Hi, I am requiring some assistance in getting some clarification on frictional forces.
I know that Ff = u(Fn).
How do you generally find the frictional force though? I noticed how sometimes Ff is the same as the applied force, and sometimes you find it by using Fnet = Fa - Ff.
Why is this? And how do I know when to use which? Thank you!
