Coefficient of Kinetic friction as a function of speed

AI Thread Summary
The coefficient of kinetic friction is generally considered to be independent of speed, despite the intuitive notion that friction increases with speed. The discussion highlights that increased friction felt at higher speeds is primarily due to air resistance rather than changes in the coefficient itself. Some participants seek literature to support this understanding, indicating a desire for deeper insights into the relationship between speed and friction. The consensus suggests that the material properties are the main determinants of kinetic friction. Overall, the conversation reinforces that while friction perception may vary with speed, the coefficient remains constant.

I'm modeling a moving cart, and I'm trying to determine if the coefficient of kinetic friction changes as a function of speed. Does anyone know of any literature where this is discussed, or if this happens? I would've thought friction solely depends on the types of materials used.

The coefficient of kinetic friction is independent of speed. This may seem counter-intuitive at first, because most objects clearly experience more friction as you push them faster. This is mostly due to increased air resistance.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
