The Path of a Bullet
Air Resistance: The trajectory of a bullet is the path it takes from the time it leaves the muzzle of the gun until it reaches the target. As the bullet leaves the muzzle of the gun and meets the head-on resistance of the air, of course the latter tends to retard or hold it back in its flight. The amount of air resistance depends on the shape of the bullet, its cross-sectional area, and on its velocity; the density of the air also has a retarding influence in a small measure on the flight of a bullet, that is it tends to hold it back.
