Dab tsi yog qhov txawv ntawm a scalar thiab vector ? A vector Qhov ntau muaj qhov taw qhia thiab qhov loj, thaum a scalar tsuas muaj qhov loj. Koj tuaj yeem qhia yog tias muaj ntau npaum li cas vector los ntawm seb nws puas muaj kev taw qhia cuam tshuam nrog nws.

Xav txog qhov no, dab tsi yog scalar thiab vector nrog piv txwv?

Scalar Quantities: Lub cev muaj nuj nqis uas tau teev nrog qhov loj lossis loj ib leeg yog scalar qhov ntau. Rau piv txwv , ntev, ceev, ua haujlwm, huab hwm coj, ceev, thiab lwm yam. Vector Ntim: Vector quantities xa mus rau lub cev qhov ntau npaum li cas los ntawm lub xub ntiag ntawm ob qho tib si magnitude thiab kev taw qhia.

Ib yam li ntawd, dab tsi yog vector kom muaj nuj nqis? Vector , hauv physics, a kom muaj nuj nqis uas muaj ob qhov loj thiab kev coj. Nws yog feem ntau sawv cev los ntawm ib tug xub uas nws cov kev taw qhia yog tib yam li cov kom muaj nuj nqis thiab nws qhov ntev yog proportional rau lub kom muaj nuj nqis qhov loj.

Tom qab ntawd, dab tsi yog scalar thiab vector?

Cov kom muaj nuj nqis yog a 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 qhov ntau uas tau piav qhia tag nrho los ntawm qhov loj (lossis tus nqi lej) ib leeg. Vectors yog qhov ntau uas tau piav qhia tag nrho los ntawm qhov loj thiab qhov taw qhia.

Lub sij hawm yog scalar lossis vector?

A vector yog a scalar nrog kev taw qhia. Yog li Sijhawm tuaj yeem yog a vector , tab sis nws txhais li cas yog nyob ntawm cov ntsiab lus teb. Hauv 1D nws tsuas muaj 2 cov lus qhia, zoo thiab tsis zoo nrog xoom ua qhov zoo.
