Force of Friction
@Chestermiller, yes I know all that. sadly I have two unknowns and only one equation. I want to find the coefficient of friction but all I have is the normal force, I don't know the total amount of the force of friction being applied.
@Doc Al, That will work but depending on the masses I accuracy of the masses I am using I will end up with a big error percentage. Is there any any way to reduce the error. I should have mentioned this in my first post but I am trying to do this experimentally. The smallest mass I will have access to is 1 gram.
