Computer Program Detail Page

Item Picture
written by Andrew Duffy
In this simulation, students investigate the electric field at various points along a line. They can activate one or two charged particles and set the charge from -30 to 30 nC.  A graph showing the electric field as a function of position may be viewed or hidden. Net electric field is calculated at the bottom of the screen.  

This applet was created with EJS, Easy Java Simulations, a modeling tool that allows users without formal programming experience to generate computer models and simulations.

11. Common Themes

11B. Models
  • 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.
  • 4G (9-12) #4.  Different kinds of materials respond differently to electric forces. In conducting materials such as metals, electric charges flow easily, whereas in insulating materials such as glass, they can move hardly at all. At very low temperatures, some materials become superconductors and offer no resistance to the flow of current. In between these extremes, semiconducting materials differ greatly in how well they conduct, depending on their exact composition.

11. COMMON THEMES

B. Models
  • 11B (9-12) #1.  The basic idea of mathematical modeling is to find a mathematical relationship that behaves in the same ways as the objects or processes under investigation. A mathematical model may give insight about how something really works or may fit observations very well without any intuitive meaning.
