For an object sliding at velocity v with a force of friction [tex]F[/tex] and a normal force [tex]Fn[/tex] , an equation that can be used to calculate the coefficient of kinetic friction [tex]\mu_k[/tex] is
[tex]\mu_k=\dfrac{F}{Fn}[/tex]
What is Kinetic friction?
It is a type of resistive force which comes to play when two contacting surfaces have relative motion with respect to each other.
in general, the coefficient of kinetic friction ([tex]\mu_k[/tex]) is slightly less than the coefficient of static friction([tex]\mu_s[/tex]).
The coefficient of kinetic friction is calculated by the mathematical expression
[tex]\mu_k=\dfrac{F}{Fn}[/tex]
