Rotating Space Station Gravitational Physics Simulation by WolfKeeper

Notes:

1. If you're having problems running the applet in IE (often you have a grey box), check that you have: a) downloaded the java 2 plugin from Sun, b) enabled Java c) rebooted
2. Space station has 200m radius (328 feet)
   
3. Station rotates about once every 20 seconds
4. Interior 'surface gravity' is 1g
   
5. The station has recently been depressurised for maintenance, so the objects motions are unaffected by air drag
6. If you have lots of trails on the screen at once, the program may start to run slowly (depending on machine speed), clearing the trails by double toggling the 'trails' button or pushing the 'clear' button regains full speed
   

Fun things to try/work out:

1. fire objects with and without the external view flag set, it looks very different, can they really be the same?
   
2. Put an object into a perpetual orbit (hint: set the angle to 90 degrees and fiddle with the speed). Try doing this from different heights. What is the relationship between the height and the firing speed to achieve this? (Try pushing the external view flag.)
3. try to arrange for an object to return right past the gun without encircling the center of the habitat.
4. try to arrange for an object to return right past the gun after encircling the center of the habitat.
5. try to arrange for an object to return right past the gun and go right through the center of the habitat on the way.
