Does area of contact affect friction?
Question 5: Does friction depend on the surface area? Answer: Friction is a contact force when two surfaces interact. Hence, so friction depends on the surface of contact as the surface of contact increases the frictional force also increases.
Is frictional force and area of contact between the two surfaces are proportional?
Frictional force is proportional to the area of contact between the surfaces.
Is friction is independent of area of contact?
The area of contact on atomic scale is a very small fraction of total surface area. Therefore yes, friction is independent of area of contact. Note:Friction depends only on the nature of surfaces in contact and weight of the body.
Which is depends on the frictional force?
The magnitude of the frictional force depends on the weight of the object and roughness of the surface in contact. If the roughness is increased, the friction force will be increasing.
What determines how much friction occur between two surfaces?
The friction force depends on two factors: a) The materials that are in contact. The two materials and the nature of their surfaces. Rougher surfaces have higher coefficient of frictions but to slide apart.
Which depends on frictional force?
(i) Nature of the surfaces in contact i.e. whether surface is rough or smooth. Friction depends on the smoothness or roughness of the two surfaces which are in contact. A rough surface produces greater friction as compared to a smooth surface.
How does the force of friction change with increase in area in contact?
Since pressure equals force divided by the area of contact, it works out that the increase in friction generating area is exactly offset by the reduction in pressure; the resulting frictional forces, then, are dependent only on the frictional coefficient of the materials and the force holding them together.
Is friction dependent on the type of surfaces in contact?
Friction does not depend on the nature of the surface in contact.
