Sagot :

The following are the two elements that influence the force of friction: The surface's smoothness: The friction between bodies increases as the roughness of surfaces in contact with one another increases.

Between smooth surfaces, there will be less force of friction. How firmly the surfaces are pushed together and the sorts of surfaces involved determine how strong the force of friction is. Regarding the characteristics of the two surfaces in touch. The smoothness or roughness of the two surfaces that are in contact with each other determines friction. On the force exerted on these surfaces. The amount of friction produced is influenced by the object's smoothness and roughness.
