Rube Goldberg Machine: The most complex way to put a penny in a piggy bank

Created By: Gabby Bitton, Nick bergo, Bryan Blair, Emilie baxter

With Great thanks to Mr. Williams!!!

slide2

Wheel and axle hit cup of marbles

  • Kinetic Energy to Kinetic Energy:
  • Continuation of motion transferring energy from movement of objects
  • Example of wheel and axle
slide3

2. Marbles down screw

  • Find acceleration:
  • MA = distance of screw over distance of its height
  • Ag over Ma will equal the marble’s acceleration ( Ag = acceleration due to gravity)
slide4

3. Marbles hit jenga to release ball

  • Potential Energy to Kinetic Energy:
  • High position = pick up speed and momentum
  • Motion = energy to knock over book
slide5

4. Ball hits book to fall with lightweight

  • Mechanical Advantage:
  • Equals output force over input force
  • How hard or easy a machine makes an action
  • Pulley – circumference to lighten weight on each side
slide6

5. Heavy weight on other side drop on lever

  • Kinetic Energy to Potential Energy:
  • Force of weight on lever push stuck up high in position
  • Energy transfers to move up
  • Energy from previous motion
  • 1st class lever- effort to fulcrum to load
slide7

6. Lever goes up to push marble down screw

  • Potential Energy:
  • PE = 1/2 x mass x acceleration due to gravity x height
  • Energy gained from position
  • Lever gives force to move stick up
  • - Gives momentum to go faster
slide8

7. Marble hits golf ball

  • Kinetic Energy:
  • KE = ½ x mass x velocity squared
  • Chain reaction
  • Kinetic to kinetic:
  • - energy transferred object to object
  • - allow to move
  • - considered as impulse and momentum
slide9

8. Golf ball hits yellow stick

  • Work and Force:
  • W = force x distance
  • F = mass x acceleration
  • Picks up speed from inclined plane
  • force of motion from potential energy
  • - power (P=W/T)
  • \\
slide10

9. Pulley – Wall-up

  • Mechanical Advantage:
  • MA = input distance over output distance
  • For pulley, MA=# of ropes that are not downward pull rope
slide11

10. Penny goes into piggy bank

  • Acceleration:
  • A = change in velocity over change in time
  • Freefall acceleration = 9.8 meters per second squared
  • Incline planed allows less time and more speed
  • - increase acceleration
  • - why ramps for snowboarders
