Then how does it ever rise above the level of the muzzle? “Fall” implies a negative change in altitude. The rate of vertical acceleration decreases at 32ft/sec/sec, but it doesn’t immediately fall out of the barrel. As long as the rate of upward acceleration exceeds 32ft/sec/sec the bullet will rise, at least while it’s near the earth.
