The Team

IntroductionProblem Statement: Design and build a

device that will transfer either a cart or ball for a duration of about 15 seconds.

AKA a 15 second long rollercoaster

DesignBase

Made of PVC PipesWeighted down by sand bags

TrackClear plastic hoseFilled with blue waterSealed off by valves

“Cart”Ball bearing painted neon orange

DestinationPVC pipes taped to the floor

How it worksThe ball is released at the top of the hose and

continues down the tube until it reaches the end

Without the water, we tested it and it ran through in roughly 1.5 seconds

The water acts as a drag force to slow down the ball during the decent

Energy ConversionInitial Potential Energy = Final Kinetic

Energy + Energy Loss Due to WaterThe energy loss due to water is huge, which

makes the time difference with and without water so large
