BITSAT previous year questions on Gravitation, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Gravitation has been asked in 14 of the 16 years of BITSAT papers analysed (2009–2024), with 26 questions in all. 38% of them were easy, 50% moderate and 12% tough. Most of its questions came from 2024, with 4 questions that year. In the last three years (2022–2024) it had 7 questions across 5 papers, about 1.4 per paper.

The chapter's 7 topics are not weighted equally: Gravitational potential and Potential Energy (9 questions, 35%), Kepler laws (4 questions, 15%), and Newton's Law of Gravitation (4 questions, 15%) have been asked the most. Gravitational potential and Potential Energy has also led over the last five years, with 5 questions. Acceleration Due to Gravity has produced the most tough questions (1).
