A kom muaj nuj nqis uas muaj qhov loj tab sis tsis muaj kev taw qhia tshwj xeeb tau piav qhia raws li scalar. Ib qhov ntau uas muaj qhov loj thiab ua haujlwm hauv ib qho kev taw qhia tshwj xeeb tau piav qhia raws li vector.
Vim li cas scalar kom muaj nuj nqis tsis muaj kev taw qhia?
Xav txog nws li no - cov kev taw qhia ntawm tam sim no yog txhais txheeb ze rau qee yam khoom. Tam sim no nyob rau hauv ib tug hlau yog obviously ib tug scalar, thiab nws yuav tsum tau ib tug, txij li thaum nws tsis ua raws li cov cai ntawm vector ntxiv Kev taw qhia ntawm ib qho scalar yuav txhais tau ntev npaum li nws qhov loj. tsis yog xoom, thiab tus nqi yuav yog +1 lossis -1.
Tus lej ntsuas puas tuaj yeem cuam tshuam nrog kev taw qhia?
Scalar ntau muab a qhov ntau, thaum vector ntau muab qhov loj thiab kev taw qhia. Cov lus teb yuav yog ib qho kev ntsuas uas yuav tsum tau ua nyob rau hauv ib qho kev taw qhia. Qhov deb yog qhov ntsuas qhov ntev, tsis hais qhov kev taw qhia.
Pob scalers muaj nrug?
Nyob deb yog a scalar quantity uas yog hais txog "ntau npaum li cas av ib yam khoom tau npog" thaum nws txav. Displacement yog ib tug vector kom muaj nuj nqis uas hais txog "yuav deb npaum li cas ntawm qhov chaw ntawm qhov khoom yog"; nws yog qhov khoom hloov tag nrho hauv txoj hauj lwm.
Puas kev taw qhia yog vector lossis scalar?
A vector kom muaj nuj nqis muaj kev taw qhia thiab qhov loj, thaum lub ntsuas ntsuas 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. Piv txwv li: Kev nrawm yog qhov ntau npaum li cas, tab sis qhov nrawm yog vector uas qhia txog ob qho tib si kev taw qhia thiab qhov loj.
