Question

A person is pushing a book lying on a table. Identify the different forces that act on

the book and hence mark their directions.

Answer 1

There are mainly 3 forces which acts on a book.

Listed below are the forces and their points:-

• Earth's Gravitational force of attraction- Usually, we may not consider or notice this force, but when a book falls, we understand this, because the book falls due to this gravitational force.

• Force exerted on book while pushing it- While we push a book, we apply Push Force, due to which the book moves on the pushing it on a table.

• Frictional Force- We notice that while pushing a book, it does not continuously move in motion. At a certain distance, this Frictional force increases and therefore, the book comes to a halt.

Location- Opposite of exerted force in all directions

Answer 2

Step-by-step explanation:

There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.
