I feel like I’ve thought about this my entire life and can never wrap my head around it.
****On a merry go round the further you get from center the more centrifugal force you feel and consequently the more centripetal force (they are equal and opposite if you are at equilibrium). But at the center they are both net zero.
****On earth, presumably the equator would exert the maximum centripetal force due to it being the furthest away from the axis. The centripetal force keeping you on the ground is gravity and that equals your centrifugal force trying to fling you off earth.
****But at the poles, how….. and why….. where tf did gravity go? There’s no centrifugal force which means there’s no equal and opposite centripetal force (gravity).
Gravity, electricity, and magnetism are all one in the same force; Acceleration towards a null pressure point in the aether. On a merry-go-round, pressure (acceleration) is created, from it’s center, and outside of it is the null point of which you accelerate towards. Now, everything is magnetic to some degree; that is to say that no matter what matter is composed of, it all accelerates towards the lowest pressure poin In it’s proximity. On a planet, the very center of it is a sustained low-pressure point, exerting great magnetic attraction to everything around it. So being surface-dwelling life forms, we feel the pull from outside-in. Now, the earth spinning which causes it to be the oblate spheroid, where the majority of mass is at the equator, is just an example of rotation causing mass to migrate away from the pull of the lowest pressure point: the center of the earth. At the poles, there is objectively less mass and less (outward) rotational pull, but the force pulling inward keeps you planted on the ground.
Now more on the merry go round, You'd be correct to think that at the very center, you wouldn’t feel a pull at all. But why is the force opposite? Why does a merry go round try to spot you out? This is a matter of scale. There is indeed a null pressure point at the very center, but the rotational speed of the ride is more than enough to try to fling you outwards, easily overcoming the the null point within its center. However, a rotating amusement ride does not possess the power that lives in the center of the earth. What is in the center of the earth is a sustained, low pressure point, of enormous effect, that we feel all the time.
I’m still studying this topic and have not found the correct words to use to describe what exactly this point is and how it is sustained. The answers that academia gives out are not correct, because this is a matter of aether-physics, which they are scared to approach because it will require 300 years of physics to be rethought. That’s why it is slow going trying to find these answers.
Thanks for the reply and great info.
One thing I was not accounting for is that centrifugal force actually increases with decreasing radius from axis. Meaning the closer to the poles, the more centrifugal force.
