Txoj cai ntawm kev txuag ntawm zog hais tias rau txhua qhov system, zog tsis tuaj yeem tsim lossis rhuav tshem; nws tsuas tuaj yeem hloov ntawm ib daim ntawv mus rau lwm qhov lossis hloov los ntawm ib yam khoom mus rau lwm tus. Mechanical zog tuaj nyob rau hauv ob hom: muaj peev xwm zog , uas yog khaws cia zog , thiab kinetic zog , yog zog ntawm kev tawm suab.
Ib yam li ntawd, nws raug nug, koj tuaj yeem ua pov thawj li cas tias lub zog siv hluav taws xob txuag tau?
Yog tias tsuas yog cov tub rog sab hauv ua haujlwm (tsis muaj kev ua haujlwm los ntawm cov tub rog sab nraud), ces tsis muaj kev hloov pauv ntawm tag nrho cov nyiaj mechanical zog . Tag nrho mechanical zog yog hais tias yog khaws cia.
Ib qho tseem yuav nug, puas yog lub zog siv hluav taws xob txuag hauv lub pendulum? Hauv qhov yooj yim pendulum tsis muaj kev sib txhuam, mechanical zog yog khaws cia . Tag nrho mechanical zog yog kev sib koom ua ke kinetic zog thiab gravitational muaj peev xwm zog . Raws li cov pendulum swings rov qab thiab tawm, muaj kev sib pauv tsis tu ncua ntawm kinetic zog thiab gravitational muaj peev xwm zog.
Ua raws li qhov no hauv kev xav, puas yog lub zog siv hluav taws xob ib txwm khaws cia?
Kev piav qhia: Mechanical zog yog qhov suav ntawm kinetic thiab muaj peev xwm zog hauv ib qhov system. Mechanical zog yog khaws cia tsuav yog peb tsis quav ntsej tej huab cua, kev sib txhuam, thiab lwm yam. Thaum peb tsis quav ntsej txog sab nraud, xws li cov uas nyuam qhuav hais, mechanical zog tsis yog khaws cia.
Lub zog pauv thiab txuag tau li cas?
Kev txuag ntawm Zog & Hloov zog . Ib qho tseem ceeb heev thiab muaj txiaj ntsig qhov tseeb txog zog yog tias nws tuaj yeem hloov ntawm ib daim ntawv mus rau lwm qhov. Thaum lub tshuab ua haujlwm zog tsis siv li nws yog pauv – hloov los ntawm ib daim ntawv mus rau lwm qhov. Tus nqi ntawm zog nyob li qub los yog hais tias yog khaws cia.

Txoj cai lij choj ntawm kev txuag hluav taws xob siv li cas rau kev hloov hluav taws xob?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias lub zog tsis tuaj yeem tsim lossis rhuav tshem - tsuas yog hloov los ntawm ib hom ntawm lub zog mus rau lwm qhov. Qhov no txhais tau hais tias ib qho system ib txwm muaj tib lub zog, tshwj tsis yog nws ntxiv los ntawm sab nraud. Tib txoj kev siv lub zog yog hloov lub zog ntawm ib daim ntawv mus rau lwm qhov
Lub zog hluav taws xob hloov hluav taws xob li cas?
Tab sis yuav ua li cas qhov no ua hauj lwm nyob rau hauv cov nqe lus ntawm circuits? Qhov hluav taws xob muaj peev xwm hloov pauv mus rau lub zog hluav taws xob li niaj zaus thaum cov hluav taws xob txav mus los ntawm lub voj voog. Tom qab ntawd, lub zog hluav taws xob tau xa mus rau cov khoom hauv Circuit Court. Yog hais tias lub voj voog muaj lub teeb, nws tawm los ua lub teeb lub zog thiab lub zog hluav taws xob tsis zoo
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
