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 ...

If I levitate at the same place will I come back to the same place after Earth taking it's one complete revolution? [duplicate]
so i have this question if i mean if we can levitate and decide to levitate and not stay on ground but at a place to look the ground, and we that earth rotates right and we rotate along with it cause ...

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 ...

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 ...

What would happen if the Earth rotated at the rate required to achieve orbit at its radius? I.e ~7k m/s instead of ~460 m/s
To achieve a circular orbit, you need to have a velocity of $$v = \sqrt{Gm/r}$$ which is about 7 km/s at the Earth’s radius, but the Earth’s rotational speed is only about 460 m/s (by taking the ...

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 ...
