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 the value of abs plastic static friction coefficient?
With what material? Coefficient of friction is for two materials.
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic
Why the coefficient of static friction is greater thant the coefficient of kinetic friction?
When objects are at rest on each other (i.e. static friction) their microscopic irregularities can settle into each other - and can also form electrostatic bonds.
What is the coefficient of static friction for wood on rubber?
Over 9000!
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
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
What is more sliding friction or static friction?
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
What the value of abs plastic static friction coefficient?
With what material? Coefficient of friction is for two materials.
How does the coefficient of static friction for two surfaces in contact compare to the coefficient of kinetic friction for the same two surfaces?
The coefficient of static friction is always larger because it takes more initial force to move an object that is at rest.
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic
Is there a formula for friction?
simple one is: max friction = coefficient of static friction*normal force

Is coefficient of friction or coefficient of limiting friction are same?
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.
What is the equation for static friction?
Fs=mu*FNFs=Static Friction mu=coefficient of static friction FN=Normal force
An example of two surfaces that have a low coefficient of friction?
human joints are an excellent example. they have a static friction coefficient of .01 μs and a kinectic friction coefficient of .003 μkanother good example would be waxed wood on dry snow (as in a snowboard on a ski slope) this has a static friction coefficient of .04 μsHope this helped!
