how different would our experience be if the world was stationary instead of spinning?

Answer 1

Well, it seems there is some confusion with what actually is responsible for gravity and Earth's magnetic field. As Chimbles correctly notes gravity is related to mass and Earth's magnetic field is related to our planet melted core and how it moves.

Bu let's get to the point. First of all we have to define the word "stationary". It seems that you probably refer to the fact that our planet spins around its axis every 24 hours so that day and night are caused. This means that this motion is relative to the Sun. Motion in space is always relative, well at least in classic mechanics. Our world is spinning relative to our Sun. If it stays static with one face of the planet always looking to the Sun then we all will be certainly in a big problem. One side of the planet will be too hot and the other way too cold. This is not a strange case by the way. Mercury's rotation is almost fixed relative to the Sun. Almost, it is not completely fixed, Mercury still has some spininng, but too slow. Our Moon, is also another example of fixed rotation, she always shows one face to us; our planet's gravity frozed her rotation so the Moon always greets us with the same side.

The consequences of living in a planet that does not rotate relative to its mother star are profound. Biology as we know it requires the right temperature to exist, this means a planet too hot is not a very nice place for life to exist. Oceans for sure will not be possible in world like that and liquid water perhaps possible only in limited quantities near the place where is always sunset or sunrise. Same thing will happen to our atmosphere, too cold in one side, possibly making gases to condense as liquid, and too hot in the other.

So, spinning is a good thing after all.

Answer 2

I'm astounded by how many people think that spinning causes gravity. It doesn't!

In fact, spinning has the opposite effect. If you put something on a disc, and then spin the disc, that thing gets thrown off. So the Earth spinning actually has a tendency to throw us off. It's only because gravity is so strong that we stay on the ground.

So if the Earth didn't spin, the pull downwards would be stronger, so we couldn't jump as high and buildings would have to be stronger and probably less high. Instead of there being a day/night cycle of 24 hours, it would last 365.25 days - since the Earth goes around the sun once a year. The moon would still have the same side facing Earth at all times but would appear to orbit at a different speed ... but I'm not sure whether that would be faster or slower, it depends if it's currently going in the same direction as the Earth's spin!

Answer 3

Yes, gravity is caused by the mass of an object, the larger the object, the stronger the gravity. It does not matter if it is spinning or not. Spinning, on the other hand, pushes objects away from the surface of a globe, but as long as the gravity is stronger than the push from the spin, the objects will stay sitting on the surface.

If the earth didn't spin at all, then one "day" would have the sun rising and traveling across the sky for 6 months and then it would be night for the other 6 months. Needless to say, life would probably not exist on the planet. It would be boiling on one side, and frozen on the other.

Answer 4

Spinning does NOT create gravity!!! Everything with mass has gravity wether it's moving or not.

If we wern't spinning (on our axis) then the following things would change:
[- One half of the earth would be in perpertual night and the other in perpetual day
- We would see the Moon rotate (ie not have the same face to us all the time)]
[Xexyz (below) is right on these ones. I must admit that I rushed my answer to dispel the 'spinning causes gravity' myth.]
- There's a good possibility that the Earth could not sustain life on all of its surface.

PS: The Earth spinning does not cause our magnetic feild either. That's caused by internal convection currents in the core and the interaction of the core with the outer core.

Answer 5

Rotation does not cause gravity. Rotation creates centrifugal force which is the opposite of gravity. If it were not for gravity, centrifugal force caused by the earth's rotation would hurl everyone and all their toys off into space.

Since the sun would rise and set in one year periods, vegitation would not get enough sunshine for half of the year, too much the rest of the year, and die. If that didn't kill them changing weather patterns with less rain would. The oxygen supply would decrease until everyone suffocated.

Nights would be much colder.

It would really mess up my golf game so it would be OK.

Answer 6

confident no person might have freedom under Matriarchy. The feminist governments might eliminate all threat from society and we'd have a huge mom State. adult men are extra companies to take adverse aspects and to blaze trails interior the pursuit of objectives. it incredibly is why organic decision has placed adult men in can charge a minimum of politically and economically. adult men are the utilising tension at the back of evolution. If feminists have been in power i think of we'd see a regression interior the human species because of the fact weak spot and emotionalism may be valued extra beneficial than tension.

Answer 7

It would be the same as if it was the moon - which DOES NOT spin.

One side would ALWAYS face the sun - one side ALWAYS in darkness. So one side would bake - the other freeze. The only habitable areas would be near the light/dark divide unless living in massive heated or cooled buildings. Underwater & underground habitation may be preferred to escape the light / UV.

Answer 8

We would never have existed. The wold's spinning causes gravity and also the Magnetic Field that surrounds our planet. Without gravity we would fly off, without the magnetic field we would have no atmosphere, and the world would be a barren lifeless rock bombarded by radiation from the sun.

Answer 9

We wouldnt exist. The world's spinning motion causes gravity and keeps us on the earth.

Answer 10

Wouldn't we all have fallen off the earth not that we would have existed in the first place
