Ceev yog qhov ntau npaum li cas - nws yog qhov hloov pauv ntawm qhov kev ncua deb mus los ntawm ib qho khoom, thaum qhov nrawm yog vector kom muaj nuj nqis - nws yog nrawm ntawm ib qho khoom hauv ib qho kev taw qhia.

Vector ntau npaum li cas?

Veocity as a Vector Quantity

Velocity is a vector quantity that refers to " tus nqi uas ib yam khoom hloov nws txoj hauj lwm." Xav txog tias ib tug neeg tsiv mus sai - ib kauj ruam rau pem hauv ntej thiab ib kauj ruam rov qab - ib txwm rov qab mus rau qhov qub pib.

Vim li cas qhov nrawm suav tias yog vector kom muaj nuj nqis?

Veocity muaj ob qhov loj thiab kev taw qhia yog vim li cas nws yog vector kom muaj nuj nqis. Whereas, Ceev tsuas muaj qhov loj thiab tsis muaj kev taw qhia yog vim li cas nws yog ib qho scalar ntau.

Puas tshaj tawm yog piv txwv ntawm vector kom muaj nuj nqis?

Piv txwv li, kev txav chaw, nrawm, thiab nrawm yog vector kom muaj nuj nqis, thaum nrawm (qhov dav ntawm qhov nrawm), lub sijhawm, thiab huab hwm coj yog ntsuas. Yuav kom tsim nyog raws li ib tug vector, ib tug kom muaj nuj nqis loj thiab kev taw qhia yuav tsum tau ua raws li tej kev cai ntawm kev sib txuas.

Puas tshaj tawm ntawm huab cua yog vector kom muaj nuj nqis?

Qhov nrawm yog a vector teb, vim qhov nrawm yog vector (muaj qhov loj thiab kev taw qhia), thiab muaj qhov nrawm cuam tshuam nrog txhua qhov chaw hauv huab cua.
