Ngaphambi kokuthi ngikutshele kahle mayelana ne 0 amandla adonsela phansi emhlabeni, kubalulekile ukunikeza amazwibela okuthi konke kwenzeka kanjani. I-apula labangela ukuba u-Isaac Newton abone ukuthi ijubane lomzimba oshaya phansi kanye nomdanso oshelelayo wezinkanyezi ezisemkhathini kwakuhlobene namandla afanayo. Uma ufuna ukujula, ungabonisana ukubaluleka kwamandla adonsela phansi.
Ngalo mqondo, yonke imizimba yomkhathi ithatheka ngendlela engenakubuyiseka futhi, naphezu kweqiniso lokuthi kubukeka sengathi isiqalo senoveli yothando, amandla adonsela phansi ayingxenye yomlando wendawo yonke, umbusi wayo yonke imisinga yawo, naphezu kokubonakaliswa njenge i-force brittle (cabanga nje ngamandla obudlelwano be- Umhlaba kanye nenqwaba esabekayo onayo). Ukuze ufunde kabanzi mayelana namandla adonsela phansi, ungavakashela.
Ngokunjalo, ukuze kuqhutshekwe namandla adonsela phansi u-O emhlabeni, omunye usosayensi, uSir Isaac, waba ngowokuqala ukucacisa inkolelo-mbono eyadalula ngefomula elula indlela yemizimba endaweni. indawo yonke: imizimba emibili ithakathwa ngokulinganayo umkhiqizo wobuningi bayo futhi ngendlela ephikisanayo futhi ngendlela efanayo ilingana nesikwele sohambo phakathi kwayo. Uma ufuna ukwazi okwengeziwe ngokuthi lo mbono uhlobana kanjani nezinye izindikimba zasezulwini, sincoma ukuthi ufunde mayelana amandla adonsela phansi amaplanethi.
Kodwa-ke, kunomehluko omncane phakathi kwaleyo yezigxobo kanye neyase-Ecuador, amandla adonsela phansi kungamandla okungenakwenzeka ukubaleka. Ayikho into ebizwa ngokuthi i-zero gravity, ngisho nasemkhathini. Kwenzekani kosomkhathi eziteshini zasemkhathini, ezipakwe amamitha angamakhulu ambalwa ukusuka (i-International Space Station ingamakhilomitha angama-400 ukuya phezulu), ukuthi basekwindla mahhala.
“Izinto eziphilayo ezimbili ziyagadla endaweni efanayo yamandla adonsela phansi. Nokho, awukho umehluko emandleni phakathi kwabo,” kuchaza uFernando Pina, isazi sezibalo enkampanini yaseSpain iDeimos Space. Kungakhathaliseki ukuthi sizama kangakanani, ngaphakathi emkhathini mancane amathuba okuba sigweme ukuthakathwa nguMhlaba. Zimbili kuphela izindlela lapho isimo samandla adonsela phansi esisuswayo singalingiswa; ngokuwa kusuka emibhoshongweni eqondile, lapho umbono wokukhanya ungamasekhondi ambalwa noma nge izindiza ezicatshangelwayo.
Isikhathi siphindaphindekile lapho uzama ukubonisa amandla adonsela phansi angu-0 emhlabeni
Indiza iphakama lapho indiza inamandla angaba ngu-47 degrees. Njengoba ikhuphuka ifinyelela ubude obuphakathi kwamamitha angu-4.000 8.000 nezi-XNUMX XNUMX, ingaphakathi lendiza limelana namandla adonsela phansi ajatshuliswa ukukhangwa komhlaba nokungabi nazinzwa. I-inertia, evezwa ngokuzenzakalelayo, isenzakalo esenza sinamathele esihlalweni semoto lapho inamathela ukusheshisa. Idalwa ukwanda njalo kwejubane, okuphoqa indiza ukuthi iqale phezulu futhi ikhuphuke isuke eMhlabeni. Uma ungajahi ngaphezu kwe-G-force noma ukuphuthuma okuqinile kwento ephilayo, okuthi esimweni somhlaba ingu-9,81 m/s2, awukwazi ukukhuphuka.
Uma ukuphakama okuphezulu sekufinyelelwe, izinjini zendiza zicishe zimiswe ngokuphelele (okungenani okuncane kushiywe ukuze kuvinjwe ukuqina komoya ekuwohlokeni), ngale ndlela indiza izosebenza njengendawo yokukhosela ngaphakathi, ibhekane nokuqina kwayo umoya. Kuleli qophelo, wenza ukwehla ngokungenakugwenywa, futhi njalo ngendlela ehloliwe, njengoba umshayeli usezinikezele kakade ukuthi aqondise ikhala emkhathizwe (ukuzivocavoca okuphikelela cishe imizuzwana engu-20), ngenxa yokuthi amandla akhangayo. umhlaba awubaleki ngokuphazima kweso, kubangwa ukukhanya.
Kokubili indiza nomoya wayo wangaphakathi kuyazulazula futhi kudilike ngesikhathi esifanayo, kube namandla okukhanga ngokulinganayo, kodwa phakathi kokukodwa nokunye amandla anjalo. i-microscopic lawo mandla adonsela phansi ashabalala cishe ngokuphelele. Kunjengokungathi umzimba ongaphakathi kokuhambisana udilike esikhaleni, ngoba kulelo phuzu amandla okuhlangana endiza enkulu aya kancane kancane.
Ngalezo zikhathi zokuwa kwamahhala, cishe ama-20 isikhathi ngasinye usebenzisa noma ubani ondiza naye, uyaqaphela i-microgravity noma cishe ukususwa okuphelele kwamandla adonsela phansi. Indiza eye yaba namandla afinyelela ku-20 degrees (ayehli ikhala libheke phansi), iphinde ikhanyise izinjini zayo ezintathu ukuze ikhuphuke umqansa ingaphahlazeki. Amaphromoshini noma ukuncishiswa kwe-Korean kulingisa isimo esifanayo, ukufinyelela amaminithi ambalwa wokukhanya phakathi nezindiza.
Ngesikhathi sokwehla okuhloliwe, amandla ezinjini angancishiswa, okungukuthi, indiza ingathuliswa ukuze ubunzima obukhona bungasondeli ku-zero, kodwa buseduze namandla adonsela phansi eNyanga (1/6 ye-Gravity Earth) noma i-Mars (1/3 ye-gravity yoMhlaba). umhlaba). Ukuze uqonde kangcono uhambo lwasemkhathini, bheka ukuhamba emkhathini komuntu.
Imephu yomhlaba yamandla adonsela phansi
Ngomunye umqondo, enye indlela yokuhlobanisa amandla adonsela phansi 0 emhlabeni iwukusebenzisa ibalazwe lawo, okungukuthi, ukushesha kwamandla adonsela phansi kuba nomehluko omncane kule planethi. Ukumelwa kwe-ellipsoidal kwe umhlaba kanye nokungafani isisindo endizeni yayo kubangela ukushwiba phakathi kuka-9,78 m/s2 enkabazwe kanye no-9,83 m/s2 ezigxotsheni. Ukuze uthole ukuhlaziya okujulile, ungavakashela.
Lezi zitholakala eduze nendawo yeplanethi. Ngesikhathi esifanayo, amaketanga angalingani awanaso isisindo esifanayo ezindaweni eziphakeme kakhulu njengasezindaweni eziphansi kakhulu, futhi izilwandle azinakho ukuvumelana okufanayo. Yena imephu yomhlaba yamandla adonsela phansi, esanda kwembulwa eNorway, ilandelwe kusetshenziswa idatha yenkanyezi yase-Europe u-Goce. Futhi, ukubona ukuthi amandla adonsela phansi azithonya kanjani izici zamaplanethi kungase kuthakazelise, ngakho-ke zizwe ukhululekile ukukubheka.
Lezi zinguquko kumandla adonsela phansi zingasiza ukubona ukugeleza kwe-lava ngaphansi kwezintaba-mlilo, zisungule uhlelo lokuphakama kwamaketanga enani angazelelwe e-cosmopolitan, zingadalula ukuthi ukulahlekelwa amashidi eqhwa amakhulu kangakanani, noma ziqalise indlela yokuziphatha kwezilwandle ngaphandle kwamagagasi, imimoya, nalo lonke uhlobo lwamaqhwa. amagagasi. Kubekwe phezulu kukho kokubili idatha, isikali sezinye iziphathimandla singabongwa.
Ungakwazi yini ukuthola "0 amandla adonsela phansi" Emhlabeni?
Njengoba siza cishe ekupheleni kwalesi sihloko manje sesibeka umbuzo omkhulu: Singakwazi yini ukuyithola 0 amandla adonsela phansi emhlabeni? Ngakho-ke, kulokhu, ngingasho, ngokobufakazi obunikezwa ochwepheshe ngale ndaba, ukuthi isisindo, amandla iplanethi eheha ngayo imoto yasemkhathini, ilingana ngokulinganayo nesikwele sendlela, ngakho-ke, iyancipha ngokushesha. lapho umshini usuka kude nawo.
Okusho ukuthi, ngokuphinda kabili indlela eya enkabeni yayo, ukuhlobana kungaphansi ngokuphindwe kane (izikhathi ezingama-22); ngokuyigoqa kathathu, isifaniso sincane izikhathi eziyisi-9 (izikhathi ezingama-32), phakathi kokunye. Nokho, akusona isizathu sokuthi kungani amatilosi emkhathini futhi izinto zisesimweni sokukhanya. Ukuze uthole ulwazi olwengeziwe mayelana nendiza yokuqala yasemkhathini ephethwe umuntu, vakashela indiza yokuqala yasemkhathini.
Osomkhathi bawuzwa umphumela wokukhanya ngoba basekuweni okungaguquki kwamahhala eduze neplanethi, bajikijelwa emkhathini ngomsinga kanye nesivinini esimisiwe ukuze bahlale emkhathini. i-orbit. Ukuze uqonde kangcono amandla adonsela phansi emkhathini, ungafunda futhi mayelana iziphuphutheki zokwenziwa.
Unika uhlelo isivinini esikhulu futhi ama-navigator emkhathini azosakazeka emkhathini, imikhonto inamandla amancane futhi izogcina iwele umhlabathi. Kwenzeka okufanayo kumgibeli wekhebula uma ikhebula belingaphuka futhi uma igumbi lingathinti umoya noma amalensi, kubonakala ukukhanya. Ngakho-ke akukho okunye ongakusho mayelana ne-zero gravity Emhlabeni, kuyathakazelisa akunjalo?
