A textbook on a table is an example of balanced forces. The force of gravity pulling the book downward is balanced by the normal force exerted by the table in the upward direction, resulting in the book remaining stationary on the table.

There is no such thing as a balanced force or an unbalanced force. A groupof two or more forces may be balanced or unbalanced. The group of forces isbalanced if the vector sum of all the forces in the group is zero.
The force of gravity causes a book to fall, but someone has to push it to the edge of the desk, or off the desk so that the force of gravity is greater than the normal force acting on the book.
One force is never balanced or unbalanced. Two or more forces are balanced if their magnitudes and directions are such that they add up to no force at all. An example is: Two people in a tug-of-war. Each person pulls the rope as hard as he can, and the rope doesn't move ... just as if there were no force on it at all. If the forces don't add up to zero, then they're unbalanced. An example is: Two people pulling in the same direction on the same end of the rope.
A balanced force is the one in which if there is a force on one side of the object , on the other side there is a force of the same magnitude. example is a book kept on a table is at rest. 2 forces are acting on it. one is vertically downwards that is its weight(mg) while other is perpendicular to he surface(normal force exerted by the table) an unbalanced force is 2 forces acting in opposite directions have different magnitudes and the direction of the object is towards the direction of the dominant force. example is 2 children are pulling a rope one with a force of 100N and other with 50N. rope is pulled by the child applying a force of 100N.

The forces are unbalanced. The force of Friction is obviously greater than whatever force is pushing the book in the direction of travel, if one is pushing it at all. If the forces on the book were balanced, the book would continue to slide with a constant velocity.
A book sliding off a table is an example of an object experiencing an unbalanced force. The force of gravity pulling the book downward is greater than the frictional force between the book and the table, causing it to accelerate in the direction of the force.
An example of balanced forces acting on a static object is when a book is placed on a table. The force of gravity pulling the book downward is balanced by the normal force exerted by the table, keeping the book in place.
An example of unbalanced force causing a change in motion is when a person pushes a book across a table. The force exerted by the person is greater than the force of friction between the book and the table, causing the book to accelerate in the direction of the push.
As long as the book's velocity changes, there is a net forces acting on it - in other words, the forces are unbalanced. By the way ... How exactly does a book that is resting on a table slow down and come to a stop ?
My understanding that the unbalanced forces are the ones that push the object in one direction (cause motion), while the balanced forces simply cancel each other out. If I have a book sitting on the table, and equal forces pushing it to the right and the left, it will remain stationary. However, if I apply a third force pushing it down toward the edge of the table, there won't be anything to counterbalance it (except the frictional force from the table), so it will move towards the edge. - Cookie :)
