$\huge{\tt{\red{}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}$

Examples for a contact force:-

The tyres of a car with road.

A ball moving on a floor experiences friction.

Examples force at a distance:-

The attraction and repulsion between two magnets.

A charged body (comb or balloon rubbed) attracts the pieces of paper.

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. In the first case the force is continuously applied by the person on the car, while in the second case the force is delivered in a short impulse.

At a distance force is when two interacting force is when two interacting objects are not touching, for example: the moon and the Earth's seas. At a distance forces encompasses gravity and magnetism.

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.

Distance forces are those types of forces that result even when the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite their physical separation. Examples of action-at-a-distance forces include gravitational forces.
