Vector, hauv physics, ib qhov ntau uas muaj ob qhov loj thiab kev taw qhia. … Piv txwv li, kev khiav tawm, tshaj tawm, thiab acceleration yog vector kom muaj nuj nqis, thaum ceev (qhov loj ntawm kev tshaj tawm), lub sij hawm, thiab loj yog scalars.
Koj tuaj yeem qhia tau li cas yog tias qhov ntau yog 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 cov kev taw qhia cuam tshuam nrog nwsPiv txwv: Kev nrawm yog qhov ntsuas ntau, tab sis tshaj tawm yog vector uas qhia txog ob qho kev taw qhia thiab raws li qhov loj.
piv txwv ntawm vector ntau npaum li cas?
Lub cev qhov ntau tau teev meej los ntawm kev muab ntau chav nyob (qhov loj me) thiab kev taw qhia yog hu ua vector ntau. Piv txwv ntawm vector ntau suav nrog tawm, tshaj tawm, txoj haujlwm, quab yuam, thiab torque.
Vector quantity answer yog dab tsi?
Kev piav qhia: Scalar kom muaj nuj nqis muab qhov loj, thaum vector ntau muab qhov loj thiab kev taw qhia. Cov lus teb yuav yog ib qho kev ntsuas uas yuav tsum ua raws li kev coj ua.
Lub tsheb puas yog vector ntau?
Vim kev hloov pauv yog tus vector kom muaj nuj nqis, kev coj ntawm lub tsheb pab peb nrhiav kev daws teeb meem. … Qhov kev hloov ntawm lub tsheb yog 10 units [sab hnub tuaj]. Muaj qhov sib txawv ntawm qhov loj ntawm ob lo lus teb.
