You are spinning at 465 meters
per second right now.
Earth moves very fast. Everything within earth’s atmosphere is constantly
spinning. You can’t feel yourself spinning on earth for the same reason that you
can’t feel yourself moving while you are on a bus. That is because earth and bus
are both known as “frame of reference.” Frame of reference is a particular sets
of beliefs or ideas on which you base your judgment of things.
You can certainly see the earth’s rotation. Things on earth surface are all
moving with you, so there’s nothing to see, but you can definitely see the
motion relative to the stars and planets.
Earth spins at a speed of about 1000 miles per hour and obits around sun at a
speed of about 67000 miles per hour. We do not feel any of this motion because
sun and earth have constant speeds. You will only feel motion if your speed
changes. The spinning of earth reduces the amount of weigh when you travel to
the equator due to the centrifugal force of spin.
The sun and moon rises in the east and sets in the west because of the direction
we are rotating in. But the earth is spinning around on its own axis. If you
setup a video camera pointed at the night sky, you will be able to see stars
moving, too. From our frame of reference, it looks like those objects are
sliding past us. From the point of view of sun we are all spinning in circles.
Earth is moving at a fixed rate and we are all moving along with it. And that’s
why we don’t feel Earth’s spin.
