Question

force of friction will................ with roughness of surface ​

Answer 1

Answer:

Contact surface roughness has direct influence on the static friction coefficient. Generally, it can be assured that the static friction coefficient increases with surface roughness parameters. But, there is the difference in static friction coefficient values in the same roughness classes

hope it's helpful

Answer 2

Answer:

The resistance offered by friction depends directly on the force applied to move the two surfaces (calculated as vertical or normal force) and the roughness of the surfaces.
