Mamiriro epasi (gravitational field) chimwe chezvinhu zvinooneka zviri pamusoro pePasi. Nekuda kwekukura kukuru kwePasi, simba rinokwevera zvinhu pasi rakanyanya uye rakakwana sekudaro. Zvekuti, nekungoita kusvetuka kuri nyore, zvinobva zvangokwezva zvakananga pasi pasina kutambisa nguva. Hapana mubvunzo kuti simba regiravhiti rine simba.
Gravity chinhu chakavanzika chinoramba chiri chidzidzo chenguva dzose chedzidziso uye kudzidza kwakazara. Migumisiro yaro pachisiko chose, ndeavo vanotonga mafambiro nekudyidzana pakati penyeredzi. Hapana mubvunzo kuti yakakosha kupfuura zvinoita, saka kudzidza nezvesimba rinokwevera reNyika kunobatsira kuburitsa chokwadi. Inongova muromo wechando.
Iwe unogona zvakare kufarira chinyorwa chedu: Ndeapi Mafambiro mashanu ePasi uye Migumisiro Yawo?
Chii chinonzi simba regiravhiti? Pfupiso yezvese zvinomiririrwa neganda iri!
Sezvinozivikanwa, zvinhu zvose zviri muchadenga zvinodzorwa nenheyo nemitemo yakafanana izvo zvinosimudzira kunzwisisa kwavo. Chimwe chezvinonyanya kukosha mutemo wesimba rinokwevera pasi rose, uko ukama hwemafambiro ari muchadenga hunofumurwa.

Hapana mubvunzo kuti simba rinokwevera zvinhu pasi ndicho chinhu chisingaoneki seri kweketeni rinodhonza tambo dzemuchadenga. Nekuda kwaizvozvo, zvinokwanisika kunyatso tsanangura kuti zvakasiyana sei zvinhu zvekudenga zvine hukuru hwakabatana zvinopindirana.
Mupfungwa iyoyo, munda wegiravhiti ndiro shoko rinoshandiswa kuratidza masimba anomirirwa negiravhiti. Nzvimbo yega ine nhevedzano yehunhu hwepakutanga hunosiyana kana chinhu chine huremu chaiswa.
Nemamwe manzwi, kana huremu "x" hwakaiswa munzvimbo yenzvimbo "x", iyo nzvimbo yakatenderedza huwandu inoshanduka. Chaizvoizvo, iwe unozowana akasiyana maficha nekutsiva kana kufukidzira izvo zvawaive nazvo iwe usipo pamberi pemuviri une misa. Kubva panguva iyoyo zvichienda mberi, iyi muganhu wezviitiko unozozivikanwa senzvimbo yegiravhiti.
Izvi zvinosimbiswa kana yechipiri misa, inonzi control mass, inoratidzwa kune yekutanga misa yekuedza. Kuve zvinhu zviviri zvine masasi akasiyana akaiswa munzvimbo yenzvimbo, kusangana kwavo kunotanga. Nenzira iyo, ivo vanokwezva mumwe nemumwe zvichienderana nekuti ndiani ane yakanyanya density yenguva iyoyo.
Simba rekukwezva pakati pezviro zviviri zvichange zvichinyatsoenderana nehuwandu hwehuwandu hwavanowana. Naizvozvo, kusimba kuchasiyana nzira maererano nechinhu ichi sekudaro.
The gravitational field uye maitiro ayo. Equation inorerutsa imwe yekudyidzana kwakakosha!
Kuburikidza negiravitational field uye maitiro ayo, zvave zvichibvira kujekesa kudyidzana pakati pezvinhu zviviri zvikuru. Hukuru hairevi chimiro chemasangano makuru, asi kuzvinhu zvose zvinotakura uwandu.
Zvinhu zviviri zvine mirwi yakasiyana-siyana iri munzvimbo yechadenga zvinosungirwa kupesvedzerana zvakaenzanirana nehukuru hwazvo. Kubva pachiitiko ichocho, ndipo panomuka pfungwa yesimba regiravhiti.
Kuvapo kwehuremu (M) muchikamu chakapihwa muchadenga, inogadzira shanduko mugwara remimwe miviri ine huwandu (m). Kana "m" akaswedera pedyo zvakakwana kusvika "M", kufamba kwayo kuchakanganiswa zvakanyanya zvichienderana nekuwanda kwezvose zviri zviviri.
Seri kwesimba rakadaro kune simba regiravhiti, muparidzi mukuru wekudyidzana kunowanzoitika. Kusimba kana mwero wekukwezva kwenzvimbo yesimba rinokwevera inosiyana zvichienderana nekuwanda kwechinhu chimwe nechimwe.
Kudyidzana uku, maererano nedzidziso yerelativity, vanokwanisawo kuchinja nguva. Kana iyo dhigirii kana kusimba kwakakwira, ivo vanokwanisa kuikanganisa, kufambisa humwe humwe kana kugadzira maburi matema. Vekupedzisira ndivo vakweretesi venzvimbo yegiravhiti ine simba kwazvo zvekuti hapana kana chiedza chinobuda mairi.
Pasina mubvunzo, kuburikidza nemunda wegiravhiti uye maitiro ayo, chidzidzo chekudyidzana uku chakarerutswa. Kunyange zvakadaro, kuwana tsinhirano pakati pomutemo weboka raNewton nomutemo waEinstein wokuti relativistic mutemo uripo ibasa rinofanira kuitwa.
Iyo Gravitational Field Formula
Muitiro wendima yegiraviti ndiyo inogadza mwero wekusimba kwehumwechete. Simba renzvimbo yegiraviti isimba rinoitwa negiravhiti rinobva pa kukurumidza kwayo pamusoro pechinhu chakapihwa.
Tsanangudzo iyi inozivikanwawo sekukwidzwa kwegiravhiti, iko kurudziro huru pakudyidzana kukuru. Nokuda kwekumiririra kwayo, chiratidzo g pakushandisa equation.
Zvakare, iyi fomula inoiswa mukati meiyo vector ndege, panzvimbo yekukakavadzana zvinoenderana nerelativistic theory. Saka, inorangarira mitsetse ine pfungwa negwara pakuisa formula.
Mhedzisiro yeformula iyi inoratidzwa mukati newtons anenge makirogiramu. Uye, sezvazviri, inotsanangurwa se "simba payuniti misa inoonekwa nechidimbu pamberi pekugoverwa kwevanhu vazhinji".
Uyezve, iyo equation inowedzera mamwe mavhezheni ayo anokonzerwa nekugadzira kuverenga kwakaringana. Pano, musiyano "m" wakavharwa iro rinoreva kuti test mass; uye, “f”, inomiririra simba.
Mienzaniso kana zviitwa zvesimba rinokwevera zvinhu pasi. Zorora pfungwa dzako nezvikumbiro izvi!

Mumwe wemienzaniso yakajairika kana maekisesaizi emunda wegiravhiti kudzidzisa mhedzisiro yawo kutora Solar System sereferensi. Nekuda kwehuwandu hweZuva, kukwezva kwegiravhiti kunobvumira kutenderera kunogara kuchitenderera kuritenderedza.
Mune mamwe mazwi, Simba rinokweva rezuva reZuva rinopesvedzera zvakananga mapuraneti. Nekuda kweizvozvo, mafambiro emitumbi yekudenga anoenderana nechinhu ichi sezvakadaro.
Mumwe muenzaniso kana kuti kushandisa simba regiravhiti isimba rinokweva repasi chairo reNyika. Nehuremu hwe5974 x 1024 kg, zvakaipoteredza zvakanyanya kukanganiswa negiravhiti.
Nokungosvetuka kana kudonhedza chero chinhu pasi, pupurira kusimba kwegiravhiti pakati penyika. Nekukwidziridzwa kwegiravhiti zvakanyanya kana kushoma kwakatemwa pa9,8 m/s, mhedzisiro yaro inoita seyakanyanya kana kusimba.
