Muaj peev xwm zog yog zog uas yog khaws cia rau hauv ib yam khoom. Piv txwv li, ib tug roj hmab band uas yog stretched muaj elastic muaj peev xwm zog , vim hais tias thaum tso tawm, cov roj hmab band yuav rov qab mus rau nws lub xeev so, hloov lub muaj peev xwm zog rau kinetic zog nyob rau hauv tus txheej txheem.
Yog li ntawd, puas muaj peev xwm elastic sib npaug rau lub zog gravitational?
Gravitational muaj peev xwm zog nyob ntawm ib qho khoom hnyav thiab nws qhov siab tshaj hauv av (GPE = qhov hnyav x qhov siab). Elastic muaj peev xwm zog yog vim ib yam khoom lub cev. Nws tshwm sim thaum ib elastic khoom yog stretched los yog compressed. Qhov ntau nws yog stretched los yog compressed, ntau dua nws elastic muaj peev xwm zog yog.
Tom qab, lo lus nug yog, dab tsi yog cov units rau elastic muaj peev xwm zog? elastic muaj peev xwm zog (E e) yog ntsuas hauv joules ua (J) lub caij nplooj ntoos hlav tsis tu ncua (k) yog ntsuas hauv newtons ib 'meter' ( N/m )
Yog li ntawd, lub zog elastic muaj peev xwm sib npaug li cas?
Elastic muaj peev xwm zog yog Muaj peev xwm zog khaws cia raws li qhov tshwm sim ntawm deformation ntawm ib qho elastic khoom, xws li stretching ntawm lub caij nplooj ntoos hlav. Nws yog sib npaug txoj hauj lwm ua kom ncav lub caij nplooj ntoos hlav, uas nyob ntawm lub caij nplooj ntoos hlav tas li k raws li qhov kev ncua deb.
Qhov piv txwv ntawm lub zog muaj peev xwm yog dab tsi?
Ib yam khoom tuaj yeem khaws cia zog raws li qhov tshwm sim ntawm nws txoj haujlwm. Rau piv txwv , lub pob hnyav ntawm lub tshuab demolition yog khaws cia zog thaum nws tuav ntawm qhov chaw siab. Qhov no khaws cia zog ntawm txoj hauj lwm yog hu ua muaj peev xwm zog.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
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 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
