On what factors does friction depend?

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.

Does the size of an object affect its friction?

An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface and the light object. The characteristic of a high friction surface tends to be coarseness.

What affects the amount of friction on an object?

Frictional force depends on the nature of the surface in contact. The rougher the surface, the greater the friction involved. Frictional force is proportional to the pressing force, which is the weight of the body. It is independent of the area of contact.

Does friction depend on nature of object?

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

How does friction depend on the nature of the surface?

Frictional force depends on the nature of the surfaces in contact and increases with the increase in the roughness of the surface. If the surface is rough the interlocking becomes stronger thus increases the friction between the two surfaces.

Does friction depends on shape of the object explain?

The frictional force on an object in a fluid depends on its speed with respect to the fluid. The frictional force also depends on the shape of the object and the nature of the fluid. It is obvious that when objects move through fluids, they have to overcome friction acting on them. So, objects are given special shapes.

Does friction depend on surface area?

Friction does not depend on the amount of surface area in contact between the moving bodies or (within certain limits) on the relative speed of the bodies. It does, however, depend on the magnitude of the forces holding the bodies together.

Is the friction same for all objects?

No friction is not same for all surfaces . A polished surface have less frictional force and a rough surface have large frictional force . Hope this helps you .

Which force of friction depends on the shape of the object?

Hence, fluid friction depends on all three, the speed and shape of the object and the nature of the fluid.

Can friction force change the shape of an object?

Force can change the shape and size of objects. Friction force is the force arises between two surfaces in contact and is always in a direction opposite to the push.

What does the force of friction depend on?

The force of friction depends upon the coefficient of friction of the surface. The greater is the coefficient of friction of the surface the more is the force required to move it over that surface. The coefficient of friction, µ, is the amount of friction existing between two surfaces.

How do you find the coefficient of friction between two surfaces?

One of the ways to determine the coefficient of friction between two surfaces is to pull on an object, using a spring scale that is used to measure the weight of the object. If we lay an object on another surface and then pull it, we can determine the amount of force required to move the object into any surface.

Does coefficient of kinetic friction depend on speed?

The coefficient of kinetic friction should not depend on speed. Kinetic friction depends on acceleration, and acceleration depends on the change in speed over a given change in time. What is a high coefficient of friction? The coefficient of friction, µ, is a measure of the amount of friction existing between two surfaces.

How does the roughness of an object affect the friction?

The friction generated depends upon the roughness and smoothness of the sliding object. The rougher is the object the more friction will be generated and hence its movement will become restricted. The smoother is the object the more smoothly it can move.
