Question

what is contact force and non contact force​

Answer 1

Answer:

Contact Force

Contact force is a force that is applied by objects in contact with each other. The contact force acts on a point of direct contact between the two objects. This force can either be continuous as a continuous force or can be momentary in the form of an impulse. 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.

What is Non-Contact Force

A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interaction. When compared to the types of contact forces, there are very few non-contact forces.

Answer 2

${\fbox{\fbox{\huge\sf\purple{AnsWeR}}}}$

• Contact force ☞ The force exerted by a body to another body with physical contact is called contact force.

Example-: Frictional and Muscular force.

• Non contact force ☞ The force exerted by a body to another body without any physical contact is called Non contact force.

Example-: Gravitational, Magnetic and Electrostatic force .
