Munda yokoka

Lingaliro la "munda yokoka" inatuluka mu sayansi mwakamodzi. Choyamba, mtundu wa mogwirizana ankaona mu chimango cha chilamulo chilengedwe kukoka. Modern akuti anaonekera zambiri mtsogolo. Pali lingaliro kwa zaka zambiri.

Pansi yokoka amatanthauza chuma cha mitembo ndi matanthauzo amakopeka ndi chuma yokha amagwirizana ndi gulu la matupi. Today mu sayansi yokoka amaonedwa monga kupindika kwa danga nthawi pafupi matupi chachikulu.

Thupi kulenga padziko okha forcefields. Mavuto wa kumunda yokoka nthawi imene amadziwika mphamvu amene amachita pa thupi zina, zimene mfundo imeneyi. Choncho yokoka munda ga ndi chiŵerengero cha mphamvu F, kumvera thupi la munthu wina misa m, ku misa thupi m'munda yokoka.

Mphamvu kumunda chikugwirizana ndi malangizo, ukulu ndi kuyeza mayunitsi ndi odziwika yokoka mathamangitsidwe, koma mu kuthupi izo makhalidwe osiyana. Mphamvu kumunda amadziwika danga boma pa mfundo ina, ndipo mathamangitsidwe ndi mphamvu amaoneka kokha pamene thupi pakadali pano.

Newton mu 1687 anapeza kuti matupi awiri kukopa ndi mphamvu mwachindunji njila kwa lalikulu la mtunda pa zomwe anapatukana. Zimenezitu lidalengedwa ndi Iye pa maziko a zinachitikira mfundo za kayendedwe ka mapulaneti.

Munda yokoka ndi mtundu wa kuthengo thupi, amene Chikoka thupi (mogwirizana yokoka). Izi zikhoza kukhala zimachitika pakati pa mapulaneti a dongosolo mapulaneti dzuwa ndi makina, Earth ndi matupi kufupi ndi izo.

munda lapansi yokoka ndi mphamvu munda, umene uli chifukwa kukopa ake misa ndi centrifugal mphamvu akuwuka monga chotsatira cha kuzungulira kwa dziko lapansi. Ndi yozungulira (ngakhale pang'ono) kuchokera mwezi yokoka, dzuwa ndi matupi ena komanso unyinji wa m'mlengalenga.

Munda yokoka ya dziko amakhala ndi mphamvu yokoka, kuthekera ndipo ambiri ofanana nawo osiyana. Part wa nyumbayi amatchedwa geopotential (ndi nkwa kuti kukopa kwa Lapansi). Pofuna kuthetsa mavuto osiyanasiyana izo zikufotokozedwa mu mawonekedwe a ntchito za kuwonjezeka (ozungulira).

Munda yokoka ya Dziko Lapansi imakhala ndi mbali ziwiri, zomwe zimatchedwa zabwinobwino komanso wosasangalala. Woyamba ndi zofunikira, izo limafanana ndi chitsanzo schematized wa dzikoli, akufotokozedwa ngati ellipsoid kusintha. Ndi zogwirizana ndi dziko lenileni. Mbali anomalous wa mtengo wochepa, ndipo anayesa njira zovuta. Pamene malo amene mwezi ndi dzuwa wachibale Earth zikusintha, izo zimachitika nthawi ndi kusuntha munda yokoka. Izi zimathandiza kuti deformations osefukira a Dziko Lapansi, kuphatikizapo mafunde zimayambitsa.

Komanso, pali kusintha m'munda osefukira Dziko Lapansi yokoka akuwuka chifukwa kusokonekera kwa misa mu kuya, zivomezi, kayendedwe tectonic, kayendedwe ka madzi ndi mpweya misa, kuphulitsa mapiri, kusintha kwa olamulira yomweyo wa kasinthasintha wa dziko patsiku, komanso wake mathamangidwe okhota. Ambiri ukulu wa kusintha zimenezi sizingathetsedwe anati, kotero akuganiza theoretically yekha.

Munda yokoka ya dziko lapansi ndicho chiyambi cha kudziŵa geoid amene amadziwika gravimetric chithunzi cha Earth. Malinga ndi chithunzi loperekedwa ndi msinkhu wa padziko lapansili. Munda yokoka kuganiza ndi hydrostatic mgwirizano boma la dziko ndi zingabuke chifukwa cha chimagogomezera m'katikati ake, kufufuza katundu zotanuka a Dziko Lapansi.

Munda yokoka ya Dziko Lapansi zimathandiza kuti kuwerengetsera wa m'mipita a nthambi, njira yodutsamo ya maroketi kuyenda. Anomalies zakutchire kumathandiza kudziwa kufalitsa monyanyira mu kachulukidwe mu matanthwe a pansi padziko, chapamwamba chovala, tectonic magawidwe ndalama, funani mchere.
