Physics - Laws of Motion

Practise 208 JEE Main previous year questions on Laws of Motion, compiled from papers spanning 2002 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 JEE Main tests.

Laws of Motion has been asked in 22 of the 25 years of JEE Main papers analysed (2002–2026), with 208 questions in all. 32% of them were easy, 52% moderate and 16% tough. Most of its questions came from 2022, with 30 questions that year. In the last three years (2024–2026) it had 42 questions across 49 papers, about 0.9 per paper.

The chapter's 5 topics are not weighted equally: Frictional force (71 questions, 34%), Newton's laws of motion (70 questions, 34%), and Equilibrium of Forces (37 questions, 18%) have been asked the most. Frictional force has also led over the last five years, with 31 questions. Frictional force has produced the most tough questions (11).
