The Ejs Damped Driven Simple Harmonic Oscillator model displays the dynamics of a ball attached to an ideal spring with a damping force and a sinusoidal driving force. The spring is initially unstretched and the ball has zero initial velocity. The initial position of the ball can be changed by clickdragging the ball when the simulation is paused. You can modify this simulation if you have Ejs installed by rightclicking within the plot and selecting "Open Ejs Model" from the popup menu item. <br /><br />Ejs Damped Driven Simple Harmonic Oscillator model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a readytorun (compiled) Java archive. Double clicking the ejs_osc_SHODriven.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for Newtonian mechanics are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.
