Explanation:

FACTORS THAT AFFECT FRICTION - EXAMPLE

Friction between two surfaces depends on the smoothness of the surfaces in contact. A greater force is required to move the surfaces past each other when they are rough as compared to when they are smooth.

Also, it is more difficult to move a heavier object on the ground than a lighter one where the two objects are of the same material.

Answer 2

Answer:

Hlo Mate..

Answer-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. 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.
