Kwezinto motion mechanical

Le yesebe physics njengoko ukukhanda, sele bafunda intsebenziswano kunye nentshukumo lwemizimba. Eyona iphambili intshukumo intshukumo esithubeni. Kodwa intshukumo ngokwayo ababukeleyo ahlukeneyo ziya kwahluka - oku kwezinto sesindululo ngoomatshini. Simi ecaleni kwendlela usabukele imoto ihambe, siyabona ukuba nguye okanye luyondelelene kuthi, okanye isuswe, kuxhomekeke kwicala sentshukumo.

Okwenzeka intshukumo kumatshini, siye sibone indlela umgama phakathi mkhanyo kunye nesithuthi. Ngelo xesha, ukuba sithe sahlala apha emotweni kwaye phambi kuthi iya kuba ngesantya enye ukuya kwenye isithuthi, ngaphambili iza waqonda ukuba imi endaweni, ngokuba Umgama akatshintshi phakathi koomatshini. Ukusuka kwinqanaba zomntu obukeleyo simi ecaleni kwendlela isithuthi ihamba, ngokwemiqathango abakhweli - isithuthi zokubhala.

Oku kubonisa ukuba njengombukeli kuqikelelwa intshukumo nganye ngendlela yaso, ie kwezinto motion mechanical ezimiselwe kwinqanaba apho mkhanya ikhutshwa phandle. Ngako oko, ngenxa yokuzimisela oluchanileyo isindululo umzimba kuyimfuneko ukukhetha ingongoma (body), apho ukulinganisela isindululo uya kwenziwa. Apha yezimo kukho ingcamango ukuba indlela enjalo ekufundweni intshukumo yenza kube nzima ukuba baqonde. Kwenza ufuna ukufumana incopho ethile, xa usibona intshukumo bekuya kuba 'lungundoqo "kwaye akazalani.

Ngokufunda le kwezinto sesindululo, inzululwazi, kwaye bazama ukufumana isisombululo kule ngxaki. Izazinzulu, esebenzisa amagama afana "isindululo rectilinear efanayo" yaye "Isantya intshukumo yomzimba," uzama ukufumanisa ukuba umzimba iza kuhamba xa kuthelekiswa okhangeleka kumbukeli, kunye ngesantya ezahlukeneyo. Ngenxa yoko, kuye kwafunyaniswa ukuba umphumo lokuqaphela kuxhomekeke lulwahlulo uqina kunye isindululo umzimba xa kuthelekiswa nezinye ababukeleyo ngamnye. Ukuba Velocity lomzimba ngakumbi, ngoko icinyiwe ukuba ngaphantsi, ngoko oko kuyeza.

Ngokuba zonke izibalo iifomyula ze ubucukubhede yamandulo, izihlanganisi isantya, umgama kunye nexesha ihamba efanayo. Esi sigqibo ilandelayo icebisa ngokwayo: kwezinto sesindululo ngomatshini - eli gama elo lithetha kwixesha elinye ixesha mkhanyo ngasinye. Iimfundiso formula ekuthiwa UGalileo zinguquko. Yena waba ngowokuqala ubucukubhede classical yaqulunqa ingqiqo kwezinto sentshukumo.

Intsingiselo yesitalato utshintshwano waseGalili yinzulu kakhulu. Ngokutsho ukukhanda classical, ifomula wayo nje kuphela Earth kodwa kuyo yonke iphela. Esi sigqibo olandelayo kule - isithuba ngokulinganayo (ngokufanayo) lonke. Kwaye kanye motion ngokulinganayo kuzo zonke iindlela, isithuba uye iipropati isotropic, ngamanye amazwi, iimpawu ayo twatse kuwo onke amacala.

Ngoko, kwenzeka ukuba eyona ilula ngezenzeko ngomatshini, eshukumayo iyunifom rectilinear kwaye ingqikelelo sesindululo ngomatshini, ukuba ibe ezingaqondakaliyo ebaluleke kakhulu (okanye hypothesis): ingqiqo ka "ixesha" yenye bonke, ie, ke yonke. Kwakhona, kulandela ukuba le ndawo kusetyenzelwa isotropic kwaye eyohlobo olulodwa, kunye nokuguqulwa uGalileo esebenzayo kuyo yonke iphela.

Nazi ezinye izigqibo engaqhelekanga ephuma mkhanya ukusuka icala imoto edlulayo, kwakunye nemizamo iifomyula ze ubucukubhede yamandulo, isantya lib, indlela kunye nexesha ukufumana ingcaciso into awayibonayo. Ingcamango elula "kwezinto sesindululo ngomatshini," kuvela, kungakhokelela kwizigqibo lwehlabathi ezichaphazela nolwazi olusisiseko iphela.

Ke zona izinto yemvelo yamandulo. Imibuzo enxulumene kwezinto sesindululo ngoomatshini kunye kwizigqibo ezilandelayo kule ngcamango.
