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. Ib tug newton meter yuav ntsuas txhua hom quab yuam. Ib qho Newton, ntawm qhov tod tes, yog qhov khoom ntawm qhov deb.
Tsis tas li ntawd, lub zog ntawm lub zog hu ua dab tsi?
Vim zog txhais los ntawm kev ua haujlwm, SI unit ntawm lub zog yog tib yam li cov chav tsev ntawm kev ua haujlwm - joule (J), npe nyob rau hauv kev hwm ntawm James Prescott Joule thiab nws cov kev sim ntawm qhov sib npaug ntawm cov cua sov. Hauv cov ntsiab lus tseem ceeb me ntsis, 1 joule yog sib npaug rau 1 newton meter thiab, nyob rau hauv cov nqe lus ntawm SI puag units.
Ib tug kuj yuav nug, yog Watt Ib chav tsev ntawm lub zog? Watts yog chav tsev ntawm POWER, uas yog tus nqi ntawm qhov twg ENERGY yog siv/tsim ib ob. Hauv MKS system nws Joules/Sec yog Watt . Thaum lub hwj chim no hloov mus rau lwm yam ntaub ntawv ntawm zog - tus units hloov. Watts yog chav tsev ntawm POWER, uas yog tus nqi ntawm qhov twg ENERGY yog siv/tsim ib ob.
Hais txog qhov no, plaub units ntawm lub zog yog dab tsi?
units ntawm lub zog yog joule ua , dyne, unit lossis kilowatt teev, horsepower..
Peb lub zog ntau npaum li cas?
Cov chav nyob ntawm lub zog thiab lub zog uas peb siv hauv lub neej niaj hnub tau teev tseg
- Cov roj. Barrel yog ib chav ntsuas ntawm qhov ntim.
- Calorie.
- Lub zog nees.
- Yog (J)
- Kilowat-hour (kWh)
- Kilowatt (kW)
- Megajoule (MJ)
- Megawatt (MW)

Dab tsi yog chav tsev ntawm lub zog siv hauv biology?
Lub SI chav tsev ntawm lub zog yog joule, uas yog lub zog hloov mus rau ib qho khoom los ntawm kev ua haujlwm ntawm kev txav mus deb ntawm 1 meter tawm tsam lub zog ntawm 1 newton. Cov ntawv. Hom ntawm lub zog Description So lub zog muaj peev xwm vim yog ib qho khoom so loj
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
