The Whirl Around By: Adria O’Neal Andre Merino Brett Stroube Introduction Our project’s goal was to make a rollercoaster that would run for up to 15 seconds. Our ball was already supplied thanks to the fall engineering fair. The tape and box were items we already had. But we had to buy the wooden dowels. Other expenses were the cost of knife, glue, and construction paper for the track. Overview Our first step is to release a ball from the highest point down a series of ramps. Then it lands in a cup at the end of ride. There are pieces of tape attached to the track to create friction so ball can run without to traveling too fast. There is also a little door attached to one of the sides. There is a drop at the end that releases the ball to the cup. Stored Energy As you know the main two energies that occur are Kinetic and Potential Energy due to gravity. There is also some friction forces applied to ride which causes some energy to be loss. Conclusions The building of the project took 5 hours of work by all three team members. Original design was not as easy to apply. We encountered some problems including: The loop was not constructed due to the lack of right material and fear that we did not have the velocity to get ball through loop. Time trials were constantly varying. We are glad we ended up with a final product!!!!
