Main Question or Discussion Point
The earth is moving at a great speed about its own axis. Something inside a moving sphere also moves. Why don't we move with the earth? plz explain me.
That means you want to say that in a well, the moon will rise the level of the water as it does to the ocean water.For example the water level in a well is much lower in a moonless sky, but a lot higher when moon is present...
Actually, I think this is not a true statement. The force of gravity from the moon felt by the center of mass of the cup, with the average force felt by every molecule in the cup, would negate each other. You could argue that water tension could allow for water to be closer to the moon, but strictly speaking, water would not gain volume out of the cup and leave vacuum at the bottom of the cup.Yes but your glass has to be almost very full to overflow, due to the total amount of water which is quite a little compared to the well... Its difficult to observe this effect with a glass full of water but yet not impossible.
Solids & liquids are not the same... I think you mean the force acting on the cup & water inside the cup will cause the same effect on both objects. if so, as far as I know you are a little wrong... The force between solid molecules is much much much stronger compared to the liquids, hence liquid will overflow but no specific effect on the solid.Actually, I think this is not a true statement. The force of gravity from the moon felt by the center of mass of the cup, with the average force felt by every molecule in the cup, would negate each other.
There wont be any sort of vacuum at the bottom of the glass, as the bottom of the well is not vacuum...but strictly speaking, water would not gain volume out of the cup and leave vacuum at the bottom of the cup.
About non-rigid attachment, so is the water in the cup...The tides are actually caused because the water is a non-rigid attachment to the rotating Earth. Imagine a cup of water with a rotating cylinder down its length in the center inside. If the cylinder has rotational W, then eventually through friction between the water and cylinder, the water will gain rotational speed to W too. Now this is what is happening with the Earth-water system. If you add the moon to the system, you have to consider gravity.
The water level in a well rises and falls with the tides because underwater aquifers are essentially flowing bodies of water.If your statements are true I think there will be one unsolved question; Why does the water level in the well rise even higher during an eclipse?
