More fun than a barrel of static friction

by Janie Jones

In physics we are “studying” friction.  Or at least other people are studying it, I’m trying to survive it.  But, I have it on good authority that static fiction is fµN.

Physics teacher tells us this is true because the maximum static frictional force (fs, max) is equal to the coefficient of static friction (μs) times the normal force (N).  Written as an equation you then get:

Oh yes, what fµN indeed.  Happy Friday.
