Can I argue that the Earth's surface is an inertial reference to explain why we can't feel it's rotation? [duplicate]
Passengers on a plane cannot feel the plane move when it's at cruise speed. Can the same reasoning be extended to earth's rotation to explain why we cannot feel it rotate even though it's rotating at ...

Why is the Earth not an inertial frame of reference?
From many sources I have found the explanation that the Earth is not an inertial frame of reference because it rotates around its axis.
However, nobody mentions the rotation about the Sun.
What I ...

Would the Foucault pendulum experiment work on a rotating flat Earth?
If the Earth were to be flat, but still rotating with a constant angular frequency, would the Foucault pendulum still show it's precessing motion?
The angular velocity of the precession can be ...

Static model of the Earth motion
Believe it or not, an old man I know in 2015 still negates the Earth orbital motion around the Sun.
He believes the earth is rotating on itself and acknowledges this gives day and night on every ...

What is the proof, without leaving the Earth, and involving only basic physics, that the earth rotates around its axis?
By basic physics I mean the physics that the early physicists must've used to ...

Earth-Centered Inertial (ECI) reference frame as approximate inertial frame of reference
In many practical applications, one can consider the Earth-Centered Inertial (ECI) reference frame approximately as an inertial reference system, though strictly speaking, it is non-inertial.
Is ...
