Today you had the challenge to design and build roller coasters with pipe insulation, tape, and marbles.  You have to consider what KE is and how you get it, and what PE is and how you get it.  You had to think of the forces on your marble in every direction as it travels down your track and maneuvers through your features.  We’ll do the same tomorrow.  You’ll be able to think and work even more on the impressive start you got today.
