Wake wazibuza ukuthi kungani yonke imizimba noma izinto ezisuka phansi zibuyela kwezinye, futhi ngesinye isikhathi, zibuyele emhlabathini lapho ziqale khona? La mandla okukhanga angumkhiqizo we Amandla adonsela phansi amaplanethi, ayilutho ngaphandle kwamandla esiphushwa ngawo siye emnyombweni weplanethi, lapho isikhungo sayo samandla adonsela phansi sikhona.
Yebo ngeke sifinyelele kulelo phuzu ngenxa yezingqimba ezihlukahlukene zomhlaba ezisibekelayo, ngakho-ke singasho ukuthi yonke imizimba esebenzisanayo Ubuso bomhlaba Babuswa amandla ayo adonsela phansi.
Nokho, la mandla adonsela phansi kumaplanethi, endabeni yomhlaba, awanqunyelwe yiwo ungqimba lomkhathi, njengoba isathelayithi yethu yemvelo eyaziwa ngokuthi inyanga igcina ukuzungeza iplanethi yethu ngenxa yamandla adonsela phansi abekwe kuyo. Uma ufuna ukwazi okwengeziwe ngalobu budlelwano be-orbital, ungathintana nolwazi imigudu yamaplanethi.
Ngalo mqondo, singaphetha ngokuthi inyanga nayo inesizinda sayo samandla adonsela phansi, la mandla abonakala ngokuhamba kwamanzi ongqimbeni lwethu lwasemhlabeni, okuya kuwo. esijwayele ukufona izinhlobo zamagagasi okungamandla abangela ukuthi amazinga amanzi olwandle, amachibi nolwandle akhuphuke. Ukuze uthole ukubuka okujulile kwamanzi kanye nobudlelwano bawo namandla adonsela phansi, vakashela amanzi olwandle.
Amandla adonsela phansi ahlobene eduze nesisindo. Ngale ndlela, uma kubhekwa ukuthi uMhlaba unesisindo esingu-9.8 m/s2, umzimba owehla ubheke eplanethini yethu ufinyelela isivinini esingamamitha angu-9.8 ngomzuzwana oyisikwele ekwindla yamahhala.
Kubalulekile futhi gcizelela ukuthi ngiyabonga La mandla adonsela phansi agxilile abangela izindikimba zasezulwini esizaziyo namuhla, njengoba lonke uthuli lomkhathi, izinhlayiya zasemkhathini, nezakhi kwakugxilisiwe ukuze zakhe: amaplanethi, izinkanyezi, namalanga. Uma ufuna ukuqonda ukuthi isistimu yethu yakhiwa kanjani, ungafunda mayelana ukwakheka kwesimiso sonozungezilanga.
Ngakho ukukhombisa ukuthi amaplanethi azungeza iLanga kumane kungenye indlela yokuveza ukuthi amaplanethi azungeza yeLanga Iplanethi, njengomhlaba, ezungeza iLanga ifana neNyanga noma isathelayithi iNASA eyithumela emkhathini, izungeza uMhlaba.
kungani iplanethi izungeza ilanga esikhundleni sokuba ilanga lizungeza iplanethi?
impendulo ilula futhi inengqondo, sase sike sakhuluma ngayo ukubaluleka kwesici yobuningi bemizimba noma izinto.
Ngakho-ke into elula i-orbit ezungeze esindayo, kanti iLanga, ngeso lenyama, liyinto esinda kakhulu eSolar System. Le nkanyezi yelanga inzima ngokuphindwe kayinkulungwane kuneplanethi enkulu kunazo zonke ohlelweni lwethu, kulokhu: I-Jupiter, yona ingaphezu 300 izinkulungwane izikhathi ezinzima kunoMhlaba. Ngalo mqondo ofanayo, singasho ukuthi iNyanga namasathelayithi esiwathulayo azungeza uMhlaba ngoba alula kakhulu kuneplanethi yethu noma anesisindo esiphansi. Funda kabanzi mayelana ne- iziphuphutheki zemvelo.
Amandla adonsela phansi amaplanethi asungula imingcele yawo yamandla phakathi kwawo ngamunye, ngale ndlela futhi, inkanyezi yethu yelanga yasungulwa, ngenxa yamandla ayo adonsela phansi, umzila amaplanethi ayezodonsa ngawo ukunyakaza kwawo kokuhumusha ngisho nokuzungeza.
Uma sibuyela ezicini zomlando zaleli gunya, sithola ukuthi izazi zefilosofi ezifana Kucabanga u-Aristotle ukuthi izinto ezinzima zawela phansi ngokushesha kunezinye. Nokho, ukuhlola kamuva kwabonisa ukuthi lokhu kwakungenjalo ngempela.
Isizathu sokuthi uphaphe liwe kancane kunebhola le-bowling kungenxa yokumelana nomoya., esebenza ku isiqondiso esiphambene njengokusheshisa ngenxa yamandla adonsela phansi. Ngakho, kuhileleke olunye uhlobo lwamandla olugcina luhlakaze inkolelo-mbono eyaphakanyiswa u-Aristotle.
Uma iLanga liheha amaplanethi, kungani lingagcini ngokuwa bese lisha ngaphakathi?
Amandla adonsela phansi ayala ukuzungeza kwamaplanethi
Lona umbuzo omuhle kakhulu ku-logic ebesiyichaza mayelana ne amandla adonsela phansi amaplanethiNokho, ngaphezu kokuwela ngaseLangeni, amaplanethi ahamba eceleni emzileni. Ukuze uthole ulwazi olwengeziwe mayelana nendlela ama-orbits asebenza ngayo, bona.
Ake sithi kuyefana nokuba nesisindo ekugcineni kwentambo. Ngokuyiphendula, uhlala uyidonsa esandleni sakho, njengamandla adonsela phansi wethu inkanyezi yelanga iyaheha amaplanethi ohlelo abheke ngaphakathi kwawo, nokho umnyakazo oseceleni noma umjikelezo wawo ugcina imbulunga izungeza.
Uma bekungekho ukunyakaza okunjalo kwamaplanethi, abezowela enkabeni; futhi ngaphandle kokukhanga ukuya enkabeni, babedubula belandelana umugqa oqondile, okuyiwona kanye okwenzekayo uma udedela intambo, esimweni sokucatshangelwa esikhulume ngakho ngaphambili.
Sonke, ngaphandle kwezimbalwa ezimbalwa, sijwayele ukwenza imisebenzi ehlukene yansuku zonke ngaphandle kokuqaphela amandla adonsela phansi, ngakho-ke, ukuhamba, ukugxuma nokuhamba phezu kolwandle. Umhlaba ngaphandle kokucabanga okuningi embonweni wamandla adonsela phansi ivame kakhulu. Kodwa-ke, lokhu kungamandla ayisisekelo e-physics alawula indawo yonke yethu, kufanele kuqashelwe ukuthi akufani kuzo zonke izindikimba zasezulwini zesimiso sonozungezilanga, ngendlela efanayo ukuthi kuncipha kakhulu ku-vacuum yesikhala kuze kube isikali noma amandla ehlela ku-zero.
Angakanani amandla adonsela phansi amaplanethi akha isimiso sethu sonozungezilanga?
Akuwona wonke amaplanethi anamandla adonsela phansi afanayo
Njengoba sesichazile, kunezici ezihlukahlukene ezithonya amandla adonsela phansi amaplanethi. Ngezansi sizokwethula ezinye zezinkanyezi ezisesimisweni sethu sonozungezilanga kanye namandla adonsela phansi azo. Ukuze uthole imininingwane eyengeziwe mayelana namandla adonsela phansi ku-Mars, ungafinyelela uhlala ku-Mars.
Amandla adonsela phansi eplanethi iMercury
Ngenxa yokuthi i-radius yeplanethi iMercury ingamakhilomitha angu-2440 kuphela, futhi isisindo sayo siphansi kakhulu kuneplanethi yethu enguMhlaba, inesisindo esingaphezulu esingu-3.7 m/s2. Ngamanye amazwi, ukuthi igremu elingu-1 eMhlabeni liyolingana namagremu angu-0,38 eplanethini yokuqala ku-Solar System. Uma ufuna ukwazi okwengeziwe ngale planethi, vakashela ilukuluku mayelana Mercury.
Amandla adonsela phansi eplanethi iVenus
Iplanethi iVenus, lokhu kuthatha indawo yesibili yamaplanethi aseduze kakhulu nelanga, futhi kuyi- njengomhlaba, ngalo mqondo, futhi ngenxa yomkhathi wayo ominyene, inezimo zamandla adonsela phansi ezifana nezaseMhlabeni: isibalo 8.87 m / s2. Uma unentshisekelo ngeplanethi iVenus, ungathola okwengeziwe ku iphrofayela yakho.
Amandla adonsela phansi eplanethi iMars
Naphezu kweqiniso lokuthi i-Mars nayo iyiplanethi efana kakhulu noMhlaba ngezici nezici eziningi, incane, kuminyene kancane futhi kunomoya oshubile kakhulu. Ngalo mqondo, amandla ayo adonsela phansi aphansi kakhulu kunowethu, angu-3.7 m/s2 kuphela.
Amandla adonsela phansi ePlanethi Jupiter
I-Jupiter iyiplanethi yegesi
Lesi ngesinye sezilo ezinkulu nezinkulu kakhulu Zohlelo lwethu Lwelanga. EMpumalanga iplanethi enkulu yegesi Inesisindo esikhulu, kodwa ayinayo indawo eqinile. Kodwa-ke, kumongo ongaphakathi wokucatshangelwa, amandla adonsela phansi alinganiselwa ukuthi makhulu, 24.8 m/s2. Okusho ukuthi, amandla adonsela phansi aphindwe kathathu kuneplanethi enguMhlaba. Ukuze ufunde kabanzi mayelana ne- Iziphuphutheki zeJupiter, finyelela isixhumanisi.
Amandla adonsela phansi ePlanethi iSaturn
Lena ngokungangabazeki iplanethi yesibili ngobukhulu ku-Solar System. ISaturn ewumdondoshiya nayo inkulu kakhulu kodwa ayiminyene kakhulu futhi inegesi, kulokhu amandla adonsela phansi ayo afana kakhulu neplanethi yethu yomhlaba: 10.44 m/s2.
