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
