The EJS Coulomb's Law and Electric Field Package is a collection of models for electrostatics. You can move charges around and see the force, observe the electric field generated by charge configurations and observe the motion of test particles in electric fields. Users can inspect and modify any simulation in the package if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.
The Coulomb's Law and Electric Field Package 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_electric_sampler.jar file will launch the package if Java is installed. Navigate within the package and click on a green triangle to run a particular simulation. 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 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).

Unfortunately, web browsers no longer support Java Applets so the ready to run applet pages pages will no longer work. You can, however, complete the exercises if you run the Java programs if you have Java installed on your computer. Download the jar file and double click on that file to run the Java program.
Apple users may need to lower your security setting to allow program from unidentified developers to run. Even then, you will need to right-click on the jar to authorize that program to run. This security feature on Apple computers only needs to be done the first time the program is run.
6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.

4. THE PHYSICAL SETTING
G. Forces of Nature
4G (9-12) #3. There are two kinds of charges?positive and negative. Like charges repel one another, opposite charges attract. In materials, there are almost exactly equal proportions of positive and negative charges, making the materials as a whole electrically neutral. Negative charges, being associated with electrons, are far more mobile in materials than positive charges are. A very small excess or deficit of negative charges in a material produces noticeable electric forces.
