Physics - Gravitation

Practise 11 NEST (NISER) previous year questions on Gravitation, compiled from papers spanning 2011 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 NEST (NISER) tests.

Gravitation has been asked in 8 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 11 questions in all. 0% of them were easy, 45% moderate and 55% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2024–2026) it had 5 questions across 4 papers, about 1.3 per paper.

The chapter's 5 topics are not weighted equally: Motion of satellite (4 questions, 36%), Gravitational potential and Potential Energy (3 questions, 27%), and Gravitational field (2 questions, 18%) have been asked the most. Motion of satellite has also led over the last five years, with 2 questions. Gravitational potential and Potential Energy has produced the most tough questions (3).

This chapter includes 11 questions compiled from NEST (NISER) papers spanning 2011 to 2026.

2.Are these questions only from NEST (NISER), or from other exams too?

These are NEST (NISER) questions specifically for the Gravitation chapter. Questions from other exams like JEE Main or NTA Abhyas (JEE Main) are organised separately under their respective exam sections.

3.Is Gravitation an important chapter for NEST (NISER) Physics?

Gravitation has appeared in 8 of the 16 years of NEST (NISER) papers covered here, with 11 questions across 10 papers - about one per paper it appears in.

4.What is the difficulty level of Gravitation questions in NEST (NISER)?

Of the 11 questions analysed for this chapter, 0% are easy, 45% moderate and 55% tough. 2024 had the most, with 3 questions.

5.Which topics in Gravitation should I focus on?

These topics have carried the most weightage in Gravitation:

  • Motion of satellite - 4 questions (36%)
  • Gravitational potential and Potential Energy - 3 questions (27%)
  • Gravitational field - 2 questions (18%)
  • Gravitational potential and Potential Energy has produced the most tough questions (3).
6.Is Gravitation's weightage in NEST (NISER) going up or down?

Across all 10 papers analysed, Gravitation has averaged about 1.1 questions per paper. In the last three years (2024–2026), that average has stayed about the same, at about 1.3 questions per paper. Use the year-wise numbers on this page for the exact trend before you decide how much time to give it.
