Question

How irregularities increases friction

Answer 1

friction is due to the irregularities of a surface and as they increase the friction increases

Answer 2

Irregularities on surfaces: Friction is created because of irregularities on surfaces. The irregularities on surfaces result in interlocking of two surfaces. The interlocking between two surfaces creates friction. Hence, the force of friction will be greater in case of rough surface than in case of smooth surface.
