When a stack of 3 books is placed on a table, there are two forces acting on the books: the action force and the reaction force.
1. Action Force: The action force is the force applied by the books on the table due to their weight. It is acting downwards and is equal to the weight of the books, which is determined by the mass of the books and the acceleration due to gravity.
2. Reaction Force: The reaction force is the equal and opposite force exerted by the table on the books. It acts upwards and counterbalances the action force to prevent the books from accelerating through the table.
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Therefore, the action force is the weight exerted by the books on the table, and the reaction force is the upward force exerted by the table on the books.
