Muaj peev xwm zog yog zog khaws cia rau hauv ib yam khoom vim nws txoj hauj lwm los yog kev npaj. Kinetic zog yog zog ntawm ib yam khoom vim nws txav - nws cov lus tsa suab. Txhua yam ntawm zog tuaj yeem hloov mus rau lwm hom zog.
Hauv qhov no, kinetic thiab lub zog muaj peev xwm yog dab tsi?
Zog tsis tuaj yeem tsim los tsis tuaj yeem rhuav tshem. Muaj peev xwm zog yog cov zog nyob rau hauv ib 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 sawv rau qhov loj, g sawv rau gravitational acceleration thiab h sawv rau qhov siab.
Ib tug kuj yuav nug, kinetic zog physics yog dab tsi? Hauv physics , cov kinetic zog (KE) ntawm qhov khoom yog qhov zog uas nws muaj vim nws txoj kev txav. Nws txhais tau hais tias yog txoj haujlwm xav tau los ua kom lub cev ntawm ib qho khoom loj los ntawm so mus rau nws qhov kev tshaj tawm. Tau txais qhov no zog thaum nws acceleration, lub cev tswj qhov no kinetic zog tshwj tsis yog nws qhov nrawm hloov.
Ua raws li qhov no hauv kev xav, dab tsi yog lub zog kinetic thiab lub zog muaj peev xwm nrog piv txwv?
Kinetic zog yog txuam nrog ib yam khoom nrog ib tug loj txav ntawm ib tug ceev thaum muaj peev xwm zog yog txuam nrog ib qho khoom nyob ruaj ruaj nrog ib qho loj ntawm qhov siab tshaj hauv av. Ib piv txwv ntawm ib yam khoom nrog kinetic zog yuav yog ib lub tsheb tsav raws txoj kev loj ntawm 100km/h.
Puas muaj peev xwm thiab lub zog kinetic tib yam?
Muaj Peev Xwm Zog yog khaws cia zog nyob rau hauv ib yam khoom los yog system vim nws txoj hauj lwm los yog configuration. 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. Kinetic zog tuaj yeem hloov los ntawm ib qho khoom txav mus rau lwm qhov, hais, hauv kev sib tsoo.

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
