Answer 1

Friction is caused by the irregularities on the two surfaces in contact. Larger the irregularities, rougher is the surface and more the friction. Thus, the smoothness of the surface affects the frictional force.

Answer 2

Answer:

2)Friction is caused by the irregularities on the two surfaces in contact. Larger the irregularities, rougher is the surfaceand more the friction. Thus, thesmoothness of the surface affects thefrictional force.

3) A ball on the smooth surface rolls faster than the ball onrough surface because there is less friction in smooth surface compared torough surface. Friction is the force that occurs opposite to the direction of motion.
