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.
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
Yep, and unfortunately a lot of fascists on Reddit.
I do like how whenever a conservative Lemmy pops up, it has more trolls than users and the mods abandon it within a few weeks.
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.
