Izikhathi eziningi, thina bantu sijwayele ukuhamba, ukugxuma kanye nokuhamba emhlabeni ngaphandle kokucabanga ngezimo ezinjalo, njengakumbono we-gravity. Kodwa-ke, lokhu kungamandla abalulekile e-physics, futhi akufani kunoma iyiphi iplanethi, ngendlela efanayo ukuthi kuncipha kakhulu ku-cosmic vacuum kuze kufike ku-0. Yingakho noma yikuphi i-cosmos, i-cosmos ukubaluleka kwamandla adonsela phansi kumaplanethi zihluke ngokuphelele.
Ngalo mqondo, amandla adonsela phansi ancike kubuningi. Yingakho, uma kubhekwa ukuthi uMhlaba une-gravity engu-9.8 m/s2, into ewela ngaseplanethi yethu inesivinini esingamamitha angu-9.8 ngomzuzwana ekwindla yamahhala. Manje, ingaba yini idijithi kwamanye amazwe, izinkanyezi noma imithala? Hhayi-ke, kulesi sihloko ngizokhuluma nawe ngqo ngalokhu, I-Value of gravity kumaplanethi.
Inani lamandla adonsela phansi kumaplanethi
Mayelana nalokhu okungenhla, iValue of gravity in the amaplanethi, yilezi ezilandelayo:
amandla adonsela phansi ku-mercury
Kusukela engaba K Es Es Escha! Escha Escha! Escha Escha! Escha! ingamakhilomitha angama-2440 kuphela, futhi isisindo sawo sincane kakhulu kunomhlaba, ine-gravity yangaphandle engu-3.7 m/s2. Ngamanye amazwi, 1 igremu ku Umhlaba ubiza amagremu angu-0,38 enkanyezini yokuqala yeSolar System.
Amandla adonsela phansi kuVenus
Venus Yiplanethi ethatha indawo yesibili ye- Uhlelo lomkhathi futhi efana kakhulu noMhlaba ngobukhulu nomoya owugqinsi. Kusobala ukuthi amandla adonsela phansi azofana kakhulu nawethu, isibalo singu-8.87 m/s2.
amandla adonsela phansi enyangeni
Ngakolunye uhlangothi, ukubaluleka kwamandla adonsela phansi kumaplanethi kubalulekile, kodwa kubalulekile ukuchaza indlela amandla adonsela phansi ayiyo emhlabeni. luna. Yingakho kubhekwa ukuthi amandla adonsela phansi lokhu angaphansi ngokuphindwe izikhathi ezingu-6 kunoMhlaba, okungukuthi, uma sinyathela phezu kwenyanga besingeke simashe ngendlela efanayo neplanethi yethu ngenxa yalolo shintsho oluyisisekelo olwenzeka. nxazonke kwe amandla adonsela phansi.
Ngokufanayo, sasihamba ngokugxuma, njengoba umzimba wethu uzizwa ulula kakhulu. Ukwenza isibonelo, umuntu emhlabeni enesisindo esingama-60 kg, ku- Luna ingaba nesisindo esingu-10kg. Kungakho osomkhathi ababeke unyawo eNyangeni basebenzisa amasudi athile, ukuze imizimba yabo ingacashile futhi intante, kanye nayo yonke imiphumela yokuthi uguquko olunodlame olunjalo endaweni ezungezile olulwamukelayo lumelana nayo ephilayo.
Inyanga Gravity Imiphumela
Amandla adonsela phansi eNyanga aheha amanzi olwandle nezilwandle, okujabulisa amagagasi okukhulunywe ngawo ngenhla. Ukuze sicabange kancane, amagagasi ayizinyuso kanye nokwehla kwezinga lolwandle okuvela izikhathi eziningana ngosuku. Ngakho-ke, iNyanga idala amagagasi amabili: i-high tide noma i-high tide, okuwumzuzwana lapho amanzi efinyelela ukuphakama kwawo okuphezulu; kanye ne amanzi aphansi noma amanzi aphansi, okuyinkathi lapho amanzi efinyelela ubude bawo obuncane.
amandla adonsela phansi ku-Mars
El iplanethi iMars kuhlanganisa izinhlobo eziningi ze-Earth. Lawa maplanethi womabili anenani elilinganayo lendawo yezwe, anezingqimba ze-polar, futhi womabili ajabulela igagasi elilinganayo kuma-spin axs awo, ngalinye lidala ukuguquguquka okuqinile kwesizini. Ngesikhathi esifanayo, womabili amaplanethi abonisa isiqiniseko esiqinile sokuthi aye abhekana nezinguquko zomoya ezikhathini zasendulo.
Ngesikhathi esifanayo, amaplanethi amabili awalingani kakhulu, futhi anenani elibalulekile lobuso. Isibonelo, ukucindezela komkhathi ku-Mars kuyingxenye eyodwa kuphela yaleyo eMhlabeni, okuphakathi kwama-millibar angu-7,5 ku-Mars. Mars, nasemhlabeni ngaphezudlwana kuka-1000. Izinga lokushisa eliphakathi nendawo liphansi futhi ku-Mars, lihlezi endaweni ebandayo engu-63°C, ngokulingana no-14°C eMhlabeni. Futhi nakuba ukuphikelela kosuku lukaMartian kucishe kufane, ukuphikelela konyaka kaMartian kunwetshwa ngokucacile, okuyizinsuku ezingaba ngu-687.
Kodwa umehluko omkhulu phakathi kwamaplanethi amabili ukuthi endaweni ye-Mars amandla adonsela phansi abuthakathaka kakhulu kunaseMhlabeni, ngaphansi kwama-62% ukuba abe ncamashi. Umuntu onesisindo esingamakhilogremu ayi-100 eMhlabeni angakala 38 kg kuphela ku-Mars.
Lo mehluko kumandla adonsela phansi angaphezulu kungenxa yezinto eziningi ezingalingani njengobunzima, ukuminyana, kanye ne-radius yeplanethi. Nakuba i-Mars inendawo ecishe ilingane noMhlaba, iyingxenye kuphela yobubanzi beplanethi yethu futhi ayiguquguquki kangako. Okungukuthi, I-Mars inomzimba ongaba ngu-15% woMhlaba kanye ne-11% yesisindo sayo.
Ososayensi baye bacabanga ukuthi amandla adonsela phansi e-Mars asekelwe ku-gravity hypothesis kaNewton, ethi amandla adonsela phansi akhishwa into alingana nesisindo sayo. Uma umzimba oyindilinga njengeplanethi enesisindo esinikeziwe (kulokhu, i-Mars) kusetshenziswa, amandla adonsela phansi angaphezulu azocishe alingane nesikwele sobubanzi bayo. Uma kusetshenziswa umzimba oyindilinga onokuminyana okumaphakathi esinikeziwe, uzoba ngaphezulu noma ngaphansi ngokwendawo yayo.
I-Mars inesisindo esingu-6,4185 x 10^23 kg, okungama-0,107 obunzima boMhlaba. Ngendlela efanayo, ithola indawo engaba ngu-3.390 km, enenani elingama-0,532 ama-terrestrial radii. Ngakho-ke, amandla adonsela phansi ebusweni Mars kungashiwo ngokuqondile ngokuthi: 0.107 / 0.532^2, lapho sithola khona inani le-0,38. Okusho ukuthi, izoba nesivinini esingamamitha angu-3,724 ngomzuzwana.
Ukungena kwe-Mars amandla adonsela phansi kanye nomthelela wawo ku- izidalwa zasemhlabeni kuyisinyathelo sokuqala esibalulekile uma sifuna ukuthumela osomkhathi, ochwepheshe, ngisho namakholoni ngolunye usuku. Okubi kakhulu, imiphumela yokuboniswa kwesikhathi eside kula mandla adonsela phansi, okuba ngaphezudlwana kwengxenye yesithathu Yomhlaba, kuzoba isici esibalulekile sanoma yimuphi umsebenzi ozayo ohlosiwe ozayo noma imicimbi yekoloni.
amandla adonsela phansi ku-jupiter
Manje, kuleli qophelo sifika ezilo ezinkulu zeSolar System. Siqala ngaye ijupiter esesabekayo. Leli zwe elikhulu legesi linesisindo esikhulu, kodwa hhayi indawo eqinile. Kodwa-ke, kumongo wangaphakathi wokucatshangelwa, amandla adonsela phansi angesabekayo kokuthi 24.8 m/s2. Ngamanye amazwi, cishe kathathu lokho emhlabeni.
amandla adonsela phansi ku-saturn
Manje sihambela iplanethi yesibili ngobukhulu eSolar System, Saturn. Inamandla kakhulu kodwa ayiminyene kakhulu, futhi futhi gaseous, amandla adonsela phansi acishe afane neyethu, angu-10.44 m/s2.
Amandla adonsela phansi e-Uranus
Manje Inani lamandla adonsela phansi kumaplanethi, ikakhulukazi ku I-Uranus njengoba lesi sikhulu segesi sinokuminyana okuphansi, ngakho-ke ngendlela efanayo sinesisindo esifana nse nesoMhlaba. Umhlaba, ungu-8.7 m/s2, iphansi kakhulu kuneyethu naphezu kobukhulu bayo izikhathi ezi-4 ezinkulu kunomhlaba wethu.
amandla adonsela phansi ku-neptune
Ekugcineni, iplanethi yokugcina nehlukene kakhulu yesimiso sonozungezilanga Neptune, igumbi elikhulu kunawo wonke. Ubukhulu ngokuphindwe izikhathi ezingu-17 kunoMhlaba, futhi mncane kakhulu, ngakho amandla adonsela phansi ama-11.15 m/s2 kuphela, athi ukuphakama kunalapha.
Ngakho-ke ngithemba ukuthi kube usizo kakhulu kuwe ukwazi ukubaluleka kwamandla adonsela phansi amaplanethi.
