I'm interested in finding out what the coefficient of friction would be for a few different materials such as:Copper on aluminum
Copper on graphite
graphite on aluminum
I'm not sure if it matters if the order is reversed such as Aluminum on copper vs copper on aluminum..
also I've seen that there is a difference between static and kinetic which I'm not sure what the difference is - obviously kinetic means moving but I'm not sure which I'd need b/c the material will be static until it starts moving - then it will speed up and I'm trying to calculate how quickly it may speed up with respect to the friction & energy input. This page shows how much difference there is between some static and kinetic coefficients - http://www.physlink.com/Reference/FrictionCoefficients.cfm
This page gives a lot of values for static friction but it doesn't have the ones I listed above - http://www.engineeringtoolbox.com/friction-coefficients-d_778.html

Is there any way I can find out either static or kinetic of those I listed?
