when the surface is rough then the friction be______
Answers
Answer:
when the surface is rough then the friction will be more.
Explanation:
Friction occurs because no surface is perfectly smooth. 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:
Friction exist based on the relative motion between two surface sliding surface. ... When a surface is smooth, there is little or no resistance to motion when another smooth surface glides over it. However the result will be different if one surface is smooth and the other is rough.
Friction depends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth
Hence frictional force more in smooth surface
