A hloov chaw yog a vector nws qhov ntev yog qhov luv tshaj plaws ntawm qhov pib mus rau qhov kawg txoj hauj lwm ntawm apoint P. Nws quantifies ob qhov kev ncua deb thiab kev taw qhia ntawm animaginary motion raws ib txoj kab ncaj nraim los ntawm thawj txoj hauj lwm mus rau qhov kawg txoj hauj lwm ntawm lub point.

Tom qab ntawd, kev hloov pauv hauv cov lus yooj yim yog dab tsi?

Cov kev txav chaw txhais tau hais tias ib yam khoom tau tsiv, los yog tau lawm hloov chaw . Kev khiav tawm txhais tau tias yog qhov kev hloov ntawm txoj hauj lwm ntawm ib yam khoom.

Tsis tas li ntawd, kev hloov pauv yog dab tsi piav qhia nrog piv txwv? Piv txwv li: yog peb xav tib yam piv txwv raws li tau hais ua ntej, tag nrho hloov chaw ntawm cov khoom yuav yog qhov ntev ntawm txoj kab koom nrog ob txoj haujlwm. Cov hloov chaw ntawm ib yam khoom feem ntau luv dua los yog sib npaug rau qhov deb ntawm qhov khoom.

Kuj kom paub, dab tsi yog qhov sib npaug vector?

Sib npaug vectors yog cov duab uas muaj tib qhov loj thiab tib qhov kev taw qhia. Sib npaug vectors tej zaum yuav pib ntawm txoj haujlwm sib txawv. Nco ntsoov tias thaum lub cov duab yog sib npaug , cov directed kab ntu yog parallel. Equality OfColumn Vectors . Yog ob cov duab yog sib npaug tom qab ntawd lawv vector kem yog sib npaug

Dab tsi yog qhov kev txhais zoo tshaj ntawm kev hloov pauv?

Kev khiav tawm (symbolized d lossis s), tseem hu ua qhov ntev lossis qhov nrug, yog ib qho ntawm qhov ntau uas sawv cev rau qhov sib cais ntawm ob txhais cov ntsiab lus. Piv txwv li, peb yuav hais txog qhov kev ncua deb ntawm nruab nrab ntawm lub ntiaj teb thiab anorbiting satellite, thiab ntsuas nws li 13, 000, 000meters.
