When you shoot a bullet to the east, it's different than you shoot it to the west. Why? Simple answer, because the earth is spinning. But that effect is so minimal, we have to ask the real pros of Long-range snipers to tell us about the effect. The earth is spinning from west to east . When you shoot a target over 1000 yards to the west, the bullet leaving the barrel is no longer attach to the spinning of the earth. The target on the other hand, is still attached to the earth's spinning which is moving toward the shooter. Because of the curvature of the earth, the target that far is also moving slightly upward. The result will be the bullet hitting slightly lower to the bull's-eye. When you shoot to the east, the opposite will occur. The bullet will be hitting slightly higher to the bull's-eye, because of the target moving away from the shooter and slightly downward. I will attach a YouTube video to show such effect. The only thing about the video is the Host mentioning such an effect as the Coriolis Effect which is not correct. Coriolis Effect is a whole different thing. He simply misuse the term. But the demonstration he did was correct, just needed a different name for it. Although the Coriolis Effect is a different effect , it can too help explaining why the earth is a sphere which I will get into in the future.
YouTube title: "Demonstrating how Coriolis effect bullet drop at 1000 yards"
By the way, how do I attached YouTube video here?
If the earth is flat what casts the curved shadow on the moon?
That's right, that is something I want to get into in the future too
