Kutheni nenyanga ziwe emhlabeni? Uhlalutyo olunzulu

Eli nqaku lichaza isizathu sokuba nenyanga ziwe emhlabeni, ibangela ngentshukumo zoMhlaba kunye nabanye eminye iinkalo ubucukubhede yasezulwini wezijikelezi-langa.

Ukuqala nangobudala kwisithuba

satellite Natural iplanethi yethu belisoloko itsale ingqalelo. Kumaxesha amandulo, inyanga iye yaba ngumba ihlelo kwezinye iicawa, kwaye kwasungulwa ngeeteleskopu zamandulo ngeenkwenkwezi yokuqala ayikwazanga kubukrazula ngokwakhe ukusuka Eyokuqiqa ka yimingxuma iyingangamsha.

Kamva, kunye baqhaqhe kwezinye iindawo ngeenkwenkwezi, kwaye kwacaca ukuba satellite yasezulwini enjalo iplanethi yethu nje kuphela, kodwa iqela abanye. Eziqwenga Jupiter, ngangoko singako thina 67! Kodwa nenkokheli zethu ubungakanani kwinkqubo yonke. Kodwa kutheni nenyanga ziwe emhlabeni? Yintoni na isizathu nentshukumo yayo ecaleni komzila efanayo? Le nto iya kuthetha.

ubucukubhede zasezulwini

Ukuze uqale, kufuneka ukumelana nento yokuba ukufuduka emzileni wawo, yaye kutheni oko kwenzeka. Ngokutsho nkcazo esetyenziswa yi izazi kunye Physics, orbit - intshukumo kule intsimi omxhuzulane enye, mkhulu kakhulu mass le into. Ukuze ixesha elide kwakucingwa ukuba zisuke-langa satellites i imilo setyhula kakhulu zendalo egqibeleleyo, kodwa Kepler, emva kwempumelelo ukusebenzisa le theory isindululo Mars, bawucekisile.

Njengoko sisazi kwikhondo physics, naziphi na izinto ezimbini abafumana efanayo imikhosi umtsalane, ebizwa ngokuba yi-womxhuzulane. Imikhosi yolawulo efanayo kuchaphazela iplanethi yethu nenyanga. Kodwa ukuba bathanda, kutheni nenyanga ziwe emhlabeni, njengoko bekuya kuba enengqondo kakhulu?

Eyona nto kukuba Umhlaba awumi ndawonye kodwa ihamba ilanga in an ellipse, njengokuba kunjalo, rhoqo "ebaleka" neqabane lakhe. Kwaye, yena, ube isantya inertial, ngenxa yoko ohamba orbit kwakhona okweqanda.

Owona mzekelo elula, nto leyo ukubaqononondisa lo meko, ibhola phezu kwentambo. Ukuba ukuyikhuthaza, le amandla centrifugal ziya kubamba into moya ezahlukeneyo, yaye nini ukuba isantya, akuyi kuba ngokwaneleyo kwaye ibhola iya kunyothulwa. Imikhosi yolawulo efanayo sithathele enyangeni. bekukubi koMhlaba ukurhuqa emva kwakhe, ukungavumeli ukuma ngxi, yaye amandla centrifugal zaphuhliswa ngenxa ujikelezo, yenza, ngaphandle kokuba indlela ukuya kumgama ezibalulekileyo.

Ukuba umbuzo kutheni iNyanga ayikho ziwe emhlabeni, ngisho ngaphezulu ingcaciso elula, isizathu soku - imikhosi intsebenziswano ngokulinganayo. iplanethi yethu ezitsala satellite, ebangela ujikelezo yayo kunye nomkhosi centrifugal njengoko pushes.

ilanga

Le mithetho isebenza kuphela ukuba umhlaba wethu satellite, ukuba kuxhomekeke kuzo zonke ezinye izinto isithuba. Ngokubanzi, benokundileka - isihloko umdla kakhulu. motion yemihlaba emhlabeni kumbindi ubunzima idla kuthelekiswa kwindlela clockwork, ukuba zichanile kwaye zingqinisiswe. Kwaye okona kubalulekileyo, kunzima kakhulu ukuba ukuphazamisa. Nokuba ukuba uyayisusa evela iiplanethi eziliqela, enye kunye namathuba eliphezulu kakhulu, ukuba ziqhelane komzila entsha, baphele kunye ukuwa kwenkwenkwezi engundoqo akayi kwenzeka.

Ke ukuba inkwenkwezi zethu elikhulu enjalo omxhuzulane nkqu ezi zifundo zikude, kutheni iNyanga angawi iLanga? Kakade ke, inkwenkwezi leyo kumgama phi kwe Earth, kodwa ubunzima bayo, yaye ngoko kokona iphezulu kakhulu.

Le nto yokuba umzimba yasezulwini kunye neqabane lakhe umlomo xa ijikeleza iLanga, kwaye yokugqibela akenzi yedwa kwi inyanga kunye nomhlaba, yaye iziko wabo oqhelekileyo mass. Kwaye ke inyanga isiphumo kabini womxhuzulane - iinkwenkwezi nezinye izijikelezi, yaye emva kwakhe, nomkhosi centrifugal ukungqinelana kwabo. Kungenjalo, zonke Hewana kunye nezinye izinto kudala kuwatshisa kwi sokukhanyisa eshushu. Oko ke impendulo yombuzo rhoqo kutheni iNyanga angawi.

intshukumo kweLanga

Enye kwakubekwe ezixabisa kukuba ilanga umlomo! Kunye nalo, kunye nenkqubo yethu yonke, nangona uye ucinge ukuba isithuba awuguquguquki, ndisindise, ilawula umhlaba.

Ukuba ukhangela ngakumbi jikelele ngokwesakhelo kweenkqubo namacandelo yonke zeminyele, siyakwazi ukubona ukuba nabo zihamba trajectories zabo. Kulo mzekelo, ilanga with "Hewana" yayo lijikeleza embindini kumnyele iMilky Way. Ukuba ngokwemibandela ukunikela lo mfanekiso phezulu, ikhangeleka ngathi uwele a lot of amasebe, leyo ibizwa ngokuba iingalo esembindini. Kwenye yezi enemikhono, kunye nezigidi nezinye iinkwenkwezi, Langa yethu ihamba, kunye.

eziwayo

Ukanti, ukuba ubuza lo mbuzo, yaye eliphupha? Zeziphi iimeko eziyimfuneko phantsi apho iNyanga wayeza ngozi woMhlaba okanye athathe uhambo oluya kwelanga?

Oku kwenzeka xa umntu yesathelayithi siyeka ejikelezayo ehlabathini into ephambili kunye oma amandla centrifugal, ngokungathi orbit yinto itshintshi aze ongeze isantya, umzekelo, kungquzulwano nge zimpahla.

Kodwa ke inkwenkwezi iza kuhamba, ukuba ekujoliswe ngandlel 'ithile ukuba ayeke intshukumo yayo ijikeleza uMhlaba kwaye anike unikezelo ekuqaleni sokukhanyisa. Kodwa mhlawumbi, ithi nenyanga enyuka kancinci kuphela komzila entsha egobile.

Ukushwankathela: nenyanga ziwe emhlabeni ngenxa yokuba, ukongeza nokutsala umhlaba, kwaye izenzo amandla centrifugal kuyo, ukuba ange mathumbu kube. Ngenxa yezi ziphumo ezimbini ukulinganisa omnye, lo satellite akuthethi kubaleka kwaye ingena kulo mhlaba.
