Today we worked on problem solving with the Central Force Particle Model (CFPM). I really, really like force vector addition diagrams (FADs) here, as after a week of qualitative analysis kids understand that if the motion is uniform, then the net force should be towards the center, so the FAD helps them get the direction of the force(s) causing the centripetal force correct. Also, I have really been enjoying doing mini-board meetings for problem solving whiteboarding, as this group is doing.
