Bullet Flight http://yogangsta.com/wp-content/uploads/2012/02/fast-bullet_1470_1280x800_wallpapercollection.net_1.jpg As the bullet leaves the barrel, the gases behind it are released, so there is no longer an acceleration pushing it forward toward its target. The only forces acting on the bullet during flight are the force of gravity and air resistance, a friction force, slowing it down. The rifling in the barrels of modern-day firearms gives the bullet angular momentum, which helps the bullet resist any changes in motion during its flight. This means that the bullet will continue to be accurate even with a strong wind, no matter what direction the wind is coming from.
