A simple question
Just wondering how my basic physics-thinking is:
1. The earth is spinning and therefore there is angular momentum 'throwing' us away from the earth. (or is this negligible? ...in which case the rest of my thoughts below are void)
2. The earth's gravity due to it's mass is pulling us towards the centre (of mass) of the earth.
3. The force from earth's gravity is greater than the angular momentum (obviously... since we're still on the surface).
4. If the earth stopped spinning (and all the other disasters that would happen... didn't happen...) would the gravity caused by earth's mass "feel" a lot greater because there is no more angular momentum 'throwing' us off the planet?

Re: 11.3:1
Thanks for your time.
So we'ed feel about a tenth heavier.
At least I can still think in Newtonian terms :
Thanks for all the calculations too.
