We canât feel Earthâs rotation or spin because weâre all moving with it, at the same constant speed. Earth spins on its axis once in every 24-hour day. At Earthâs equator, the speed of Earthâs spin is about 1,000 miles per hour (1,600 kph). The day-night has carried you around in a grand circle under the stars every day of your life, and yet you donât feel Earth spinning. Why not?
At any given moment, we are all moving at a speed of up to 1,674 kilometers an hour, thanks to the Earthâs rotation, By definition, the Earthâs rotation is the amount of time that it takes to turn around once on its axis. This is, apparently, accomplished once a day â i.e. every 24 hours.. However, there are actually two different kinds of rotation that need to be considered here. For one, thereâs the amount of time it take for the Earth to turn once on its axis so that it returns to the same orientation compared to the Universe.
