Roller Coasters!

Tis week we talked about how gravitational potential energy is used to propel roller coasters through twists, turns, and loops.  In class, we made roller coasters using 3x5 cards.  We each had a potential energy "budget" that came from a ramp set at a fixed height.  If someone wanted to use more energy, they had to design a ride that went off the table to the ground.
