Question

A roug surface decrease friction​

Answer 1

Explanation:

On the other hand, for various types of texture and materials the nature of the surface roughness may affect the dry sliding friction. In some case, making the surface smoother will reduce the friction, whereas in other cases, making the surface rougher will reduce the friction.

Hope it will help u

Answer 2

Answer:

u are correct

Explanation:

as rough surfaces make it easier to slide

so for example, ice,marble etc
