Generally no. The friction force is typically assumed independent of surface area, and proportional to the force between the two objects. By changing the contact area, you are changing how that force is concentrated. i.e. a small surface area means that your force is distributed across a small region, creating a high pressure (force/area) at the contact. By increasing the surface area, you distrubte that force and lower the pressure.
This is, however, an idealization and can break down in some instances.

∙ 12y agoIt does not. Friction is the product of coefficient of friction and normal force. The coefficient of friction depends on the materials in contact with each other. The normal force (the force holding them together) increases only the magnitude of friction. If you increase the area, you decrease the force per square inch (pressure) equally.

∙ 15y agoYes it is, the coefficient of friction μ is a surface's property of its ratio of frictional force.
Wiki User
∙ 11y agoWhen the nature of surfaces of the two body if in contact or are same then friction depends on area of contact .in this situation friction is directly proportional to area of contact.

∙ 9y agoFluid friction will vary with speed and the area of contact when referring to air friction or drag. When referring to surface friction then only the area of contact will vary.
Wiki User
∙ 11y agoNo,the coefficient of sliding friction doesn't depend upon the surface of area in contact. Those are calculated values from experiments.
Wiki User
∙ 10y agoNot at all. It's nominally proportional to the area of contact.

What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
there is no change.the coefficient of friction is independent of surface area.the matter will change only if normal reaction changes
Did isaac newton discover friction?
Several famous scientists and engineers contributed to our understanding of friction. They include Leonardo da Vinci, Guillaume Amontons, John Theophilus Desaguliers, Leonard Euler, and Charles-Augustin de Coulomb. Their findings are codified into these laws, 1. The force of friction is directly proportional to the applied load. (Amontons 1st Law) 2. The force of friction is independent of the apparent area of contact. (Amontons 2nd Law) 3. Kinetic friction is independent of the sliding velocity. (Coulomb's Law)
What are the three properties of drag?
There are four main properties of friction. These include it being an electrostatic force between two surfaces, it acts parallel to the surfaces that are moving against each other, it is independent of the area of the surfaces in contact with one another, and it never initiates motion - it only responds to it.
What factors that affecting friction?
Friction actually depends on the roughness or smoothness of the surfaces of the object. Even some smooth objects that we usually see everyday (ex. glass, mirrorr,etc.) aren't that smooth when magnified by strong microscopes. They still have rough surfaces therefore they can also have friction. Factors that affect friction: 1.) Adhesion 2.) Surface roughness 3.)The area of an object which is in contact with the surface. The larger the surface in contact, the greater friction. 4.)The texture of the surface and/or the object. The rougher/more uneven the surface/object, the greater the friction. 5.) The weight on the surface. The larger the weight, the greater the friction 6.)The angle of the surface. The greater the angle of the surface, the greater the friction.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
Why sliding friction greater than rolling friction and if the area of contact is same?
The FORCE of Friction is INDEPENDENT of Surface Area. Only the 'Coefficient of Friction', and the Force between the two Surfaces. Sliding Friction is greater than Rolling Friction ONLY if the Coefficient of Friction is GREATER for the Sliding Surfaces.
Does fluid friction vary with speed and area contact?
Fluid friction will vary with speed and the area of contact when referring to air friction or drag. When referring to surface friction then only the area of contact will vary.
What happened to the coefficients of friction as the surface area of the contact increased?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.

Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.
What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
there is no change.the coefficient of friction is independent of surface area.the matter will change only if normal reaction changes
What is law of dry friction?
The generalized answer is: Friction is equal to the forces acting upon an object.I know only 2 laws of friction.....The first states that friction between two surfaces is proportional to the force pressing one another am assuming its normal force or the perpendicular force.The other states friction is independent of the contact area. That is, the friction is the same whether the brick is on its large face, the smaller side or the small end. Hope this is accurate.When an object is moving, the friction is proportional and perpendicular to the normal force (N)Friction is independent of the area of contact so long as there is an area of contact.The coefficient of static friction is slightly greater than the coefficient of kinetic friction.Within rather large limits, kinetic friction is independent of velocity.Friction depends upon the nature of the surfaces in contact.
Does surface area have an effect on friction?
Yes greater the surface area coming into contact friction would increase
State laws of friction?
There are five laws of friction. These include "within large limits, kinetic friction is independent of velocity" and "friction depends on the type of surface where contact is made."
Why kinetic friction is less than sliding friction?
there is more surface area contact with kinetic friction as opposed to sliding friction
Will a wider area create more friction?
Actually, contact surface area has absolutely nothing to do with friction. This is due to pressure that will equalize over any area. All that matters is the material of the two surfaces in contact.
State laws of limiting friction?
1. the direction of force of friction is always opposite to the direction of motion.. 2. the magnitude of limiting friction depends upon the nature and state of polish of the two surfaces in contact and acts tangentially to the interface between them.. 3. the magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.. 4. the magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same..
