Kinetic Friction Calculator is an online tool for calculating Kinetic Friction easily. It takes the inputs and calculates the Kinetic Friction, so it is handy for solving problems requiring Kinetic Friction Calculations.
 

Step by Step Calculation

Back to Top
Step 1 :  

Kinetic Friction Formula:

Kinetic Friction: Fk = μk×N
Kinetic Friction Coefficient: μk = Fk/N
Normal Force: N = Fkk
Where,
μk = Kinetic Friction Coefficient,
N = Normal Force.



Step 2 :  

State the equation you plan to use and plug in the values.



Example Problems

  1. A mass is resting on a flat surface which has a normal force of 92N, with a coefficient of kinetic friction of 0.34. Calculate the  force that it would take to move the object?


    Step 1 :  

    Given that:
    Normal force(N) = 92N
    Kinetic friction coefficient(μk) = 0.34
    Kinetic Friction(Fk) = ?


     



    Step 2 :  

    Substitue the given values in the formula:


    Kinetic Friction: Fk = μk×N


    Fk = 0.34×92


    Fk = 31.28N



    Answer  :  

    Fk = 31.28N



  2. A 38kg piece of wood is placed on top of another piece of wood. There is 58N of kinetic friction measured between them. Calculate the coefficient of kinetic friction between the two pieces of wood?


    Step 1 :  

    Given that:
    Normal force(N) = 38kg×9.81m/s2 = 372.78N
    Kinetic Friction(Fk) = 58N
    Kinetic friction coefficient(μk) = ?


     



    Step 2 :  

    Substitue the given values in the formula:
    Static Friction Coefficient: μk = Fk/N
    μk = 58/372.78
    μk = 0.156



    Answer  :  

    μk = 0.156
