Kev ntsuas thiab Kev ntsuas Chav nyob hauv Physics . Kev ntsuas yog ib qho txheej txheem ntawm kev txheeb xyuas qhov tsis paub lub cev muaj nuj nqis los ntawm kev siv tus qauv kom muaj nuj nqis. Piv txwv li: Nqa ib phau ntawv thiab siv tus pas ntsuas (nplai) kom pom nws qhov ntev. Koj tau dhau los ntawm tus txheej txheem hu ua Kev ntsuas qhov twg: Qhov tsis paub lub cev muaj nuj nqis yog qhov ntev ntawm phau ntawv.

Piv txwv li, txhais li cas los ntawm kev ntsuas hauv physics?

Txhais : " Kev ntsuas "yog qhov kev txiav txim siab ntawm qhov loj lossis qhov loj ntawm ib yam dab tsi. Los ntawm kev sib piv cov khoom tsis paub nrog qee qhov qauv ntawm qhov sib npaug, hu ua ntsuas chav tsev. Kev ntsuas tuaj yeem yog txhais raws li "Kev sib piv ntawm ib qho tsis paub ntau nrog qee qhov paub txog qhov zoo tib yam".

Qhov thib ob, qhov ntsuas hauv science yog dab tsi? Hauv kev kawm , a ntsuas yog ib phau ntawm cov ntaub ntawv ntau lossis cov lej uas piav qhia txog cov khoom ntawm ib qho khoom lossis qhov xwm txheej. A ntsuas yog tsim los ntawm kev sib piv ib qho kom muaj nuj nqis nrog cov qauv ntsuas. Kev kawm ntawm ntsuas hu ua metrology.

Tsis tas li ntawd, vim li cas kev ntsuas tseem ceeb hauv physics?

Nej twb pom lawm ntsuas yog tseem ceeb hauv physics vim nws ua rau peb siv lej hauv kev sib cav; nws kuj yog tseem ceeb vim tias cov lej feem ntau yog qhov yooj yim tshaj plaws, compact ancl yam tsawg kawg nkaus ntawm kev sawv cev kev paub thaum peb xav khaws nws thiab sib txuas lus.

Dab tsi yog standard unit physics?

Qhov yooj yim mechanical units yog cov. Tag nrho cov khoom siv hluav taws xob tuaj yeem qhia tau ntawm peb qhov ntau. Cov txheem units yog Systeme Internationale lossis SI units . Primary SI units rau mechanics yog kilogram (mas), lub 'meter' (ntev) thiab thib ob (lub sij hawm).
