Yintoni na - weightlessness?

Weightlessness - i imeko apho umzimba uzive inkxaso reaction. Ukuze ufumane inkcazelo engakumbi malunga nokuba yintoni na apho awavakalelwa ngayo, kwaye kuya kuxoxwa ngazo kweli nqaku.

static

Kukho iindidi ezimbini weightlessness. Le static - kukho umgama ukusuka into mass enkulu. Umzekelo, umzimba, bantinga ukuya kumgama kakhulu ukusuka emhlabeni. Kufuneka kuqondwe ukuba ubunzima akuthethi ziphele ngokupheleleyo.

Isibakala sokuba ubunzulu izinto ezinkulu, ezifana langa neenkwenkwezi, nangona, kwaye unciphisa kunye umgama, kodwa ziphele ngokupheleleyo. Action ithanda ezingenakuphela kude kuzo zonke iimbombo iphela, bomzimba ngokomlinganiselo isikweri umgama. Oku kulandela kule nkcazelo weightlessness.

Ngenxa yoko, ukuba uphume ummandla asendle omxhuzulane akunakwenzeka.

yidityaniso olutshintshatshintshayo

Olunye uhlobo weightlessness - onamandla. Its rhoqo amava oosomajukujuku pilot. Yokungenelela isenzo asendle omxhuzulane kunokuba into enkulu khulula esiwa kuyo. Ukwenza oku, injongo wazuza ngesantya ethile waza waba neqabane.

Ukudayela ngesantya efunekayo, i-satellite iqala ukuya ukwimeko rhoqo ukuwa. Izinto ngaphakathi kuya kuba kwimo weightlessness. Le isantya kuthiwa indawo yokuqala.

Kuba Earth, umzekelo, izinga imalunga-8 km ngomzuzu. Kuba Sun - sele 640. Konke kuxhomekeke ubunzima into mninzi yayo. Xa into indawo enjalo apho lexinene ufikelela amakhulu ezigidi zeetoni sentimitha cc - le Velocity isithuba osondela isivamvo sokukhanya.

Weightlessness on Earth

Kubonakala ukuba sinjani isimo weightlessness, ngaphandle kokushiya imida ye planethi. Noko ke, ixesha elifutshane kakhulu. Umzekelo, umkhweli isithuthi ekhwele phezu ibhulorho enhle, uvavanyo weightlessness ixesha elithile phezu convexity ye kwebhulorho.

Abakhweli abahambahambayo izithuthi zikawonke kwindlela benqumla, ngokuxhomekeke rhoqo kwi intshukumo isimaphambili se weightlessness ixesha nganye ibhasi lube emhadini okanye bamba. Ixesha elifutshane nexesha zikwimeko yokuwa free.

nokuzonwabisa

Kutshanje, yeepoligoni ezikhethekileyo wabonakala kushishino lokonwabisa, apho wonke umntu abone weightlessness.

Ekubeni uluphumelele uvavanyo lonyango kunye nokuhlawula isixa esithile semali, ungafumana ababekhwele kweso moya, nto leyo ephaphazela emendweni yeNyoka, kwaye ngexesha incopho yabantu ngaphezu kwesiqingatha ngcaciso emfutshane ukuze babe imvakalelo angaqhelekanga weightlessness.

Le selinge moya ngokusebenzisa intercom isaziso ekuqaleni weightlessness. Oku kuyimfuneko ngenxa yezizathu zokhuseleko. Inyaniso kukuba emva ezamahala kokuwa moya ukuzuza ngokukhawuleza ukuphakama. Kodwa ngabantu ababekhwele, nazo isiphumo iphambene malunga - overload.

Ngamanye amaxesha eli xabiso ixesha emithathu ifikelela ixabiso ukukhawulezisa omxhuzulane. Ngamanye amazwi, ubunzima inomzimba weightlessness iya kuba kathathu kuyazenzekela. Uwa evela ukuphakama kuyimitha eziliqela ezinobunzima ingakhuphela ngokulula kakhulu ndenzakale.

Ukulungiselela le njongo kwi-moya ehleli e-ofisini abahlohli abaqeqeshwe ngokukodwa weightlessness. umsebenzi yabo ixesha ukuthoba ku moya osezantsi abo bantu Andinaxesha ukugcina ngexesha lekhefu elinikiweyo.

Uthotho amahla ndinyuka kwenzeka emva kwesithuba ngokuphindwe amabini kwelinye ukubhabha moya.

ERashiya, umzekelo, abo banqwenela ukuba i weightlessness of a icentrifuge olulodwa, nto leyo ifumaneka kwi Cosmonaut Training Centre kunye pilot. Kwakhona, emva kokuba ufumene uvavanyo lonyango kunye nemali igalelo kwi-mali ka-55 amawaka. Engange umntu va ifuthe weightlessness.

Ifuthe emzimbeni womntu

Xa inkcazelo, weightlessness akuyongozi ngokupheleleyo emzimbeni womntu. kuvela ubunzima xa ihlala iintsuku eziliqela, iiveki okanye iinyanga.

Kwiimeko ezininzi, oku kusebenza kuphela abahlali station isithuba. Oosomajukujuku, kuba ixesha elide ababekhwele izithuthi uqala ukubona ubuhlungu ebalulekileyo. Oku kubangelwa ikakhulu ukuya indlela vestibular.

On Earth, kwindawo eqhelekileyo, i otoliths ze izixhobo vestibular ibeka uxinzelelo phezu kwalapho, nto leyo eyabangela ingqondo zethu, apho phezulu nasezantsi, eqondisa umzimba womntu emajukujukwini.

Weight kunye weightlessness

Kuyinto enye xa umzimba abulinganise nto. Zonke iinkqubo zenzeka kulo kunjalo. Ngenxa yokungabikho xi lwenzeka nokudideka otolith emajukujukwini. Le mbono "phezulu" yaye "phantsi" emajukujukwini ubalekela ngokupheleleyo. Ichitha umzimba womntu yokunqongophala eyahlukahlukeneyo. Kule meko, izihlunu yoma, ukuba akukho manyathelo kuthathwe. Ukuhlupheka kunye nokuthotywa yethishyu ithambo. Xa kungekho mthwalo ikhutshwa kwi yomzimba ngaphantsi phosphorus.

Unobunzima yokuginya ukutya kunye nolwelo. Zonke ulwelo xa efuna ukuthatha imilo ungqukuva, apho kunzima kakhulu kwizinto zemihla ngemihla. Nditsho abandayo eqhelekileyo kwiimeko ikhaphukhaphu kunokuba uvavanyo nzima kakhulu ukuba eziphilayo ngenxa yokuba isikhohlela kungaveli phantsi amanyathelo womxhuzulane, yaye zamathontsana ukulenza.

Ukugcina oosomajukujuku isandi kuyimfuneko rhoqo ukuqeqesha iiyure eziliqela ngosuku. Ngexesha lokulala tie ne iirholithi ezikhethekileyo ukuthintela ukwenzakala ngexesha ubuthongo.

Ukuze amandla oosomajukujuku liphuhlise ukutya ekhethekileyo iityhubhu kunye nesonka ongavelisi ukuwa.

Phambi elide amava weightlessness, umntu kufuneka uzive inyathelo layo phezu komhlaba uku bana phandle njani kwixesha elizayo kuya kuchaphazela ukungabikho womxhuzulane.
