A gravitational filin

A ra'ayi na "gravitational filin" ya bayyana a cikin kimiyyar lissafi a lokaci daya. Na farko, irin wannan hulda da aka dauke a cikin tsarin na duniya gravitation dokar. Modern lokaci bayyana yawa daga baya. Akwai wani ra'ayi da ƙarni.

Karkashin nauyi nufin da dukiyar da gawawwakin juna ne janyo hankalin, da dukiya da kanta da ake dangantawa da wani taro na jikinsu. Yau a kimiyyar lissafi nauyi ne a matsayin da curvature na sarari-lokaci kusa da m jikinsu.

Jikin haifar a kusa da kansu forcefields. Da tashin hankali na gravitational filin a kowane batu characterizes karfi wanda abubuwa a kan sauran jiki, wanda a cikin wannan musamman batu. Kamar wancan ne gravitational filin g ne rabo na karfi F, mukaddashin a jiki na wani taro m, to jiki taro a gravitational filin.

A filin ƙarfi daidai da shugabanci, girma da kuma aunawa raka'a tare da sani gravitational hanzari, amma a zahirin ma'ana shi daban-daban dabi'u. A filin ƙarfi characterizes jihar sarari a wani batu, da kuma cikin hanzari da kuma karfi bayyana ne kawai a lokacin da jiki ne a wannan lokaci.

Newton a 1687 ya gano cewa biyu suka jawo hankalin da wani karfi tsaye na gwargwado ga square na nesa a abin da suka rabu da juna. Irin wannan ƙarshe da aka yi da shi a kan tushen da kwarewa daga cikin dokokin planetary motsi.

A gravitational filin ne a irin na jiki filin, ta hanyar abin da na Pull jiki (gravitational hulda). Wannan na iya zama wani hulda tsakanin taurari da hasken rana tsarin taurari da kuma tauraron dan adam, Duniya da kuma gawawwakin located kusa da shi.

Duniya ta gravitational filin ne karfi filin, wanda shi ne saboda ta taro janye da centrifugal karfi tasowa a matsayin sakamako na Duniya ta juyawa. Yana dogara ne (ko dan kadan) daga watã nauyi, rana da sauran gawawwakin kazalika da taro na cikin yanayin duniya.

A gravitational filin na duniya shi ne halin da karfi na nauyi, m da wani adadin na daban-daban Kalam. Sashe na daga cikin ginin da ake kira geopotential (shi ne saboda kawai ga janye daga Earth). Domin warware matsaloli daban-daban da shi da aka gabatar a cikin nau'i daga cikin ayyuka na fadada (siffar zobe).

A gravitational filin na Duniya kunshi sassa biyu, wanda ake kira al'ada da kuma mahaukaci. Na farko shi ne asali, shi yayi dace a schematized model na duniya, ne bayyana matsayin ellipsoid na juyin juya halin. Shi ne daidai da real duniya. A anomalous ɓangare na darajar ne kasa, da kuma auna sosai hadaddun hanya. Da zarar matsayin da watã kuma rãnã dangi zuwa Earth ne kullum canja, shi ya faru daga lokaci zuwa lokaci da kuma bambancin da ta gravitational filin. Wannan na taimaka wa tidal deformations na Duniya, ciki har da tides haddasawa.

Bugu da kari, akwai canje-canje a tidal Duniya ta gravitational filin tasowa saboda redistribution na taro a cikin zurfin, da raurawar asa, tectonic ƙungiyoyi, ƙungiyoyi na ruwa da kuma iska talakawa, volcanic eruptions, canje-canje a cikin instantaneous axis na juyawar duniya a kowace rana, kuma ma ta kusurwa gudu. Mutane da yawa girma na irin canje-canje ba za a iya lura, sai suka kiyasta kawai a rubuce.

A gravitational filin na duniya ne dalilin kayyade geoid wanda characterizes gravimetric adadi na Duniya. Bisa ga adadi da aka ba da da tsawo daga cikin surface na duniya. A gravitational filin gama a hydrostatic ma'auni jihar na duniya da kuma bayyana saboda wannan ya karfafa a cikin ciki, bincika da na roba Properties daga cikin Duniya.

A gravitational filin na Duniya taimaka wajen yin lissafin da falakinsu da tauraron dan adam, yanayin na roka motsi. Anomalies na filin taimaka wajen sani da rarraba tafka magudi a yawa a cikin ƙasa ta ɓawon burodi, babba alkyabbarsa, tectonic karba-karba bayar wa, nema ma'adanai.
