Does the force of friction depend on the type of surface?

The force due to friction is generally independent of the contact area between the two surfaces. This means that even if you have two heavy objects of the same mass, where one is half as long and twice as high as the other one, they still experience the same frictional force when you drag them over the ground.

What does force of friction depend on?

Answer: Friction is a resistive force, which comes into play when there is a relative motion between two bodies in contact. The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.

How does the force of friction change with nature of surfaces in contact with each other?

Two rough surfaces in contact have a much smaller area of actual contact than their total area. When there is a greater normal force as a result of a greater applied force, the area of actual contact increases as does friction.

Which type of friction depends on the surface area of an object?

Under what circumstances can friction depend on surface area in contact? – Quora. Normal friction doesn’t, but fluid friction (drag) does. Even though surface area increases, the pressure (the force per area) decreases therefore the friction remains the same.

How does force of friction depend on the area of contact of two surfaces?

The force due to friction is generally independent of the contact area between the two surfaces. Note that this relationship breaks down when the surface area gets too small, since then the coefficient of friction increases because the object may begin to dig into the surface.

Does friction depends on the nature of object?

Friction depends on the nature of surfaces in contact. For a given pair of surfaces, friction depends upon the state of smoothness of those surfaces. The force of friction is greater if a rough surface is involved.

Is friction force depends on the nature of the surface explain it properly with an example?

Friction does not depend on the nature of the surface in contact.

What 2 things affect the friction 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.

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

What does the force of friction depend on?

Friction depends on the smoothness of the surfaces in contact. The force of friction depends on the nature of the surfaces in contact. The force of friction increases if the surfaces are pressed harder.

How does friction depend on area of contact surface?

Now, this decrease in pressure due to the force cancels out the increase in the frictional force thus developed on increasing the area. Hence the frictional force becomes independent of area of contact surface. Also Know, how does friction depend on the smoothness of the surface?

What are the different types of friction?

Types Of Friction. Following are the friction types which depend on the types of motion: Static Friction. Sliding Friction. Rolling Friction. Fluid Friction.

What are the properties of static friction?

Force of the static friction is independent of the area of contact between two surfaces. 2. The magnitude of maximum force is always comparative to the normal force; therefore if the normal force increases, the maximum external force that the object can endure without moving, also increases.
