Gently push a book on a table Fig. (a). You observe that it stops after moving for some distance. Repeat this activity pushing the book from the opposite direction Fig. (b). Does the book stop this time, too? Can you think of an explanation? Can we say that a force must be acting on the book opposing its motion? This force is called the force of friction.
Friction opposes relative motion between the surfaces of the book and the table.

Yes, the book stops this time too.
After sliding for some time, the book stops. As the surface of the table provides the frictional force to oppose the sliding of the book.
Yes, we can say that a force must be acting on the book opposing its motion.
