Physics Simulations 1.3 is considered as a flexible and effective physics teaching software, which brings the information and computer technologies right where they are mostly needed--in school. The project unlocks the power of ICT to simulate processes with animation and calculate complicated quantities and uses it to ease the education in the school subject whom they used to determine with one word--complicated--the physics.
Requirements: Windows 95/98/Me/NT/2000/XP

Caerfai Chemical Simulation 1.0
Caerfai Chemical Simulation is a simple tool that is trying to simulate chemical reactions more>>
The model is much too simple to be useful, but it gives some nice images and animations. Source is included and offers a nice starting point for similar endevours.
Every atom in the simulation is a moving ball which bounces on other atoms and the edges of the window. Atoms can bind to each other, similar to how things work in reality. Well start out with just radicals and build molecules from there. In reality, this is pretty much where it stops, but I break up the molecules everytime they bounce, in order to create more interesting structures. Less chemical, but more fun.
Breaking up the molecules when in reality they would break, would complicate the program a lot beyond the current few hundred lines and anyway, the reaction would occur almost never, as it happens in reality (but there the molecules go so fast that it seems quite quickly, especially if your sleeves have gotten on fire)

It is relatively straightforward to write down the Equations of Motion for this system using the formula for the acceleration of a particle in Cylindrical Polar co-ordinates. If the parameters you choose are too drastic, this model goes spectacularly haywire.
