Ukuhlobana ezinyakazayo mechanical

Lokhu legatsha physics njengoba Mechanics, iye ukutadisha ukuxhumana kanye ukunyakaza zemizimba. Isici esiyinhloko ukunyakaza esivusa emkhathini. Kodwa inhlangano uqobo ngoba izingqapheli ezahlukene kuzohluka - lena kwezinto motion lokukhanda. Lapho umuntu emi eceleni komgwaqo nokubuka imoto ezihambayo, sibona ukuthi ukhona noma useduze nathi, noma zisuswe, kuncike isiqondiso motion.

Ukubuka ukuhamba umshini, siluthola kanjani ibanga phakathi obuka futhi imoto. Ngesikhathi esifanayo, uma sihlezi emotweni futhi phambi kwethu kuyoba ijubane lokukhanya alishintshi ukuhambisa enye imoto, ngaphambili uzobe waqonda njengoba emi endaweni, ngoba ibanga ayishintshi phakathi imishini. Kusukela umbono obukele imi komgwaqo imoto ihamba, ngokuya abagibeli - imoto emile.

Lokhu kusikisela ukuthi ingqapheli ngamunye ukunyakaza kulinganiselwa ngendlela yalo, okusho kwezinto ezinyakazayo mechanical kunqunywa iphuzu kuyiphi observation kwenziwe. Ngakho-ke, ngenxa yokuzimisela olunembile ezinyakazayo umzimba kuyadingeka ukuze ukhethe iphuzu (umzimba), okuyiqembu ukulinganisa ezinyakazayo kuyobe kwenziwe. Lapha yezimo abhekene kukhona umcabango wokuthi ngale ndlela ekutadisheni ukunyakaza kwenza kube nzima ukuwaqonda. Kwenza ufuna ukuthola esithile, lapho libhekwa sinyathelo kungaba "ngokuphelele" hhayi isihlobo.

Ngokutadisha le kwezinto motion, i-physics, futhi sasizama ukuthola ikhambi lale nkinga. Ososayensi, abasebenzisa ngayo amazwi anjengokuthi "ezinyakazayo rectilinear iyunifomu" futhi "isivinini ukunyakazisa umzimba," ezama ukuthola indlela umzimba izoya isihlobo umuntu obuka, ngesivinini ezahlukene. Ngenxa yalokho, kwatholakala ukuthi umphumela observation incike isilinganiso velocity ezinyakazayo isihlobo umzimba ukuze ngamunye abanye abaqaphile. Uma Isivinini yomzimba, bese-ke isuswe uma incane, khona-ke kuyeza.

Ukuze zonke izibalo amafomula of Mechanics classical, yokuxhuma isivinini, ibanga kanye nesikhathi siyahamba iyunifomu. Isiphetho elandelayo kusikisela ngokwayo: kwezinto motion mechanical - lena umqondo ukuthi kusho nenkathi efanayo isikhathi obuka ngamunye. Izimfundiso ifomula ngokuthi uGalileo kugucuka. Yena waqala e Mechanics classical washayelwa nomqondo kwezinto motion.

Okwakushiwo ezingokomzimba kugucuka waseGalile ijulile kakhulu. Ngokusho Mechanics classical, ifomula zayo akuzona kuphela Emhlabeni kodwa kuyo yonke indawo. Isiphetho ezilandelayo kusuka kulolu - ngokulinganayo isikhala (nombala) lonke. Futhi uma ezinyakazayo ngokulinganayo kuzo zonke izindawo, isikhala anezakhi isotropic, ngamanye amazwi, impahla yayo ayafana kuzo zonke izindawo.

Ngakho, kuvela ukuthi iningi elula imihlola mechanical, rectilinear ezinyakazayo iyunifomu umqondo motion mechanical, ukuba okwatholakala ebaluleke kakhulu (noma umbono): welithi "isikhathi" kuyinto eyodwa yawo wonke, okungukuthi, kuba jikelele. Futhi, kusobala ukuthi Isikhala isotropic futhi eyohlobo, futhi lokho kuguqulwa uGalileo evumelekile kuyo yonke indawo.

Nazi ezinye iziphetho engavamile etholakala ngokubheka kusukela ohlangothini imoto eyayidlula, kanye imizamo amafomula of Mechanics classical, isivinini kunenze nisondelane, indlela nesikhathi ukuthola incazelo yalokho akubona. Umqondo okulula "kwezinto motion mechanical," kuvela, kungaholela iziphetho global ezithinta nolwazi oluyisisekelo lokuthi indawo yonke.

Ngokuqondene nezindaba impahla physics classical. Imibuzo exhunywe ne kwezinto motion mechanical iziphetho ulandele kusukela lo mqondo.
