The smoothness of the contacting surfaces influences friction. If two surfaces are rough than if they are smooth, then is important to action witha greater force. However, friction decreases with smoothness only to a degree; friction actually increases between two extremely smooth surfaces because of increased attractive electrostatic forces between their atoms. Friction does not depend on the amount of surface area in contact between the moving bodies or (within certain limits) on the relative speed of the bodies. It does, however, depend on the magnitude of the forces holding the bodies together. When a body is moving over a horizontal surface, it presses down against the surface with a force equal to its weight, i.e., to the pull of gravity upon it; an increase in the weight of the body causes an increase in the amount of resistance offered to the relative motion of the surfaces in contact.
Answer:
factors affecting friction are as follow
Explanation:
there there are four main factors which affecting friction
1: nature of the surface
2: weight of the object
3: area of contact
and
4: type of surface of the object
