Muaj peev xwm zog yog khaws cia zog thiab cov zog ntawm txoj hauj lwm - gravitational zog . Muaj ob peb daim ntawv ntawm muaj peev xwm zog . Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Tshuaj Zog yog zog khaws cia rau hauv daim ntawv cog lus ntawm atoms thiab molecules.
Nyob rau hauv no, dab tsi hom ntawm lub zog yog kinetic?
Thaum koj tso lub pob ntawd thiab cia nws poob, lub peev xwm zog converts rau hauv kinetic zog , lub zog txuam nrog kev txav. Muaj tsib hom ntawm kinetic zog : radiant, thermal, suab, hluav taws xob thiab mechanical. Cia peb tshawb nrhiav ntau yam kinetic zog piv txwv los qhia txog ntau yam no zoo dua daim ntawv.
Tsis tas li ntawd, lub zog hluav taws xob puas yog ib hom ntawm lub zog kinetic? Hluav taws xob . Hluav taws xob yog tshwm sim los ntawm kev txav mus los hluav taws xob nqi hu ua electrons. Qhov ceev cov nqi txav, ntau dua hluav taws xob zog lawv nqa. Raws li cov nqi uas ua rau lub zog tab tom tsiv, hluav taws xob zog yog a daim ntawv ntawm kinetic zog.
Tom qab ntawd, lo lus nug yog, lub zog muaj peev xwm ua lub zog kinetic li cas?
Thaum ib yam khoom ntog, nws gravitational muaj peev xwm zog hloov rau kinetic zog . Koj tuaj yeem siv qhov kev sib raug zoo no los xam qhov ceev ntawm qhov khoom qhovntsej thiaj tsis mob. Gravitational muaj peev xwm zog rau qhov loj m ntawm qhov siab h ze ntawm qhov chaw ntawm lub ntiaj teb yog mgh ntau tshaj qhov muaj peev xwm zog yuav yog qhov siab 0.
Puas yog roj kinetic lossis lub zog muaj peev xwm?
Cov kinetic zog ntawm cov dej nrawm nrawm tig turbines, uas tsav cov tshuab hluav taws xob uas tsim hluav taws xob. Cov zog nyob rau hauv fossil fuels (coal, roj , gas) yog Chemical Muaj Peev Xwm Zog . Fossil fuels los ntawm cov khoom uas muaj sia nyob uas tau khaws cia zog nyob rau hauv nws cov chemical bonds (bonds ntawm atoms thiab molecules).

Cov piv txwv ntawm kinetic thiab lub zog muaj peev xwm yog dab tsi?
Muaj peev xwm Kinetic Zog Ib lub caij nplooj ntoos hlav coiled. Lub log ntawm cov menyuam skates ua ntej ib tug neeg skates. Ib tug archer hneev nrog txoj hlua rub rov qab. Ib qho hnyav hnyav. Cov dej uas nyob tom qab lub pas dej. Ib pob daus (muaj peev xwm avalanche) Lub quarterback caj npab ua ntej ntuav hla. Ib tug stretched roj hmab band
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Dab tsi yog qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog?
Tsis muaj qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog. Lub peev xwm hluav taws xob ntawm ib qho taw tes yog kev ua haujlwm los ntawm lwm qhov kev quab yuam hauv kev txav chav tsev zoo los ntawm ib qho arbitrarilychosen xoom ntawm lub peev xwm (feem ntau infinity) mus rau lub ntsiab lus
Dab tsi yog kev sib raug zoo ntawm gravitational muaj peev xwm zog thiab kinetic zog?
Thaum ib yam khoom ntog, nws lub peev xwm gravitational hloov mus rau kinetic zog. Koj tuaj yeem siv qhov kev sib raug zoo no los xam qhov ceev ntawm qhov khoom qhovntsej thiaj tsis mob. Gravitational muaj peev xwm zog rau ib pawg m ntawm qhov siab h nyob ze ntawm lub ntiaj teb yog mgh ntau tshaj li lub zog muaj peev xwm yuav nyob rau qhov siab 0
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
