Physics - Laws of Motion
Practise 9 NEST (NISER) previous year questions on Laws of Motion, compiled from papers spanning 2016 to 2023. 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.
Laws of Motion has been asked in 6 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 9 questions in all. 0% of them were easy, 56% moderate and 44% tough. Most of its questions came from 2020, with 3 questions that year. In the last three years (2024–2026) it had 0 questions across 4 papers, about 0 per paper.
The chapter's 3 topics are not weighted equally: Newton's laws of motion (6 questions, 67%), Frictional force (2 questions, 22%), and Spring force (1 question, 11%) have been asked the most. Newton's laws of motion has also led over the last five years, with 2 questions. Newton's laws of motion has produced the most tough questions (2).
