You need it to understand that when you are standing in flat level ground for miles
But level ground isn't flat.
If this were not the case, an island as level as a sponge for several miles would be impossible to build structures on.
Why? Because you say so?
Just what magic is making is unstable?
its very existence proof there is no curvature as not only roads and bridges but buildings should have creased at the seams.
Why?
Again, you are just asserting pure garbage with no justification at all.
Yet NYC is very much level
It very much isn't.
It varies in elevation by over 200 ft.
And that isn't as a plane.
So if your delusional BS was true, why isn't NYC unstable, with visible creases?
And surely gravity and not adding microchips filled with code is the important part.
The question is how those components work?
They are microelectromechanical systems (or MEMS), functioning in a manner similar to a loadcell.
Without gravity, they wouldn't be able to tell which way is down.
Not than an accelerometer actually uses gravity either. Angular momentum is not gravity.
An accelerometer is not measuring angular momentum.
It measures acceleration, including the apparent 1 g you get from standing on the surface of Earth.
They lied.
Companies lie.
And why couldn't you source by lying, or just mistaken?
Did they actually examine each component and determine what it has?
For a Switch use for Breath of the Wild and Skyward Sword, yes you have an accelerometer. For a device that does minor tilting only, unnecessary and counterproductive.
What you should be asking is what is it trying to measure.
Is it trying to measure the orientation of the device, or is it trying to measure how the device turns?
Can you recalibrate it, so it thinks level is sideways, and then operate it relative to that?
