   The fall (obviously) is an acceleration: you do not fall at a constant   
   speed.   
      
   If you fire a shot upwards, the projectile has an initial acceleration   
   upwards (in the barrel of the gun) but this initial movement no longer   
   has any influence when the projectile exits the barrel and is in free   
   fall.   
      
   In this last phase, the projectile "falls" (i.e. accelerates) always   
   downwards and never in another direction.
