Swinging Water cup demo picture

  • Demonstrate how centripetal force/acceleration keeps water
    in cup even when cup is upside down.
  • Place water cup on center of plate. Hold ropes such that
    plate is level. Swing slowly back and forth; when feeling ready, swing in
    full circle. Works very well. Practice once or twice before using in class.
  • Located in L02, section B2.
