Questions for Discussion: Potential and Kinetic Energy: Spool Racer
In the video segment, what is the role of the rubber band? Why does it help make the spool racer go? Use the terms kinetic energy and potential energy to describe the spool racer. How would the spool racer's performance change if you put a pencil on each side? Can you suggest ways to make sure the race is fair? How might you redesign the spool racer if you were to build one? Why would you do that? What could you do to make the spool racer go faster?
