QUESTION:

It is often said that “friction always opposes motion.” Give at least one example in which (a) static friction ?causes? motion, and (b) kinetic friction ?causes? motion.

ANSWER:

Solution 18DQ Example of static friction causing motion: Suppose there is a ball on the table and I am rolling the ball by putting the hand on the ball, the ball will start rolling. This is happening because of the static friction between the hand and ball and the static friction between the ball and table. For rolling we have to apply torque on the ball. Now I am not applying any force directly on the ball. I am j
