Book Free DemoGently push a book on a table. You observe that it stops after moving for some distance. Repeat this activity pushing the book from the opposite direction. 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.
