Earths Spin

0  2016-06-07 by narcoleptik_ninja

I posted this in askscience but the moderator said I needed a flair yet a lot of posts don't have them... Anyway, they say we don't feel the earths spin because it is constant. However it is fastest at the equator and gets slower as you move away from it. So my question is how come no one ever notices the change in velocities when traveling towards or away from the equator? I honestly can't find an answer for this anywhere and was hoping the scientific minds of r/conspiracy could help me :)

Why not post an ELI5?

I have no clue what that is I'm not a Reddit whiz lol

try posting here: /r/explainlikeimfive

Someone responded on askscience saying it's because the spin is too weak. That's not what we were taught but ok!

Sorry, glad flyyyyyy was able to help you. I'd stepped away. I'm a bit of a newb around here as well and assume most people know more than me.

Because we don't really notice the velocity anyway, the gravity pulling us down is far stronger than the force of the rotation of the earth.

There is a difference between the rotational force we receive at the equator when compared to the poles, but the change is seriously minute (I can look up the numbers if you'd like) when compared to the other forces we feel anyway.

Valid question. Its because there is no spin. The round earth model that everyone has been indoctrinated with has a lot of flaws, yet we are not allowed to question it. Good on you for thinking on your own feet, unlike the majority of the crowd!

And yet the many flaws in the flat earth model are ignored when pointed out as flat earther's merely repost the same tired, debunked talking points.

There is no one flat earth model..... Yet the globe earthers like to make one up so they can laugh at anyone questioning the shape of the earth. Go figure.

Isn't it telling that there is no one flat earth model? If the universe was as simple as you folks claim, generating a consistent model that explains all of the observed behavior (including the sun, movement of stars over the decades, orbits of the planets, different stars in northern/southern hemisphere, etc) should be relatively easy. Yet even flat earthers cannot come to an agreement on how the model should explain that behavior, or even if it can.

Well, where is the funding for flat earth research? None. I repeat none. So your point is moot.

So, because you have no funding that automatically excuses why your model(s) are unable to explain basic observed phenomenon?

That's wholly incorrect. Seems like you don't look at the sky enough. Keep believing in your brainwashing. You must really love being a slave.

Then tell us why all of the flat earth models are full of crap that can be easily disproved? I do look at the sky, and I see movement of the stars and moon and sun that the flat earth continually cannot explain consistently. You and others have yet to offer up viable explanations for all of what we see.

The only brainwashing I see here is from you, in your paranoia that everyone in the world is trying to keep some "massive truth" from you.

Let me ask you one question for your well trained eye then - 9/11 inside job, yes or no?

Trying to change the subject because you can't support your claims?

Not at all. Scared to answer the question? To show all of us your real colors? :D

Then support your claim rather then changing the subject.

Pity you if you think it's a change of subject. Lies are lies. One is just like the other. Now you can continue to sip your koolaid and leave me the hell alone :)

It's an interesting question. Lets say I was on the equator and flew to Michigan. The speed at the equator, according to Google, is 1037mph. At the 44th degree latitude, the earth's speed would be cos(44) * 1037 = 0.719 * 1037 = 745mph. So there would be a 292mph difference in horizonal velocity of the earth beneath when you go to land. Yet I don't think airplanes ever account for this change. How could that be if the world is what we're taught it is in school?

Say that flight you specify takes 9 hours - that means you have a rotational velocity change of 32 mph per hour. That's a minimal change to account for when you're flying at 700mph to begin with. It's not like they have to account for that velocity change all at once - it occurs gradually over the course of the flight.

Of course, but do they? I'm not saying it's impossible for them to adjust. I'm saying that as far as I've been able to dig up, they don't.

If you drive from Miami to NY, do you notice having to adjust for the rotation of the earth? It's the same thing, just over slightly shorter periods of time.

That's assuming there's rotation. Is it your position that the Coriolis effect doesn't influence ballistic trajectories then? It either does or it doesn't right?

It absolutely does. Snipers have to factor that in when they are firing at ranges of a thousand yards or more. There's a good discussion of this at the link below.

Then why isn't it affecting that plane? Why do they have to make changes in regards to a bullet but a plane will just naturally compensate and move with the earth? Shouldn't the same principle apply?

No one is saying that it isn't affecting the plane. On the plane you are actively making changes the entire flight anyway - the changes you need for rotation are automatically built in to what you have to do to stay at the desired flight speed and pointed in the right direction to your destination. It's not like there's a whole separate set of calculations/flight changes you make to compensate with the rotation speed change over the course of a long flight.

Not at all. Scared to answer the question? To show all of us your real colors? :D
