Hwj chim units tuaj yeem hloov mus rau zog units los ntawm kev sib npaug ntawm vib nas this [s], teev, [h], lossis xyoo [yr]. Piv txwv li, 1 kWh [kilowatt teev] = 3.6 MJ [MegaJoule]. Nrog 1 kWh, txog 10 liv dej tuaj yeem ua kom sov los ntawm 20 ºC mus rau qhov kub kub.

Nyob rau hauv txoj kev no, dab tsi yog lwm qhov ua tau ntawm lub zog?

1 Joule (J) yog MKS unit ntawm lub zog , sib npaug rau lub zog ntawm ib tug Newton ua dhau ib 'meter'. 1 Watt yog lub zog los ntawm qhov tam sim no ntawm 1 Ampere ntws los ntawm 1 Volt. 1 kilowatt yog ib txhiab Watts. 1 kilowatt-teev yog qhov zog ntawm ib kilowatt zog ntws rau ib teev.

Tsis tas li ntawd, dab tsi yog ib chav tsev ntawm lub zog? Newton meter yog cov lus teb rau qhov no. Ib tug newton meter yog tsis yog ib chav tsev ntawm lub zog , theej, nws yog a chav tsev uas tuaj yeem pom hauv SI system. Lub joule kuj txawv ntawm qhov newton ' meter ' vim hais tias joule twb ib unit ntawm lub zog thaum Newton ' meter ' yog tsis yog.

Ib yam li ntawd ib tug yuav nug, dab tsi yog lub hauv paus rau lub zog?

Lub SI unit ntawm lub zog yog lub joule ua (J). Cov joule ua muaj cov units ntawm kg·m²/s² = N·m.

Qhov loj tshaj ntawm lub zog yog dab tsi?

Joule
