Zog tsis tuaj yeem tsim los tsis tuaj yeem rhuav tshem. Muaj peev xwm zog yog cov zog nyob rau hauv lub cev vim nws txoj hauj lwm. Thaum kinetic zog yog cov zog nyob rau hauv lub cev vim nws txoj kev txav. Cov mis rau muaj peev xwm zog yog mgh, qhov twg m stands rau mass, g stands rau gravitational acceleration thiab h stands rau qhov siab.
Nyob rau hauv no hais txog, hom zog twg muaj peev xwm thiab kinetic?
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.
Tsis tas li ntawd, qhov txawv ntawm lub zog kinetic thiab lub zog muaj peev xwm yog dab tsi? Qhov sib txawv ntawm Kinetic Zog thiab Muaj Peev Xwm Muaj Peev Xwm . Zog implies raws li qhov khoom muaj peev xwm ua haujlwm. Thaum kinetic zog yog cov zog uas ib yam khoom muaj vim yog ib qho kev txav. Ntawm qhov tod tes, muaj peev xwm zog yog khaws cia zog , vim nws lub xeev ntawm so.
Ntxiv mus, qhov kev sib raug zoo ntawm lub zog muaj zog thiab lub zog kinetic yog dab tsi?
Cov Kev sib raug zoo ntawm Kinetic thiab Muaj Peev Xwm Zog . Peb paub tias muaj peev xwm zog yog cov zog uas yog khaws cia rau hauv ib yam khoom thaum kinetic zog yog cov zog uas yog nyob rau hauv tsab ntawv tsa suab. Cov kev sib txuas ntawm ob yog li ntawd muaj peev xwm zog transforms rau hauv kinetic zog.
Lub zog zoo li cas hauv lub roj teeb muaj peev xwm lossis lub zog kinetic?
Piv txwv li, khaws cia tshuaj muaj peev xwm zog ntawm a roj teeb converts rau hluav taws xob kinetic zog mus thauj hluav taws xob mus rau lub teeb, uas radiates thermal kinetic zog.

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
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
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
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
