Materials A large and small marble Boxes Clear Tube Duct Tape 11.3 kg weight Phone books Book Screws Mail Tube Alarm clock Pencil Thumbtacks Frame Plexiglass Pink Twine

Energy Used Gravitational potential energy- mgh Kinetic Energy- ½ mv 2 Rotational Kinetic Energy- ½ Iω 2 Center of Mass-Σmr/Σm Torque- Στ=Iα Projectile motion- Conservation of Momentum- m(Δv)=m(Δv)

Design and Construction Issues Takes time to set/reset Goes off by itself (sensitivity) Structure is unstable Level of the floor is important Kink in the hose

Conclusions Sometimes fails in various locations Original designs- nothing like the final design
