indlela enqumayo amandla adonsela phansi awuthinta kanjani umhlaba Kungenzeka ngesisindo sethu. Ngalo mqondo, lokho isikali esisibonisa kona akuxhomekile nje kuphela ngobuningi bethu, kodwa futhi namandla omkhakha wokudonsela phansi esikuwo. Lokhu kumelela ukuthi, ngesidalwa esifanayo, singakala kakhulu noma ngaphansi kuya ngokuthi sisemhlabeni, eNyangeni noma emkhathini.
Amandla adonsela phansi awuthinta kanjani umhlaba?
Isisindo samanje singabangelwa ukuba ndikindiki kokulala, okuwukhulisa ngokusobala, kodwa ukwahlulela kwawo okuphumelelayo kuyiqiniso esifundiswa ukukunqanda: Umhlaba sidonse. Ngokuqinile, ngokucijile nangokungenathemba. Kwanele ukuthi sibheke indawo esihlala kuyo, ngokubusa kwendawo esizithola kuyo, ukuze sihlangabezane nezibonelo zokumelwa kwayo kanye nesibindi, esivame ukuvela emvelo, esikwenzayo ukuze sinxephezele.
Ukuhlola uma umfutho wokusheshisa wawusuka ku-a masa wento, waphotha amabhola enganononi ahlukene ngendiza etshekile futhi wabonisa ukuthi ijubane lalifana kuzo zonke izindaba. Inkinga kaGalileo ekufinyeleleni umphumela onokwethenjelwa ngokuphelele kwakuwukungqubuzana okwakunikezwa umzila ohambayo ayewusebenzisa njengendiza etshekile. Ngo-1581 wazama ukuyixazulula ngokujikijela amabhola amabili ahlukene ukusuka phezulu kombhoshongo wedolobha lakubo, iPisa, kodwa kulokhu, ukungqubuzana bekuzolingana nomkhathi wasemhlabeni.
Ngeshwa, uGalileo akakwazanga ukuba ngomunye wezinkulungwane zezithameli ezibuke ukuvezwa kwe-hypothesis yakhe, evela kububanzi obufanele: indawo ngaphandle umoya we Luna. Usomkhathi uDavid R. Scott wema ngaphambi kwegumbi lephethini yenyanga ephethe ipeni lekhoni esandleni esisodwa nesando sesazi sokuma komhlaba kwesinye. Wazikhulula zombili izingqikithi ngesikhathi esisodwa futhi wabonisa emhlabeni ukuthi bobabili bafinyelela emhlabathini wenyanga ndawonye.
Amandla amandla adonsela phansi emhlabeni
Enye indlela yokubona indlela amandla adonsela phansi athonya ngayo umhlaba ngokusebenzisa izibilini ezinamadwala eziya olwandle. Kuyamangaza ukukhanga okuqinile, okufanayo emakhulwini eminyaka edlule, kodwa lokho kusaphonsa okungaziwa emphakathini oqinisekisiwe. Uma singabandakanyi noma sikhulisa inqwaba endaweni engaguquki, kushintsha isimo amandla adonsela phansi. Yazi kahle ukuthi iyinkimbinkimbi kangakanani, ngoba izakhi ezimbalwa ziyangenelela ku-anomalous yamandla adonsela phansi.
Ubuningi bezinto eziphilayo buyisici esibalulekile. ETrieste, e-Italy, iqembu labafundi liphenya indida u-Isaac Newton ayichaza emakhulwini amathathu eminyaka adlule. Uphawu luyazamazama. Kulesi sifunda kukhona i-grotto enkulu, ecaphuna i-Giant Grotto. Ibanga lesisindo emhlabathini ongaphansi wehlisa amandla adonsela phansi esifundeni.
Ngamanye amazwi, uma sibeka imoto enesisindo somthamo owodwa, lapha izolayisha amagremu amahlanu ngaphansi. Kodwa i-grotto akuyona ukuphela kwento ehilelekile”, kuchaza uCarla Breitenburg, eNyuvesi yaseTrieste. Umfundi wambuza ukuthi kungani kunezimvume zamandla adonsela phansi uma bengazange bayiguqule indawo ekubaleni kwabo. Impendulo iwukuthi umsebenzi we Inyanga neLanga zithatha indawo yendima yamandla adonsela phansi. Ukumelwa koMhlaba kuyanwebeka futhi kushwabene nomsinga oqhubekayo wolwandle nolwandle.
Okuwukuphela kwesizathu sokuba ne-clairvoyance ephelele kulokhu kuphazamiseka sisuka endaweni. Kwakungenxa yalokhu kuqonda ukuthi i-European Space Agency idale umsebenzi we-GOCE. Ucwaningo oluzuzwe yilokhu satellite ungathola ama-compendium abalulekile, njengokumelwa kwensimbi ngaphansi komhlaba.
Kulolu hlelo lwemibono, idatha eqoqwe yisathelayithi, evela esikhungweni socwaningo se-European Space Agency e-Rome, inikela ucwaningo olwengeziwe emphakathini wesayensi. Ilungu leqembu lithi ukuze kuzuzwe ukunemba okukhulu kwe indawo yethu ye-gravitation iplanethi, isathelayithi indizela phansi kunangaphambili: iseduze ngangokunokwenzeka endaweni engaphandle yomoya, nokho kulowo mjikelezo womoya kunzima. I-GOCE ihlale igcinwe endaweni ephakeme ephansi kunamasathelayithi okuvunyelwene ngawo.
Manje izowela amakhilomitha angama-268 iye ku-237. Inhloso ebalulekile ukuthuthukisa isampula ye-geoid, ukumelwa ngokomzimba amandla adonsela phansi emhlabeni. Okunye ukuxosha i inkambo eqhubekayo yokushintsha komkhathi, ingena kulokho okwenzeka ngaphansi koqweqwe lomhlaba wethu.
Amasathelayithi asuka kwabanye abaphathi abahlobene namandla adonsela phansi okuthiwa i-GRACE ahlangabezana nokuvumelana kweqhwa e-Greenland. Idatha iqoqwa e-Potsdam, eJalimane. Mayelana nalokhu okungenhla, ososayensi bakhomba lokho kulinganisa ye-geoid inquma ngendlela efanayo kumakhonsathi njengokucushwa nokuba ngomkhumbi.
Imithetho yesisindo mayelana nendlela amandla adonsela phansi athonya ngayo umhlaba
Isihlakaniphi sokuqala, okwathi ngekhulu leshumi nesikhombisa, sanikeza ukuqina kwezibalo encazelweni yamandla adonsela phansi kwakungu-Isaac Newton. yodumo lwakhe Umthetho We-Gravitation I-Universal nemithetho yayo yamanje kuyaziwa ukuthi izinto ezimbili ziloya zodwa ngamandla afanayo, kodwa ngezindlela ezihlukile futhi ngokushesha zilingana ngendlela elinganayo nephelele yendlela ezihlukanisayo, okusho ukuthi, nakuba kubonakala kungavamile. , siloya ngokwethembeka Umhlaba njengoba esiloya.
Futhi, imfihlo yokuthi yithi njalo esiwisa phansi, hhayi okuphambene nalokho, isesixukwini: uma into enayo isamba esikhulu, amandla amakhulu adonsela phansi ewaveza kwenye. Inkolelo-mbono kaNewton yavumela ukudalula inani elikhulu lokungajwayelekile kwemvelo obekuyimfihlo kuze kube manje, njengokugeleza kwezinkanyezi, amagagasi, okubangelwa amaza. isenzo samandla adonsela phansi enyangeni, noma imithetho elawula ukuwa kwezinto eziphilayo, futhi yaqhubeka ibusa kwaze kwafika uhlobo olusha lwesayensi oluzohlasela lesi samanje esimangalisayo.
Usuku nosuku ethonyeni lamandla adonsela phansi emhlabeni
Kunoma yikuphi, uma i- amandla adonsela phansi akuzange kuqinise ukuphila kwethu ndawonye esabelweni sakhe esimbaxa-mbili njengomthombo wokuphila womgcini wejele, indawo yonke yayiyoba ihlane lasemhlabeni, elifanekisela iplanethi yethu enamatshe, futhi elingenakukwazi ukulondoloza umkhathi owanele kuwo ngokwawo, njengoba laliyogwadule liye emkhathini. Esikhundleni salokho, sijabulela inkanyezi lapho amanzi angagcinwa khona esesimweni esiwuketshezi, ehliswe ngendlela emelela imvula futhi afinyelele ezindaweni ezicashe kakhulu lapho ukuphila kudinga khona ukuze kuthuthuke.
Zonke izidalwa eziphilayo ziye zaguqulwa ngokuhambisana nemithetho yayo: izitshalo ziphonsa izimpande zazo ngaphansi komhlaba ukuze zifune ukudla kanye nezilwane futhi abantu baye bavumelana nezinqubo zabo zegazi, ukugaya, imisipha kanye namathambo emsebenzini wokuvinjelwa noma izinzuzo ezinikelwe yilo mthetho. . Izinkanyezi zibuthana zizungezane ezinhlelweni yezindlela ezizungezayo ngenxa yohlaka lwamandla afinyelela ku-agros yawo edonsela phansi.
Indaba emkhathini iyathakazelisa, iqongelela futhi ikhiphe amasu afana nodwendwe lwezinkanyezi, ukwethulwa kwezinkanyezi noma ukuphazamiseka kwabantu ababi. izimbobo ezimnyama.
Ngale ndlela, indlela amandla adonsela phansi athonya ngayo umhlaba, asibamba ngokungenathemba endaweni yonke, kodwa, ngokufanelekile, izidalwa ezinjengezinyoni ziye zahluma kuwo, eziye zasifundisa ukuveza ama-hang glider, ama-paraglider noma ama-paraglider ukuze zizijabulise ngenjabulo enkulu kakhulu. ukuyitshala .
