Week of 2/19

This past week I had three students come in to office hours on Friday. We discussed the topics of work and energy, specifically the conservation of mechanical energy when there are nonconservative forces acting on the system. The students seemed to really understand the topic after working through the homework question about a roller coaster and its energy and velocity at different points of the ride. It helped them understand the topic from a macro perspective. We also discussed the topic of work and its relation to the change in kinetic energy, solving problems for velocity of different objects.
