Friction.
Sliding friction prevents surfaces in contact from sliding past each other.
Friction prevents surfaces in contact from sliding past each other. There are several types of friction including dry friction, fluid friction, lubricated friction, skin friction and internal friction.
Parallel, surfaces are never perfect, and the peaks and valleys along these surfaces are the objects that interact to create resistance to movement parallel to the surfaces.

no substance is perfectly smooth.it has tiny bumps and bruises and when two surfaces move over each other the bumps and holes in get in each other's way.oil covers up these bumps.it also forms a layer between the two surfaces and prevents direct contact between them.there is very little direct contact between the holes and this way the friction is reduced
1 . By polishing the surfaces in contact 2 . By lubricating the surfaces in contact with oil or grease .
Friction is the force that doesn't want two surfaces to move against each other. For example, when you are rubbing the mat, the friction between you and the mat tries to prevent you from moving against the mat. Same with braking.
no
Prevent them from coming into contact.
