Yes.
This would just mean the force of friction could be greater than the normal force.
Also, keep in mind that the static coefficients are greater than or equal to the kinetic coefficients for the same two surfaces.
Some surfaces with higher than 1 static friction coefficients include:
- Platinum on platinum (1.2)
- Cast iron on cast iron (1.1)
- Silver on silver (1.4)
- Rubber on various surfaces
Note that it's just that most surfaces have a both coefficients below 1. Inclusion of Rubber in the list above gives us the clue that it's all about being "sticky" or "slippery"!

Give an example of friction?
Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.
What are 5 types of friction?
1. Static2. Sliding3. Rolling4. Air5. Fluid
What are 3 facts about friction?
1) friction thats lows things down is called dynamic friction 2) friction that stops things is called static friction 3) most of friction makes heat ( rubbing hands together )
How is air resistance related to force?
Gravity is the rate of acceleration at which objects fall to the ground. As an object falls, it pushes air out of its way. Air is pushed upwards in the same direction and with the same amount of force known as its air resistance.Air resistance is relevant to friction because it shows the impact of the object falling on the ground. If there was no friction the object would just drop in an instant.
Is it true that in a series circuit electric currents flow through more than one path?
more than 1
The coefficient of friction is always?
A. dimensionless
What type of force does low coefficient belong to?
Friction has a low coefficient, usually less than 1.
Coefficient of friction between concrete and concrete?
1
If your pulling 30 lb tire on a lawn what is the estimated weight youre actually pulling because of friction?
the equation for static friction coefficient is:static friction coefficient = force required to break bond / weight of object (tire)you need the friction coefficient between rubber and grass, say its 0.5, this means the force you have to apply to equal the friction force is:0.5 = x / 30x = 0.5 * 30x = 15 lbs fanything greater than 15 lbs f will break the bond and accelerate the tire.notes :1 / moving friction coefficient is usually less than static friction coefficient, so youve less drag once its moving.2 / friction coefficients are never greater than 1.0actually , some friction coefficients do exceed 1.0 , see google / friction coefficients table
There are two inclined planes ab and bc making a triangle of angles 45-90-45 90 degree is at b which has a pulley the string over it connects two masses m on ab and 2m on bc the friction coefficie?
(Coefficient of friction of plane ab) + 2(Coefficient of friction of plane bc) = 1 Coefficient of friction of plane ab = Coefficient of friction of plane bc = 1/3 = 0.33333......
What does the coefficient of kinetic friction depend on?
The coefficient of friction is a scalar value with no dimension. It is simply a ratio of the force of friction between two objects, to the force pressing those objects together (often the normal force). Slippery surfaces have lower coefficient of friction than rough surfaces.
What is the maximum acceleration a car can undergo if the coefficient of static friction between the tires and the ground is 0.78?
coefficient of friction = 0.8 tan theta use your calculator : 2nd tan ( 0.8) = 38.66 degrees
A hockey puck has a coefficient of kinetic friction of mk .1-. if the puck feels a normal force (fn) of 5N what is the frictional force that acts on the puck?
This type of problems about friction are extremely simple: You just multiply the normal force by the coefficient of friction to get the frictional force.
What is the equation for static friction?
Fs=mu*FNFs=Static Friction mu=coefficient of static friction FN=Normal force
What numbers will a correlation coefficient not ever be?
34.32245Correlation coefficient is less than -1 and greater than 1.Note: The Correlation coefficient is lies between -1 to 1 if it is 0 mean there is no correlation between them.
What is the SI unit for Friction?
[Simple Explanation]As friction is a force and the S.I. unit of force is Newton,the S.I. unit of friction is Newton.[Derivative Explanation]F=µN,where F is Frictional force,µ is coefficient of friction,and N is net normal reaction.N = -mgwhere mg is gravitational force whose SI unit is Newton.-(1)Coefficient of friction is dimensionless. -(2)From (1) and (2), SI unit of F = SI unit of N x SI unit of µ = NewtonHence SI of Friction is Newton.
How do you decrease friction between two surface?
1. Decrease the Force between the two Surfaces. 2. Lubricate the Surfaces, thus lowering the Coefficient of Friction between them.
