Question about the orbits

in Quran 21:33 and Quran 36:40 are the sun and moons orbits meant from our perspective? (with the rising and setting of them) bc the orbits of the day and night seem to mean from our perspectives so wouldnt the same apply for the sun and moon? i know the sun has its own orbit, but in these verses the way the day and night and sun and moons orbits are mentioned seems relative to each other and it wouldnt make sense that the suns orbit affects the day and night The word being used, falak, فلك, is it referring strictly to a circular motion of the sun and moons orbits? Or can it refer to the way we see the sun and moon rising and setting in a curved way?
