Answer 2

The normal force is the force that surfaces exert to prevent solid objects from passing through each other. Normal force is a contact force. If two surfaces are not in contact, they can't exert a normal force on each other

example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book
