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
1675 + 10km/h
1675 + 100km/h
1675km/h
Turns out that 1675km/h is the magic number, anything above that is dangerous
I'm a leading scientist on speed, and this is the answer.
They let scientists do drugs?
Who do you think invents the drugs?
Can confirm. Heisenberg invented meth, saw a documentary about it.
I remember learning that before the invention of the locomotive, people thought that 30mph was some kind of barrier that the human body could not survive.
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.
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.
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.
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)
CHECKMATE ATHEISTS!!!
