Overview
Dimensions 0.5m x0.5mx0.5mSet up: 30 seconds
Duration :15 secondsObject: 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.

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

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
