Friction Calculator
Top
When two bodies are in contact with each other a resistive force comes into play that slows down the motion. This is called friction.
Friction
Friction Calculator is used to find the friction between any 2 surfaces.
 

Step by Step Calculation

Back to Top
Step 1 :  

Friction Formula:




Friction: F = $\mu$ * N



Friction Coefficient: $\mu$ = $\frac{F}{N}$



Normal Force: N = $\frac{F}{\mu}$



Where,


F = frictional force



$\mu$ = friction coefficient,



N = Normal Force.



Step 2 :  

Put the values in the formula and calculate it further.

  1. Calculate the frictional force between two metal surfaces if its friction coefficient is 0.5 and it is having the mass of 15 kg?


    Step 1 :  

    Given: m = 15



    $\mu$ = 0.5



    The Normal force is given by



    Normal force = mg



    = 15 $\times$ 9.8



    = 147 N


     


    Friction Formula:




    Friction: F = $\mu$ * N



    Step 2 :  

    Put the values in the formula and calculate it further.


     


    F = $\mu$ * N



    = 0.5 $\times$ 147



    = 73.5 N



    Answer  :  

    Frictional Force = 73.5 N



  2. A person is pulling a box filled with loads is having mass of 120 kg and frictional force is 1000 N. Calculate frictional coefficient between box and floor.


    Step 1 :  

    Given: m = 120 kg




    N = mg




    = 120 * 9.8




    = 1176 N


     


    Formula:


     


    $\mu$ = $\frac{F}{N}$



    Step 2 :  

    Put the values in the formula and calculate it further.


     


    $\mu$ = $\frac{1000}{1176}$


     


    Friction Coefficient = 0.8503 N



    Answer  :  

    Friction Coefficient = 0.8503 N
