Hwj chim sib npaug ua haujlwm (J) faib los ntawm lub sijhawm (s). SIunit rau zog yog watt (W), uas sib npaug 1 joule ntawm tus neeg ua haujlwm thib ob (J / s). Hwj chim tuaj yeem ntsuas hauv ib chav hu ua thehorsepower. Ib lub zog horsepower yog tus nqi ntawm kev ua haujlwm ib tus nees tuaj yeem ua hauv 1 feeb, uas sib npaug 745 watts ntawm zog.

Nyob rau hauv no hais txog, dab tsi yog lub mis rau kev daws hwj chim?

Ohm txoj cai kev sib npaug ( qauv ): V = I × R zog txoj cai kev sib npaug ( qauv ): P = I × V. P = zog , Kuv los yog J = Latin: influare, thoob ntiaj teb ampere, los yog siv thiab R = tsis kam. V = voltage, hluav taws xob muaj peev xwm sib txawv Δ V orE = electromotive force (emf = voltage).

Ib sab saum toj no, tus qauv rau kev ua haujlwm thiab lub zog yog dab tsi? Cov ua haujlwm yog xam los ntawm kev muab tus quab yuam los ntawm tus nqi ntawm kev txav ntawm ib qho khoom (W = F * d). Lub zog ntawm 10newtons, uas txav ib yam khoom 3 meters, ua 30 n-m ntawm ua haujlwm . A newton-meter yog tib yam li ib tug joule, yog li cov units rau ua haujlwm yog tib yam li cov rau zog -joules.

Tom qab ntawd, koj yuav suav li cas lub zog tso zis?

Muab quab yuam los ntawm kev ncua thiab faib sijhawm. Seb nyob rau hauv lub metric system los yog lus Askiv system, thaum koj tau sau cov ntaub ntawv rau lub zog, qhov deb thiab lub sij hawm, thov lawv mus rau lub qauv nrhiav tus neeg kho tshuab zog . Hwj chim = 150 lb.

Koj xam lub hwj chim li cas?

Ua lej, nws suav nrog cov lej hauv qab no. Tus qauv metric unit ntawm zog yog Watt. Asis implied los ntawm qhov sib npaug rau zog , ib unit zog yog sib npaug rau ib chav tsev ntawm kev ua hauj lwm muab faib los ntawm ib chav tsev ntawm lub sij hawm. Yog li, aWatt sib npaug rau ib Joule / thib ob.
