CHECKMATE ATHEISTS!!!
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
I was about to say gravity is stronger but it has already been said.
The earth isn’t rotating and shaped like a pyramid
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.
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.
Wow am I on facebook?
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.
They let scientists do drugs?
Well maybe we should just turn the roller coasters around and go the other direction.
velocity V acceleration.
Space doesn’t have air dummy
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.
40,075,000m circumference / 86,400s = 463m/s?
Yes, that is the speed you’re going, then the acceleration you experience due to the change in direction as the earths surface revolves about an axis is a = v²/r. R being the radius of the earth. This gets us our small acceleration value.
You do experience this small acceleration as a very small reduction in weight. You actually weigh more at the poles than the equator. You don’t feel the velocity at all, as the whole planet is moving with you.
That’s cause earth isn’t actually rotating at all. The entire universe rotates around earth.
If earth speed + hooman speed = no go
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!
Obviously 1685 Kmh is too much for your cheeks
