The scientific definition of work is using force to move an object over a distance. When you use your hand to lift the book off the floor, you are going against the force of gravity that is attracting it to the floor in order to lift the book in the air, from one location to the next. However, when you carry a book across the room, you are not fighting a force. As a matter of fact, the book has not left your hand; therefore, you are not moving it anywhere. The tricky thing is to not think of of the book as moving across the room - YOU are moving across the room; the book is still sitting in your hand. Now, if you THROW the book across the room, that is different entirely.
