Physics - Motion In One Dimension

Practise 40 COMEDK previous year questions on Motion In One Dimension, compiled from papers spanning 2012 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 COMEDK tests.

Motion In One Dimension has been asked in 15 of the 15 years of COMEDK papers analysed (2012–2026), with 40 questions in all. 48% of them were easy, 48% moderate and 5% tough. Most of its questions came from 2023, with 7 questions that year. In the last three years (2024–2026) it had 14 questions across 9 papers, about 1.6 per paper.

The chapter's 6 topics are not weighted equally: Uniform Motion (12 questions, 30%), Motion Under Gravity (10 questions, 25%), and Graphs of motion in one dimension (7 questions, 18%) have been asked the most. Uniform Motion has also led over the last five years, with 8 questions. Uniform Motion has produced the most tough questions (2).
