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.

### AAAS Benchmark Alignments (2008 Version)

#### 4. The Physical Setting

4F. Motion
• 9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.

#### 11. Common Themes

11B. Models
• 6-8: 11B/M2. Mathematical models can be displayed on a computer and then modified to see what happens.
• 9-12: 11B/H3. The usefulness of a model can be tested by comparing its predictions to actual observations in the real world. But a close match does not necessarily mean that other models would not work equally well or better.
