Projectile Motion Simulator
Video: http://www.youtube.com/watch?v=Taj2-XdooiY&feature=plcp
Hi everyone, I recently finished my first “real” computer program, and wanted to share it.
It is a realtime projectile motion simulator and grapher that also includes a representation of air drag that you can compare to an “ideal” projectile path (no air resistance). The ideal path has been tested to be correct. I couldn’t find a free simulator with air drag where you could edit fields about the object, but I think it is also correct in a very simplistic sense. In reality, other factors such as lift and wind can lead to different flight paths.
You are free to share it if you find it useful, just obviously not free to sell it. I want this program to stay free and help people out with understanding projectiles better.
SIMULATOR DOWNLOAD LINKS:

If the above didn’t work you may be running an older version of Java. Try this instead:

HOW TO RUN:
If the program doesn’t open with a double click you can do one of two things. You can download Jarfix which should take care of everything (worked for me). Be careful to avoid downloading the extra toolbar and such as this is free add supported software.

If you are worried about downloading Jarfix, you can also use the command line. I personally suggest Jarfix as it was easy to run, and immediately fixed the issue.
KNOWN ISSUES
~Though I tried to limit "crazy” value inputs while allowing you to still experiment, some combinations of numbers can cause odd glitches because the object is modeled to slow down faster than the “refresh rate” of the simulation can allow.
~If the object moves 0 meters, you have to press manually stop the simulation.
