▪︎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.
