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.

If earth speed + hooman speed = no go
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 fact that your units are units of acceleration proves the guys point, no?
It sounded like the guy meant the 1700km/h is a velocity, not an acceleration, which is why we don't feel the force of acceleration.
I was pointing out that spinning is acceleration, just in this case we can't feel it due to other forces.
What are those pre-math numbers though? How screwed would we be if rotation doubled or stopped (regardless of the virtual impossibility)?
Have you seen the elementary school experiment where you spin an egg on a flat surface, then you stop the egg and let it go and the then the egg starts spinning again?
If the earth suddenly stopped spinning, the atmosphere would still be spinning at 1700km/h.
A cat 5 hurricane has wind speeds of 253km/h. So we'd be boned.

velocity V acceleration.
That's cause earth isn't actually rotating at all. The entire universe rotates around earth.
Wait, so if I drive fast enough I get a nice picnic meal?!?!
You see, that is another perfect example for why earth has to be flat, anything else just isn't logical!

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.
Obviously 1685 Kmh is too much for your cheeks
Love it!
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?
Poe's Law strikes again!
Maybe I should've put this in lemmyshitpost because I didn't expect anyone to think it was serious.
I thought everywhere was lemmyshitpost.
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.

1675 + 10km/h
1675 + 100km/h
1675km/h
Turns out that 1675km/h is the magic number, anything above that is dangerous
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.
I'm a leading scientist on speed, and this is the answer.
Well maybe we should just turn the roller coasters around and go the other direction.

Unfortunately it does add up :(
