Muab cov lej ntawm qhov muaj nuj nqis rau lub cev thiab qhov sib npaug ntawm lub hauv paus ntsiab lus tso cai rau peb nkag siab qhov xwm txheej tob dua li qhov kev piav qhia zoo ib leeg. … Kev ntsuas ntawm lub cev muaj nuj nqis yog qhia tawm hauv cov ntsiab lus, uas yog tus qauv tsim nyog.
Dab tsi yog lub cev muaj nuj nqis hauv physics?
Lub cev qhov tseem ceeb yog:
- Length.
- Mass.
- sijhawm.
- hluav taws xob tam sim no.
- Kub.
- Ntau yam khoom.
- Luminous Intensity.
- dav hlau kaum.
Qhov twg yog qhov tseem ceeb siv hauv physics?
Tam sim no SI muaj xya lub hauv paus: sijhawm, ntev, huab hwm coj, hluav taws xob tam sim no, qhov kub thiab txias, tus nqi ntawm cov khoom siv, thiab kev siv luminous.
Lub physics ntawm qhov ntau npaum li cas?
Ib lub cev kom muaj nuj nqis tuaj yeem qhia tau tias yog tus nqi, uas yog algebraic sib npaug ntawm tus lej tus nqi thiab chav tsev. Piv txwv li, lub cev qhov hnyav tuaj yeem suav tias yog n kg, qhov twg n yog tus lej tus nqi thiab kg yog chav tsev. Lub cev kom muaj nuj nqis muaj tsawg kawg yog ob tus yam ntxwv sib xws.
Qhov ntau npaum li cas yog siv los piav txog cov cai ntawm physics?
Quantities uas yog siv los piav txog txoj cai ntawm physics hu ua lub cev ntau. Muaj xya qhov tseem ceeb hauv SI system - Length (Metre),Loj (Kilogram), Lub Sijhawm (thib ob), Hluav Taws Xob (Ampere), Kub (Kelvin), Luminous siv (Candela) thiab Cov Khoom Siv (Mole).
