GRAVITY2.ZIP    Simulates motions of planetary bodies in space

Obtained from a local BBS.

Gravity v2.0 is a powerful tool designed to simulate the motions of
planetary bodies in space.  You may specify the following parameters for
up to 16 bodies:  Mass, Density, Initial position, and Initial velocity.
The bodies are then plotted as they move according to the laws of
gravitation.  You can view any location in space at any magnification.
You can also watch the motion of a single planet via a "tracking"
feature.  Set up systems and play "what if..."  Elapsed time is
optionally displayed, and nearly every variable is available for user
adjustment.

Equipment Required:
  IBM compatible personal computer
  Graphics display (Hercules, CGA, EGA, VGA, At&t, 8514/a)
  Disk drive (Floppy or Hard)
  At least 384K free memory after boot-up (640K recommended)
  80x87 math coprocessor greatly increases speed of running simulations.

me any questions about orbital mechanics, quantum physics, etc.
