Question

what r the factors affecting
the friction

Answer 1

Answer: area of contact (normal force)

Explanation:

Answer 2

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.
