Team Our Rollercoaster (Beautiful Isn’t it?)

Introduction Problem Construct a ‘Roller Coaster’ with a runtime of around 15 seconds. Materials Vinyl Tubing PVC pipe Wood Lots of duct tape Buisness Cards Two Liter bottles Expenses Vinyl Tubing 10$ Beads 1$ Wood 5$ Pegboard 7$

Project Run ‘Car’ (ball) runs down vinyl tubing along two liter path. Drops onto wood ‘stairs’ and through other pieces of tubing. Shoots out of final tubing at bottom Forces and Energy Tubing Ball transfers some of its potential to kinetic energy Wood Ramps Potential to kinetic energy Frequent collisions

Conclusions Construction took around 3-4 hours We encountered some problems during our experiment such as finding a perfectly spherical object to use as our roller coaster that would fit through out design and random design issues.
