Kungani inyanga angawi kuze hlabathi? ukuhlaziywa enemininingwane

Lesi sihloko sichaza ukuthi kungani inyanga akusho kuwele phansi, kudala ukunyakaza Zomhlaba namanye izici Mechanics yasezulwini yesimiso sethu sonozungezilanga.

Ukuqala engu isikhala

satellite zendalo wethu njalo amehlo. Endulo, inyanga ibilokhu isihloko cult zezinkolo ezithile, futhi kokusungulwa izibonakude bakudala izazi zezinkanyezi zokuqala ayikwazanga likhiphe yena kude nokucabanga asemigodini ngokubabazekayo.

Ngemva nje kancane kwalokho, nge mbobo nezinye izindawo yezinkanyezi, kwaba sobala ukuthi isiphuphutheki yasezulwini esinjalo kubaluleke kakhulu kule planethi yethu hhayi kuphela, kodwa futhi eziningi kwabanye. Futhi i-Jupiter, njengoba abaningi 67 izingcezu! Kodwa umholi wethu ubukhulu ohlelweni lonke. Kodwa kungani inyanga angawi kuze hlabathi? Siyini isizathu lokuya kwaso eduze orbit efanayo? Yilokhu sizoxoxa.

Mechanics yasezulwini

Ukuze uqale, kudingeka ukubhekana neqiniso ukuthi hambisa ngaphakathi wo orbit enjalo, nokuthi kungani kwenzeka. Ngokwe-definition esetshenziswa ama-astronomer kanye Physics, orbit - movement in emkhakheni adonsela phansi ezinye, kakhulu baphakame mass into. Kwaphela isikhathi eside kwakucatshangwa ukuthi uzungeza amaplanethi iziphuphutheki abe ukuma isiyingi njengoba zemvelo kakhulu futhi ephelele, kodwa Kepler, ngemva kwemizamo akuphumelelanga ukusebenzisa lo mbono ukuze ukunyakaza Mars, wakwenqaba.

Njengoba sazi physics Yiqiniso, yiziphi izinto ezimbili uhlangabezana mutual Luhambo amabutho, okuthiwa adonsela phansi. Amabutho efanayo ezithinta umhlaba wethu inyanga. Kodwa uma basuke bakhangwa, kungani inyanga akusho kuwele phansi, njengoba kungaba enengqondo kakhulu?

Into wukuthi Umhlaba owujami, kodwa ihamba ilanga i lesiyingi, kunjengokungathi njalo "uyabaleka" kumngane wakhe. Futhi lokho, yiba isivinini inertial, ngenxa yalokho luhamba orbit futhi okweqanda.

Isibonelo kakhulu elula, okungase ukuchaza lesi simo, kuba ibhola ezintanjeni. Uma nokulikhuthaza, lo amandla centrifugal lizobamba into e indiza ezahlukene, futhi lapho ukubambezela, ngeke kwanele futhi ibhola ngeke lehle. Amabutho efanayo isinyathelo enyangeni. amandla adonsela phansi eMhlabeni udonsa ke emva kwakhe, ukuba uphilele bama phuhle, futhi ibutho centrifugal athuthukile ngenxa ukujikisa, yombango ngaphandle kokunikeza yokusondela ibanga ezibucayi.

Uma umbuzo kungani Moon akusho kuwele phansi, alethe ngisho incazelo elula, isizathu salokhu - umuntu olingana nokuxhumana amabutho. Iplanethi yethu edonsela satellite, okubangela Ukujikeleza yayo futhi amandla centrifugal njengoba odlulela.

ilanga

Le mithetho akusebenzi kubantu kuphela iplanethi yethu satellite, angaphansi zonke ezinye izinto isikhala. Ngokuvamile, amandla adonsela phansi - ngesihloko ethakazelisa kakhulu. achaza ukuhamba kwamaplanethi azungeze maphakathi mass ngokuvamile kuqhathaniswa indlela clockwork, kuba eqondile ngakho futhi kwaqinisekiswa. Futhi okubaluleke kakhulu, kunzima kakhulu ukuphazamisa. Ngisho noma kokuyikhipha amaplanethi eziningana, ezinye awokuthi kakhulu, ukujayela orbit entsha, bese uyivala kuwa inkanyezi emaphakathi ngeke kwenzeke.

Kodwa uma inkanyezi yethu inethonya okudonsa omkhulu kangaka ngisho izifundo ezikude kakhulu, kungani Moon angawi elangeni? Yiqiniso, lenkanyezi kude kakhulu kunalokho lonke eMhlabeni, kodwa isisindo salo, futhi ngenxa yalokho yesisindo iphezulu kakhulu.

Into wukuthi nendikimba ethile esemkhathini nomngane wakhe nazo nomjikelezo wawo emhlabeni Sun, kanti isixuku esikhulu engathathi isinyathelo yedwa inyanga nomhlaba, futhi isikhungo sabo ezivamile mass. Inyanga umphumela double gravity - izinkanyezi namaplanethi, futhi ngemva kwakhe, futhi ibutho centrifugal ukuthi ilinganisa kubo. Uma kungenjalo, zonke kumasathalayithi nezinye izinto kufanele eside ngabe niyishise inkanyiso ashisayo. Yileyo impendulo yombuzo othi njalo kungani Moon angawi.

ukuhamba Sun

Enye kokukhuluma kuwufanele iqiniso lokuthi Sun nakho ezihambayo! Futhi kanye, futhi uhlelo lwethu lonke, nakuba sivame ucabange ukuthi isikhala uzinzile futhi zingashintshi, ugcine uzungeza iplanethi.

Uma ubheka kabanzi emhlabeni jikelele phakathi kohlaka izinhlelo kanye namaqoqo lonke zemithala, singabona ukuthi nabo ukuhambisa e trajectories yabo. Kulokhu, lo Ilanga "iziphuphutheki" yayo lumayelana enkabeni yalo mthala -Milky Way. Uma kunemibandela ukwethula lesi sithombe kusuka ngenhla, kubukeka sengathi i-Kuvunguza nge eziningi amagatsha, ababiziweyo izingalo Galactic. Kwenye yalezi imikhono, kanye nezigidi zabanye izinkanyezi, Sun yethu iphokophele, futhi.

falling

Nokho, uma ubuza lo mbuzo, futhi baphuphe? Yiziphi izimo ezidingekayo Moon ngabe iphahlazeke ngaphansi kwazo ku Earth noma ukuthatha uhambo ukuze ilanga?

Lokhu kungenzeka uma isiphuphutheki uyayeka uzungeza into esemqoka kanye centrifugal force ubalekela, sengathi orbit yinto ushintsho kakhulu bese wengeza isivinini, isibonelo, ukushayisana komhlaba emkhathini.

Kodwa inkanyezi kuzoqhubeka, uma okubhekiswe ngandlela-thile ukuze ayeke ukuhamba kwayo emhlabeni Earth futhi anikeze ukusheshisa okuqala inkanyiso. Kodwa cishe, inyanga bayovuka kancane kancane kuphela entsha orbit lwalugobile.

Ngamafuphi: inyanga akusho kuwele phansi ngoba, ngaphezu Luhambo le planethi, kanye centrifugal force enza elikushoyo, ukuthi kungaba ke njengoba oxosha. Ngenxa yalokho yale miphumela ezimbili silinganise nomunye, satellite akusho ngimuke eshayisa ku iplanethi.
