Nguva zhinji isu vanhu takajaira kufamba, kusvetuka nekufamba paNyika tisingafungi nezvenyaya dzakadai, semudzidziso yegiravhiti. Zvisinei, iyi isimba rinokosha refizikiki, uye harina kufanana pane imwe nyika, nenzira imwechete iyo inoderera zvakanyanya mu cosmic vacuum kusvika 0. Ichi ndicho chikonzero chero cosmos, the kukosha kwesimba rinokwevera zvinhu pasi pamapuraneti vakasiyana zvachose.
Mupfungwa iyi, simba rinokwevera zvinhu pasi rinoenderana nehukuru. Ichi ndicho chikonzero, tichifunga kuti Nyika ine simba regiravhiti re9.8 m/s2, chinhu chinodonha chakananga kupasi redu chine kumhanya kwemamita 9.8 pasekondi mukudonha kwemahara. Zvino, nhamba yacho ingave yei mune dzimwe nyika, nyeredzi kana makwara enzou? Zvakanaka, muchinyorwa chino ndichataura newe chaizvo pamusoro peizvi, Kukosha kwegiravhiti pamapuraneti.
Kukosha kwegiravhiti pamapuraneti
Nezve pamusoro, Kukosha kwegiravhiti mu mapuraneti, anotevera:
giravhiti pane mercury
Kubva paradius ye Mercury ingori makiromita 2440 chete, uye huremu hwayo idiki zvikuru pane yePasi, ine giravhiti rekunze re3.7 m/s2. Mune mamwe mazwi, 1 gramu mu Nyika yakakosha 0,38 magiramu munyeredzi yekutanga yeSolar System.
Gravity paVenus
Venus Ndiyo nyika inotora nzvimbo yechipiri ye Solar system uye yakanyanya kufanana nePasi muhukuru nemhepo yakakora. Zviri pachena kuti simba regiravhiti ikoko richave rakanyanya kufanana neredu, nhamba iri 8.87 m/s2.
giravhiti pamwedzi
Nekune rumwe rutivi, kukosha kwegiravhiti pamapuraneti kwakakosha, asi zvakakoshawo kutsanangura nzira iyo simba rinokwevera pasi riri papasi. mwedzi. Ndosaka zvichionekwa kuti giravhiti reiyi rakaderera kakapetwa ka6 pane rePasi, kureva kuti, kana tikatsika pamusoro pemwedzi hatingakwanise kufamba nenzira yakafanana neyepasi redu nekuda kweiyo shanduko yakakosha inoitika. kumativi ose simba regiravhiti.
Nenzira yakafanana, taizofamba nokusvetuka, sezvo muviri wedu uchinzwa wakareruka zvikuru. Kupa muenzaniso, munhu ari panyika anorema 60 kg, pa Luna aizorema 10kg. Ndicho chikonzero nei vazivi venyeredzi vakaisa tsoka paMwedzi vakashandisa masutu chaiwo, kuitira kuti miviri yavo isava yakanyanyisa uye inoyangarara, pamwe chete nemigumisiro yose iyo kuchinja kwechisimba kwakadaro munharaunda iyo inoimbundira inopikisa kune chipenyu.
Mwedzi Gravity Results
Kubwinya kweMwedzi kunokwezva mvura yemakungwa nemakungwa, kunonakidza masaisai ambotaurwa. Zvekuti isu tifunge zvishoma, masaisai ndiko kukwidziridzwa uye kudonha kwemvura yegungwa kunotanga kakawanda pazuva. Nokudaro, Mwedzi unogadzira mafungu maviri: mafungu akakwirira kana kuti mafungu akakwirira, inova nguva iyo mvura inosvika pakukwirira kwayo; uye kuderera kwemvura kana kuderera kwemvura, inova nguva iyo mvura inosvika pakureba kwayo kudiki.
giravhiti paMars
El nyika Mars inosanganisira akawanda typologies nePasi. Iwo mapuraneti maviri ane huwandu hwakafanana hwenzvimbo yepasi, ane polar caps, uye ese ari maviri anonakidzwa neakaenzana ikozvino pamasemo avo anotenderera, rimwe nerimwe richikonzera kusimba kwemwaka. Panguva imwe cheteyo, mapuraneti ose ari maviri anoratidza chokwadi chakasimba chokuti akaita shanduko dzemuchadenga munguva dzekare.
Panguva imwe chete, mapuraneti maviri aya haana kuenzana zvakanyanya, uye muhuwandu hwakakosha hwezviso. Semuenzaniso, kumanikidzwa kwemhepo paMars kunongova chikamu chimwe chete cheiyo paNyika, pakati pe7,5 millibars pa. Mars, uye nePasi kungopfuura 1000. Avhareji yetembiricha yepasi yakadererawo paMars, igere panzvimbo inotonhora -63°C, mukuenzanisa ne14°C paNyika. Uye nepo kupfuurira kwezuva reMartian kunenge kwakangofanana, kupfuurira kwegore reMartian kunowedzerwa zvine mutsindo, kuva anenge mazuva 687.
Asi musiyano mukuru pakati pemapuraneti maviri ndewekuti munzvimbo yeMars simba rinokwevera zvinhu pasi harina kusimba pane rePasi, 62% zvishoma kuti rive chairo. Munhu anorema 100 kg paNyika aizoyera 38 kg chete paMars.
Kusiyana kwesimba rinokwevera pamusoro pedenga uku kunokonzerwa nehuwandu hwezvinhu zvisina kuenzana zvakaita sehukuru, density, uye radius yepasi. Kunyange zvazvo Mars iine nzvimbo yakada kufanana nePasi, inongova hafu yedhayamita yepasi redu uye haina kuenderana. Kureva, Mars ine chikamu che15% chemuviri wePasi uye 11% yehuwandu hwayo.
Vesainzi vakafungidzira giravhiti reMars zvichibva papfungwa yaNewton yegiravity, iyo inotaura kuti simba rinokweva rinoitwa nechinhu rakaenzana nehuremu hwacho. Kana mutumbi wakatenderera wakaita sepasi rine huremu hwakapihwa (munyaya iyi, Mars) ukashandiswa, giravhiti repamusoro rinenge richida kuenzana neskweya yeradius yayo. Kana mutumbi wedenderedzwa une avhareji density yakapihwa ukashandiswa, inova yakati wandei kana kushomeka zvinoenderana neradius yako.
Mars ine huremu hunosvika 6,4185 x 10^23 kg, hunova hunenge 0,107 kuenzana nehukuru hwePasi. Nenzira imwecheteyo, inowana avhareji radius ye3.390 km, iyo yakakosha inosvika 0,532 terrestrial radii. Naizvozvo, giravhiti pamusoro pe Marte inogona kutaurwa chaizvo se: 0.107 / 0.532 ^ 2, kubva kwatinowana kukosha kwe0,38. Kureva kuti yaizova nekumhanya kwemamita 3,724 pasekondi.
Kupinda kweMars giravhiti uye mhedzisiro yayo pa zvisikwa zvepanyika inhanho yekutanga yakakosha kana tichida kutumira vazivi vemuchadenga, nyanzvi, uye kunyange makoroni rimwe zuva. Zvine hutsinye, mhedzisiro yekuratidzwa kwenguva refu pasimba rinokwevera zvinhu pasi, iri zvishoma pamusoro pechikamu chimwe muzvitatu chePasi, ichave chinhu chakakosha chechero chinangwa chiri kuuya chinoitwa basa kana zviitiko zvekoloni.
giravhiti pajupiter
Zvino, panguva ino tinosvika kune makuru makuru eSolar System. Tinomutangira jupiter inotyisa. Iyi nyika hombe yegasi ine huremu hukuru, asi kwete nzvimbo yakasimba. Zvakadaro, mufungidziro yemukati kati, simba rinokwevera zvinhu pasi rinotyisa pa24.8 m/s2. Mune mamwe mazwi, kanenge katatu paNyika.
giravhiti pasaturn
Isu tave kuenda kupasi rechipiri rakakura muSolar System, Saturn. Yakasimba kwazvo asi isina kuonda kwazvo, uye zvakare gasi, simba rayo rinokwevera zvinhu pasi rakanyanya kufanana nesu, re10.44 m/s2.
Gravity paUranus
Ikozvino Kukosha kwegiravhiti pamapuraneti, kunyanya mu Uranus sezvo hofori yegasi iyi ine density yakaderera, saka nenzira imwechete ine simba rinokwevera zvinhu rakada kufanana nerePasi. Nyika, iri 8.7 m/s2, kunyange yakaderera pane yedu pasinei nehukuru hwayo 4 yakakura kudarika nyika yedu.
giravhiti paNeptune
Pakupedzisira, iyo yekupedzisira uye yakanyanya kuparadzaniswa yepasi resolar system Neptune, imba huru kupfuura dzose. Kukura zvakapetwa ka17 pane Earth, zvakare yakatetepa zvakanyanya, saka simba rinokwevera zvinhu pasi rinongori 11.15 m/s2, rakati kurei kupfuura pano.
Saka ndinovimba kuti zvave zvakakosha kwauri kuti uzive kukosha kwegiravhiti mukati mapuraneti.
