.....

Everyone keeps saying stuff, but not actually calculating anything.

The fact is that over such a large distance, the high velocity of a point on the equator wouldn't affect anyone much. I weigh 90kg. At the equator, the centripetal force exerted on me due to the spinning earth is only 3N. The force acting on me due to gravity is 883N. The resultant force is 880N, so not much difference (0.34%). C'mon, this is basic stuff.

It can easily be shown that F_g = 288.24F_c where F_g is the force acting on a mass due to gravity and F_c is the force acting on said mass due to centripetal motion. (In other words, as above, F_c is only 0.34% of F_g). This is at the equator.

Ok so, 1oz of gold(approx 1600) is worth 1600 X .34% = 5.76 less on the equator.

This again?  Gold's mass is measured by the Troy Ounce, an Imperial Unit of Mass. Not weight, mass. They use balance scales to measure the mass, not springs.

Ok so, 1oz of gold(approx 1600) is worth 1600 X .34% = 5.76 less on the equator.

Also your calculator sucks.

Correct use of SI units, subscripts, consistent notation, and even parenthesised explanation. You could publish that shit.

Went to a good Uni! Tuks of Niks!!

I'm debating whether to actually reply to you because your 'how clever I think I am':'how clever what I am saying is' ratio is really skewed.
Relativity is nothing to do with what your are talking about.

But basically, you literally said nothing correct in that post. The reason we don't feel any movement on the earth isn't because of its speed at all. It's because everything around us moves at the same speed as the earth.  It could spin once a second and we wouldn't notice because everything else, including ourselves, is spinning once a second.

Incorrect. The centrifugal forces caused by basic physics, which you clearly skipped class to, would fling you off.

It does have to do with relativity. When you are on a spinning sphere, at time "a" you are travelling through space tangent to the sphere at that location due to momentum. If this change in direction from travelling tangent to point "a" to travelling tangent to point "b" is too sudden, you will certainly notice it.


When I said the "massive planet rotating at 5,000,000 mph", I meant everything was spinning with it, as you say, the same speed. So, the guy on the "planet" is rotating at 5,000,000 mph, along with everything on it.

What did I say that was logically or factually incorrect? I am always open for learning, so if you or anyone can explain what I missed, I will correct myself.

If the earth is rotating at 1038 mph and we don't feel it because the atmosphere is rotating in unison with it because it's somehow gripped to the ground, then why don't miners "underground" not feel the earths rotation?
After all, surely the atmosphere isn't gripping the underground with them is it.

If the world is hurtling upward at 9.8 m/s² , why don't airplanes have to constantly aim upward?

They do, but we've been brainwashed by NASA so we don't notice.

Tuks of Niks indeed! I'm glad that I at least learned a bit more than the correct way to write stuff down, although for some professors it is far more important to explain every single little thing you write down with parenthesis (and to get your font and margins right) than to actually use your knowledge to solve a problem given to you accurately and produce a system that works. lol.

Everything you've said is correct, except you're using that word again - relativity. It's obvious now that you're just misusing the word, and don't actually think that the speeds we are moving at are relativistic speeds.

I should also note that the massive planet rotating, say, 10x as fast as Earth, with the speeds at the equator being 5M mph, you need to also consider the gravity of such a large beast. We'd be surely crushed, and even more-so at the poles.

Relativity does not only refer to Einstein's special and general theories.  In fact his theories were only to extend relativity from Galilean Relativity.

While I've read about Galileo's work in this field, I didn't realize it was named relativity. Thanks.

A miner sat inside a small rail car underground should move in his rail car by the movement of the ground above him, in the real world of course but in the magical world of the science way, something stops that happening. What?

Can you refrase the question?

So you're saying that a miner sitting in a rail car, under ground should what?...

Isn't the fact that he's not pushed up or through the mine wall proof he is moving with the earth?

There is no atmosphere supposedly rotating with him, he's free from the friction of that, so why doesn't he move inside the rail car?

Beside the fact that yes, there is air underground, air has nothing to do with it. Even if there were no air you still won't notice the rotation. If you sat it a swivel chair that turned around once a day, you wouldn't feel it either.

What a miner might notice is Coriolis force. If he sped along a track travelling straight north, he might not feel it but he might be able to measure it. On a flat, non rotating Earth there would be no such force.

I'm very surprised Johann Benzenberg's 1804 experiment (or Ferdinand Reich's later in 1830's, or some of the others) has not been mention in this thread so far! It does, afterall, use a mine shaft to demonstrate earth's rotation =)

Of course they have to aim upward to get into the sky. However, I didn't say to get into the sky. They level out once they reach desired altitude, the aren't constantly climbing to get away from the Earth.

They still need to be pushed upward. That's why they don't turn the engines off when they get to the right height.

So, a guy in a rail car should move underground because of the ground above him. What? Everything is moving. At that location, he is moving, the ground above him is moving, the ground below him is moving at the same speed.

Everything you've said is correct, except you're using that word again - relativity. It's obvious now that you're just misusing the word, and don't actually think that the speeds we are moving at are relativistic speeds.

Yes, we would be crushed. I know that. Analogy fails at that point. Pretend gravity is as strong on that surface as on the surface of the Earth. 

As someone else stated, relativity does not have to do with time slowing down and such. It simply means, if everything is moving at 1030 mph in one direction, then no net movement is detected. They all might as well be standing still. What I was saying with the rotation speeds, a sharp curve in rotation tries to change our natural direction of movement. Like a merry go round. You are constantly being flung out side because of the super fast rotation, but you are holding on to go in circles. If you let go, you will fly tangent to the point at which you let go.

The Earth is simply not spinning fast enough in proportion to itself to fling us off. It takes 6 house to even go a quarter way around the circle of rotation. That is figuratively like standing on a merry-go-round that spins one full rotation every 24 hours. Now, we are on a giant merry go round (Earth), but it still is rotating once every 24 hours. At one point are momentum wants us to go 1030 mph in a direction tangent to the Earths surface. In one hour, our direction will change by 15 degrees. Every minute, our direction changes by 0.25 degrees. This is hardly enough of a change to notice.

However, on something that spins once a second, as that oblivious FE guy posted, your direction changes by 180 degrees in half a second. That is extremely noticeable.

Please note: Everything I posted is in relation to someone standing on the equator.

I posted this in the debate section, someone designed an experiment to verify the results of Faucults Pendulum with a game controller and spare parts, well within the budget of anyone with serious interest.

They don't point the nose up. The point the nose forward. Does Bernoulli's Principle not apply on a flat Earth?

How does he breath if there's no atmosphere down there with him?

But the wings create lift, which counteracts the downward force of gravity, or in the flat Earth case, would force the plane upwards at the same rate as the Earth is going upwards. It's equivalent.

When I was 1,600 feet underground I did not feel the earth rotating. I fact, nothing seem out of the ordinary. The earth is round.
