Our Rollercoaster (Beautiful Isn’t it?)

3. 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$

4. 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

5. 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.
