EJS Mechanics Package: Challenging Intro Physics Topics 

written by Jen Trinh and Amy Bug

The EJS Mechanics Package: Challenging Intro Physics Topics contains Easy Java Simulations (Ejs) models used in a high-level Introductory Physics course for physics majors. The topics include vector kinematics in polar coordinates and linear momentum with rockets. Ejs, a part of the Open Source Physics Project, is designed to make it easier to access, modify and generate computer models. It is distributed as a ready-to-run (compiled) Java archive.  Double-clicking the ejs_mechanics_sampler_klepner_kolenkow.jar file will run the program if Java is installed.

In order to modify the simulations (and see how they are designed), if you have Ejs installed, you can right-click within the simulation window and select Open Ejs Model from the pop-up menu. Information about Ejs (Easy Java Simulations) is available at: http://www.um.es/fem/Ejs/.  Additional models can be found by searching ComPADRE for Ejs.
