If the earth is spinning

Thanks Newtonian Nerd, I can explain this, Troll Feeder and Basic physics. I really liked your answers, they were nice to read too, clear. And funnily enough, I might get a book!

At approx 1670 km per hour according to the scientists, and moving at 107K km per hour as well why don't we all fly off? Why don't we feel it? If I ran in the opposite direction at that pace would it feel like I was on a treadmill?

If I stood on one of the poles would I get really dizzy?

If I jump, does the earth move beneath my feet?

If I'm in the sea, why do I move at the same speed as the water?

km/hour is a measure of linear velocity, and not rotation. The earth rotates once per day.

OK I'm confused about this bit though because I read an article which kind of inspired some of these questions and it explained how they calculated it and they said "spin" which I took to mean rotation. I will have to look up linear velocity.

This was the article anyway

Maybe I meant how not why. Ugh.

..cause the earth is flat and motionless. There is not 1, not even 1, legitimate and real picture of Earth or any satellite found. I know this is hard for most of you who have been brainwashed with text books, media, print and your teachers/peers and family to believe this but it is 100% true. I also expect more downvotes than upvotes. Google "satellites" then click "images". Find me one legitimate picture of a satellite or of Earth. You won't find one. Dinosaurs are also a complete lie. Yes, you will find the NASA computer generator images but not a real picture of Earth or of "satellites" cause there are none up in "space" or above Earth. First poster got 37 downvotes for good reason. Kool-aid drinking, media-controlled folks who have let others think for them don't like it when REAL questions like the original poster brought up are discussed. Real talk.

I think the response the OP is looking for is the earth is not spinning, there’s no such thing as gravity, and the world is flat. I just answered all the OPs questions - and it didn’t even take that long.

Gravity doesn't exist and is a lie too. Jump off a building? Why do you fall? The mass of your body is greater than the air you are falling through. Why can can a ship float? Buoyancy force acting on the ship is much greater than the weight of the ship itself. Why can a helium balloon overcome "gravity"? Not even worth my time writing this. Most of mankind will still believe whatever their television sets, school textbooks, peers/family/friends who, too, have been brainwashed into believing these masonic lies, have told them. First rule..turn off your television news and THINK for yourself instead of letting NASA and your favorite news network do the thinking for you...

While we are discussing interesting scientific facts. How about that fascinating water cycle of earth? Did you know that we are drinking the same water as a billion years ago?

that glass of tap water you are drinking could have been Moses Piss at one time! Cool huh?

But how do you know they are computer generated? Is there a stamp at the bottom of the image that says “computer generated”?

Fully understanding this takes graduate level coursework in Special Relativity but I will summarize:

Due to time dilation and length contraction the process of "flying off" is happening but is happening very very slowly, so slowly that your body can compensate for it. If you were paying attention you would notice that a step at the equator feels slightly less stable than a step at the north pole, this is because your body and its millions years old brain have evolved complex compensatory mechanisms to prevent this "flying off" from happening, even if its happening very slowly (thanks special relativity). This is one of the main reasons by bipedal robots are so hard to make.

Based on your comments I'm guessing that you haven't traveled outside a 3-4 state region and are strongly religious.

I didn’t know Kyrie Irving was a runner!

(Uh, no. It only takes Newtonian physics. It all comes from the equation for acceleration in a rotating coordinate system, which in turn comes from the simple equation for a time derivative in a rotating coordinate system.)

Why don't we all fly off? - Because atmosphere has mass and is affected (moved) by objects touching it (the earth). After 4 billion years the atmosphere is moving in sync with the Earth. This is why you don't get blown off.

You don't get spun off tangential to the Earth, because compared to the force of gravity centripetal force is just a tiny fraction. If memory serves, about 0.3% at the equator. The centripetal force would need to be greater than the force of gravity for this to happen.

If I stood on one of the poles would I get really dizzy? If you get really dizzy making one complete rotation of your body over the course of a day, then yes.

If I jump, does the earth move beneath my feet? Yes

If I'm in the sea, why do I move at the same speed as the water? That's fluid dynamics. Pressure and drag.

You don't feel is because you are part of it.

You aren't ON it you're a piece of it.

In other words you aren't on the surface. According to NASA there are about 60 miles of atmosphere above your head that is considered earth. In order for you to jump and have the earth spin under your feet you would have to jump out of the atmosphere, or 60 miles high.

I don't believe any of those things, personally.

Yes... and I also heard that the iron in our blood is from the stars, but not entirely sure if that is 100% accurate, especially as I take manufactured iron supplements.

This thread reminds me why my Physics classes tests were graded on a huge curve.

Very interesting :) thank you. The odd thing is this is the one I have the most doubt in for some reason yet it is interesting. Yes, the article mentioned some of the differences between the equator and the poles but not in that way. I actually wish I could study physics more - there is so much to learn that it is overwhelming.

The reason I'm trying to understand it is to interface it with another area - in which physics understanding is commonly thought of as somewhat lacking.
