Why do not we feel the world is spinning...?
« on: September 12, 2017, 07:28:54 AM »
     Today we live on the surface without feeling the earth rotates. It looks like the world is standing still, the sun, the moon, and the stars. Ancient people believe this. Until a few hundred years ago, this man began to understand the truth.
     Now we know The Earth rotates evenly around its axis and rotates around the Sun. But we do not feel it because we move along the earth as the earth rotates and the air around it moves. If so, why did not we fly away from the rotating world? Because of the weight that pulls everything else on the planet. Including ocean water into the world.
     By observing, we know that the Earth rotates. One is that the rotation of the world causes day and night if the world does not rotate. The side that approaches the sun is the day. And the turn away from the sun shall be night. But everywhere in the world, we find light and darkness every 24 hours, the distance that the world revolves around itself.
     It revolves around the sun by 365 ¼ days, which is called a year. The rotation of the sun causes seasonal changes. People in the strip near the pole Observers change the season easily as it is hot. Or cold, the plants also change their way of life. It is time to fall until the leaves are bare. Then it's time to break the new leaf. Flowering The lives of many local people have changed in these seasons. But the neighboring countryside of the equator did not find much difference from the seasons.
     The inclination of the earth's axis causes a change of season by tilting 23 ½ degrees from the vertical, causing each pole to approach the Sun, half a year, leaning out of the sun. So the northern hemisphere gets more sunlight than under six months. And six months less sunlight. Which will find the cold in Christmas and New Year while snow. Cold, cold, snowy in Europe and North America, but hot in Australia and South America.

The most basic reason, is the force generated from the spinning, is far less than the force generated by gravity. As such, we only feel the gravitational force. The Earth isn't actually accelerating either, which is what you can feel. If you're in a car doing a steady speed, or a plane doing the same, can you feel the fact you're moving? Same principle because the Earth is pulling all of the air and water (and therefore us too) along at that same, steady speed.

 But we can find out that earth rotates. Top of the tall buildings are farther from earth and as earth rotates the top of the building has greater speed than ground below it. Or bottom of very deep hole also rotates little slower than the upper part. Using this you can determine that earth rotates. Start for example with information about Giovanni Battista Guglielmini

Anyone can detect "spinning", but not at 1 rev per day. You might be able to understand this paper better than I.
Canal–Otolith Interactions and Detection Thresholds of Linear and Angular Components During Curved-Path Self-Motion, by Paul R. MacNeilage, Amanda H. Turner, and Dora E. Angelaki.
Hopefully you might find a simpler reference.
From what I can gather any rotation slower than about 1 revolution in 10 minutes would be imperceptible.

So there is no way for a person to detect any rotation of the earth.

Yes, you flat earthers fiddle around pretending that you know the truth, while these terrible globularists develop equipment that can directly measure the rotation!
There are plenty of available gyroscopes relying on the Sagnac Effect that can easily measure the earth's rotation once in roughly 23 hours 56 minutes.
This sort of thing: Honeywell Aerospace, GG1320AN Digital Ring Laser Gyroscope

This one has a "drift" that would do very well: Angular Random Walk (ARW) 0.0035 deg/hour (typical).
 Angular Random Walk means that in the absence of any movement,  after an hour it will typically show 0.0035°.
Since the earth rotates at about 15°/hr, this gyroscope will easily measure the earth's rotation.

Plenty more where they came from. Any modern airliner with an Inertial Navigation System will have something similar.

Still you will not believe anything that does not fit your belief. I don't know whether it's denialism or whether you're all Luddites.

Are you implying ''we'' can detect the difference in spin between the ground and on top of a tower measuring a  couple of 100's meters the most  (how much of 1% is that compared to the ground   ...)?
And we can hardly measure the curvature over 5 km, because of naughty refraction and all sorts of defusion techniques ?

It is this kind of logic that tells me something is very wrong with your globe  ::)

Because it's not accelerating or decelerating.

If you are cruising on a plane and the conditions are calm, you can't feel yourself travelling at over 500mph. Need a change of speed to feel it.

Really? Not this one, right at the South Pole!

The operation of the Foucault pendulum is much easier to understand when done right over the North or South Pole. At those locations, the earth is simply revolving underneath it.

Here is also this report on a very "off-the-cuff" Foucault pendulum at the South Pole.
Quote
South Pole Foucault Pendulum
Winter, 2001

Abstract:
A Foucault Pendulum at the South Pole was determined to have a period of 24 hours, ± 50 minutes. The acceleration due to gravity, g, was determined to be 9.85 ms-2 ± .03 ms-2. The rotation of the Earth was in a clockwise direction if looking down from above the South Pole.
From: South Pole Foucault Pendulum

Bit long to include much of it, but it's worth reading.

Wikipedia claims that the "sea-level effective gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh about 0.5% more at the poles than at the Equator."
Maybe that 9.85 m/s2 ± .03 m/s2 wasn't too bad for such a rough setup.
But how does your ::) infinite flat earth ::) explain this variation from the poles to the equator?

It's a bit telling that these terrible globularists can actually perform measurement's, do calculations and get consistent answers.
You flatularists can't even come up with a consistent answer for something as easy as the height of your sun above the earth.
With a parallax so large that a protractor could be used, you still can't work it out - what a useless mob!

Of course, there's a simple consistent answer to all this:
it has been suggested that the earth is a rotating Globe with a very distant huge sun, ever thought of that?

And I thought jroa was a FE ? 
The earth is steadily rotating at the same speed-not changing velocity or accelerating as per the FE idea ?
Also consider the speed from an RPM stand point.
The earth rotates at 1 RPD  (One Revolution Per Day.)
1/60 minutes x 24 hours RPM = 0.000694 RPM
 The same as the speed of the hour hand on a 24 hour clock.

No.  They're not "powered" by magnets LOL.  Do you even know the physics behind their principals of operation—simply put, they repeatedly convert kinetic energy into potential energy.  And of course the earliest pendulums—and still many today—don't utilise any magnets, but have to be periodically "restarted" by hand.

Why would we feel the earth spinning?  If you’re in a car you don’t feel the movement unless you’re accelerating/decelerating.  If you’re in an airliner doing 500 knots you don’t feel the movement unless, again, it’s accelerating/decelerating. 

Now add to the fact our daily lives are within the planetary boundary layer.  In this case “planetary” just denotes scale and is nothing more than the standard boundary layer we calculate in basic fluid dynamics.

We don’t feel the earth spinning because it’s rotating at a constant speed (no acceleration); because we live in the fluid boundary layer so the air at the surface is moving at the same rate in the same direction as the rotation of the earth.  It’s also why the higher you go from the surface the higher the wind speed...again, basic fluid dynamics, easily calculated so no mystery. 

Also, gravity forces the atmosphere towards the center of the earth creating an additional force that increases the depth of the boundary layer that we don’t normally have to account for in fluid dynamics.  The Cavendish experiment and LIGO have more than proven the existence of gravity.

You tried to correct kennykirklan by saying that a change in velocity was necessary instead of change of speed.  I'm just pointing out that, by definition, a change of speed is a change of velocity.

I agree, an "aeroplane . . contently changing directions on a round Earth" is experiencing an acceleration. Let's work out how large.
For simplicity, suppose it is travelling around the equator, where the earth is travelling at about 1,675 km/hr or 465 m/s.

Take the first case where the aircraft is flying from east to west at 800 km/hr or 222 m/s.
          The nett velocity of the aircraft is (465 - 222) m/s, or 243 m/s and the centripetal acceleration is 0.0093 m/s2 or 0.09% of g.

Then take the case where the aircraft is flying from west to east at 800 km/hr or 222 m/s.
          The nett velocity of the aircraft is (465 + 222) m/s, or 688 m/s and the centripetal acceleration is 0.074 m/s2 or 0.8% of g.

So you might feel a touch lighter flying west to east, but these accelerations are small and near enough to constant, so there will be no sensation.

And this change in effective g is quite measurable:

If you'd actually read the article you link to, you will see that the Foucault pendulum will function fine for a couple of hours without needing the boost of the magnetic collar. More than enough time to demonstrate its function.

Since an aeroplane is constantly changing directions on a round Earth, and so are you and I, I don't see the point in your post.

Technically-speaking, you're correct jroa, but not for the reasons you think.  Commercial aircraft normally follow a "great circle" or orthodrome course due to... wait for it... the sphericity of the planet.  And the fact that they do change course slightly but constantly proves that the earth is NOT flat.  Oh dear.   ;D

An aircraft taking off from (say) 50 03 59N, 005 42 53W and flying to 58 38 38N, 003 04 12W would have an initial bearing of 009° 07' 11", and a final landing bearing of 011° 16' 31" for example.  You can check this out using the haversine formula—which relates to the sides and angles of spherical triangles—if you don't believe this.
