Ejs Intro Mechanics Lab Package
written by Anne Cox, Wolfgang Christian, and Mario Belloni
educational validator: Jacob Brock
The Introductory Physics Lab package contains Easy Java Simulations (Ejs) models used in Introductory Physics Laboratories which ask students to develop a series of models for simple mechanical systems. 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_intro_lab.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 (including independent copies of each of the exercises contained in this package) can be found by searching ComPADRE for Ejs.

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