I know this is a joke but if anyone is wondering it's because they build those things to go towards the air, otherwise they would be going away from the air and it would be hard to breath. Earth is going away from the air too but luckily it has trees attached to itself that make more air and leave it behind, that's where wind comes from.

This guy knows his stuff
Calvin's Dad over here.
i'm taking a meteorology class and can confirm that this is how wind works.
Im sure going against the force of gravity vs gravity pull to the earth has a lot to do with it too.
Wow am I on facebook?
Yes, now out with your deeply ingrained racist ideologies or I'm gonna sic gran on you.
Those men are just very good friends.
I'm appalled at the amount of people in this comments section who failed elementary grade school level of physics and also somehow failed to notice this is the shitpost community
It's not...
Maybe it was supposed to be, but it's just a regular meme sub
Acceleration vs. Velocity
Not quite. When you're rotating, you are constantly accelerating in a tangent direction to the diameter. So the poster is right that we should be feeling a force shooting us away from the center of earth.
Except the force of gravity cancels out the centripetal force and then some.
So [force of gravity] - [centripetal force of Earth's rotation] = 9.8m/s^2
The difference is about 0.5%. A mass weighing 100kg at the north pole would only weigh 99.5kg at the equator. Most of the difference is the centerfugal force of the earth's rotation.
I've not checked the numbers, but apparently it's detectable in Olympic sports. More height records get broken at equatorial latitudes that higher ones.
If you want to just pick the fastest velocity we can measure and we're currently moving at thanks to dark energy the Milky Way galaxy is moving away from other distant galaxies faster than the speed of light.
I think I feel it
I thought so too but it ended up just being an encumbrance of vapors
Man, it'd be so funny if the entire atmosphere just straight up locked in place. Heck, forget rotation, have it keep it's X/Y/Z in the universe static and just straight up disappear as our solar system moves on.
Xkcd kinda did a video on it except the earth is the one that stopped. It's pretty much exactly the same result though
That's cause earth isn't actually rotating at all. The entire universe rotates around earth.
Ik this is a joke but if anyone is wondering it's because units of linear motion (km/h, mph, etc.) do not accurately describe rotation. Rotational units like rpm are much better as linear units give a misleadingly large (though technically correct) number.
If anyone is wondering it's actually because of frame of reference. The first two images have speeds in relation to the rotation of earth, the last imagine uses a different frame of reference. If you put the last image in the same frame of reference as the first two images the number there would be 0km/h, because it would be moving in relation to itself.
It's actually because the thing that makes you make those faces is the acceleration, not the speed.
All three reference frames shown are accelerated, non inertial frames. But the first two have "fictitious" centrifugal accelerations somewhere around 0.5-2.5 g. The third frame has a detectable centrifugal acceleration, but it's like 0.003 g or something, and can be lumped in with gravity for many types of problems.
It's actually because of wind resistance, the air is moving the same speed as the ground when the earth turns so you don't feel it.
(don't @ me I'm just following what I recognized to be a humorous pattern of technically correct "well actually"s)
Maybe my math is wrong but: The Earth's radius is about 6,371 kilometers. With this large radius and a 24-hour rotation period, the centripetal acceleration at the equator is only about 0.034 m/s². This is tiny compared to Earth's gravitational acceleration of 9.8 m/s². So the centripetal effect is only about 0.3% of gravity's effect.
CHECKMATE ATHEISTS!!!
velocity V acceleration.
Uh, is this supposed to be a humorous jab at flat earthers, or do you actually think that this doesn't add up and out yourself as a flat eather and in this case do you wish an explanation?
Maybe I should've put this in lemmyshitpost because I didn't expect anyone to think it was serious.
I have very sensitive antennae when it comes to flat earth bullshit and also started to develop an allergy to non-science. So I beg your pardon that I asked...
Well you aren't the only one, so maybe I should have laid the sarcasm on more clearly. I thought most people would read the title as tongue-in-cheek.
Honestly the internet has made me paranoid about who is and isn’t serious and who may or may not be a stupid twat
Sorry captain, but I've heard a lot of Flat Earthers that use that exact phrase and act like its a gotcha that the Earth supposedly moves with 1675 km/h (it doesn't, it rotates at a 15 degrees per hour drift ^Thanks^ ^bob^) can't be felt.
Wow, I'm surprised they even try to explain it mathematically at all. Like, if you're going to believe something crazy, numbers clearly aren't going to make or break your conviction.
Oh yeah, they use loony toons maths to explain certain aspect of reality while a globe earth would explain it all at the same time.
Any intelligent joke requires a disclaimer because of flat earthers, Qanoners and conservatives.
