Physics - Gravitation

Practise 46 COMEDK previous year questions on Gravitation, compiled from papers spanning 2012 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 COMEDK tests.

Gravitation has been asked in 13 of the 15 years of COMEDK papers analysed (2012–2026), with 46 questions in all. 48% of them were easy, 48% moderate and 4% tough. Most of its questions came from 2025, with 9 questions that year. In the last three years (2024–2026) it had 22 questions across 10 papers, about 2.2 per paper.

The chapter's 7 topics are not weighted equally: Gravitational potential and Potential Energy (18 questions, 39%), Acceleration Due to Gravity (12 questions, 26%), and Newton’s Law of Gravitation (6 questions, 13%) have been asked the most. Gravitational potential and Potential Energy has also led over the last five years, with 13 questions. Gravitational potential and Potential Energy has produced the most tough questions (1).
