Answer 2

Answer:

Contact forces :-

Contact force is a force that is applied by objects in contact with each other. Contact force is governed by Newton’s Laws.

Contact force is responsible for most of the interactions we experience in daily life. Pushing a car up the hill, writing your name with a pen, or picking up a textbook from the table are all examples of contact force, and they are also examples of continuous force. On the other hand, hammering a nail, kicking a ball, etc are examples of impulse or momentary force.

Types of contact force :

1) Frictional Force: Friction is a force exerted by a surface against the motion of a body across its surface.

Friction is a type of contact force only.

2) Applied Force: Force which is applied to an object by another object.

Applied force may be contact force as well as non – contact force.

3) Normal Force: The normal force is also called Support force. The normal force is the support force exerted upon an object that is in contact with another fixed or stable object.
