Lub SI unit ntawm lub zog yog lub joule ua , uas yog lub zog pauv mus rau ib qho khoom los ntawm kev ua haujlwm ntawm kev txav mus deb ntawm 1 meter tiv thaiv lub zog ntawm 1 newton.
Cov ntawv.

Raws li, dab tsi yog lub ntsiab units ntawm lub zog?
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)
Ib yam li ntawd, lub zog ntsuas nyob rau hauv dab tsi? 1 Joule (J) yog MKS unit 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.
Hais txog qhov no, dab tsi yog lub zog hauv biology?
Zog yog cov khoom ntawm cov khoom uas tuaj yeem hloov mus rau lwm yam khoom lossis hloov mus rau ntau hom, tab sis tsis tuaj yeem tsim lossis rhuav tshem. Lub cev siv zog kom ciaj sia, loj hlob, teb rau stimuli, reproduce, thiab rau txhua yam ntawm lom txheej txheem.
Dab tsi yog qhov zoo tshaj plaws txhais ntawm lub zog?
Zog . Feem ntau txhais lub zog yog ib txoj hauj lwm uas muaj zog (gravitational, electromagnetic, thiab lwm yam) ua tau. Vim muaj ntau lub zog, zog muaj ntau yam sib txawv (gravitational, hluav taws xob, tshav kub, thiab lwm yam) uas tuaj yeem muab faib ua ob pawg loj: kinetic zog thiab muaj peev xwm zog.

Dab tsi yog chav tsev siv rau lub voj voog ncig?
Txhawm rau nrhiav qhov ncig ntawm lub voj voog, coj nws qhov ntev lub sij hawm pi, uas yog 3.14. Piv txwv li, yog hais tias lub cheeb ntawm lub voj voog yog 10 centimeters, ces nws ncig yog 31.4 centimeters. Yog tias koj tsuas paub lub vojvoog, uas yog ib nrab ntawm txoj kab uas hla, koj tuaj yeem nqa lub vojvoog lub sijhawm 2 pi, lossis 6.28
Dab tsi yog ib chav tsev ntawm lub zog?
Newton meter yog cov lus teb rau qhov no. Ib lub ntsuas hluav taws xob tshiab tsis yog ib chav tsev ntawm lub zog, tab sis, nws yog ib 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
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
