Answer 1

What is Contact and Non Contact Force?

Contact and non contact forces have a difference in their basic nature, let’s discuss these:

A force acting between two bodies in contact is called a contact force. For example, while pushing a table towards the wall is the contact force, or you are pulling something upwards is also a contact force because there is a direct contact between you and the object you are pulling.

A non contact force acts between the bodies that are not in direct contact. For example, an apple fell on Newton because of an invisible force called gravity.
