Why the coefficient of static friction increase when frictional force increase?

I think the best way to describe the answer is to describe how static works. If you rub your feet on a carpet, the frictional force causes the atoms gain more electrons, and less neutrons(or vice versa, I forget the order). When you touch a doorknob after, the knob and your body(via socks) are evening out the amount of neutrons and electrons originally present. So, in conclusion, the frictional force increases because the static friction is increasing from the distributing of neutrons/electrons. Lemme guess: Finals?

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 happens to the static friction force as the mass is increased?
A force is a force, and independent of whatever it is is being applied to. One can discuss inertial, gravitational, or a frictional forces, and these things increase proportionally with mass increases.
What the value of abs plastic static friction coefficient?
With what material? Coefficient of friction is for two materials.
The coefficient of static friction between the tires of a car a dry road is 62 the mass of the car is 1500 kg what maximum force is obtainable?
Frictional force, F = coefficient of friction, u x normal reaction, R Maximum normal reaction = Weight => Maximum frictional force = 62 x 9.8 x 1500 = 911400 N
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic

Describe the factors that cause static friction between two surfaces to increase.?
A higher coefficient of static friction increases the static frictional force. A greater normal force also does this.
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 coefficient of static force?
i guess the question should be coefficient of static friction force.if it is so then it is just a dimensionless quantity signifying the degree to which the frictional force can oppose relative motion and prevent any relative motion.

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 2 things determine the friction between to objects?
Friction between two objects depends on the static coefficient of friction (if the object is currently not moving) and the normal force from the surface, acting in the direction opposite the direction of gravity.
What the value of abs plastic static friction coefficient?
With what material? Coefficient of friction is for two materials.
Method to be followed when determining the coefficient of static friction?
μs = Ff / F N= F A / Mgμs - static frictionFf - frictional forceF N - Normal forceF A - Applied forceMg - mass times gravity
Why frictional electricity is known as static electricity?
Becuase static electricity is generated by rubbing or by friction.
Does friction use static?
the charges does not move in a body the frictional electricity is called static eletricity
