3. Overview Dimensions 0.5m x0.5mx0.5m Set up: 30 seconds Duration :15 seconds Object: lead ball and ball bearing Begin coaster by hand The rollercoaster starts off inside a spiral with the ball bearing. At the end of the spiral the ball bearing hits the lead ball causing it to fall into a PVC pipe leading to a loop. The lead ball goes up a curved incline and falls into a funnel. It then gradually rolls through a PVC pipe ending in a landing pad.

4. Equations  PE = KE + Eloss  Energy: mgh=1/2mv^2+Eloss  Ex: On roller coaster when ball bearing is released  Conservation of Momentum  P1 + P2 = P1’ + P2’  Ex: On roller coaster when ball bearing hits lead ball

5. Cost  Pipe Insulation: $1.00  Plywood & wooden dowels: $10.00  FUNnel: $1.00  50 caliber muzzleloader lead shot: $2.00  Ballbearing, PVC: $1.50  Clear Tubing: $8.50  Total Cost: $24.00

6. Fun facts  Length of time on project: 7 hours  Total work and planning: 9 hours  Adversity:  Planned roller coaster differed greatly from actual roller coaster  Friction was a momentum killer (haha) literally and figuratively
