The lack of difference in effect traveling in each direction & at different speeds along the variably rotating globe make it unbelievable to my logic & would require a huge leap of faith on my part to believe it. There are obvious standard answers to these questions, but they are unbelievable to my logic when I actually think about the supposed mega forces involved vs how everything actually calmly & universally works everywhere I’ve been on earth.
I like the video below more than the previous, if you want to see some autocad trig
When I was younger it felt like adults didn't grow older. I simply wasn't able to see it; the faces of my mother and my grandparents was after all the same every day, thus it was hard to accept that they hadn't always been like that, and that they eventually would grow older.
The same can be said about the effects of the spinning earth, they are there, but they are too small to be felt - and as said also quite negligible compared to the other forces acting on the airplane. If the earth would have been spinning very fast, then yes - the effect would have been more pronounced, but the earth is not spinning very fast. Yes, the rotation speed of the airplane is big compared to the speed of the airplane, but that doesn't count, it's outside the reference frame. The airspeed - the airplanes speed through the atmosphere - is constant.
Your weight is actually less at the equator than at the pole - the centifugal forces at the equator is 0.03 m/s^2 - not much compared to the gravity at 9.8 m/s^2. Due to the centrifugal forces the earth is also not completely spheric, but a bit squeezed out around equator. This makes a person on equator further away from the center of mass, which again causes the gravity to be less pronounced. This effect is slightly bigger than the centrifugal force. Source
I made a very similar analogy about how heavy drinking affects people recently. From day to day they feel fine compared to the last day, but they can’t accurately compare to a year or five ago.
I actually watched a proof video of that equator centrifugal math just yesterday 😆
The mathematic models & explanations work as models, but seem far removed from my experience. These are truly incredible speeds the earth is supposedly moving at & incredible rate change going north & south but no measurable physical afffect on any part of the earth nor is there any consistent measurable affect on travel despite these huge supposed physical forces.
We have highly developed & accurate senses to detect motion & balance to protect ourselves. We perceive much smaller rate changes in every other possible example. Yet the earth spins so fast it causes a bulge, but we can’t measure it on the ground or see water affected any differently near the equator.
