Fn=mat T1-T2=max T1-T2-mg=may N1-w=may t-f=max -n2=may f-T=ma n1-n2=ma n1-w=ma

f-w/m a=Fn/m a=m2* g/m2+m1 The coefficient of friction is a number that reps how two surfaces interact when you try to slide them across each other it is a ratio it has NO units coefficient of friction does not depend on mass friction, friction and force are proportionally increased
