The driven harmonic oscillator is a standard physics model and the Driven Simple Harmonic Oscillator Comparison JavaScript Model displays 51 such oscillators with different natural frequencies.  The oscillator mass increases from left to right in the display and the oscillator in the center of the display has a mass of one and is in resonance with the driving frequency.  All 51 oscillator differential equations are solved simultaneously but the motion or each oscillator is independent of the others because these equations are uncoupled.

The Driven Simple Harmonic Oscillator Comparison JavaScript Model was developed using the Easy Java/JavaScript Simulations (EjsS) version 5.  It is distributed as a ready-to-run html page and requires only a browser with JavaScript support.  This model runs on tablets.
