  1. THE “MOVE IT” MACHINE Presented by…… Josh Elliott Shanel Crawford-Harris Weston Iler Breana Harvell

  2. The “Move It” Machine How does it work??? • Marble is blown through the angular tubing • Marble collides w/ the golf ball causing it to • roll • Golf ball rolls down two ramps & falls into • the teeter-totter • The ball weighs down the tetter-totter • causing it to flip 90° to the right, releasing • the tetter-totter holder, and weighing down • the wood • The battery sitting on top of the wood is the • counterweight needed to hold the spool in • place • The wood then releases the spool and • allows king Julian, in the netting, to stop the • “MOVE IT” song on the laptop

  3. Summary of Energy & Equations • Conservation of energy ½ Ι ωi2 + mg hi + ½ m vi2 = ½ Ι ωf2 + mghf+ ½ m vf2 • Elastic Collision m1 v1 i+ m2 v2i = m1 v1f + m2 v2f • Torque ΣΤ = Ια = m r2 α

  4. Issues/ Problems Size and shape of the tubing  lead to problems w/ marble transportation Surface and weight of the wooden balance  w/o sand paper and a D battery, it would not hold the spool in place Weight of King Julian and platform  he needed more weight and a wider platform in order to hit the key on the laptop

  5. Conclusion • Concepts Used • Torque • Angular Momentum • Center of Mass • Conservation of Energy • Collision
