These examples are stupid. In the first two you are spinning around, but the air around you is NOT. Thus the forces you feel are due to your interaction with your surroundings. In the final example with the earth, EVERYTHING is concurrently moving at that same speed.
you assume the earth and everything is moving. Can you prove the earth is moving through natural science , testable observable measurable repeatable experiment?
The sun proves it every day. Its been tested, measured and observed on a daily basis for billions of years.
The sun proves the earth is moving? What has been measured? what has been tested? Even Einstien said “I have come to believe that the motion of the Earth cannot be detected by any optical experiment.” I guess you out did Einstein ;)
I observe Earth's rotation with an "Optical experiment" every day when I rely on data from polar orbiting earth observation satellites (Sentinel 2A and 2B). Although they go in a polar orbit (as opposed to alongside the equator) what's beneath them changes with each orbit at the exact same rate as Earth's rotation speed.
I would be happy to receive any evidence that the data from these satellites are fake so that I can stop wasting my time (you can find it all here if you're interested). But so far, we're able to use the data to spot forest fires and illegal deforestation, monitor and protect water reserves, and help provide images after natural disasters. So at least it's doing good work for humanity despite being "fake" :)
Have a nice day.
I suppose you missed the part where I mentioned can YOU measure or test ? Using practical repeatable natural science . Surely we can rely on supposed orbiting satellites ( which I dont see how that proves the EARTH is moving , its the satellite that orbits) So no YOU dont observe earth rotation, you interpreted data that you have no first hand access to or verification of, and are using the strawman argument of spotting forest fires etc as an observation of the earth moving?? I think not, forest fires and water reserves and images of natural disasters can easily be taken from high altitude instruments (drones, high altitude craft, balloons etc) and in no way proves the earth is moving. If that observation of the earth moving is factual im sure there would be other experiments that can be done to confirm such motion. Thats where your straw man appeal to authority arguments fall apart. Its not about data being fake or real, but interpretation of data based on faulty assumptions.
No, I did not miss that. I've built and launched a satellite as a student myself which we equipped with our own communications device and observed how we received the signal at different ground stations across the world as the satellite passed over them. So that is me doing an experiment.
Yes, it does observe that the Earth rotates around its axes. The satellite moves in a straight line from the North pole to the south pole and back above the North pole, making no turns or manoeuvers. Yet the ground underneath changes with each orbit and it changes at exactly the same rate as the Earth's rotation speed. That is both proof of rotation and it is also a direct observation of data that we do have "first-hand access to" and we can (and have) validated repeatedly.
I did not invoke that as proof of rotation. Only referenced it to share with you what I am using the data for in my job, and also noting the fact that at the very least it works and has real-life benefits.
If you can obtain the same amount of data, updated at the same frequencies and with the same quality as we receive via the source I gave you above, then I will quit my job immediately and join you to make a startup. Because that would be amazing abd we would get rich.
No, you can't get that large amounts of data "easily" with drones, balloons or aircraft. We receive new images of every single corner of the Earth every week with our satellites. Planet also provides new images every single day. You would need an amazing amount of drones, balloons or planes to do that repeatedly over every corner of the world. It's also easily disproved as most countries have good control over their own aerospace and while I have 24/7 access to new images above any corner of the world every single day, there are not drones/planes etc overneath every single corner all the time.
I have just given you one, and @justtryme90 gave you another (i.e the reappearance of the sun). How many would you need? Or what would it take to prove it to you?
When did I appeal to authority? I'm just sharing how I use satellite data myself, and I try to explain how I see it as evidence of a round earth and of rotation. I am not claiming authority and I am curious to hear your opinion too.
Fine then use one of these:

It's a non optical experiment.
how do you think that works? how is the atmosphere 'pulled along' ?
a merry-go-round is more apt example. everything would be flung off. we all know that from childhood. well most do.
my 'why i think the earth is flat post'
Gravity
No, that's a stupid example. A merry-go-round doesn't have significant gravity.
It's round. Not that it matters, the whole debate is the stupidest thing ever. What does anyone gain by convincing people the earth is round when it isnt? Absolutely fucking nothing. It doesn't matter what shape the fucking planet is. However, it's round.

nasa gets 54 million bucks a day. how is that for a reason to lie?
how about this... they keep you thinking you are small, insignificant in a accidental universal.
Nothing. Because it is round.
The earth was known to be round long before the days of NASA. So that's an irrelevant justification.
How does this change if the world is flat? Regardless you are still small, insignificant in a accidental universe. Just on a flat planet.
The earth is round, we know its round. Satellites show that its round. Satellites work because its round. Other planets are round, the sun is ... round. The shape is just natural for the organization of spinning masses that large.
Maybe you should ask your self why the earth is spinning in the first place? Or even better will it always continue to spin? The answer might surprise you. It won't. It will eventually stop spinning. In fact we can even measure that. The length of a day actually gets longer over time :) (that time frame is big, but its measurable by current technology)
Take a dinner plate, and spin it around at a steady pace so it spins exactly once in 24 hours. That is how fast you are moving. You wouldn't even be able to see the earth move in the picture above. Making it look blurry as if it is moving fast is very dishonest.
Go take a commercial jet flight. You will travel at 550 mph, and yet, and yet...by some miracle, you can hold up a drink and drink it!
Flathead ideas are so dumb.
And yet, and yet! If you fly with the spin of the Earth, you still reach your destination! Also, we are not sealed tight, there is no barrier between the atmosphere and the vacuum of space. Rip the roof of that plane off and see what happens to you and your drink.
It's for this exact reason that spin is not measured in MPH/KPH but in RPM. The earth is spinning at a PAINFULLY slow 0. 000696 rpm . Do this example, put an ant on the hour hand of a clock. He's already rotating at twice the speed of the earth. Does he feel it? No.
Now, take the ant and put him on a merry go round spinning at the rate of 2 revolutions per 24 hours. The ant is now rotating about 100 times faster on an MPH basis than he was on the clock because of the increased radius of the disk. Does he feel any different? Is he being blown off due to the increase in forces? Is he struggling to crawl along? No.
Now find a disk that is even larger, the size of an adventure park ride and do the same thing. Now he's spinning 4 or 5 times faster than on the merry go round on an RPM basis. Does he feel different? No. You can do this out to infinity of size and the ant will not feel any different... because he's still going painfully slow.
That's why spin is measured in RPM's and not MPH/KPH. The two examples you gave are rotating at TENS OF THOUSANDS of times more RPM's than the earth. If you honestly believe the earth is flat, why do you need to dramatize to make your point? Facts and logic would be enough.

I redid the math for you, using 6 feet and 20 feet as the estimated diameters of the rides.
Yes , you fly with the spin of the earth, and with the spin of the atmosphere, and you reach your destination. That surprises you? Interesting. Does it also surprise you when you reach a destination when you drive a car that is moving with the spin of the earth?
Yes, there is no "barrier" between the vacuum of space and the atmosphere, there is also no friction. So there is literally nothing to slow the atmosphere down from matching the speed of the earth's rotation. And of course the plane is travelling 550 mph faster than the atmosphere, so a large amount of wind will result from the roof being torn off. The point was that you can be travelling at a good rate of speed, yet still being able to enjoy a drink. And when you are standing in your in your living room enjoying a drink, you are travelling at exactly the same speed as the atmosphere, just like the air inside the cabin of the airplane. So no 1000 mph wind, because the atmosphere is traveling at the same 1000 mph that you are, just like the air in the plane cabin is travelling along at the same 550 mph as the plane is.

Yes @uvas maybe you are angry for something, but there are zero reason to insult people. peace
You are right, I edited my original post.
you are in a contained unit. you are travelling in a straight line.
what happens when you turn a corner? you get pulled to that corner. we are in a state of perpetual turning on a globe earth model. you would feel it all the time. just like a merry-go-round... does it every stop feeling like motion on there because you came to a stable speed? no...
Go sit on a merry-go-round and have someone spin it so it spins one time in 24 hours and tell me if you can feel it.
When you are standing on the surface of the earth, that amount of force is not pulling you to the left or right, it is making you weigh slightly less. It is pulling you away from the surface of the earth, slightly counteracting the force of gravity. Your difference in weight from the equator(with maximum centrifugal force) to the north pole (with minimum centrifugal force) is about 2 pounds for the average man. And if you ALWAYS feel 2 pounds lighter when you are standing on the equator, how would you notice?
get me a merry-go-round the size of the earth.
yes, i'm sure i'd be able to feel it.
You are sitting on a merry-go-round the size of the earth, how lucky is that? Can you feel it?
haha. you are funny.
Let's keep this civil or flags will commence :)

awww, did I hurt the big baby's feewling? lolz
So either he is an idiot, or he is a dishonest fuck, take your pick...the vast majority of these flatheads are dishonest people trying to make money by posting untrue and misleading stuff. Sue me if i don't care for charlatans
@einarkussk ... thank you for smoking out the shills
Loads of information. Thanks. Love it. @einarkuusk Followed
You cant feel it , you are too small ! cried the globeling
