Question

Can you give me some examples for:

Normal Force and

Tangential forces

Answer 1

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. On occasions, a normal force is exerted horizontally between two objects that are in contact with each other. For instance, if a person leans against a wall, the wall pushes horizontally on the person.


Tangential force. a force which acts on a moving body in the direction of a tangent to the path of the body, its effect being to increase or diminish the velocity; - distinguished from a normal force, which acts at right angles to the tangent and changes the direction of the motion without changing the velocity.
