Does friction depend on the surface?

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.

Does the exposed surface area affect friction?

Friction is a contact force when two surfaces interact. Notice that both of these friction formulas ONLY depend on the coefficient of friction and the normal force. It does not depend the area of contact, it doesn’t depend on the sliding speed.

Does force of friction depends on inclination of surface?

Smoothness of surface. Roughness of surface.

How does friction depend upon the nature of the surface in contact?

The force of friction depends upon the irregularities present on the surface of the object. if the object has irregularities on its surface i.e. the surface is rough then the force of friction would be more . If there are no irregularities on the surface i.e. the surface is smooth then the force of friction decreases.

What are two factors that affect the frictional force between surfaces?

The factors that affect the friction between two surfaces are the weight of the object and the coefficient of friction of the surface.

Why does the friction depend on the nature of the surface?

Friction depends on the smoothness of the surfaces in contact. if the object has irregularities on its surface i.e. the surface is rough then the force of friction would be more . If there are no irregularities on the surface i.e. the surface is smooth then the force of friction decreases.

How does friction depend on the nature of the surface in contact?

Does the frictional force depend on surface area in contact?

In general, the frictional force between two solid objects in contact is not very dependent on surface area in contact. Take a block of wood cut from a 2×4 and push it across a table top. The force to push it at constant speed will not depend on whether it is the wider or narrower surface of the block in contact with the table.

Does friction depend on force or weight?

The force of friction depends on the nature of the surfaces in contact. The force of friction increases if the surfaces are pressed harder. Frictional force that comes into action before the start of the motion of an object is called static friction. Consequently, is friction dependent on weight? Friction DOES NOT depend on the mass of the body.

Does friction depend on the surface area of rope?

Here, true that friction does not depend on the surface area, but any part of the rope in contact with the surface is not just a single body, each part has its own term of friction force, which adds up to give a huge amount of friction force.

What happens when the normal force of friction is doubled?

If the normal force is doubled, the area of atomic contact is doubled and the friction is twice as large. However, if the geometric area is doubled while the normal force remains the same, the fraction of area in atomic contact is halved and the actual area in atomic contact hence the friction force remains constant.
