A matter of rotation

We all know the earth is spinning, but how fast? And we dont get throwen off because of gravity, so shouldnt we all be being stretched with gravity pulling down and syntrifical force throwing us off? Would gravity be a lot stronger if there was no rotation?

Answer #1

1037.5833333333… miles per hour. at the rquator, less as you go North or South. earth’s equatorial circumference is 24,902 miles. therefore it takes 24 hours to make one complete revolution The minor effect of centripetal force, is unfelt, but absent the rotational velocity we would all die, A) from burning on the sunward side, or freezing on the night side, and B) even at the terminator (the line dividing day from night, with tolerable temperatures, the lack of rotation means lack of moving air masses, ocean currents, resultant tidal forces would produce extremes.

Answer #2

Earth’s rotation speed most probably is 1674.66km/hr.

To your second part, when Earth does not rotate, gravity would still remain the same, but the whole world would be in a standstill as the earth doesn’t rotate around its own axis. That would be unimaginable. The syntrifical force is very minute for us to feel its effect, so it doesn’t really post any significant damage to us, so we won’t get thrown off so easily, with gravity acting downwards.
