The Ejs Wilberforce Pendulum model displays the dynamics of a Wilberforce pendulum in three dimensions.  A Wilberforce pendulum, named after its inventor, consists of a mass hanging from a spring such that the mass can oscillate up and down and also rotate. The pendulum is initially at its vertical equilibrium but the pendulum bob is initially rotated from equilibrium.  You can set the initial vertical position and initial angular position using the textboxes provided.  You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.  

Ejs Wilberforce Pendulum model was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_osc_WilberforcePendulum.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.

Please note that this resource requires at least version 1.5 of Java (JRE).
