Virtual Basketball 1.3 for Win 9x/NT/2k
is a true-motion basketball match simulator
===========================================

Virtual Basketball is a true-motion match simulator designed 
for learners with an interest in physics. It models ball 
movements under varying physical conditions. Virtual are a 
team's changing gravity and ball friction caused by e.g. wind. 
As in reality, the motion and result of each shot are computed 
according to the laws of gravity and friction. 

Two teams, Red-City Bulls and Blue-City Lakers, are
competing against each other, attacking and defending.
The defending team uses the Tab and Arrow keys of the
keyboard and changes its gravity vector and ball friction
with Arrow_LEFT = ++40 units, Arrow_RIGHT = --40 units, 
     Arrow_UP   = ++1  unit,  Arrow_DOWN  = --1  unit,
resulting in a different ball motion.

The attacking team uses the mouse to shoot balls by: 
1) pressing the left mouse button on the court marking the
   position of a player,
2) keeping (!) the button down, moving to another position
   and releasing it giving the ball's speed and direction.

As in reality, the motion and result of each shot are
computed according to the laws of gravity and friction, 
and visually displayed on the computer screen.

After one team has scored, its gravity vector and ball
friction are randomly changed (or manually by the other team)
so that it becomes much harder to score again. This is the
easy way to play the game. The difficult way is to allow
the defending team to change its gravity and friction 
values all the time.

The statistics of both teams, their number of scores and
tries as well as the average distances of all shots are
automatically recorded and displayed in another window.

The goal of this program is to teach a user to understand better

1) how the motion of a ball depends on its position, direction,
   speed, and friction,
2) how the laws of gravity and friction (the acting forces) 
   effect the movement of a flying object, 
3) how motion and forces are interrelated, and
4) how to predict the motion of an object (see the Appendix 
   in the Help file for further information).

The program is designed for all learners with an interest in physics.

Virtual Basketball can be downloaded at (1.3 MB)
http://bsttc.marhost.com

To install Virtual Basketball for Windows,
do the following:

1) Create a temporary folder e.g.'C:\Temp'
2) Unzip the 'VirtualBasketball.zip' file into this folder
    (if you don't have a zip program, a free download
     is available at http://www.winzip.com)
3) Run 'Setup' and follow the instructions
4) After the installation is successfully completed,
	you can run or uninstall Virtual Basketball
	like any other Windows program.

If needed, the unzipped installation files can be copied
to one 1.4 MB floppy diskette. Then insert it into the
floppy drive and run 'Setup' as described above.

To uninstall Virtual Basketball use the Windows 
desktop by clicking Start / Settings / Control Panel /
Add/Remove Programs. Then you get a list of installed
programs. Select e.g. Virtual Basketball 1.3, press the
Add/Remove button, and follow the instructions.

Virtual Basketball is shareware for $ 5.00 (1 user license)
