The fact that the Earth is rotating about its polar axis affects the escape velocity from the surface of the planet. Taking into account the earth's rotation, how does Vesc at North Pole compare to Vesc Equator?
How about North Pole vs. South Pole?
Greater at North Pole compared to at the Equator.
Same at North Pole and South Pole.
This is because F=mw2r and and rpole< requator; so max centripetal force needed at equator. Gravity is the at both points, but at equator, requires the extra centripetal force to keep the particle on the surface, meaning that it wants to leave more, so lower vesc.
