FORCE-:

IT IS A PULL OR PUSH.

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.EG:- 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.Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays.
