Coefficient of Friction for pine on pine

AI Thread Summary
The kinetic coefficient of friction for pine on pine varies based on the specific physical characteristics of the wood samples, including their smoothness and moisture content. Accurate measurement for a specific setup is recommended for precise calculations. For theoretical purposes, a general value for wood on wood can be referenced from online resources. It's essential to consider these factors when conducting percent error calculations. Understanding these variables is crucial for accurate friction assessments.

Hey everyone,
Does anyone know what the kinetic coefficient of friction for pine on pine is? I am looking for the actual value in order to do some percent error calculations.
Thanks,

I think that would depend very much on the physical characteristics of your two pine samples. How smoothe they are, the moisture in the air... I think you'd have to measure the coefficient for your specific setup. If this is purely theoretical, you could probably use the value for wood on wood from this website:

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 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

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?
