Thaum ib yam khoom ntog, nws gravitational muaj peev xwm zog hloov rau kinetic zog . Koj tuaj yeem siv qhov no kev sib raug zoo 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.
Kuj paub, qhov kev sib raug zoo ntawm lub zog muaj zog thiab lub zog kinetic yog dab tsi?
Muaj peev xwm zog yog cov zog muaj los ntawm lub cev los ntawm kev tsim txiaj ntawm nws txoj haujlwm lossis lub xeev. Kinetic zog yog zog muaj los ntawm lub cev los ntawm kev tsim txiaj ntawm nws lub zog. Txoj cai ntawm kev txuag ntawm zog hais tias zog tsis tuaj yeem rhuav tshem tab sis tsuas yog hloov tau ib daim ntawv mus rau lwm qhov.
Ib yam li ntawd, lub pendulum qhia txog kev sib raug zoo ntawm lub zog muaj zog thiab lub zog kinetic li cas? Hauv qhov yooj yim pendulum tsis muaj kev sib txhuam, mechanical zog yog khaws cia. Tag nrho cov tshuab zog yog kev sib koom ua ke ntawm kinetic zog thiab gravitational muaj peev xwm zog . Raws li cov pendulum swings rov qab thiab tawm, muaj kev sib pauv tas li nruab nrab ntawm lub zog kinetic thiab gravitational muaj peev xwm zog.
Tsis tas li ntawd, puas yog lub zog gravitational zoo ib yam li lub zog kinetic?
Nws yog ua tau los hloov zog ntawm ib daim ntawv mus rau lwm qhov. Gravitational muaj peev xwm zog (GPE) yog txuam nrog ib yam khoom loj thiab nws txoj hauj lwm. Nws yog sib npaug rau kev ua hauj lwm ib tug yuav tsum ua kom nqa ib yam khoom nyob ib ncig ntawm ib tug gravitational zog. Nws GPE hloov dua siab tshiab rau hauv kinetic zog.
Lub peev xwm thiab lub zog kinetic piv txwv yog dab tsi?
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.

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
Puas yog lub zog gravitational zoo ib yam li lub zog muaj peev xwm?
Lub zog muaj peev xwm yog lub zog uas khaws cia rau hauv ib yam khoom lossis khoom siv. Gravitational muaj peev xwm zog yog lub zog nyob rau hauv ib yam khoom uas yog tuav nyob rau hauv ib tug ntsug txoj hauj lwm. Elastic muaj peev xwm lub zog yog lub zog khaws cia hauv cov khoom uas tuaj yeem ncab lossis compressed
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 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
