Why is Coriolis effect responsible for COUNTER-clockwise rotation in the northern hemisphere?
Based on the form of the force, $F_\text{cor} = - 2m\mathbf{w}\times\mathbf{\dot r},$ I would expect a projected particle to rotate clockwise in the northern hemisphere. This is confirmed by the ...

Why do we say that the torque on Earth due to Sun is zero?
Let's assume, the mass of Earth = $M$, the radius of Earth = $r$, the moment of inertia due to revolution of Earth = $I$, angular momentum due to the revolution = $L$, distance between the center of ...

Earth's rotation in an empty universe
I have read these questions:
Is rotational motion relative to space?
Rotation in an 'empty' universe
None of these talk about whether we can and how we can determine rotation of Earth ...

Flat Earth experiment, but with gyroscope
A man conducted "an experiment" (quotes really, really necessary) to prove that earth is flat. Here's a link. He used a spirit level, set it up before takeoff and expected the level to be tilted after ...

Measuring Earth rotation rate about its axis with gyroscopes
With gyroscopes having two basic properties, precession and rigidity in space, shouldn't we see an apparent movement (due to rigidity in space) of a gyroscope's rotor (gimbals) in relation to the ...

How do I experience Earth's movement?
We are told that Earth is spinning on its axis at 1037 mph— something that we don't usually feel because of the environment that moves with us as well. Is there any experiment with which we can know ...
