The primary causes of friction are surface roughness , the plowing effect and molecular adhesion.
Surface roughness is serious abrasion due to the roughness of the materials in contact.
Plowing effect involves deformations of the objects that cause resistance to movement.
Adhesion is the molecular force that results from two materials brought into close contact.
