If you do, then I recommend you look into the centrifugal equation. Fc = mv^2/r
Well, the Round Earth radius is about 6,400 km everywhere, and circumference is about 40,000 km.
Vt= 40,000 km / 24 hr = 460 m/s
Ac = v^2/r = 460^2/(6.4e6) = 0.03 m/sec^2 (also available like this: https://www.google.com/search?q=centripetal+acceleration+at+equator)
Gravity is 9.81 m/
So I don't know how on earth anybody got the notion that a spinning earth would fling anybody off. Yes, our tangential speed is about 460 m/s. Yes, our centripetal acceleration is 0.03 m/s^2. Yes, gravity is over 300 times this amount. So you won't weigh much less in Ecuador than in Greenland.
I just want to mention that this math works only if the mass of the earth is indeed accurate.
There is no way to calculate the density of the earth.
We have only drilled about 12km deep, and the materials vary greatly throughout the earth. There is water, ice, clay, dirt, sand, rocks, trees, etc... there is no way to accurately calculate the density, therefore there is no way to accurately calculate the mass of the earth.
Why can't anyone proof how the G constant that newton came up with is actually accurate?
So your earlier comments on the centrifugal force were just a lie, right? I asked you for your numbers because I knew you were wrong. It is pretty clear you never worked out the math. Maybe I'm wrong - I'd still love to see you take a stab at this.
You can Google how the mass of the Earth was calculated and how G was derived. We know it is accurate because we can use these numbers to predict how objects will behave in orbit, etc.
OK......
Look at it this way.
The formula for the Fc is meant to demonstrate the very real force that is currently present based on the Globe model.
Now, in order for the mass of the earth to be accurate as you say, you must know FOR SURE what the density is.
In order to calculate for the force of "gravity" you need to know the mass of the earth ACCURATELY so that you can make it LAW.
Please tell me how is the earth's density accurately measured FOR SURE if the deepest we have ever drilled is like 12KM?
Are you telling me sonar, x-ray, etc.. can penetrate the radius of the earth to get us actual data values that we can use to calculate an equation that is the LAW?
Now, think of this: how does gravity know how hard to pull? No matter what size an object may be, if you get rid of air, they will hit the ground at the same time.
Look at this from a .edu physics Q and A:
Follow-Up #1: Why fixed gravitational acceleration?
Q:
So the force of gravity pulls harder on heavier objects, and it pulls every object no matter what the mass (neglecting air resistance) toward the Earth with enough force to have it accelerate 9.81 m/s/s. But what i don't understand is how this force changes. Like how does gravity "know" how hard it needs to pull the object to make it go 9.81 m/s/s faster. And also, why does Earth have gravity and other objects do not?

A:
Let me take your second question first. It's not true that other objects lack gravity. According to Newton's theory of universal gravitation (published in 1687) absolutely every object exerts a gravitational pull on every other object. The Earth's gravity is most noticeable around here because the Earth is big. Smaller objects have smaller effects. The first direct measurement of the gravitational force between two small objects in a lab was published by Cavendish in 1798.
Now we get to the trickier issue- why the gravitational acceleration depends only on the position of an object, not on its size or what it's made of. Although this was described by Galileo in about 1590, it wasn't explained until Einstein developed general relativity in 1916. Gravity is most accurately described not as a force but as a warping of the spacetime within which all things move. Each object at a particular place and time sees the same warped spacetime. If you try to describe the motion as if it were occurring in Newton's flat spacetime, as we like to do, you get the same acceleration for any slow-moving objects, because that acceleration really just is a measure of the same spacetime curvature.

https://van.physics.illinois.edu/qa/listing.php?id=164They use a THEORY to explain a very real thing that cannot be explained otherwise.
LOL you tell me you know G is accurate because of calculation done to put objects in orbit..... Have YOU put an object in orbit?
Gravity cannot be proven .
The force that holds us down is something much different than we have been told.
Just like theory of evolution, there is not palpable evidence.
