Physics - Laws of Motion

Practise 32 BITSAT previous year questions on Laws of Motion, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Laws of Motion has been asked in 15 of the 16 years of BITSAT papers analysed (2009–2024), with 32 questions in all. 22% of them were easy, 66% moderate and 13% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2022–2024) it had 7 questions across 4 papers, about 1.8 per paper.

The chapter's 5 topics are not weighted equally: Newton's laws of motion (15 questions, 47%), Frictional force (9 questions, 28%), and Equilibrium of Forces (4 questions, 13%) have been asked the most. Newton's laws of motion has also led over the last five years, with 7 questions. Newton's laws of motion has produced the most tough questions (3).
