					Whoopee for
Physics!!

Our Device




  Purpose: The purpose of this device is to
   deploy a whoopee cushion through the
   transferring of energy.
Oh, the Demonstration!!


  Please watch
       as we
  demonstrate our
      gadget!
Summary of Energy
Conversions
  1st Stage: Elastic Energy to Kinetic
Stage 2: Ball to Car




 Potential Energy to Kinetic Energy
Stage 3: Bowling Ball to
End of Ramp.
Potential Energy to
Kinetic Energy.
Stage 4: Bowling Ball drop
to Whoopee Cushion.
Kinetic Energy +
Potential Energy
to Energy needed
to depress
whoopee cushion.




(Broken into two
steps for
calculation.)
Conclusions

  As expected, energy was lost through
   friction
  We were successful in building our
   device
  We learned the virtues of teamwork
  We would have spent more time building
   the device so it would be more
   aesthetically pleasing.
