Cov ntsiab lus ntawm zog thiab zog zoo li hais tau cov ntsiab lus zoo sib xws thiab feem ntau tsis meej pem rau ib leeg. Butin physics, lawv tsis hloov pauv. quab yuam yog qhov tseem ceeb ntawm kev sib cuam tshuam nruab nrab ob yam khoom, thaum zog yog ib qho kev qhia ntawm zog siv sijhawm dhau sijhawm ( ua haujlwm ), uas zog yog anelement.

Qhov yooj yim li ntawd, kev ua haujlwm quab yuam thiab lub zog cuam tshuam li cas?

Lub zog yog lub peev xwm ua tau ua haujlwm thiab ua haujlwm hloov lub zog ntawm cov khoom. Yog vim li cas ob leeg ua haujlwm andenergy yog ntsuas hauv Joules. Yuav ua li cas ua haujlwm Kuv thov ib zog (sib npaug rau qhov hnyav ntawm phau ntawv) mus rau phau ntawv hauv pem teb mus rau lub rooj. Ua haujlwm sib npaug zog timesthe nrug, nyob rau hauv units ntawm Newtons zaus Meters.

Tsis tas li ntawd, lub zog thiab kev ua haujlwm yog dab tsi? Hwj chim yog cov ua haujlwm ua nyob rau hauv ib chav tsev ntawm lub sij hawm. Ib lo lus, zog yog ib qho kev ntsuas sai npaum li cas ua haujlwm ua tau. Unit ntawm zog yog Watt = 1Joule/1 second. Ib chav tsev ntawm lub zog yog kilowatt-teev (kWh).

Ntawm no, kev ua haujlwm thiab lub zog zoo sib xws thiab txawv li cas?

Lawv yog zoo sib xws nyob rau hauv lub siab tias lawv muaj feem rau zog tab sis lawv yog txawv vim zog ntsuas tus nqi ntawm ua haujlwm ua tiav. Lawv kuj muaj txawv units, cov ua haujlwm yog joule thaum uas zog iswatt ua.

Qhov txawv ntawm lub zog thiab lub zog yog dab tsi?

" quab yuam ", hauv physics, yog ib qho kev cuam tshuam uas hloov cov khoom nrawm los yog cov duab. sib zog ob tug electrons. " Lub zog " hauv physics yog qhov ntau ntawm a zog : nws magnitude. Koj tuaj yeem muaj zog zog (ntau heev zog ) los yog qaug zog zog (tseem tsawg heev zog ?).
