Astrophysics. Kungani inyanga akusho uphendukisa emhlabeni axis awo?

Inyanga akusho uphendukisa emhlabeni eksisi kabhontshisi Lokhu kuyiqiniso? Kwaphela iminyaka eminingi ososayensi bathi ngale ndaba, kodwa impendulo ukuthi ngabe ukwanelisa wonke umuntu, abatholi. Ngamunye kuletha imicabango yabo futhi bazame ukubonisa ukuthi kubo. Kuze kube manje, kukhona isimo impikiswano mayelana nalokhu.

Ukuma of the Moon

Tadisha ebusweni kwenyanga Sinesithakazelo esikhulu kule wezesayensi. cwaningo wayo wenziwa ngokuhlanganyela ezinye Earth, ucabangela njengoba uhlelo linye.

Lapho Moon kwenza sayo emhlabeni Earth, isikhundla salo isihlobo ukuba ilanga zishintsha. Ngu ebhekene iplanethi yethu ihlale ecaleni elifanayo yalo. Umugqa ukuthi uhlukanisa nengxenye, ebizwa ngokuthi isinqamuli. Njengoba inyanga - inyanga, ke ujikeleza, akha i ellipsoid.

Phakathi endleleni yayo emhlabeni Sun, kubonakala sengathi ohlangothini Illuminated zenyanga eshintsha ukuma. Nokho, nendikimba ethile esemkhathini uhlale round, kodwa ngenxa ukushintshashintsha engela kwesifo kwelanga phezu kubonakala sengathi njengoba injalo ishintshile. Ingakapheli inyanga the Moon kubonakala Umhlaba ngezindlela eziningana ezahlukene. Khona-ke abakhululiwe eziyinhloko:

• kokuthwasa kwenyanga;
• kwikota yokuqala;
• Inyanga egcwele;
• ikota zokugcina.

Lapho kwenyanga Inyanga esibhakabhakeni ayibonakali, njengoba le oluhambisana indawo satellite phakathi kwelanga nomhlaba. Ukukhanya eLangeni, iNyanga angawi, futhi ngenxa yalokho, yini bounces, ngakho hhafu it njengoba kubonakala eMhlabeni, engamboziwe.

Kwikota yokuqala zikhanyiswa ilanga kwesokudla uhhafu inyanga, njengoba kuba ibanga emincane ye-90 ° ukusuka elangeni. Esikhathini engxenyeni yokugcina Isimo siyefana, ohlangothini lwesobunxele kuphela esikhanyayo.

Kuyeza isigaba sesine - edilingene, inyanga ephikisana ne Sun, khona kuzoveza ngokugcwele ukukhanya ehlela phezu kwalo, futhi Umhlaba wazibona zonke isigamu esikhanyayo.

umhlaba

Emuva ekhulwini le-16 kwakutholakala ukuthi Umhlaba has Ukujikeleza lalo. Nokho-ke waqala futhi yini kwalesi, akwaziwa. Kulesi senzakalo, kunezinkolelo-mbono eziningi. Ngokwesibonelo, ukwakheka kwamabala amaplanethi uthuli amafu exhunywe wasungula iplanethi ngesikhathi esifanayo basuke bakhangwa nezinye izidumbu cosmic. Clash of amaplanethi nalezi emizimbeni angabanga bathuthe, bese kwenzekani inertia. Lona omunye imicabango, uye ayitholakalanga isiqinisekiso ecacile. Kule ndaba, kukhona omunye umbuzo: kungani inyanga akusho uphendukisa emhlabeni axis awo? Ake sizame ukuphendula.

Izinhlobo Ukujikeleza kwenyanga

Imfuneko ukuthi umzimba ungakwazi ukushintshanisa azungeze axis awo siqu, kuyinto khona kwale-eksisi, nenyanga akuyona. Ubufakazi lokhu ethulwa ngesimo esilandelayo: Inyanga - lokhu umzimba, sizobe ihlukaniswe inani elikhulu amaphuzu. Lapho ukujikisa, migomo ukuchaza trajectory ngesimo ezinephakathi elilodwa. Okungukuthi, kuvela ukuthi ababandakanyeka ukujikeleza zonke. Futhi uma une ezinye amaphuzu eksisi wawuyohlala fixed, futhi sibonakala kuthabathela ecaleni Umhlaba kwakuzoshintsha. Lokhu akusho kwenzeke.

Ngamanye amazwi, amabutho centrifugal lapho siqondiswa ukuba isikhungo, azikho satellite, ngakho Moon akuyona ukuphotha.

yasezulwini ukunyakaza komzimba

Nihlola ukujikeleza efanele zenyanga, izazi zesayensi zisebenzisa izindlela ezihlukahlukene. Omunye wabo kuhlolwe ukunyakaza Zomhlaba satellite isihlobo ukuba izinkanyezi.

Basuke bathathwa umzimba umile, okuyinto uragele phambili. Ukusebenzisa le ndlela, kuvela ukuthi Ukujikeleza yayo ehlobene izinkanyezi khona satellite. Kulesi samuntu, lapho umbuzo kungani inyanga akusho uphendukisa emhlabeni axis awo, impendulo izawulalelwa, ukuthi ihamba. Nokho, la mazwi akulona iqiniso. Kusukela Ukuphathwa zenyanga kunqunywa centripetal Umhlaba ke zicinge sehlangano wasezulwini kufanele kube isihlobo ukuba Earth.

Orbit noma trajectory

Ukuze uthole ukuthi ngabe Moon uzungeza kuma-axis awo azungeze, cabanga imiqondo ezifana "orbit" futhi "trajectory". Ziyahlukahluka kuye.

wokuzungeza:

• ijika avaliwe;
• balolonge - round noma okweqanda;
• Ihlala e endizeni;

trajectory:

• ijika kokuba unesiqalo nesiphetho;
• iqonde noma lwalugobile;
• It etholakala ngayo indiza noma unhlangothi-ntathu.

Kungani inyanga akusho uphendukisa emhlabeni axis awo? Kuyaziwa ukuthi umzimba ongabamba iqhaza ezimbili kuphela izinhlobo ezinyakazayo kanyekanye. Inyanga, lezi zinhlobo ezimbili evumelekile abakhona: emhlabeni Earth ilanga. Ngakho, ezinye izinhlobo Ukujikeleza kungaba.

Uma ubheka trajectory of the Moon kusukela Earth, sibona ijika eziyinkimbinkimbi.

Ukuba khona emzileni kuphethwe umthetho ukulondolozwa umfutho, kodwa singashintsha, uma mina ukushintsha umfutho. Orbit - esachazwa imithetho yemvelo, trajectory - imithetho wezibalo.

Umhlaba-Moon uhlelo

Ezinye izinzuzo Moon ne-Earth - kuyinto uhlelo esinobunye lonke. Izibalo ibalwa zabo ezivamile maphakathi mass, okungadingi uqondane maphakathi Earth, futhi wawuthi ukujikeleza kwenzekani endaweni emzungezile. Nokho, kusukela iphuzu Ngenxa isayensi yokuma kwezinto ezisemkhathini, iyiphi azungeza kwalesi sikhungo ayitholakali, okungase kunqunywe ngokuqapha Moon Nomhlaba ngokusebenzisa imishini ekhethekile.

Kungani inyanga akusho uphendukisa emhlabeni axis awo? Ingabe kuyiqiniso lokhu? Ukujikeleza komhlaba nendikimba esemkhathini iyona spin-spin futhi spin-orbit. Moon wenza ukujikeleza ezinyakazayo spin-esemkhathini mayelana-eksisi edabula maphakathi Earth.

Abantu Emhlabeni ukubona sonke isikhathi uhlangothi zenyanga, futhi akashintshi. Ukuze uthole ubufakazi ezingokoqobo ongabonisa ukuqhuba thizeni izinsimbi ezincane.

Thatha slug, ubophele yona ngentambo twist. Kulokhu, nenyanga ngeke lehle, bese umuntu enaleyo kube komunye umkhawulo intambo - Earth. Izungezisa okuzungezile slug, umuntu ubona uhlangothi olulodwa wakhe, ukuthi itholakala emhlabeni kubantu ukubona uhlangothi zenyanga. Asondela kule ndoda yesibili, owaba ibanga, bheka nxazonke izinsimbi neqiniso lokuthi awusebenzi uphendukisa emhlabeni axis awo. Inyanga into efanayo kwenzeka, khona-ke aluphumeleli uphendukisa emhlabeni axis awo.

isikhala yobudala

Kwaphela isikhathi eside ososayensi behlola kuphela ohlangothini ebonakalayo zenyanga. Kwakungekho indlela yokwazi ukuthi kubukeka sengathi okuphambene. Kodwa nge ukuthuthukisa engu isikhala phakathi nekhulu lama-20, isintu siye sazama ukubona enye inhlangano.

Kwabe sekuvela ukuthi, Nenkabazwe kwenyanga zihluke kakhulu nomunye. Ngakho, surface ecaleni ebhekene Umhlaba embozwe nezinkezo basalt, futhi ebusweni hemispheric yesibili cratered. Lezi umehluko namanje sivuse isithakazelo ososayensi. Kukholakala ukuthi eminyakeni eminingi edlule kwase kunezinto ezimbili okufanele iziphuphutheki Zomhlaba, elinye lawo lishayisana Moon futhi washiya imprints yayo ebusweni enjalo.

isiphetho

Luna - ogama ukuziphatha akuyona ncamashi ezaziwayo. Kungani inyanga akusho uphendukisa emhlabeni axis awo? Lo mbuzo owabuzwa ososayensi abaningi iminyaka eminingi futhi oyingqayizivele lengiyo ayitholakali. Abanye ososayensi bakholelwa ukuthi ukuzungeza sisekhona, kodwa engabonakali kubantu, ngoba isikhathi Moon ujikeleza uzungeze axis awo kanye emhlabeni Umhlaba efanayo. Ezinye izazi ukuphika lokhu futhi aqaphele nokuncenga inyanga isiseduze Sun Nomhlaba.

Umbuzo othi kungani inyanga akusho uphendukisa emhlabeni axis awo, waba okuxoxwe ngazo kulesi sihloko, futhi ngendlela isibonelo (mayelana slug) kubonakaliswa.
