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.
