Semester 2 – Day 10


Clearly the students are getting some idea of what the Normal Force is. h
However, as in so many years before they assume the normal Force can only exist on objects on contact with the ground. i’m also concerned that students do not fully grasp the relationship between the coefficient of static friction, the normal force, and the maximum static friction possible on an object.

I’m going to have them do some more problems and present out on whiteboards. It’s been awhile since I’ve done this, and I hope that a fresh approach will be effective.
