>>if you were somewhere in the northern hemisphere, the points south of your are moving east at a slightly faster speed than you are, and points north of you are moving east slightly slower that you are. Does that make sense?<<
Wouldn’t my rifle’s muzzle be traveling east at a faster rate than my rifle’s chamber?
To some infinitesimal amount, possibly. It depends on how far the chamber is from the Earth rotation axis as compared to how far the muzzle was from the Earth rotation axis. I presume my post was fairly understandable and your question is just poking fun. But if not, let me know.
