网页The strength of the centrifugal force depends on where you are. It is greatest at the equator and zero at the Earth’s poles. We can calculate how fast the Earth would need to spin to balance the force of gravity (this is known as the ‘escape velocity’). It works out at about 28,437km/h (17,670mph).

How to explain the Earth's Equatorial bulge without

网页2021年1月12日The so-called centrifugal force is indeed a fictitious non-existing force in the inertial frame. But the centrifugal effect is very real. That effect is causing the bulging. The counter-intuitive thing is just that it is not a centrifugal force which is causing the centrifugal effect. Rather, the cause is inertia.
