Qhov kom muaj nuj nqis yog ib vector los yog a scalar . Ob pawg no tuaj yeem sib txawv ntawm ib leeg los ntawm lawv cov ntsiab lus sib txawv: Scalars yog cov khoom uas tau piav qhia tag nrho los ntawm qhov loj (lossis tus lej tus nqi) ib leeg. Vectors yog qhov ntau uas tau piav qhia tag nrho los ntawm qhov loj thiab qhov taw qhia.
Kuj paub yog, dab tsi yog scalar thiab vector nrog piv txwv?
A scalar yog ib qhov ntau uas tau piav qhia tag nrho los ntawm qhov loj xwb. Nws tau piav qhia los ntawm ib tus lej xwb. Ib txhia piv txwv ntawm scalar Qhov ntau muaj xws li ceev, ntim, loj, kub, lub zog, lub zog, thiab lub sijhawm. Dab tsi yog a vector ? A vector yog ib qhov ntau uas muaj ob qhov loj thiab qhov taw qhia.
Ib yam li ntawd, qhov piv txwv scalar yog dab tsi? Scalar , lub cev kom muaj nuj nqis uas tau piav qhia tag nrho los ntawm nws qhov loj; piv txwv ntawm scalers yog ntim, ceev, ceev, zog, loj, thiab lub sij hawm. Lwm qhov ntau, xws li quab yuam thiab tshaj tawm, muaj ob qho tib si loj thiab kev taw qhia thiab hu ua vectors.
Hais txog qhov no, dab tsi yog vectors physics?
physics . Vector, hauv physics , ib qhov ntau uas muaj ob qhov loj thiab kev coj. Nws yog feem ntau sawv cev los ntawm ib tug xub uas nws txoj kev taw qhia yog tib yam li qhov ntau thiab nws qhov ntev yog proportional rau qhov ntau qhov loj.
Dab tsi yog vector nrog piv txwv?
A vector yog ib qho ntau lossis qhov tshwm sim uas muaj ob qho kev ywj pheej: qhov loj thiab kev taw qhia. Piv txwv ntawm cov duab Nyob rau hauv qhov xwm txheej yog ceev, lub zog, quab yuam, electromagnetic teb, thiab qhov hnyav. (Qhov hnyav yog lub zog tsim los ntawm kev nrawm ntawm lub ntiajteb txawj nqus ua haujlwm ntawm ib pawg.)
Pom zoo:
Puas yog txoj hauj lwm vector lossis scalar?
Txoj hauj lwm r yog vector kom muaj nuj nqis; nws muaj qhov loj thiab kev taw qhia. Velocity v yog tus nqi hloov ntawm txoj haujlwm nrog lub sijhawm, v = dr/dt. Tag nrho peb, txoj hauj lwm, tshaj tawm thiab acceleration, yog vector kom muaj nuj nqis
Dab tsi yog qhov scalar tivthaiv ntawm vector?
Lub scalar x-cov ntsiab lus ntawm ib vector tuaj yeem qhia tau tias yog cov khoom ntawm nws qhov loj me nrog cov cosine ntawm nws lub kaum sab xis, thiab cov scalar y-cov khoom tuaj yeem qhia tau tias yog cov khoom ntawm nws qhov loj me nrog lub sine ntawm nws lub kaum sab xis. Hauv ib lub dav hlau, muaj ob qhov sib npaug sib npaug
Dab tsi yog qhov tseeb vector thiab txheeb ze vector?
Thaum siv cov vector tiag tiag, tus kheej lub nkoj thiab lwm lub nkoj txav ntawm lawv qhov tseeb ceev thiab cov chav kawm. Cov vectors tseeb tuaj yeem paub qhov txawv ntawm cov hom phiaj txav mus thiab nyob ruaj khov. Cov txheeb ze vector pab nrhiav cov nkoj ntawm kev sib tsoo. Lub nkoj uas nws vector hla dhau ntawm tus kheej lub nkoj txoj haujlwm yog nyob rau hauv kev sib tsoo
Dab tsi yog node thiab Antinode hauv physics?
Node: Ib lub pas dej ua ke nrog lub nthwv dej uas lub nthwv dej muaj qhov tsawg kawg nkaus amplitude. Antinode: Ib qho taw tes raws li lub nthwv dej sawv ntsug uas cov nthwv dej muaj qhov siab tshaj plaws
Dab tsi yog qhov txawv ntawm scalar thiab vector?
Dab tsi yog qhov txawv ntawm scalar thiab vector? Ib vector kom muaj nuj nqis muaj kev taw qhia thiab qhov loj, thaum lub scalar tsuas muaj qhov loj. Koj tuaj yeem qhia tau yog tias qhov ntau yog vector los ntawm seb nws puas muaj kev taw qhia cuam tshuam nrog nws
