Gravitation - NEET Previous Year Questions with Solutions

Orbital velocity (v₀) is the speed needed to maintain a circular orbit at a given radius: v₀ = √(GM/r). Escape velocity (vₑ) is the speed needed to break free from gravity entirely: vₑ = √(2GM/r). The key relation is vₑ = √2 × v₀. NEET frequently asks ratio-based questions using this relationship.

Yes, Gravitation is important for NEET 2025. It is a Class 11 Physics chapter listed explicitly in the NTA syllabus. With 1–3 questions appearing annually and predictable question types, it offers consistent scoring opportunity for prepared students. Focus on variation of g, orbital velocity, escape velocity, and Kepler's Third Law.

NEET typically asks 1 to 3 questions from Gravitation each year. Over the past decade, the average is approximately 2 questions per paper, worth 8 marks. Years like 2019 and 2022 had 3 questions. This makes Gravitation a reliable scoring chapter that should not be skipped.

Skipping Gravitation is not advisable. With 1–3 questions appearing every year at +4 marks each, skipping this chapter risks losing 4–12 marks. Since NEET ranks can shift by hundreds of positions on a 4-mark difference, Gravitation is a chapter where the effort-to-marks ratio strongly favours preparation. It can be covered thoroughly in 5–7 days.

The most important Gravitation topics for NEET are: variation of g with altitude and depth, orbital velocity and satellite time period, escape velocity, Kepler's Third Law (T² ∝ r³), and gravitational potential energy. These five sub-topics together account for approximately 70–80% of all Gravitation questions in NEET papers from 2010 to 2024.

epler's Third Law states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit: T² ∝ r³. In NEET, it is tested as ratio problems — for example, finding the time period of one planet given the time period and orbital radius of another. It is one of the most reliably repeated concepts in Gravitation PYQs.
