NEET Questions on the Laws of Motion

NEET questions on the Law of Motion chapters consist of topics like Conservation of linear momentum, Friction and its types, Circular motion and so on. Students must prepare every topic effectively to master the chapter during their preparation. The Law of Motion chapter will have a 7 per cent weightage in the NEET 2025 Exam.
Students must practice MCQs regularly to get a hold of the topics and concepts with time. Candidates can refer to various mock tests, sample papers and previous years' question papers to increase their pace and understand the question trends for each year. In this article, find the NEET questions on the laws of motion and more.
