Ejs Intro SpringLab Model
written by Anne Cox, Wolfgang Christian, and Mario Belloni
supported by the National Science Foundation
The Introductory Spring Lab model asks students to develop a model for a mass on a spring. It is distributed as a ready-to-run (compiled) Java archive. Double-clicking the ejs_intro_SpringLab.jar file will run the program if Java is installed. In order to modify this simulation (and see how it is 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:
The Intro Spring Lab program is one of a suite of Easy Java Simulations (Ejs) models used in Introductory Physics Labs. Ejs, a part of the Open Source Physics Project, and is designed to make it easier to access, modify and generate computer models. Additional models can be found by searching ComPADRE for Ejs.
Please note that this resource requires at least version 1.5 of Java.
3 supplemental documents are available
Ejs Intro SpringLab Documentation
A pdf document that briefly describes the Ejs Intro SpringLab model. It describes how to use the stp_intro_SpringLab.jar file with Ejs and contains associated laboratory exercises and instructors notes.

A modification of the EJS spring lab that allows students to load experimental data (y vs t and v vs t) into EJS in order to compare experiment and theory data on the same plot. This zip archive contains the EJS file, a PDF of the experiment description, and a text file containing example data.
