Question

Effect of roughness on frictional force​

Answer 1

Answer:

hope it's helpful please mark as brainliest and thank my answers

Explanation:

The relationship between the friction and normal force is linear, at forces greater than 1 N, for a finger contacting a nominally smooth surface. ... However, as the surface roughness increases the coefficient of friction increases, up to a point. At this point the coefficient of friction plateaus.
