What factors determine the coefficient of friction?
quality of the Surface is affected to the Coefficient of friction
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.

What properties affect the force of friction?
The nature of the surface. A measure of this is the coefficient of friction.
Is friction affected by the amount of surface that is touching?
No: this is a common misconception Friction= Normal force* Coefficient of friction where Normal force= Mass* Acceleration due to gravity* Cos(angle of surface) and the coefficient of friction is an intrinsic property of the surface Therefore, only the mass of the object and the surface composition affect friction
How can an adjustable inclined plane be used to measure the coefficient of static friction and coefficient of static friction with a mass of 5.0?
Incline the plane until breakaway is achieved and note the angle. > A) Sin angle * 5 = force down (and parallel to) the slope in kgf. > B) Cos angle * 5 = force (weight) of block normal to slope surface. > Static friction coefficient = A / B
What is the function of coefficient of static friction?
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body
On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The force of friction!
A block accelerates at 3.2 down a plane inclined at an angle 30 degrees. Acceleration of gravity is 9.8. Whats the coefficient of static friction between the block and the inclined plane?
Static friction does not apply when the block is already moving. Without friction, the force on the block parallel to the surface of the incline is Fg*sin(angle), so the acceleration without friction is 9.8* sin(30) = 9.8 * (1/2) = 4.9 Since it is accelerating at 3.2, friction is slowing down the block by (4.9-3.2 = 1.7). The coefficient of kinetic friction is (1.7/4.9) = 0.346939
What does the coefficient of static friction represent?
In free space or on a frictionless surface, it takes no force to move something. Where there is friction, the ratio of (force necessary to start it moving horizontally)/(the object's weight) is the coefficient of static friction on the horizontal surface.
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 does the slope of the static friction vs normal force represent?
the slope of static friction & normal force represents "coefficient of friction' which is constant for a particular surface
