explain an example of normal force
Answers
Answer:
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.Yes; because according to the third law of motion, the magnitude of both the forces should be – equal and directions opposite and both forces should act on two different objects. Here both above conditions are fulfilled.
Answer:
While throwing a pen upwards there exists normal force and then the pen stops in the air for a sec during that time the normal force and gravitational force exists and the velocity is 0 and then gravity pulls it back towards the earth.
