Yeefom - yeefom ngu ...: inkcazelo, ifomula, ingxaki

Yintoni na yeefom? Eli candelwana wokulungisa ukuba lifunda iindlela zemathematika kunye zejometri wokuchaza isindululo bezinto yengxoxo. Bengabakho iindidi eziliqela. Isihloko nqaku namhlanje uya kuba iinkalo ezinento ngandlel 'nengqiqo' yeefom ". Siza kujongana nemiba emininzi, kodwa uqale kakhulu ukuba asinguwo kwi iingqiqo esisiseko kunye nengcaciso yokuba ukusetyenziswa kwazo entsimini.

Ziziphi izinto ingqalelo?

Ukuba yeefom - na isebe ophanda ukuba lifunda iindlela ukuchaza isindululo amaziko ezahlukeneyo-izithuba, ngoko ke kufuneka ukuba zisebenze kunye imizimba ngokwabo, akunjalo? Ukuze uqonde ukuba yintoni na busemngciphekweni ngokukhawuleza, ungafumana eyenzelwe abantwana besikolo multimedia isifundo. Yeefom ukuqonda nje, ukuba ukhangela kule iziseko zayo. Xa ufunda nabo, uya kuphawula ukuba ngokwenkcazo kukho ulwazi kwicandelo physics ufunda imithetho yokuhamba amanqaku eziphathekayo. Phawula indlela jikelele ichaza izinto. Kwelinye icala, ezi ngongoma zokufunda nje kuphela ngqalelo yeefom into. Eli candelo uhlola siseko nokwakheka intshukumo kwakunye namabhunga engqongqo, kwakunye neencindi ezifanelekileyo. Amaxesha amaninzi, la magama ezintathu zidityaniswe zibe omnye, wathi nje "izinto yengxoxo." Idealization kule meko imfuneko imputation kwaye kude iimpazamo engaba ngendlela. Ukuba ukhangela le nkcazelo yencopho eziphathekayo, uya kuphawula ukuba ikuthethayo kulandelayo: umzimba, ubukhulu apho nokungahoywa kwi imeko efanelekileyo. Oku iqondwe ngolu hlobo lulandelayo: xa kuthelekiswa nomgama ohanjiweyo imilinganiselo linear yento ayinamsebenzi.

Esetyenziswa ukuchaza?

Njengoko kuchaziwe ngaphambili, yeefom - eli sub-ubucukubhede, nto leyo izifundo iindlela wokuchaza isindululo yencopho. Kodwa ukuba oku kunjalo, oko kuthetha ukwenza imisebenzi enjalo kufuneka kwezinye izinto ezisisiseko kunye nemithetho-siseko, ezifana axiomatic? Ewe. Kwaye kulo mzekelo na. Okokuqala, kule yeefom sungula umgaqo ukusombulula ingxaki, hayi ujonge imikhosi omele ingongoma eziphathekayo. Sonke siyazi ukuba umzimba kwandiswa okanye yehla yaya xa kunokwenzeka ukuba izenzo ethile amandla kuyo. Kwaye yeefom - eli candelwana ekuvumela ukuba usebenze kukukhawuleziswa. Nangona kunjalo, uhlobo amagunya asakhasayo akujongwa apha. Ukuchaza uhlalutyo motion isicelo zemathematika, le yomgama kunye nejiyometri lwendawo algebra. Kwakhona lidlale iigridi indima kwaye ilungelelanise ngokwabo. Kodwa siza sithethe kancinane emva koko.

History of indalo

Umsebenzi wokuqala kwi yeefom zazenziwe ukuya kwe-nzulu enkulu uAristotle. Ukuba idala eminye imigaqo esisiseko yale sebe. Kwaye nkqu nangona ukuba umsebenzi wakhe iziphumo ziqulathe eminye izimvo eziphosakeleyo kunye neengcamango, umsebenzi wakhe nangoku ixabiso elikhulu physics mihla. Imisebenzi Aristotle koko bafunda UGalileo Galilei. Uye kuqhutywa iimvavanyo kunye odumileyo Outcomes Tower xa ehlola regularities omzimba owela simahla. Emva kokuhlolisisa bonke ubude nobubanzi zokucinga UGalileo phantsi ukugxekwa kwizigqibo Aristotle kaThixo. Umzekelo, ukuba yokugqibela wabhala ukuba amandla - siso esibangela ukuba sesindululo, uGalileo wabonisa ukuba mandla yokunyusa unobangela, kodwa hayi ke yinto yokuba umzimba kuthatha kwaye uqalisa ukuhamba ndisishenxise. Ngokutsho Aristotle, umzimba ukwazi ukufumana isantya kuphela phantsi kweempembelelo a amandla ethile. Kodwa siyazi ukuba le mbono nto bayikholelwayo, ngenxa yokuba kukho iyunifom yomgama motion. Kwakhona oku kungqina ukuba yeefom ifomula. Kwaye ugqithele kumbuzo olandelayo.

Yeefom. Physics. nezimaphambili ezingundoqo

Kweli candelo kukho iqela imigaqo esisiseko kunye neenkcazelo. Makhe siqale ezona ziphambili.

intshukumo mechanical

Mhlawumbi, esikolweni, sizama ukubeka ingcamango yintoni ingqalelo isiphakamiso ngoomatshini. Thina ke eboniswa yonke imihla, yure nganye, njalo. intshukumo Mechanical, sicingela inkqubo okwenzeka kwisithuba ekuhambeni kwexesha, oko kukuthi utshintsho kwi indawo umzimba. Kudla kakhulu asetyenziswe kwinkqubo ka, oko kukuthi nokuba abantu, bathi, umzimba yokuqala iye yatshintsha ngokuphathelele kwindawo yesibini. Masenze ngathi kumgca yokuqala iinqwelo ezimbini thina. umqhubi yomtshangatshangiso okanye izibane yalikhanyisa - oomatshini kunye emkhontweni. Ekuqaleni utshintsho sikhundla kakade. Kwaye Wena uyakwazi ukuthetha ngayo ixesha elide kwaye usoloko udiniwe: kuthelekiswa kontanga yayo, xa kuthelekiswa kumgca wokuqala, umbukeli fixed kakhulu. Kodwa mhlawumbi ingcamango icacile. Kunjalo enokuthethwa ngabantu ababini nokuba kwicala elinye okanye ezahlukeneyo. Indawo ngamnye kubo ngokunxulumene omnye kuyahlukahlukana ngexesha ingongoma nganye.

inkqubo reference

Yeefom, physics - zonke ezi inzululwazi usebenzisa ingqiqo ebalulekileyo ezifana nenkqubo reference. Eneneni, unendima ebalulekileyo kakhulu kwaye lisetyenziswa iingxaki ezenziwayo phantse kuyo yonke indawo. inamacandelo amabini ezibalulekileyo inxulunyaniswe inkqubo yezalathiso.

Uququzelelo igridi

Laba nto ngaphezu kokuba iseti nombolo ezininzi kunye nonobumba. Ukusebenzisa inkcazo units ubhalo, sinako ukwakha ezimacala elinye okanye kumacala mabini igridi, nto leyo eza kuvumela ukuba ukusombulula iingxaki elula ngokuguqula nendawo yencopho eziphathekayo oyithengileyo yothuba elithile sexesha. Ezisetyenziswa practice igridi okuntlandlo-mbini ngezixengxe X ( "X") kunye Y ( "y"). In isithuba-ntathu wongeza esqwini Z ( "eyinkqantosi") kwaye kukho zokudubula nje uququzelelo-liyajikeleza X. amaninzi ukusebenza kunye sokuhlola. Kwaye ixesha yokuqala sidibana nabo kwisikolo samabanga aphantsi, xa siqala ukuba bazobe ubude elithile. Emva kokuphumelela akukho nto kodwa ukusetyenziswa zilungelelanise ukubonisa isiqalo nesiphelo.

Yeefom Grade 10. inani

Amaxabiso ezingundoqo ezisetyenziselwa ukusombulula iingxaki yeefom yencopho - umgama, ixesha, isantya kunye lunikezelo. Makhe sithethe ngezinto ezimbini zokugqibela ngokweenkcukacha. Zombini ezi zithethe - kumda wesangqa. Ngamanye amazwi, ukuba babe uboniso wokwamanani nje kuphela, kodwa indlela ethile ngozi. intshukumo yomzimba iya kuba kwicala apho kumda wesangqa Velocity sibhekiswe. Ngelo xesha ke kufuneka ungalibali kumda wesangqa lunikezelo, ukuba sibe ityala intshukumo olungalinganiyo. Lunikezelo ingabhekiswa kwicala elinye okanye okwahlukileyo. Ukuba unayo kwa indlela enye, umzimba uqalisa ukuhamba ngokukhawuleza kwaye ngokukhawuleza. Ukuba imiyalelo ezahlukeneyo, ukudodobala luyenzeka nto de ime. Emva koko, phambi malungana yomzimba unikezelo ukufumana isantya, ngamanye ashukume kwicala elahlukileyo. Konke oku ku umkhuba kakhulu, ibonisa ngokucacileyo kakhulu yeefom. 10 iklasi - oku ixesha xa icandelo physics kutyhilwa ngokwaneleyo.

ifomula

yeefom Formula zilula ngokwaneleyo ukuba imveliso, nikhumbule. Umzekelo, ifomula siwela ngexesha elinye okanye omnye umgama into unalo fomu ilandelayo: S = vot + AT ^ 2/2. Njengoko ubona, kwicala lasekhohlo esinayo nje umgama elifanayo. Kwicala lasekunene uyakwazi ukufumana i uqina lokuqala, kunye nexesha lunikezelo. "Plus" uphawu kumi kwemiqathango kuphela, njengoko lunikezelo kunokuthatha engenaxabiso scalar ngexesha lenkqubo unyathela into. Eneneni, yeefom ze intshukumo kuthetha ubukho olunye uhlobo isantya, sisoloko sisithi "kokuqala", "ukuphela", "ngephanyazo". isantya leso kubonakala ngexesha elithile. Ke ukuba ucinga ukuba kunjalo, ngoko amacandelo zokugqibela okanye zokuqala ayikho enye into kodwa obubonakala buso, akunjalo? Komxholo othi "yeefom" mhlawumbi yintandane phakathi Abantwana besikolo, kuba kulula kwaye unika umdla.

ezinemizekelo yemisebenzi

Kule yeefom nje, kukho iindidi yonke ngeentlobo zemisebenzi. Bonke bephela ngandlel 'ithile onxulumene isindululo yencopho eziphathekayo. Ngokomzekelo, abanye kufuna ukuba ukujonga umgama ohanjiweyo ngumzimba ngokuhamba kwexesha. Oku kwaziwa parameters ezifana uqina lokuqala kunye lunikezelo. Kwaye mhlawumbi, phambi kokuba umfundi Walimisa msebenzi, nto leyo nje enye iza kuba yimfuneko ukuchaza nokubala yokunyusa umzimba. Makhe siqwalasele umzekelo. Imoto iqala kwisigxina static. Yeyiphi indlela uya kuba nexesha ukuya imizuzwana 5, ngokungathi unikezelo ulingana eziimitha ezintathu, bahlulwe yesibini square?

Ukusombulula le ngxaki kufuneka sibe S ifomula = vot + kwi ^ 2/2. Kuyo, thina nje kufakwe data ekhoyo. Eli lunikezelo kunye nexesha. Qaphela ukuba vot elithi aye zero, kususela uqina yokuqala zero. Ngenxa yoko, sifumana impendulo lwamanani kweemitha 75. Loo nto yonke, ingxaki iyatyhilwa.

iziphumo

Ngenxa yoko, siyaqonda imigaqo esisiseko kunye neenkcazelo, wabanika umzekelo nendlela ethetha ngembali eli candelwana. Yeefom, ingqikelelo eyinkampani kwibakala lesixhenxe kwi izifundo physics, rhoqo ukuphucula phakathi relativistic (non-classical) kwicandelo.
