you might want to give them gravity
g = 9.806 m/s
1) gravity would not EVER be 9.806 m/s, it would be 9.806 m/s/s (m/s/s = metres per second squared)
2) gravity is not a constant
depending on where you are in the world gravity will be different, (mass and distance between two objects affect gravitational pull)
Gravitational pull can be determined with the universal gravitational law
F = G * m1 * m2
............r * r
this also means if the moon is above you gravity will be different
HOWEVER since it is such a minute difference, you can just use 9.8 m/s/s
someone took a course of planetary motion lol
Anyways but once again this doesnt effect the paintball or us as its simply so small it wont make any noticeable difference. Kind of like how the faster you move the slower time moves. or the closer you are to an objects center of gravity, and the larger that gravity is. time moves slower.
Or how if you shoot a paintball and you observe the paintball in flight for 3 seconds but the paintball might time the flight as 3.1 seconds.
and if we REALLY want to be anal crack heads, were only assuming that the physics we apply is for a euclidean flat space!
WERE fucked if spacetime is open or closed.
