Device Design We included an elevator that uses potential energy, Which then leads into a series of switch backs, Which uses gravity to accelerate the ball. Then leads into a series of spirals, And ends with a big splash!

Energy Summary Point 3 KE + PE = KE + PE Kinetic Energy at point 3.332J Velocity at point m/s Potential Energy at point J Point 2 KE +PE = KE + PE Kinetic Energy at Point 2.287J Velocity at point m/s Potential Energy at point.117J Point 4 KE + PE = KE+ PE Kinetic Energy.4035J Final Velocity 7.879m/s Potential Energy 0J Point 1 PE = KE + PE Kinetic Energy 0 Potential Energy.4035J Initial position- ball is at rest and weight supplies potential energy to get it started.

Design/Construction Issues Original design was much too simple lacked length required to fill 15 seconds Began with only PVC pipe, but it did not take enough time and could not curve, also joints caused the ball to stop. We added clear hose, but the ball continued to get stuck in it so we replaced it with foam tubing that the ball rolled through better. After we came up with a good design that worked, we struggled to make it last 15 seconds while still remaining interesting. We feel these set backs helped us to problem solve and create a successful rollercoaster.

Conclusion In conclusion Team Patrick succeeded in building a roller coaster that transports a marble from point A to point B in as near to 15 seconds as possible. Over the course of the project Team Patrick was able to overcome many unexpected obstacles. Some of the obstacles included too simple a design, material flaws, and design flaws. However, by overcoming these obstacles we feel that it has made for a better rollercoster
