mkuu swali lako ni nzuri sana lakini wabongo utawajua tu hawependi kutumia akili.,kazi starehe tu>>>>

The probability for such an event is practically zero in the next few billion years. If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.

If the process happened gradually over billions of years, the situation would be very different, and it is this possibility which is the most likely as the constant torquing of the Sun and Moon upon the Earth finally reaches it's conclusion. If the rotation period slowed to 1 rotation every 365 days a condition called 'sun synchronous', every spot in the Earth would have permanent daytime or nighttime all year long. This is similar to the situation on the Moon where for 2 weeks the front-side is illuminated by the Sun, and for 2 weeks the back side is illuminated. This situation for the Earth is not the condition of 'stopped' rotation, but it is as close as the laws of physics will let the Earth get.



If it stopped spinning completely...not even once every 365 days, you would get 1/2 year daylight and 1/2 year nightime. During daytime for 6 months, the surface temperature would depend on your latitude, being far hotter that it is now at the equator than at the poles where the light rays are more slanted and heating efficiency is lower. This long-term temperature gradient would alter the atmospheric wind circulation pattern so that the air would move from the equator to the poles rather than in wind systems parallel to the equator like they are now. The yearly change in the Sun's position in the sky would now be just its seasonal motion up and down the sky towards the south due to the orbit of the Earth and its axial tilt. As you moved along constant lines of Earth latitude, you would see the elevation of the Sun increase or decrease in the sky just as we now see the elevation of the Sun change from a single point on the Earth due to the Earth's daily rotation.

For example, if you were at a latitude of +24 degrees North in the Summer and at a longitude where the Sun was exactly overhead, it would slide gradually to the horizon as Fall approached, but since the Sun has moved 90 degrees in its orbit, it would now be due west. Then as we approach Winter, you would now be located on the dark side of the Earth, and would have to travel in longitude to a location 180 degrees around the Earth to see the Sun 1/2 way up the sky because in the Winter, the Sun is 48 degrees south of its summer location in the sky. It's a little confusing, but if you use a globe of the Earth and orient it the right way, you can see how all this works out.

As for other effects, presumably the magnetic field of the Earth is generated by a dynamo effect that involves its rotation. If the Earth stopped rotating, it's magnetic field would no longer be regenerated and it would decay away to some low, residual value due to the very small component which is 'fossilized' in its iron-rich rocks. There would be no more 'northern lights' and the Van Allen radiation belts would probably vanish, as would our protection from cosmic rays and other high-energy particles. This is a significant biohazard.

Not everything -- but lots of stuff would.

There are two things to keep in mind:
1. An object in motion tends to stay in motion unless acted upon by an outside force.
2. Everything that is on the surface of the Earth is also spinning with the Earth, which is why we experience day and night.

At the moment of sudden stop, every object that was not firmly anchored to the Earth would continue traveling in the direction it was moving -- tangential to the Earth's surface. The degree of "lurch" would depend greatly on your line of latitude -- which reflects your distance from the axis of spin. At the North and South Pole a small piece of earth has 24 hours to move in a full circle around the axis, which is feet to fractions-of-an-inch per hour (i.e. pretty darn slow). At the equator -- the farthest distance from the axis -- the surface of the Earth is moving at 1670 kilometers/hour (1070 miles/hr).

In other words: at the moment of sudden stop everyone standing at the equator would suddenly find themselves travelling at 1.4 times the speed of sound relative to the now-still surface...at least until they hit something.

And then the real fun starts.

Amongst the things that would still be moving (per Newton's first law of motion) is the atmosphere. Anyone who survived flying sideways at 1000+ miles per hour would quickly realize that they were experiencing the worst wind storm ever imaginable. For context, a category five hurricane has winds of over 249km/h (155 miles/h). Just like the people who went flying, the speed of the air is now 1000+ miles per hour relative to the now-stopped surface. Anything that didn't already go zooming to one side would be getting smashed by crushing wind force...and probably then go flying.

And then there's the fact that about 70% of the Earth's surface is water -- which is also not anchored. The shift in momentum would yield enormous tsunamis, which would probably be even worse due to the aforementioned raging windstorm.

There's yet one more liquid we'd have to be concerned with: all of the magma constantly moving through the Earth's mantle and core. I'm not sure whether the magma stops moving suddenly with the solid earth or it stays moving -- but assuming it's still moving*, that would most likely lead to volcanic eruptions through every channel possible to the surface...and there would be earthquakes that go with that.

So, yeah. Stuff would move.
What would happen if the Earth stopped rotating? - Quora


*If the magma inside the Earth stopped moving, there'd be another problem: the immediate collapse of the Earth's electromagnetic field and the resulting collapse of the Van Allen Radiation Belt, meaning that assuming you survived the supersonic flight, category who-knows-what hurricane force winds, and walls of moving water...you would sooner or later die from cosmic radiation

Hizi theory ni za uongo, ukiwa kwenye gari lililo wazi unaweza kuruka juu ukakuta gari limekuacha ukadondokea chini, kwa nini isiwe hivyo kwenye dunia?

Ushasema gari lililo wazi manaake unarudishwa nyuma na force ya upepo. Jaribu kupanda ndani ya basi ambalo linakwenda kwa mwendo usiobadilika( coz dunia haibadilishi mwendo) na barabara isiwe na matuta, unaweza kuruka na kutua pale pale, unaweza kurusha mpira juu na kuudaka bila ya mpira kuachwa na mwendo wa gari. unaweza kufanya chochote kile kama upo ardhini tu. Kwako utaona kama gari imesimama na ukichungulia dilishani utaona kama nyumba na miti ndo inatembea.. dunia pia iko hivo. Ukiangalia angani utaona kama jua linaizunguka dunia ila sio kweli ni dunia inazunguka jua ila kwa vile wewe upo ndani ya dunia unaona kama upo pale pale tu. Hata uruke juu vp huwezi kurudi nyuma labda urudishwe na upepo

umeelezea vizuri sana mkuu angalau hta mm nimekuelewa kwenye iloo
ina maana dunia inazungua kwnye muhimili wake kwa speed sana ila sisi hatuwez kujua sababu hamna kitu inacho kindhana nacho njian tofaut na gar ikiwa speed itakutana na upepo na kufanya ss tuone kuwa inatembea

 

[makaveli10]

mtu anat0a p0st kzembe utarushwaje wakati dunia ina cener of gravity ambay0 inavuta v2 vyote kuja chn

Centre of gravity ipo lakini inategema na force iliyotumika kutupa kitu, sasa speed ya dunia halafu isimame ghafla means tutachomoka kwa speed ya dunia.. Chukua hiyo acceleration ya dunia zidisha na uzito wa mtu m1 m1.. Hyo force utakayopata hapo ndio utajua km center of gravity itazidiwa au la. Maana hata rocket zinaruka nje wakat dunani kuna force of gravity, ndege zinapaa angani, ndege wanaruka angani etc

 

[makaveli10]

Mkuu usiombe. Maana dunia inatembea 107,200 km/h. Just imagine gari ikitembea Km 180 kwa saa watu wote humo ndani roho juu juu... So ikitokea dunia ikasimama ghafla wote tutarushwa hukooo, sijui hata tutatua wapi. Labda kwenye jua.

Mkuu itakuwa hatari... Ila umbali wa kurusha tutafautiana.. F=ma kwahyo nguvu ya kuturusha itategemeana na uzito wa mtu x acceleration ya dunia, kwa hyo mabonge watarushwa mbali zaid, sisi vimbau mbau tutarushwa mbali kidogo.. Hahaaa...

 

[makaveli10]

Inafurahisha sana.. Mada hizi huwa mtu anajikuta anafikiria akiwa katika pozi maalum.. Sasa mkuu sijui alikuwa katika pozi gani kati ya pozi zetuu zile..

 

[Kinyungu]

Je, ile momentum iliyokuwepo itaturusha nje ya dunia kama mtu anavyorushwa kwenye kioo cha mbele cha gari?

Hebu jaribu kufikiria unaendesha gari kwa speed 240km/h ambayo madirisha yamefungwa na ndani kuna sisimizi ambaye anaendelea na pilika pilika zake. ukisimama ghafla yule sisimizi atarushwa? Au atahisi chochote?

Hicho ndicho kitakupata ww kama dunia ikisimama ghafla.

Sasa hebu tuone kwa kifizikia:

Dunia ikizunguka na assume na ww kwa sababu upo duniani utakuwa unakwenda kwa speed ya dunia kwa hiyo:

Momentum = Mass x Velocity(Speed)
Mass ya ww kulinganisha na mass ya dunia ni ndogo sana sana so na assume ni 0 Kg ( kama vile mass ya sisimizi kwenye gari yako alivyo na uzito ambao ni kama zero tu)

Sasa M = 0 Kg( uzito wako) x speed ya dunia
Jibu ni kuwa momentum yako itakuwa ni zero kwa hiyo hata dunia ikisimana ni sawa na kusema ww hutahisi chochote maaana ww ni mwepesi mno kulinganisha na uzito wa dunia hivyo hautakuwa na momentum yoyote. Utakuwa sawa tu na yule sisimizi kwenye gari yako uliposimama hakuhisi kitu na ww hutahisi kitu kama dunia ikisimama.

Lakini nimejibu kwa ujumla tu maana dunia ina mizunguko miwili.
1) On its own axis
2) On its orbit

Wewe hujakuwa specific mzunguko gani unaotaka
japo kwa both cases the effect is the same

Ukiwa kwenye gari unakuwa ndani ya gari.lakini duniani hatupo ndani ya dunia bali juu ya dunia("on not in")

 

[madmankache]

ikisimama nashuka napanda mars au venus chaplol! ila kuna argument kuhusu dunia kuwa ni flat na sio duara,wataalam wa mambo hz mkifuatilia hli na mkitudadavulia kwa lugha nyepesi itakuwa poa sana(maana english tuu yenyew inapga chenga sasa english ya kwenye taaluma flani hyo ndo ronaldinho gaucho) kwa nn wajuz hao wanasema ipo flat wana hoja gani?

 

[Kifyatu]

Je, ile momentum iliyokuwepo itaturusha nje ya dunia kama mtu anavyorushwa kwenye kioo cha mbele cha gari?

Nakubaliana na maoni ya simplemind lakini ngoja nifafanue kidogo. Samahani kwa urefu wa hili jibu.

Kuna mizunguuko mitatu ya dunia yetu:

1. Mzunguuko unaotupa usiku na mchana (mara moja kila masaa 24 about the north-south axis).
   
2. Mzunguuko unaotupa majira ya mwaka (kulizunguuka jua, mara moja kila siku 365.25).
   
3. Mzunguuko au m-yumbo wa hii North-South Axis (precessional rotation au the wobbling of the north-south axis) na huchukua miaka 26,000 kwa kila mzunguuko mmoja.

Sasa tuone kitatokea nini kama moja ya mizunguuko hii mitatu itasimama.

Kabla sijaendelea, ni lazima ujue kuwa kuna kanuni za fizikia kuhusu mizunguuko. Kanuni muhimu ni kuwa kitu kinachotembea kitaendelea kutembea mpaka kikutane na nguvu itakayokisimamisha au kubadili muelekeo wake. Swali lako linakosa mashiko kwa sababu hicho kitu (au dhoruba) kitakachotusimamisha ghafla kitamaliza uhai wote hapa duniani kwa hiyo haileti maana kuulizia kuwa sisi tutaathirika vipi. Ni sawa na kuuliza kitatokea nini kama unasafiri kwenye gari (la wazi au lililofunikwa) kwa kasi ya 200 km/saa na ukagonga ukuta au mwamba. Lakini, just as a non-serious academic exercise, ngoja nijibu.

1. Kusimama kwa mzunguuko wa kwanza:
Kwanza mabadiliko ya uhakika ya usiku na mchana yatakoma. Pili, tutayumba kwa sababu ile stability inayoletwa na huu mzunguuko (gyroscopic stability haitakuwepo tena). Kwa hiyo ingawaje hatutakuwa na mabadiliko ya uhakika ya mchana na usiku lakini majira yetu (kiangazi, vuli/masika) havitakuwepo. Jet stream itasimama na kuharibu kabisa hali ya hewa.

2. Kusimama kutolizunguuka jua.
Kama mkuu simplemind alivyosema tutadondoka kama embe kuelekea kwenye jua. Dunia yetu ni kama satelite ya jua. Tunabakia kwenye orbit yetu kwa ajili ya huu mzunguuko. Kama ilivyo tunapotaka kudondosha satelite zetu tunapunguza kasi yake basi itakuwa hivyo hivyo kwa dunia. Tutaangukia kwenye jua na hapo mchezo ndio utakuwa umekwisha.

3. Kusimama kwa precessional rotation (au Gyroscopic Precession).
Kwa wale wanaofuatilia maswala ya unajimu (Astrology) watajua kuwa Spring au Vernal Equinox (siku ambayo urefu wa usiku na mchana ni sawa) hutokea March 20 na wakati huo jua linakuwa kwenye mkusanyiko wa nyota (constellation) wa Pisces (au Samaki). Lakini kwa ajili ya hii Gyroscopic Precession, kila baada ya miaka 2,150 jua linahamia constellation nyingine (kutoka Pisces, to Aquarius, to Capricorn, to Sagittarius, to ...). Sasa hivi jua linapaswa kuwa limehamia kwenye constellation ya Aquarius (Maji). Huu mzunguuko utaendelea kubadili jua litakapokuwepo (constellation) na utaendelea kwa miaka 26,000 ili kurudi ulipoanzia. Soma zaidi kuhusu AGE OF AQUARIUS hapa - Age of Aquarius - Wikipedia, the free encyclopedia.

Sasa kama huu mzunguuko (gyroscopic precession) ukisimama basi siku zote Spring Equinox ikitokea jua litakuwa kwenye constellation moja tu na haitabadilika kamwe. Hii ina serious astrological implications ambazo sitazielezea zaidi. Pengine nimekwisha wapoteza wengi na hiyo sio dhamira yangu.

Mkuu neo1 upo lakini? Usiniulize swali la kinajimu tu.
