Change in $g$ effective due to rotation
$g$ effective at any latitude changes due to rotation of earth. Does it also change due to rotation when the body is at height or at depth or does it change only at the surface?
Edit: I am referring ...

Weight at the equator
At the equator, it is said that the weight of the object will be lesser than that at the poles. This is because of the circular motion at the earth. The explanation given is that the Earth’s ...

Does Acceleration due to Gravity take into consideration the centrifugal acceleration due to Earth's spin?
Is the gravitational acceleration we consider only the attraction due to the Earth's gravity or is it that of gravity plus the attraction due to Earth spinning?
We know that earth produces an ...

What is happening with the horizontal component of the Earth's centrifugal acceleration?
We know that the equator has the highest centrifugal acceleration caused by the rotation of the earth (a = 0.034m / s2) but it is negligible because the vector of the acceleration of gravity is much ...

Is it correct to say that different acceleration of free fall at the poles and equator is due to centripetal acceleration? [duplicate]
In one of the answers to this question I read that it was becsuse for an object experiencing circular motion at the equator, part of the gravitational force would have to provide for the centripetal ...

How to theoretically calculate the value of gravitational acceleration of my town?
We normally consider the value of gravitational acceleration $g = 9.8 m/s^2$ while solving the problem. But that is the value of $g$ at poles (if I am not wrong).
My teacher have given as homework ...

Do we feel the full force of the earths gravity even though the earth is spinning? [duplicate]
As far as I know, since the earth is spinning, centrifugal force should be throwing you off the earth. However, gravity counteracts that by being a stronger force. So if you stood an object with the ...

How is space ship's acceleration perceived if the acceleration is perpendicular to the velocity?
Spacecraft in orbit around the Earth are constantly accelerated by the gravitational field of Earth. That's why the spacecraft ($m \ll M$) is in an (elliptical) orbit around the centre of gravity of ...
