Direction of deflection of Coriolis force on Earth
I'm a bit confused about Coriolis force direction on Earth. The observed deflection is to the right in the northern emisphere and to the left in the southern one.
But what about an observer in the ...

Coriolis object deflection and conservation of angular momenutum
I'm trying to understan kinematic inertial explanation of the apparent deviation of objects due to fictitious forces in rotating Earth.
Take an object moving from the equator northwards, or ...

What force is needed to turn the Earth Pole-over Pole. Eg. UK now on Equator? [closed]
Specifically, if someone could specify the Joules energy required to force the Earth to slowly rotate the poles end-to-end by say 1 degrees rotation, and by 5 degrees.
To be clear I mean to literally ...

Why does earth spin counter-clockwise?
If we observe the earth from the north pole, we can see that the earth is rotating counter clock wise direction. The earth spins due to angular momentum, but why only in counter clock wise.
Why ...

How does Foucault's pendulum work in a place other than the poles?
I find it easy to understand how Foucault's pendulum works at the poles, the pendulum oscillates in a fixed plane and we, along with the earth, rotate around it. So it appears that the pendulum's ...

Will the sea form a concave surface?
Without neglecting the fact that the earth is rotating, let us be in a ship (such that there is no relative motion between sea and ship) in a sea that surrounds the northern most or southern most ...

Can we calculate the frame dragging force of the Earth?
Although clearly this force would be significantly greater with a rotating black hole, is it still possible to calculate this drag for say a satellite orbiting the Earth?

Does the Earth's rotation affect an object in the stratosphere?
Does the Earth's rotation affect an object in the stratosphere?
Example: I attach an object to a weather balloon and let it go at latitude +40.7, longitude -73.9 (New York). It goes up until it hits ...

Does the Earth rotate vertically too?
We know that the earth has seen several Ice Ages.
And we know the Earth's magnetic poles seem to flip once in a while.
Could all of this be explained by a once every 250 Million Years or so the ...

Will we gain some extra hours if we travel in the direction of the rotation of the earth? [closed]
I heard that If we travel for long distances in the direction of the rotation of the earth, we can gain some extra hours in the journey.
Is it true? What if we travel in the opposite direction?

Proof that the Earth rotates?
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 ...

Does the Earth rotate the same encased in ice during the height of an Ice Age as it does when the bulk of it's water is liquid and always in motion?
Ice Age vs. Now.
Does the Earth rotate at the same rate when encased in ice during the height of an Ice Age as it does when the bulk of it's water is liquid and always in motion?

Would it matter if the Earth rotated clockwise?
In the Futurama episode "That Darn Katz!" they save the world by rotating the Earth backwards saying it shouldn't matter (which direction Earth rotates). If Earth rotated clockwise and remained in it'...

Why doesn't the Earth release you as soon as you escape it?
I've always wondered, that since the Earth is moving at a very fast velocity around the Sun, why is it that when astronauts leave the Earth, the Earth doesn't immediately move away from them at ...

Video of Earth spinning?
If the Earth is spinning or rotating at a really fast speed, why haven't we seen any videos from space of it spinning when we get a lot of photos of it?
