Hi Matthew,
I think I replied to your question, but maybe there was a technical issue.
Maybe you have the change to talk to an astronaut who can tell you his experience. Or you could try to become an astronaut yourself! Then you can find out reality for yourself.
But, honestly, according to my knowledge and experience, the earth is round!
If you believe the Earth is round than it would be a pear shaped, A earth spinning fast is like dough of a pizza spinning and eventually it would flatten out, than people could really see the curvature of the earth.
You come up with "If you believe the Earth is round than it would be a pear shaped". It looks like you picked up a bit of a requote from
Neil deGrasse Tyson that left out some important information - yes,
slightly pear shaped, but since the polar diameter is 7899 miles and the equatorial diameter is 7926 miles it would look almost perfectly round in any photo you are likely to see.
Then you go on and come out with "A earth spinning fast is like dough of a pizza spinning". Well maybe an "earth spinning fast" might, but the earth is really spinning quite slowly - one revolution in about 23.93 hours (one sidereal day), or 0.000696 rpm!
We can calculate the centripetal acceleration from the earth's rotation by using A
cent = (v^2)/R
E. Easiest in SI units, so: The surface velocity at the equator is about 1671 kph, or 464 m/s.
The earth's equatorial radius is around 6,366,000 m. Hence the centripetal acceleration is A
cent = (v^2)/R
E = 0.034 m/sec^2.
Compare this with g of at the North Pole of 9.83 m/sec^2. So the centripetal acceleration is almost neglible compared to the gravitational acceleration!
Really, I think you need a better script writer. If you are thinking these up fro yourself, learn a bit more about the globe before coming out with more half-baked ideas!
