Qhov tsis yog Qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog . Cov hluav taws xob muaj peev xwm ntawm ib lub ntsiab lus yog kev ua hauj lwm ua los ntawm anexternal quab yuam nyob rau hauv tsiv unit zoo nqi los ntawm ib tug arbitrarilychosen xoom ntawm peev xwm (feem ntau infinity) mus rau qhov point.
Ua li no, txhais li cas los ntawm electrostatic peev xwm?
Ib hluav taws xob muaj peev xwm (tseem hu ua hluav taws xob teb peev xwm , peev xwm poob orth muaj peev xwm electrostatic ) yog tus nqi ntawm kev ua haujlwm uas yuav tsum tau txav mus rau ib chav tsev ntawm tus nqi los ntawm qhov chaw siv mus rau ib qho chaw tshwj xeeb hauv thaj teb yam tsis tau ua kom nrawm.
Ib yam li ntawd, koj txhais li cas los ntawm hluav taws xob muaj peev xwm? Hluav taws xob muaj peev xwm zog , los yog electrostaticpotential zog , yog a muaj peev xwm zog (ntsuas injoules) uas tshwm sim los ntawm kev saib xyuas Coulomb rog thiab koom nrog kev teeb tsa ntawm ib qho tshwj xeeb ntawm cov ntsiab lus hauv ib qho kev teev tseg.
Xav txog qhov no, qhov txawv ntawm hluav taws xob muaj peev xwm thiab hluav taws xob muaj peev xwm hluav taws xob yog dab tsi?
Hluav taws xob muaj peev xwm zog Ue yog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (likegravitational muaj peev xwm zog ). Hluav taws xob muaj peev xwm yog tib yam, tab sis ib tus nqi, Ueq. (Piv tau thaum sib piv txawv cov ntsiab lus.)
Unit ntawm peev xwm yog dab tsi?
Tus qauv metric chav tsev ntawm hluav taws xob peev xwm Qhov txawv yog qhov volt, luv luv V thiab lub npe hu ua inhonor ntawm Alessandro Volta. Ib Volt yog sib npaug rau ib Joule perCoulomb. Vim hluav taws xob peev xwm qhov txawv yog qhia units ntawm volts, nws yog qee zaum hu ua thevoltage.

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 qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
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
