Space velocity

Chero chinhu chipi zvacho, chichikandwa kumusoro, nokukurumidza kana kuti gare gare chiri pasi penyika, kana iri ibwe, chidimbu chepepa kana pete nyore. Panguva imwecheteyo, shanduro yakaendeswa munzvimbo yehafu yezana remakore yapfuura, nzvimbo yekugara kana Mwedzi inoramba ichifambisa mumakwara ayo, sekunge simba rekuvhenekera kwenyika yedu risingashandi zvachose. Sei izvi zvichiitika? Sei Mwedzi usingaiti kuwira pasi, uye Nyika haifaniri kuenda kuSuva? Ichokwadi here kuti havasi ivo vanowanikwa pasi rose?

Kubva muchikoro chechikoro chefizikiki, tinoziva kuti kudengenyeka kwepasi rose kunobata muviri chero upi zvawo. Zvino zvingava zvine musoro kufunga kuti kune rimwe simba rinosunungura simba remhepo. Simba iri rinowanzoti centrifugal. Chiito chayo chiri nyore kunzwa nechisungirirwa mutoro muduku kusvika kune rumwe rutivi rwetambo uye hausati wadzikomberedza kumativi ose. Panguva imwecheteyo, yakasimudza kasi yekutenderera, yakasimba kusimba kwetambo, uye inononoka mutoro, inowedzera kuwira.

Nokudaro, tauya zvikuru pedyo nepfungwa ye "cosmic speed". Muchidimbu, rinogona kurondedzerwa sechibvumirano chinobvumira chero chinhu chipi zvacho kuti chikunde kukudzwa kwemuviri wekumatenga. Sezvo muviri wekumatenga , nyika, saratani, yezuva kana imwe nzira inogona kuita. Iyo nzvimbo velocity iri pane chimwe chinhu, icho chinofamba munzira. Nenzira, ukuru uye chimiro chemhirizhonga chechinhu chinzvimbo chinoenderana nekukura uye kutungamirirwa kwekukurumidza icho chinhu chakapiwa chinogamuchirwa panguva yekubvisa injini, uye kukwirira kwacho chiitiko chacho chakaitika.

Space velocity ndeyemarudzi mana. Zviduku pane zvadzo ndezvokutanga. Iyi ndiyo duku shomanana iyo chipfeko chinofanira kunge chichifanira kupinda muhombodo dzakatenderera. Kukosha kwaro kunogona kutsanangurwa nehuwandu hwekuita:

V1 = √mu / r, kupi

Μ is the geocentric gravitational constant (μ = 398603 * 10 (9) m3 / s2);

R iyo iri kure kubva pakurongwa kwekutanga kusvika pakati pePasi.

Nokuda kwekuti chimiro chepasi redu haisi bhora rakanaka (pamapuranga rakanyatsorongedzwa), kureba kubva pakati nepakati kumusoro ndiko kunyanya kuEricator - 6378.1 • 10 (3) m, uye zvishoma pamatanda - 6356.8 • 10 (3) m. Kana tikatora muwandu wekukosha - 6371 • 10 (3) m, tinowana V1 yakaenzana ne7,91 km / s.

Izvo zvakanyanya cosmic speed zvichanyanya kukosha kweiyo, humwe huwandu hwakakonzerwa huchawanikwa kuburikidza nehupenyu, huchibva kure Pasi nokuda kwekuraira. Pane imwe nguva, iyo nzira inoputika, inotora chimiro chemufananidzo, uye iyo ndege ichaenda kurima nzvimbo expanses. Kuti tisiyane nenyika, ngarava inofanira kuva nechipiri chekudenga. Inogona kuverengerwa nemurairo V2 = √2μ / r. Nokuda kwepasi redu, kukosha uku ndiko 11.2 km / s.

Nyanzvi dzenyeredzi dzakare kare dzakatsanangura kuti chii chinonzi cosmic speed, zvose zvekutanga uye yechipiri, kune imwe nyika yepasi redu. Hazvisi zvakaoma kuzviverenga nemazwi aya pamusoro apa kana tikatsiva nguva inogara μ nemufananidzo fM, apo M ndiwo mashoma emuviri wekudenga unofadza, uye f ndiyo nguva inopisa (f = 6.673 x 10 (-11) m3 / (kgx2).

Chechitatu cosmic speed inobvumira chero chipfeko chinokonzera kukurira kwezuva uye kubva muzvarwa reSolar system. Kana tikazviverenga tichiremekedza zuva, tinowana 42.1 km / s. Uye kuti uwane kubva kuNyika kusvika kune-pedo-solar, iwe unofanirwa kukurumidza kusvika 166 km / s.

Zvakanaka, pakupedzisira, yechina nzvimbo velocity. Nekubatsira kwayo, iwe unogona kukurira kukwezva zvakananga kune garaxy pachako. Kubwinya kwaro kunopesana zvichienderana nehutano hwegaraxi. Nokuda kweMirai Yedu, iyi inokosha inosvika 550 km / s (kana yakaverengwa maererano neSuva).
