Question

explain how rough surface effect friction ​

Answer 1

Answer:

Rougher surfaces have more friction between both body's.Heavier objects also have more friction because they press together with greater force.

Hope it helped ☺️

Answer 2

Answer:

Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

Explanation:

Surface roughness is a factor in friction when the materials are rough enough to cause serious abrasion. When one or more of the materials is relatively soft, much of the resistance to movement is caused by deformations or a plowing effect.
