  2. Our design includes a zig-zag on an inclined plane at the beginning, a square spiral as it descends the track, a small loop, a jump, and ends in Pacman’s mouth. Overview of Design

  3. Energy in Device • Potential energy at the top of the zig-zag • Kinetic energy during the length of the coaster Forces at Work • Friction • Gravity

  4. Design and Construction Issues Materials Used • Working with clay • Constructing the loop • Having enough energy for jump after the loop • Lack of mass in the marble • Variation in materials due to temperature • Accuracy of tools • Consistency of materials • External factors • Clay • Scrap wood • ¾ inch hose tubing • Tennis ball • Marble • Paper • String • Molding strips • Nails • Staples

  5. Conclusion • When designing a roller coaster, forces that are normally ignored in concept questions need to be considered. Drag, air resistance, friction, and mass were all factored in to our coaster. Although the project was enjoyable, we had to apply all we learned in Engineering Fundamentals.
