Question

A book rest on a table. The book pushes downward on the table with a force of 8 N According to Newton's 3rd law of motion, what prevents the book from accelerating downward?

Answer 1

Step-by-step explanation:

The law of motion states that for every action there is an equal yet opposite reaction. so that mean that the book is being acted on by another force which would be the table. It does not move because the table is acting on it with 8n of upward force creating an equilibrium keeping the book at rest.

Answer 2

In the case of the table and the book, the gravitational attraction is absolutely negligible, since they are both so tiny. The force that the table experiences because of the book is what is being called normal force. The table then exerts an equal and opposite force.
