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

Summary of Energy & Equations

• Conservation of energy

½ Ι ωi2 + m g hi + ½ m vi

2 = ½ Ι ωf2 + m g hf + ½ m vf

2

• Elastic Collision

m1 v1 i + m2 v2 i = m1 v1 f + m2 v2 f

• Torque

Σ Τ = Ι α = m r2 α

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
