The rinokweva munda

Pfungwa yokuti 'rinokweva munda "akazviratidza muna wefizikisi pakarepo. Chokutanga, kwakadai nekuita aionekwa mune kuumbwa wesimba rinokwevera zvinhu pasi mutemo. Modern izwi akazviratidza zvikuru paya. Pane pfungwa kwemazana emakore.

Under giravhiti zvinoreva enzvimbo mitumbi vari wezvikamu kukwezvwa, uye pfuma pachayo iri kusonganirana gobvu miviri. Nhasi mune Physics giravhiti anoonekwa somunhu curvature nzvimbo-nguva pedyo wandisa miviri.

Body sika kumativi pachavo forcefields. Makakatanwa pamusoro rinokweva munda chero nguva kuratidza simba iyo anoita panorumwe muviri, izvo ichi kunyanya pfungwa. Nokudaro rinokweva munda? G ndiyo nhamba simba F, kuita pamuviri mumwe guru m, kuti body mass ari rinokweva munda.

Munda simba rinobatana mirayiridzo, nokukura uye kuyera zviyero pamwe anozivikanwa rinokweva kumhanyisa, asi panyama mupfungwa izvozvo zvakasiyana tsika. Munda simba kuratidza hurumende nzvimbo pane imwe nguva, uye kuti kumhanyisa uye simba kungowanikwa kana muviri panguva ino.

Newton muna 1687 yakawana kuti mitumbi maviri zvinokwezva ane simba Proportional kuti mativi ose nechokure zvakaparadzana nenguva iyo kubva mumwe zvakananga. Mhedziso iyoyo yakaitwa kubudikidza naye pahwaro ruzivo mitemo mapuraneti inofamba.

The rinokweva Munda ndiyo mhando mumuviri munda, kuburikidza icho muedzo muviri (rinokweva kudyidzana). Izvi zvinogona kuva nesungano pakati dzomuchadenga zuva nenyika dzinotenderera pariri mapuraneti uye satellites, Earth uye miviri iri pedyo nayo.

rinokweva munda Earth iri munda simba, iyo imhaka ayo vakawanda kukwezvana uye Centrifugal simba yomuka sezvo migumisiro Kutenderera paNyika. Hazvina zvaanoda (kunyange zvishoma) kubva mwedzi giravhiti, zuva uye zvimwe miviri uyewo vakawanda pasi muchadenga.

The rinokweva munda nyika kunoratidzwa simba regiravhiti, kwaniso uye zvinoverengeka nomukaka siyana. Part of chivakwa rinonzi geopotential (akafanirwa chete kuti kukwezvana Pasi). Kuti zvinetso zvakasiyana-siyana ngachipiwe muchimiro mashandiro ari kuwedzera (idenderedzwa).

The rinokweva munda Nyika ine zvikamu zviviri, izvo hunonzi uye mwero. Wokutanga kunokosha, yakafanana schematized muenzaniso yepasi, inoratidzwa ive ellipsoid chimurenga. Hazvina kunoenderana chairo nyika. The anomalous Chikamu mutengo kushoma, uye akayera zvikuru kunzwisisa nzira. Kamwe nzvimbo mwedzi uye zuva hama kuna Earth ari dzichichinja, zvinoitika nguva nenguva uye kusiyana rawo rinokweva munda. Izvi zvinobatsira kuti naTidhari deformations the Earth, kusanganisira Maze zvinokonzera.

Uyezve, pane kuchinja rinokweva munda naTidhari Dzenyika anomuka nokuda redistribution nevazhinji makadzika, kudengenyeka kwenyika, tectonic kufamba, mapato emvura uye mhepo makore, kuputika kwemakomo, kuchinja nguva imwe akabatana kuti kutenderera kwenyika pazuva, uye zvaro chisina kutsetseka velocity. Vazhinji kwakakura kuchinja kwakadaro hazvigoni kuchengetwa, saka zvinofungidzirwa chete hunonzi.

The rinokweva munda enyika ndiyo hwaro Pakusarudza geoid iyo chinoratidzwa gravimetric mufananidzo Nyika. Maererano nomufananidzo yakapiwa kukwirira pechiso nyika. The rinokweva munda kupedza hydrostatic zvakanyatsoenzana mamiriro yepasi musimuke nokuda ichi zvinosimbisa kwaro mukati, mundotarisisa kwakavharwa nenyama ehupfumi the Earth.

The rinokweva munda Nyika kunobatsira kuti Masvomhu ari kutenderera satellites, trajectory pakati zvitundumuseremusere kufamba. Anomalies dzesango kunobatsira kuziva kuparadzira hadzina kufambiswa zvakanaka zviri arambe achirema panyika nechepasi, rokumusoro jasi, tectonic zoning mari, tsvaka zvicherwa.
