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.
Why the coefficient of friction cannot be zero?
The coefficient of friction is an empirical measurement and has to be measured experimentally, and cannot be found through calculations. Rougher surfaces tend to have higher effective values. Most dry materials in combination have friction coefficient values between 0.3 and 0.6. Values outside this range are rarer, but Teflon, for example, can have a coefficient as low as 0.04. Therefore, a value of zero would mean no friction at all, an ELUSIVE property even magnetic levitation vehicles have drag.
What factors determine the coefficient of friction?
quality of the Surface is affected to the Coefficient of friction
What is the coefficient of friction of linoleum rubber?
You need two different materials to determine the coefficient of friction. Without another material you cannot know what the coefficient of friction is.
What is the formula for Coefficient of friction?
(Static coefficient of friction) Cf = horizontal force (newtons) required to overcome static resistance / vertical force (newtons) due to objects mass * acceleration due to gravity. Note: Moving friction coefficient is generally less.
Is the coefficient of friction on a horizontal plane between to substances the same as the coefficient of friction on the incline plane?
POMBO
How can you find the coefficient of friction force only given mass and theta?
The coefficient of friction is the tangent of the angle theta where the angle is measured from horizontal when the mass first starts to slip

What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?
.419 .419
Does the coefficient of kinetic friction depend on the weight of the block?
No, It does not depends on weight of block because this weight of block is being balanced by normal force. So by increasing weight of block, there is no effect on coefficient of friction.
What is the amount of horizontal force required to start in motion an object sitting on a horizontal surface must be great than what?
multiply coefficient of static friction by object mass
What is cone friction?
A cone in which the resultant force exerted by one flat horizontal surface on another must be located when both surfaces are at rest, as determined by the coefficient of static friction.

What horizontal force P is required to drag a sack of rice weighing 110 pounds. in a horizontal floor if the coefficient of friction between the floor on the sack of rice is 0.25?
27.5 lbs
A solid homogenous sphere rolls without slipping down a plane that makes an angle of 30 degree with the horizontal find the linear acceleration of the sphere and the minimum coefficient of friction?
There is no minimum value for the coefficient of friction. And the linear acceleration will depend on its unknown value.
Is the coefficient of friction up to 13 unit?
No. Coefficient of friction is not measured in units.
What factors determine the coefficient of friction?
quality of the Surface is affected to the Coefficient of friction
