There are mainly 3 forces which acts on a book.
Listed below are the forces and their points:-
• <u>Earth's Gravitational force of attraction</u>- 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.
• <u>Force exerted on book while pushing it</u>- While we push a book, we apply Push Force, due to which the book moves on the pushing it on a table.
• <u>Frict</u><u>ional</u><u> </u><u>Force</u>- 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.
