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

Explanation

Friction is the force that resists relative motion between two surfaces in contact, acting opposite to the direction of movement. It explains why objects eventually stop moving on a flat surface without a continuous applied force, and why rubbing your hands together generates heat. While friction can cause energy loss through heat, it is also essential for everyday actions like walking and braking a vehicle. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
