Rotation is absolute, linear motion is relative?

[QUOTE="jbriggs444, post: 6841614, member: 422467"] Naval gunnery officers can tell that the Earth is rotating. See pages 449, 450, 451 and 452 in [URL='https://www.eugeneleeslover.com/USNAVY/FC-APPENDIX-B-8IN-55.html']this document[/URL]. This is the "Naval Ordnance and Gunnery, Volume 2, Appendix B, Part 2: Extracts from the range table for the 8"/55 gun" for the U.S. Navy. The 8"/55 was a common gun on U.S. heavy cruisers in WWII. Coriolis has an effect on both deflection (pages 451 and 452) and on range (pages 449 and 450). This is the "toss a ball on a carousel" method, scaled up to larger and more explosive objects flung faster and farther on a more slowly rotating platform where the rotation is not always in the horizontal plane. Then too, [URL='https://en.wikipedia.org/wiki/Foucault_pendulum']Foucault[/URL] had an idea. [URL='https://en.wikipedia.org/wiki/Coriolis_force#Laboratory_testing_of_draining_water_under_atypical_conditions']Wikipedia[/URL] shows successful experiments under laboratory conditions with draining sinks. In addition, there are hurricanes, prevailing westerlies, trade winds and preferred rotation directions for high and low pressure systems. [URL='https://www.youtube.com/watch?v=UGRdsNe7skQ']The Simpsons[/URL] had a rather more humorous take on it. Rumor [apparently false] has it that the U.K. navy suffered in the Falklands (the 1914 battle, not the 1982 conflict) from not reading the fine print in their gunnery tables. See the bottoms of pages 451 and 452 for the notes about the southern hemisphere. [/QUOTE]
