Iqiniso lokuthi yesisindo izinto ezinkulu, ezifana amaplanethi nezinkanyezi, Nokho, kunciphe nge ibanga, kodwa ingabe usekhona ngokuphelele. Isenzo ubabonisa yayo ngokungenamkhawulo kude kuwo wonke amagumbi nasemhlabeni, inhlukanozigaba esikweleni yebanga. Ngakho kusukela kwencazelo weightlessness.

Ngakho, ukuze uthole aphume okudonsa ensimini zone akunakwenzeka.

ashukumisayo

Olunye uhlobo weightlessness - onamandla. njalo layo ukuzwa osomkhathi nama-pilot. Iwukudambisa isenzo yasendle okudonsa kungaba into omkhulu ngokufaka khulula ehlela phezu kwalo. Ukuze wenze lokhu, into yazuza isivinini ethile futhi waba umngane.

Ukudayela isivinini oyifunayo, satellite uqala ukunyakaza esimweni njalo ngokuwa khulula. Izinto ngaphakathi kuzoba esimweni weightlessness. Lokhu isivinini ibizwa ngokuthi isikhala kuqala.

Ngomhlaba, isibonelo, izinga imayelana 8 amakhilomitha ngomzuzwana. Ukuze Sun - kakade 640. Konke kuncike nenqwaba into kanye kwabantu bayo. Ngo into enjalo isikhala lapho inhlanganiso ifinyelela amakhulu ezigidi amathani angu isentimitha cubic - the velocity isikhala osondela ngejubane lokukhanya.

Weightlessness Emhlabeni

It kuvela ukuthi ungathola isimo weightlessness, ngaphandle kokushiya ukulinganiselwa iplanethi. Nokho, isikhathi esifushane kakhulu. Ngokwesibonelo, umgibeli imoto ugibele kwebhuloho arched, ukuhlolwa weightlessness isikhashana phezu convexity ngayo leli bhuloho.

Abagibeli abajikelezayo izithuthi zomphakathi kwi umgwaqo bumpy, njalo kuncike isenzo weightlessness isikhathi ngasinye ibhasi siphela emgodini noma iqhubu. Ukuze uthole isikhathi esifushane asesikhundleni isimo mahhala ukuwa.

ukuzijabulisa

Muva nje, ngemapholigoni ekhethekile uvele imboni yezokuzijabulisa, lapho wonke umuntu angakwazi ukuzwa weightlessness.

Bephumelele lapho ngihlolwa kanye ukukhokha isamba esithile semali, ungathola ku ndiza, okuyinto endiza indlela oyinyoka, futhi phakathi isiqongo lwabantu abangaphezu kwesigamu somzuzu bangezwa umuzwa ongavamile weightlessness.

Umshayeli wendiza indiza intercom wamemezela ukuqala weightlessness. Lokhu kuyadingeka ngenxa yezizathu zokuphepha. Iqiniso liwukuthi emva khulula ukuwa indiza ngokushesha ukuthola kokuwa. Kodwa abantu ebhodini, uhlangabezana nomphumela akuhambisani okuphambene - sindisa.

Ngenxa yale njongo indiza ehlezi ehhovisi abafundisi abaqeqeshwe ngokukhethekile ukuze weightlessness. umsebenzi wabo isikhathi wehlise indiza phansi kwalabo bantu abangenayo isikhathi ukugcina ngaphakathi ngesikhathi esinikeziwe.

Uchungechunge ube nezikhathi ezinzima nezimnandi kwenzeke ngezikhawu izikhathi kuze kufinyelele amabili zindiza omunye izindiza.

ERussia, isibonelo, kulabo abafisa ukuzwa weightlessness we Centrifuge ekhethekile, okuyinto Itholakala Cosmonaut Training Centre kanye abashayeli bezindiza. Nalapha futhi, ngemva ngihlolwa kanye umnikelo imali nenani lawo lalingaba zinkulungwane 55. Ruble umuntu bangazizwa umphumela weightlessness.

Emhlabeni, endaweni abayijwayele, otoliths we-apharathasi vestibular acindezele eziyimpumelelo emsipheni, ngaleyo ndlela esibatshela ubuchopho bethu, lapho phezulu futhi phansi, siqondise umzimba womuntu emkhathini.

Isisindo kanye weightlessness

Kanti kungokunye uma umzimba akusho nesisindo lutho. Zonke izinqubo zenzeka noma kunjalo. Ngenxa yokuntuleka ingcindezi kwenzeka disorientation otolith emkhathini. Umqondo "etulu" na "phasi" emkhathini ubalekela ngokuphelele. It ilimaza umzimba womuntu njengoba zingenzi lutho olunyakazisa umzimba. Kuleli zinga, imisipha yoma, uma kungekho senzo esithathwayo. Nge ukuhlupheka kwakhe nokwehliswa kwesithunzi ithambo izicubu. Uma kungekho umthwalo ihlinzekwa e ithambo umzimba kancane phosphorus.

Unenkinga ukugwinya ukudla uketshezi. Zonke uketshezi lapho efuna ukuthatha ukuma eyindilinga, okuyinto okunzima kakhulu ngezinto zansuku zonke. Ngisho umkhuhlane ezimweni isisindo kungaba uvivinyo olukhulu kakhulu umzimba ngenxa yokuthi isikhwehlela kungaveli ngaphansi isenzo adonsela phansi, futhi yakha amaconsi eyindilinga.

Ukuze silondoloze kudingekile ithoni osomkhathi njalo ukuqeqesha amahora ambalwa ngosuku. Ngezinye sokulala ibophelana nge ezizibeni ezikhethekile zokugwema ukulimala ngesikhathi sokulala.
