After our assessment on momentum and projectiles, we whiteboarded some questions about circular motion. The biggest thing that seemed to trip us up was whether the force that pushes you in a circle is another force that should be drawn on the force diagram or a force we already know from our interaction diagram. We also had a great discussion about how much kinetic energy and potential energy you have to give a satellite to get it into orbit. (This is another reason I'm happy I postponed circular motion & projectiles until after energy & momentum.) We ended by talking about the forces on banked curves. We did it just qualitatively, but there were many, many questions about it.
