Water always finds its level

To continue my theme of simple experiments you can do from your bedroom.

Think about the last time you put your hand in water.
You pulled it out.
Was it wet only on the top?

How good is that?
Dude you just destroyed them dumb FEer's!

No, but that's is because of electrostatic forces, and not gravitation.

Have you guys seen the ISS footage of wringing out a wet towel in zero g? It's really cool, also nearly impossible to fake with cgi.

No, but that's is because of electrostatic forces, and not gravitation.

perhaps if water carried a charge....which it does not.
But lets try a wooden ball or a stone which cannot carry a charge.

Are they wet?

Actually, water (along with just about everything else) seeks its lowest potential energy state.

I'm not saying the earth is not flat. I'm saying the argument "water finds its level" is provable false without leaving your house.

Waters seeks its own level perpendicular to the pull of gravity. Since gravity pulls to the center of the earth it pulls in a sphere, therefore there's nothing to object to.

Water does carry charges. It is made of charges. And the charges aren't always completely evenly distributed over the atom. Read up on Van der Waals forces and dipoles. Long story short, at very short distances molecules feels a weak electrostatic attraction between each other, and water molecules are like small magnets (they have two poles).

Waters seeks its own level perpendicular to the pull of gravity. Since gravity pulls to the center of the earth it pulls in a sphere, therefore there's nothing to object to.

Is the gravity stronger at the equator to compensate for the 1600 kph spin and weaker at the north and south poles for the 0 kph spin of the ball?
If so, gravity is very clever.

How would spin affect gravity?

Dunno, guess it woodn't!

Tappet, if you have something traveling at a constant velocity of 1600 kph, what acceleration is it subjected to?

Actually, the spin only reduces gravity by .03 m/s².

due to being slightly further from the core, gravity is actually slightly weaker at the equator than at the poles but as already mentioned the effect of the spin is very small.

The question really should be why you cannot work this out for yourself! All the information is available on-line.

I guess the thing you might search for might be "Centrifugal force".

Centrifugal force
In Newtonian mechanics, the term centrifugal force is used to refer to an inertial force (also called a 'fictitious' force) directed away from the axis of rotation that appears to act on all objects when viewed in a rotating reference frame.

plus a whole lot more
from Google centrifugal force
Or you might choose one of the many other sources.

Wherever you get the info

Now the earth has an equatorial radius of 6,384 km (Wikipedia again) or 6.384 x 10⁶ m and
the earth actually rotates once in a little under 24 hours^[1], or once in 86164 secs.
So on the equator the surface velocity is the (circumference of the earth)/(time for one revolution) or

[1] This is because in 24 hours the same spot faces the sun again, but in that time the earth has moved 1/365.24 of its orbit around the sun. So the earth rotates 360° in a bit under 24 hours.

Rotational speed at equator 1600 kph.
Rotational speed at north pole 0 kph.

Did you try that with other objects? Say, a candle? Wax paper? Teflon or paraffin block?
 
 
Did you try to pour some water in your palm? Was it covering your wrist, elbow and shoulder, too?

And gravity has the same force everywhere.
Sounds like magic.
Hey, we do not even need math for this one, just a little common sense.

Gravity doesn't have the same "force" everywhere. Pay attention more.

Yeh your right. Between 0 and 1600 kph it creates a whole bees dick difference.

It does not matter what anyone says, you will try to ridicule it!

You can't even do simple sums, you can't see that 465 m/s is almost the same as 1600 km/h and yet
It does really look like "I can't understand the globe, so the earth must be flat!"

But then how come these Flat Earthers can't decide what the earth looks like?

Can't work out how the sunset can do this?
Can't work out what even causes things to go down (or up)?

• Is it Universal Acceleration - looks ridiculous to me!
• Is it "denspressure"? - worse!
• Things just naturally want to go down - no reason, it just is!

Can't explain what cases lunar eclipses?

Do you wonder that it all looks ridiculous to Globe supporters who know what the Earth looks like - not that we understand all of it, but
