Friction Coefficient Symbol 【Meaning, Copy and Paste】

Symbol of Friction Coefficient For You To Copy and Paste is μ.

Friction Coefficient Symbol

The coefficient of friction is the ratio of the force of resisting friction and normal force. It is dimensionless. Its value depends on the materials of the two bodies under consideration. If the value of the friction coefficient is less, the resistance will be less, and it will be easier for the object to move. The symbol for friction coefficient is the Greek letter “μ.” It is pronounced as “Mu.” 


The formula of friction of coefficient is as follows:

μ= Frictional Force / Normal Force

μ= Fr / N

μ = the symbol of friction coefficient

Fr = frictional force

N = normal force


The friction coefficient is a scalar quantity and is dimensionless. Thus, there is no unit for the coefficient of friction. 


You can easily find many websites that have a calculator system for the formulas. The same is the case for friction coefficients. They ask for the values of friction force and normal force and provide the answer of coefficient. All you need to do is to give them the values. And they will do the rest work for you.

Types Of Coefficient Of Friction:

There are some types of friction coefficients. They are kinetic, sliding, and static friction. The details for them are as follows:

Kinetic Friction:

It is defined as the force between moving bodies. The resisting force between two relatively moving objects gives us the value for kinetic friction. The force of kinetic friction depends on the material and nature of the surface. It is irrespective of the shape and appearance of the areas. 

Kinetic Friction Coefficient:

The ratio between kinetic friction and normal force is the coefficient of kinetic friction. It is denoted by the same symbol Mu but with subscript k, μk

The formula for the coefficient of kinetic friction is as follows:

Fk = μk ​η

μk = Fk / ​η

Static Friction:

The friction an object experiences while being placed on a surface is known as static friction. The static friction is irrespective of the area of contact between the object and the surface. 

Static Friction Coefficient:

It is the ratio between static frictional force and normal force. f The symbol for it is also Mu but will the subscript s, μs

The formula for the coefficient of static friction is as follows:

μs = F / N

Sliding Friction:

The friction produced between two objects when they are being slid with each other is known as sliding friction. Sliding friction between any two objects depends on:

  • the size of the objects,
  • the original speed of the objects, 
  • roughness or smoothness of the surface, 
  • pressure on any one of the objects. 

Sliding Friction Coefficient:

The ratio between the force of sliding friction and the force of objects pressing each other is called the sliding friction coefficient. The symbol for the sliding friction coefficient is also Mu with the subscript s, μs. Its formula is as follows:

μs = Fs / Ns
