contact force and non contact each and explain them.
Answers
Answer:
Contact force:-
A contact force is any force that requires contact to occur. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball across a room are some of the everyday examples where contact forces are at work.
Non contact force:-
A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it

Answer:
Contact forces are the forces which are due to the contact between two objects.

No contact forces are the forces which are there even when there is no contact between objects.
example- gravitational force
