Gravity makes a projectile fall toward the earth while in flight. The projectile's size, shape, and the air density affect the speed by which it travels. Air resistance slows the speed of a bullet and reduces the distance by which it travels. The velocity of a bullet is given in feet per second (fps) in the United States.
