If that happened,
Will it affect to the gravity?

beamthegreat said:Every building and object would be instantly be crushed near the equator and gradually reduce in damage as it was nearer to the north or south pole. Objects in the equator are moving at around 1674 kilometers per hour so if the Earth immediately stopped it would be like crashing a jet plane into the ground.
As for the centrifugal force, it wouldn't really be noticeable. From the link below, people on the equator weighs about 0.3% less due to the centrifugal force exterted on them. You can read more about it on the link I provided below about the Earth rotation and the effect on gravity.
Some unknown physics are needed to make the Earth stop rotating. You apparently are assuming that this unknown physics pertains to rocks only. Why? Certainly you could also assume that the same magic that works on rocks also works on water, buildings, people, etc.beamthegreat said:My point is that if the Earth were to stop instantly it would certainly be devastating to everything on earth.
This is one of those "what do the laws of physics say would happen if the laws of physics are wrong" kinds of questions.
Bandarigoda said:Then also tsunamis will be happen?
Will it affect to moon?
What about the air?
A fastest air should be start, then might affects to air planes, and other objects on the land. Am I correct?
Why?Drakkith said:Yes, the ocean would still be moving and would flood most of Earth's landmass.
Once again, why do you say this?Lots of wind. LOTS of wind.
Drakkith said:Nothing would happen immediately, but the long term effects would be that the Moon stops receding from Earth. This happens because, without rotation, the Earth cannot transfer its angular momentum to the moon through the tides.
Nugatory said:The moon is still orbiting the Earth so we'd still have tides. They'd just rise and fall twice a month instead of twice a day.

Once again, why do you say this?
It would require magic to suddenly make the Earth stop rotating. Why are you assuming the magic only works on rocks? It's magic. It can do anything it wants.
Nugatory said:The moon is still orbiting the Earth so we'd still have tides. They'd just rise and fall twice a month instead of twice a day.
Drakkith said:Of course, I never meant to imply we wouldn't, only that the Moon would stop receding from the Earth.
It would work the other way around, though. Angular momentum transfer would be from the Moon's orbit to the Earth's rotation if the Earth wasn't rotating or if its rotation rate was longer than a lunar orbit. The Moon would slowly spiral in rather than out.Nugatory said:And because we still have tides, the angular momentum transfer processes will still be at work, just operating at more slowly. The moon's recession continues.

Ignoring questions of HOW the rotation would be stopped and all the devastation due to "conservation of momentum", the force of gravity would not change at all- that depends only on the mass and radius of the earth. A person at the equator would feel a little heavier because how heavy you "feel" is the force of gravity minus the centrifugal force necessary to keep you on the surface of the Earth as it spins.Bandarigoda said:If that happened,

The idea of Earth's rotation stopping is a common topic in science fiction, but what would happen if it actually occurred?
Yes, if Earth's rotation stopped, the length of a day and night would become equal to the length of one year, meaning each day and night would last 365 Earth days.
If Earth's rotation stopped, the atmosphere would still be in motion due to the Earth's own rotation around the sun. However, the winds would become much stronger, causing extreme weather patterns.
The lack of rotation would cause temperature differences between the light and dark sides of the Earth to become extreme. This would result in extreme weather patterns and temperature changes, making it difficult for life to survive.
Earth's rotation creates a centrifugal force that counteracts the pull of gravity. Without this force, gravity would become stronger, resulting in a decrease in weight for objects on the surface of the Earth. This would also cause the Earth to become slightly more oblong in shape.
It is highly unlikely that life could survive on Earth if its rotation stopped. The extreme weather changes, lack of day and night cycle, and changes in gravity would make it difficult for any living organism to survive. However, some deep-sea organisms or bacteria may be able to adapt to these extreme conditions.
