Relative to the table, the book remains stationary because there are no outside forces acting on it except gravity which keeps it lying on the table.
All of the forces together balance out. The resultant of the forces is therefore nil. That applies to all equilibrium.
Not quite sure I understand the rather vague question. But gravity ensures the book remains stationary on the level tabletop. If the table is tilted enough, the book will slide down the slope, still governed by gravity. If I gave the book a shove and it slid off the level tabletop, I would be using a physical force.

Take the example of a book resting on a table. The downward force of the book's weight is matched exactly by the upward resistance of the table - hence the book remains where it is. (If the table was very flimsy, and unable to support the weight of the book, the book would accelerate towards the ground.)

The book will not fall to the ground because of the force of gravity pulling it down and the normal force exerted by the table pushing it up. These two forces are equal and opposite, resulting in a balanced system where the book remains stationary.

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.
The book belongs to Sarah. The word "on" is a preposition in the sentence.
The's no single word that you can use to replace is. It depends on the context.ExamplesThe book is lying on the table (for The book is on the table).The castle stands at the top of the mountain (for The castle is at the top of the mountain).
