Everybody Dance Now Roller Coaster
We are team C. & C. Music Factory formerly team Mustang. This is our roller coaster – Everybody Dance Now. Our project is named after the person in the library whose ringer was the song Everybody Dance Now.

3. Overview Elevator lifts ball to top of the track
Balls falls 2.5 inches to track
Rolls down a 12.5 inch board at 3 degrees below horizontal
Repeats seven times
Drops from a height of 10 inches
Our rollercoaster starts with a electric motor that is powered by 2 “AA” sized batteries. The motor is able to lift the ball up inches in approximately 5 seconds. Once it reaches the top, it falls 2.5 inches down to the track. Once on the track, it rolls down at a grade of 5.24% (or 3 degrees) for 12.5 inches. This process repeats itself seven times to create a zigzag effect. After the ball is done zigzagging, it reaches the final section, a 10 inch drop to a catch.

End of Drop to Catch
Initially, the roller coaster obtains its energy from the electric motor which puts work into the system. Once the ball reaches the top of the lift, all of its energy is gravitational potential energy. Once it reaches the peak, it drops from the apex to the track. During this transition, the energy is changing from gravitational potential energy to kinetic energy, but remains largely gravitational potential energy. Next the ball travels down the zigzag path. While on the track, the energy is shifting from gravitational potential energy to kinetic energy, but still remains mostly gravitational potential energy. After the ball finishes zigzagging, it drops to the catch. At this point, the energy is transforming from gravitational potential energy to kinetic energy, but now is primarily kinetic energy. At the instant before the ball hits the catch, it is all kinetic energy.

5. Conclusion Estimated Cost: $33 Project took 7 hours to build Problems
Metal wire welded to supports
Ball does not fit into piping
Magnets didn’t stay attached to belt
Estimated Cost: $33
Our project took 7 hours to build. While constructing it we ran into some obstacles. We had originally planned to construct the track with metal wires welded to supports. This proved to be exceptionally time consuming. Then, we tried using pipes for the track, but the ball would not be fit in the pipe. Consequently, we had to go to our third option, which is a wood track with ruts routed into it. The magnets that take the ball to the top of the lift were too strong and detached from the belt when the ball reached the top. To correct this dilemma we super-glued the magnet to the belt. We estimated the cost to be roughly $33.
