Question

Grive two exampies each for acontact
fore and aforce at a distances​

Answer 1

Answer:

Forces can be divided into those that act by direct contact—such as when you push on a door to open it—and those that act at adistance, where there is no apparent physical contact between the objects. Magnetism, and electrical charge, and gravitation are examples of forces that act at a distance.Pushing a car up a hill or kicking a ball across a room are some of the everydayexamples 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.
