Whip Motion

I am trying to simulate motion with a whip controlled by the mouse. Anyone have any ideas on this?

Check the spring-builder movie on my website:

Spring Builder

Press the 'clear' button and then create a series of connected points. Then hit the 'simulate' button and drag the red point around. Turn off the button that says 'draw curvy' and increase air resistance.

This technique of connecting points with springs works for things like whips, ropes, etc.
