Which force opposes the relative motion between two surfaces in contact?

Friction opposes the relative motion or attempted motion between two surfaces.

This multiple-choice question (MCQ) is based on the “Laws of Motion” chapter from Class 11th Physics in the NCERT curriculum for the CBSE academic year 2024-2025. It is designed to assess students’ understanding of essential concepts such as Newton’s three laws of motion, force, inertia and the relationship between force and motion. The MCQ format allows students to apply theoretical knowledge to solve problems effectively. By answering this question students will be able to demonstrate their comprehension of the laws that govern the motion of objects and test their ability to think critically and analytically about the subject.
