I've been looking all over the internet and I've asked chatgpt and everything, I've done the calculations and I'm still pretty baffled on why Polar orbits require a higher speed by almost 3x the speed of a normal orbit going at the equator, the things that I keep seeing is that orbits that go around the polar orbit do more coverage and require a higher speed to deal with this. Now I do understand higher speed is require to cover greater distance, but keep a satellite in orbit shouldn't have anything to do with coverage, your distance away from the planet is what allows to cover more/less.
Both polar orbits/equator orbits should be covering the same amount, and maybe a little more at the equator because of the earth rotation, now why I'm pretty confused about is that the earth's equator has a way higher distance around it then a polar orbit so technically it should have a way higher velocity to keep it in orbit. The only thing that I can seem to think that would be the answer to this is an angle on the satellites trajectory, but it would need to be corrected over and over and over to even maintain it in orbit, and it wouldn't even have anything to do with drag.
if anyone can possibly answer this, it would greatly be appreciated.
thank you
