What is meant by normal force?
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.
What is the best definition of normal force?
The normal force is an everyday force that is felt when a surface pushes against an object that is placed on that surface. For example, when a book is placed on a table, the normal force keeps the book from falling through the table.
What are normal forces in physics?
The normal force is the support force exerted upon an object that is in contact with another stable object. For 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.
Is normal force always 0?
For an object moving horizontally on a surface, the normal force is perpendicular to the direction of the displacement, so that the work done by it is zero.
