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.
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.
