The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
static usully greater then kinetic
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.

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.
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
There are two types of friction : static friction and kinetic friction. Static friction occurs when two objects are touching but are not moving relative to each other. For example, static friction can prevent a box from sliding down a slope. The static friction between this box and the slope (and between any objects) can be calculated using the equation : Fs = µsN where µs is the coefficient of static friction and N is the normal force. Kinetic friction occurs when two objects are touching and moving relative to each other. For example, the kinetic friction slows down a box sliding down a slope. Also, when two surfaces rub together, there is kinetic friction. The kinetic friction can be calculated using the equation: Fk= µkN where µk is the coefficient of kinetic friction and N is the normal force.
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
