Question

how fast does the earth move and why we don't feel that moving?

Answer 1

Speed is relative. How fast is Earth moving relative to what?



The Sun? -- 66,000 mph (107,000 kph)

The center of our Milky Way galaxy? -- 486,000 mph (782,000 kph)

The Local Group? -- 673,000 mph (1,083,000 kph)

Earth is moving at a constant speed through the universe. You don't feel movement when you're moving at a constant speed. You only feel a change in speed, which is acceleration.



The same reason you don't feel movement on a airplane, because the airplane is travelling at a constant speed, not acceleration.

If you're really interesting in learning some more about what you have just asked, search on Youtube for "Special and General Relativity" - it will give you a true understand how speed works.

Answer 2

It revolves around the Sun at about 66,000 MPH and rotates at 1,000 MPH at the equator but it takes a whole year to go once around the Sun and all day to rotate once around on its axis, because of the large distances involved. If you were on a merry-go-round that only went once around all day you wouldn't feel that motion either. Basically you don't feel it because there are no bumps or vibration associated with the motion, and the rate at which it is turning is so slow that you can't get dizzy from it. You can go at any fast speed as long as the speed never changes and there is no vibration or bumps you would never feel it. As others said, it is like being in an airliner going 600 MPH at 30,000 feet in calm air. It doesn't even feel like you are moving.

Answer 3

At the equator, the planet is spinning at 40000 km per day, which is about 1700 kph. Away from the equator that speed is determined by the size of a circle drawn east to west with its centre at the axis, so for example here in the English Midlands we travel at roughly 1000 kph. The poles are effectively standing still in that sense.



We are also orbiting the sun at about 106500 kph and the sun orbits the centre of the Milky Way at around 66000 kph. The Milky Way itself is moving in the direction of Virgo at something like 4 million kph and space itself is expanding, which is a kind of motion.



The reason we don't feel any of this is that it doesn't change speed very much. Earth's rotation is slowing down very, very slightly. The pull of the Moon gradually slows the day down - about the time the dinosaurs died out, there were about 370 days in a year, and that was 65 million years ago. It also speeds up slightly because of earthquakes. During the year, it speeds up and slows down in its orbit - slowest in June and fastest in December. None of these changes are big enough to be noticeable. You only feel movement when you speed up or slow down, or change direction.

Answer 4

The Earth has several different motions. We don't feel them because we are a part of the Earth, we travel with it, share its inertia and momentum. When you are in a jet flying at 600 mph does it "feel" that way, you feel acceleration at takeoff and acceleration in the other direction on landing, but during the flight one does not "feel the speed", same with the Earth.

Answer 5

Hey guys but remember the Earth doesn't have a perfect constant speed I may tell you. Because by walking exactly the way the esarth rotates you are giving it a posititiive tiny acceleration and vice versa. So it has acceleration. But it's so tiny that we almostttttttt don't feel it or even not feel it at all.

Answer 6

The Earth spins around once a day on its axis. For most people, that's about 700 miles per hour. You don't feel it because you can't feed speed, you body feels acceleration.



Have you ever been in an airplane? When it's moving at 600 miles per hour, you don't feel that. You can only feel changes in speed. A steady speed can't be felt.

Answer 7

You only FEEL changes in acceleration,



Good examples above about riding in an airplane at 600 mph.



You do not feel anything if the speed is perfectly constant.

Answer 8

We do feel its motion. All it really does is make gravity seem slightly less at the equator than at the poles (where all gravity is true gravity), because equatorial residents are accelerating inward.

Answer 9

its going at 176000 miles per second we dont feel it because its like an airplane it u dont feel anything because its going at such a fast speed

Answer 10

We do not feel it because it is not accelerating.
