Hluav taws xob muaj peev xwm Nws tsuas yog ua haujlwm ua haujlwm rau ib chav xwb kom txav mus los ntawm ib qho peev xwm rau lwm tus peev xwm nyob rau hauv lub hluav taws xob teb . Qhov sib txawv ntawm ob qhov sib txawv equipotentials yog qhov peev xwm qhov txawv los yog qhov sib txawv voltage. Hluav taws xob teb piav txog lub zog ntawm tus nqi.
Yog li ntawd, qhov kev sib raug zoo ntawm hluav taws xob muaj peev xwm thiab hluav taws xob teb yog dab tsi?
Cov kev sib raug zoo ntawm lub peev xwm thiab teb ( E ) yog qhov sib txawv: hluav taws xob teb yog gradient peev xwm (V) x direction. Qhov no tuaj yeem sawv cev raws li: E x=-dVdx E x = − dV dx. Yog li, raws li qhov kev ntsuas tus nqi raug txav mus rau hauv x kev taw qhia, tus nqi ntawm nws qhov kev hloov pauv hauv peev xwm yog tus nqi ntawm cov hluav taws xob teb.
Kuj Paub, kev ua haujlwm cuam tshuam li cas rau hluav taws xob muaj peev xwm? Thaum twg ua haujlwm yog ua tiav ntawm qhov kev kuaj pom zoo kom txav nws ntawm ib qho chaw mus rau lwm qhov, peev xwm zog nce thiab hluav taws xob muaj peev xwm nce. Tus nqi kuaj pom zoo yog qhia ntawm point A. Rau txhua daim duab, qhia seb puas yog ua haujlwm yuav tsum tau ua raws li tus nqi kom txav los ntawm point A mus rau point B.
Ntawm no, hluav taws xob muaj peev xwm cuam tshuam li cas rau hluav taws xob muaj peev xwm?
Hluav taws xob muaj peev xwm zog Ue yog muaj peev xwm zog khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li gravitational muaj peev xwm zog ). Hluav taws xob muaj peev xwm yog tib yam, tab sis ib tus nqi, Ueq. Ib hluav taws xob muaj peev xwm Qhov sib txawv ntawm ob lub ntsiab lus yog hu ua voltage, V = Ue2q−Ue1q.
Tus qauv ntawm hluav taws xob teb yog dab tsi?
qhov loj ntawm qhov hluav taws xob (E) tsim los ntawm ib qho taw tes nqi nrog a nqi ntawm qhov loj Q, ntawm qhov chaw nyob deb r deb ntawm qhov taw tes nqi , yog muab los ntawm kab zauv E = kQ/r2, qhov twg k yog qhov tsis tu ncua nrog tus nqi ntawm 8.99 x 109 N m2/C2.

Lub peev xwm thiab lub zog kinetic cuam tshuam li cas rau cov menyuam coasters?
Hauv lwm lo lus, tag nrho cov nyiaj ntawm lub zog tseem nyob tas li. Ntawm cov menyuam coaster, lub zog hloov pauv ntawm lub peev xwm mus rau lub zog kinetic thiab rov qab ntau zaus thaum caij tsheb. Kinetic zog yog lub zog uas ib yam khoom muaj los ntawm nws txoj kev txav. Lub zog muaj peev xwm yog khaws cia lub zog uas tseem tsis tau tso tawm
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
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
