Point Charge Electric Field Demo Model
written by Wolfgang Christian
The Point Charge Electric Field Demo model shows the electric field with multiple point charge configurations and vector field visualizations.  Users can select these configurations from a drop down menu or can create their own configurations.

The Point Charge Electric Field Demo model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double click the ejs_em_PointChargeElectricFieldDemo.jar file to run the program if Java is installed.

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

If Field Lines can be added, it would a great visualization tool

i have always been very impressed by Physlets Electric field lines java applet
http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=734.0
the field lines is a concept continued to be explained in textbooks instead of the easily field vectors which is a common visualization in physics Ejs model.

chance to reproduce the field lines in this Ejs model? i believe it will be a great visualization tool.

AAAS Benchmark Alignments (2008 Version)

4. The Physical Setting

4G. Forces of Nature
  • 3-5: 4G/E3. Without touching them, an object that has been electrically charged pulls on all other uncharged objects and may either push or pull other charged objects.

AAAS Benchmark Alignments (1993 Version)

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.

changes made:
redesign the panel for control to be bottom
added more options to the menu for ease of use
made the drawing of charges proportional to the charges
made the collision detection to pause when the test charge is inside the charges
added evolution page to reflect the physics of motion
added test mass, m = 1 kg
added trail to show path of test charge that can be drag away and it will start from vx=vy=0
