The force which applies the relative motion of two surfaces of bodies in contact is called Frictional force.
Factors affecting Friction
. nature of the surface
If the surface is rough then the friction is high
.area or the surface
Answer:
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.
Friction depends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth. ... It does, however, depend on the magnitude of the forces holding the bodies together.

Rubbing both hands together to create heat.
A sled sliding across snow or ice.
Skis sliding against snow.
A person sliding down a slide is an example of sliding friction.
A coaster sliding against a table.
A washing machine pushed along a floor.
An iron being pushed across material.
