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? please explain me.
mubashirmansoor said:For example the water level in a well is much lower in a moonless sky, but a lot higher when moon is present...
mubashirmansoor said: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.
acolavin said: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.
acolavin said:but strictly speaking, water would not gain volume out of the cup and leave vacuum at the bottom of the cup.
acolavin said: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.mubashirmansoor said: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?
The Earth moves at an average speed of 67,000 miles per hour as it orbits around the sun. This speed is known as the orbital velocity and is calculated based on the distance between the Earth and the sun.
The Earth's movement is primarily caused by two factors: its orbit around the sun and its rotation on its axis. The gravitational pull of the sun is what keeps the Earth in its orbit, while the Earth's rotation gives us day and night.
The Earth takes approximately 24 hours to complete one rotation on its axis. This is what gives us our 24-hour day and night cycle.
Yes, the Earth's movement does affect our seasons. The tilt of the Earth's axis and its orbit around the sun are what cause our seasons. As the Earth moves around the sun, different parts of the Earth receive different amounts of sunlight, resulting in the changing seasons.
No, the Earth's movement is not completely constant. It is affected by various factors such as gravitational pull from other planets, the moon, and even large objects on Earth. However, these changes are very small and do not significantly impact the Earth's overall movement and stability.
