Question

how do irregularitiesin a surface affect the force of friction​

Answer 1

Answer:

Friction is caused by the irregularities on the two surfaces which are in contact. The irregularities on both surfaces tend to lock into each other and this resists the motion of the object. The nature of the surface (smoothness or roughness) affects the friction.
