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
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

issues problems
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
