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.

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

DESIGN AND CONSTRUCTION

ISSUES

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

MATERIALS USED

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.
