   The parameters below the gray bar are constants provided for your benefit.  They may not be changed without altering the calculation scripts attached to the card.
  The parameters listed above the bar are variable.    To change any of them, drag across the box holding the value and type the new value.  Pressing <return> will automatically select the value in the next field.
   Any change in the controlled parameters will be reflected as a change in the outcome of the experiment.  Feel free to play around.  
   Try these parameters:
      Cart Speed:       90        180         180
      Drop Height:      20        20           10
