Computer Simulations in Three Dimensions for Teaching Physics
 

Physics is the cornerstone of technological 
development. Training of physicists, engineers, and 
technologists is of prime importance to a modern 
industrial society. Computer simulations for the 
teaching of physics and technology are a quantum 
leap in the way the ideas of physics can be 
presented. A list of the simulations available for 
download is shown at the web site addresses:

All simulations are in three dimensions, and the 
axes can be rotated so that the trajectory or graph 
can be viewed from any direction. Dos versions and 
Windows 98 versions are available.  Each technology 
has its advantages and disadvantages. In the Dos 
versions the screen image can be sent to the printer 
(c:\graphics laserjetii (see the command format 
for the printer you are using)) and pushing the 
'print screen' key. In the Windows 98 versions the 
screen image is copied to the clipboard and then 
printed. LView software can also be used to capture 
the images. Acetates for overhead screen projection 
can be prepared from the screen dumps. The 
simulations can be used in several different 
teaching and learning environments:1.at home  2. on 
a computer lab network  3. in the class room with an 
overhead projector  4. on the internet. The programs 
are easily portable between the different teaching 
and learning environments. Exercise books with 
solved problems are available. The theory used in 
the simulations is briefly summarized in the theory 
section (Dos versions) and in the pull down window 
(Win 98 versions). All the Dos versions and Win 98 
versions of the programs can be downloaded from the 
internet. 


Once the basic format is developed all topics in 
physics and other areas of science in which models 
are required can be cast in this mold. All 
simulations have a theory section, a screen in which 
the simulation parameters can be selected, a screen 
in which the simulation takes place, and a screen 
where the simulation graph or trajectory can be 
rotated (In Win 98 versions the simulation screen 
and the rotation screen are the same).     


Computer simulations for the teaching of physics and 
technology are a quantum leap in the way the ideas 
of physics can be presented. Simulations animate 
physical theories and provide a bridge to the world 
of computer science which is so necessary in the 
modern work place. There is much work to be done in 
the area of simulations for teaching introductory 
physical concepts and these simulations presented 
here no doubt will provide the basis for continuing 
work.
