  2. Overview • Steps • Pulley systems • Inclines • Track • Mousetrap • Applied concepts • Conservation of momentum and energy • Torque • Projectile motion

  3. Operation Golf ball rolls down inclines Runs off ramp into funnel Ball falls into cup which pulls white cup and releases marble

  4. Operation Mousetrap triggers pulley which raises flag Marble falls onto track and triggers mousetrap Pulley releases marble to group 7

  5. Calculations Subscripts: 1 golf ball 2 cup & marbles p pulley • Step I: The Decline. • Conservation of linear/rotational energy: m₁gh=½m₁v ₁ ²+½I ₁ ω ₁ ² • Step II: The Pulley. • Torque (about pulley): τ=Iα=I • Conservation of momentum (inelastic collision): m₁v ₁+ m₂v₂=(m ₁+ m₂)v’ • Step III: The Curved Decline & Funnel. • Conservation of energy: mgh=½mv² • Step IV: The Track & Mousetrap. • Mousetrap and track—Conservation of energyand elastic potential energy • Step V: The Pulley & Flag. • Torque (about pulley) • Conservation of rotational energy

  6. Setbacks • Finding a ball heavy enough to execute the first pulley • Placing the cup in an accurate position for the golf ball to fall into. • Estimating the correct distance between the curved decline and the funnel in order to project a marble into the funnel • Setting a precise amount of tension in the string on the second pulley to raise the flag

  7. Summary • Factors that weren’t calculated affected movement of the project • Multiple test runs wore out certain parts of device • Simplicity is key
