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 ...

Does earth revolution speed slowing down because of small drag from space is not empty?
I read that universe is not empty, in least dense parts has 1000 atoms per cubic meter, does that slow down earth speed?
Why these atoms are there, why they are not attracted by surrounding gravity ...

Has a heavier atmosphere and the relocation of oil around the Earth had a measurable effect on the rotation of the Earth?
I am wondering if the man-made carbon emissions put in the Earth's atmosphere over the past 100+ years, and also the relocation of oil around the Earth over this same time period, has had any ...

Are there torques affecting Earth?
Since the time it takes for the earth to complete one rotation about itself (i.e., the time we call "day") is not constant, then the angular speed is also not constant, that is, there is a ...

Energy needed to stop the Earth's inner core ---and its effects?
As you will most possibly know, a misreading of this paper by the media caused kind of a "panic" about how the Earth's inner core had stopped or even reversed its rotation and its "...

How exactly does the Moon stabilizes Earth axial tilt?
There are many references regarding the Moon stabilizing the tilt of the Earth's rotational axis. I'd like to see some support for that claim, more than non-sequitur handwaving "Moon causes tides,...

Will the Earth ever stop rotating?
Will the Earth ever stop rotating or will it rotate for the entire lifetime of the universe (assuming that the Sun didn't exist, so the Earth would survive to the Red Giant phase)?

Does the earth’s rotational angular velocity change?
This is what is written in The Feynman Lectures on Physics, Vol. 1 (ch.5)
We now believe that, for various reasons, some days are longer than others, some days are shorter, and on the average the ...

Why is climate change triggering faster rotation?
On July the 29th 2022, the Earth finished its rotation about 1.5 milliseconds earlier than the entire 24 hours. Scientists link this to climate change, saying that a possible reason could be due to ...

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 ...

What's responsible for the earth to rotate and for the objects on it to rotate with it? [duplicate]
Three questions arose to me:
The first is what is responsible for the earth spinning? Is this just newton's first law in action - having been formed out of the material in the cluster of clouds after ...

Earth's unimpeded rotation for billions of years [duplicate]
My nephew (7th grade) has stumped me with this question.
If I spin a top, it eventually stops, because of friction, air
resistance etc. How come the Earth has been spinning non-stop for 4.5
Billion ...

Why does the rotation axis of the Earth wobble over time?
I've learned recently that the rotation axis of Earth (axial tilt or obliquity) oscillates between 22.1 and 24.5 degrees.
I would like to understand why does that happen.
Having a basic understanding ...

Can we stop the Earth from spinning?
When we walk on the ground, we push the ground backward and hence the ground pushes us forward and we change our position. The effect of our force on the Earth is very minute (literally negligible) ...
