I really have a hard time believing that the Earth is moving at a speed of 67,000 miles per hour through space

Replying when addressed and caring about someone who quickly resorted to the shill gambit are not the same thing.

Here, you want the math? Here's the math. Gravity is only slightly countered by the centripetal force of earth's rotation. At the equator where the velocity is greatest, 1,700 km per hour, the corresponding centripetal acceleration is equal to v^2/r where v = 1,700 km per hour and r = 6,378,000 m. Converting that to meters per second you get v = 472.222 m/s, so the acceleration would be 0.03 m/s^2. Earth's gravity provides an acceleration of 9.8 m/s^2, the amount it is offset by earth's rotation is essentially negligible.

Then please explain this to all who claim that the atmosphere stuck to the earth's surface is why we don't experience the sensation of speed.

Astro, do you not get tired of fighting with these brain dead turds day after day.

Their stupidity tires me out just reading it.

You're confusing vertical acceleration with angular momentum. Gravity pulls toward center mass, whereas cent. force is a perpendicular motion. And it still remains that gravitational force is ONLY concerned with mass and distance. Show me where the formula for gravitational force includes the motion of the two objects.

If the earth stopped spinning, gravity would be unaffected.

You're trying to explain basic physics to types that you would not even talk to in real life, because you would just be able to see the moron in their brain dead eyes.

I'm explaining it to you since you tried to make that argument just now. I don't know anyone else who makes that claim. If you do, great, now you can explain it to them.

Can we humans ruin our atmosphere and still continue living as before?
If the atmosphere doesnt matter?

Our air will stay put because of gravity?

What's stupid is continuing to read "brain dead turds" that make you tired. So is brown-nosing.

No, I'm not.

Centripetal force is in the opposite direction of gravity. But it's insignificant compared to gravity.

I can't believe I even have to explain this. I just showed you that the centripetal force is insignificant COMPARED to gravity. Do you not understand what it means to COMPARE two values calculated separately?

I could go back through the thread, or other similar threads, and list them, but surely you've seen it many times. They claim that the atmosphere moving with the earth's surface is why we aren't sensing the speed. That's not my claim, and I didn't make it up. I made no such argument; I've argued against it.

So, back to the OP: Since the atmosphere is irrelevant, then how would you convince the OP that the earth is indeed moving at a speed of 67,000 mph?

No, I haven't.

Well that is one reason. That's not the same as claiming that the atmosphere is what PREVENTS us from sensing the motion. If the atmosphere were not moving with earth but earth was instead plowing through it at high velocity, yes, you would certainly sense earth's motion.

Considering that OP is a troll posting mathematical fallacies (seriously, he posted that "2+2=5" - how can you not realize that he's being insincere?), there is no convincing him. It would be a waste of time to talk about astronomy, and how distances and velocities to the sun, other planets and other stars can be measured.

67,000 miles per hour

miles per hour is a comcept made up by man.

the earth doesnt give a fuck about your low level awareness

imagine a bee flying around

that bee is you.

you land on a human that is walking 5 mph.

as a bee, you wont even notice that you are moving because its slow compared to your normal speed

time is relative

Personally I'm done trying to explain facts to trolls. It's a waste of time and it's not even like they actually believe the things they post. They're just here to try to wind people up. Had a particularly nasty troll last week who went too far trying to accuse me of rape. I'm done with those fucktards.

I'm much more interested in discussing science with people who at least appear to be sincere and interested in an honest discussion. Sure, some of them might be trolls as well, but if they're not even going to invest the effort to at least look like a sincere poster then they're not worth debating.

My apologies for writing "centripetal" instead of "centrifugal".

Centrifugal force is perpendicular to the centripetal force. It goes in a circular path around a center point. In that experiment where you put a weight on a string and whirl it around over your head, then let go of the string, the weight does not fly in a circle and does not fly towards your hand; it flies away at a tangent to the circle.

But you are in error about centripetal force; it IS the direction of gravity:



You said centripetal force is opposite, whereas it's the same.

Define space.

lol go back to you hole in your ball head gaykeeper naza troll nobody is buying your bs

Typical brain dead reply.

Why?

Because like a moron you assume that I (and others) would read every single post of your little mind trying to get a grasp on reality.

No, I normally read the first post and then the last.

In this case I can only shake my head. SIX PAGES OF STUPIDITY.

Let me explain it to you like I explained it to my 5 year old daughter.

Firstly image you can see the atoms of all matter. Thus you do not see land, or air, but you see a massive ball of atoms. The denser atoms are in the center and the less denser atoms are on the surface of the ball.

In this case the less denser atoms is the air.

Take into consideration that the whole ball of atoms are spinning uniformly in the VACUUM OF SPACE.

Now if cannot understand this, you are either a troll or seriously retarded, in which case I would advise you to kill yourself in order to extinguish your blood line.

You're deeply, deeply confused. It's not the same. If it were the same then you're saying that objects that are quickly rotating will hold onto objects on their surface more tightly. Why don't you get this? You just went from claiming that objects on the moon and earth should be flung off by rotation to making an even more senseless claim that they should be held onto by rotation.

And this is supposed to be the writing of an intelligent non-troll, whose opinion should count. Wow.

Google Dunning/Kruger.

They are too stupid to realize that they are stupid.

I gave a link to the article I quoted; if it's in error, perhaps you could correct it. They said that gravity provides the centripetal force , meaning gravity = centripetal force, so it can't be opposite. They are the ones who are confused; I only quoted them.

I never said anything on the surface of a spinning ball should be held on by rotation; nothing even close to that.

LOL Fuck off cunt.

I do not debate stupid.

I mean listen to this brain dead fuckwit. Centripedal force is caused by SPIN moron.

Sorry Astro, I'm out of here, as I do not debate stupid. All you can really do with stupid is to mock and insult.

I'm in awe of your ignorance. Go to the link and see for yourself; centripetal force pulls toward center mass. If it didn't, the circular force would stop and the forward momentum of the object would take it off the circle at a tangent. When you whirl a weight around above your head by a string, your arm and the string are supplying centripetal (center-directed) force, which keeps the object from flying off. Centrifugal force is trying to pull the object away in a straight line. This is elementary physics.

One more...

You probably do not realize that I was mocking your use of the word centripedal.

No need to believe, you can try and prove or disprove it for yourself.

By claiming gravity is in the same direction you ARE claiming that anything on the surface of a spinning ball should be held on by rotation sir. If on the other hand you agree with me that rotation works to counter gravity than you must accept my calculations showing it's insignificant compared to gravity, sir.

Simple experiment as I've mentioned twice: put a weight on the end of a string. Start whirling the object in circles over your head. Let go of the string. The object will fly off in a straight line.

Centrifugal force is the angular momentum or circular motion; centripetal force is the string and arm holding the object from flying off. Gravity is the centripetal force; the spin of the earth is the centrifugal force.

Astro we have signs of brain activity.

Now Einstein, you just need to work out which force is bigger and you have your answer.
