Question

why does the roughness influence the force of friction ​

Answer 1

Answer:

, it is important to study other roughness parameters of surface texture and to correlate them with the coefficient of friction. The roughness parameter changes during surface preparation, owing to texture and hence affects the coefficient of friction.

Answer 2

Answer:

Explanation:

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.
