  3. Energy Used • Gravitational potential energy- mgh • Kinetic Energy- ½ mv2 • Rotational Kinetic Energy- ½ Iω2 • Center of Mass-Σmr/Σm • Torque- Στ=Iα • Projectile motion- • Conservation of Momentum- m(Δv)=m(Δv)

  4. 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

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