F = J/Δt during the pulse; J = 1

Unit-mass, unit-frequency oscillator initially at rest, driven by one rectangular force pulse with fixed external impulse J = 1. Restoring forces act during the pulse, so residual energy depends on duration.

What this model assumes

Unit-mass, unit-frequency oscillator initially at rest, driven by one rectangular force pulse with fixed external impulse J = 1. Restoring forces act during the pulse, so residual energy depends on duration.

How to explore it

Begin with the default values. Change one control at a time and watch both the graph and the readouts. Then reset the model and change another parameter. This isolates which input produces the effect you are seeing.

The plotted values are generated from the displayed equation. Downloading the calculated data lets you inspect the numerical series or compare it with a calculation of your own. The data are synthetic model outputs, not observations from an apparatus.

Before carrying a prediction into an experiment, match the model’s assumptions to the actual system: the relevant degrees of freedom, boundary conditions, noise, losses and measurement convention. The linked articles explain which comparison is physically meaningful.
