Sliding friction causes a book to slow down and stop when pushed.

Might also be known as dynamic friction.
YES, YEA it is Yes it is a force. If not then we would be slipping around. What i have heard is that friction causes a pull in some ways. Say you slid a pencil on the floor with nothing in it's path. Now if you know what inetia (not a force) then you would know that the pencil would stop because of a outside force. And that force is friction. Friction had reduced the pencils speed when it rubbed together on the floor. Now if the pencil was givin more force when you pushed it and the floor was more slik then the pencil would have traveled alot more. This is because the force of friction is a less amount when one surface is smoother. I know this is a horrible explanation but this is what helps me think of the forces. And this is going to prove to my teacher that friction is a force and that inertia is not.
The book slides with constant velocity.
Static friction
Look for a Book Fool. >.<
Friction.
In fact, there is an infinite number of answers because force is a vector, meaning that it has a magnitude and an orientation. For example, if someone pushes horizontaly onto the book (10N) and the friction is 8N in the opposite direction, the resultant force is 2N. But if the book is pushed at an angle, the resultant force changes.

Yes, if an unbalanced force acts on the book, such as friction, which will slow the book down and eventually cause it to stop.
The book slides with constant velocity.
The force of friction is NOT ALWAYS directed opposite the direction an object is moving. Consider, for example, an object (like a book) resting on a piece of paper on a table. If you gently pull the paper and the book moves with the paper, friction between the paper and the book is causing the book to move in the same direction as the paper. Even if you pull a bit faster and the book slides in the same direction as the paper motion, but a little bit slower, the friction is the force which is pulling the book along--in the same direction of the paper motion.The direction friction is acting is opposite the direction of the relative SLIDING or attempted sliding of surfaces. In the cases above, without friction, the book would slide opposite the direction of paper motion, so the friction is in the same direction, accelerating the book along with the paper. In the first case, the book's acceleration is the same as the paper's; in the second, the book's acceleration is less than the paper's causing the book to actually slide backwards relative to the paper's motion.
Static friction
When you push a book, it stops because of the force you are applying to it. The friction between the book and the surface it is resting on counteracts the force you are applying, bringing the book to a stop.
Yes, Sliding friction opposes the movement of the book, slowing it down.
This is the example of Newton third law and law of inertia.
static friction, friction between two non-moving objects.
non-friction?
