Question

Why is frictional force an example of a contact force?

Answer 1

Answer:

Frictional force and Muscular force requires contact between the object and its surface, thus they are an example of contact force. ... These force are exerted even if the two objects are separated by a distance r.

Answer 2

Answer:

Why is frictional force:-

Frictional force refers to the force generated by two surfaces that contacts and slide against each other. ... These forces are mainly affected by the surface texture and amount of force impelling them together. The angle and position of the object affect the amount of frictional force.

example of a contact force:-

Moving a couch across a floor, pushing a car up a hill, kicking a ball or pushing a desk 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.
