The input includes the weight, drop height, spring constant, viscous damping value, gravitational constant and initial velocity if not zero.

The calculations include un-damped natural frequency of the weight on the spring, critical damping value, damping ratio, time to initial impact, maximum upward (-) direction acceleration, maximum downward (+) acceleration and maximum deflection after impact.

Several response cycles are charted. The charted response is limited to the pre-coded number of time steps which is dependent on the drop height and natural time period. A caution note is activated if the limit is exceeded. The results are still valid with the caution but the time response will have fewer than the normally charted number of response cycles.

The calculation does not require that the weight adheres to the spring/damper at impact and beyond and therefore can "bounce."

Any consistent set of dimensional units can be used that is consistent with Hz and seconds.

For no damping the the maximum displacement will match the theoretical value to within 1% where W/k=Δ

^{2}/2(h+Δ).

Future versions will address nonlinear springs, multiple degrees-of-freedom, non-viscous damper types and more.
