Question

what effect does surface roughens have on friction

a,it increase the friction

b, it decreases the friction
​

Answer 1

Answer:

your answer is (a) ..it increases the friction

Explanation:

Making a surface rougher or smoother may not always affect the sliding friction. In addition to this, for certain textures and materials, making a surface smoother reduces friction. But elsewhere, rougher surfaces can actually have less friction...
