Simply click the button to view the drop.  This should work in all browsers except for IE 8 and earlier.

If the calculator has not been run for a few minutes the animation may not execute.  To do so simply refresh the
page.

A limited number of time steps are used in the solution.  For large drop heights, low damping and stiff springs the
drop response will be multiple low damped bounces and the animation will likely stop during a mid bounce.  For
smaller drop heights, moderate to high damping (>10%) and soft springs (fn < 10-20 Hz) the drop response will
be one to a few rebounds and the animation will likely stop at the static deflection of W/k
