Ib Cov khoom muaj peev xwm muaj ob qho tib si kinetic thiab muaj peev xwm zog tib lub sijhawm. Piv txwv li, ib khoom uas yog ntog, tab sis tseem tsis tau mus txog hauv av muaj kinetic zog vim nws txav mus deb, thiab muaj peev xwm zog vim tias nws muaj peev xwm txav mus rau qhov chaw qis dua qhov nws twb muaj lawm.
Ua raws li qhov xav tau, vim li cas cov khoom muaj ob qho tib si kinetic thiab lub zog muaj peev xwm?
Cov khoom ntawm cov khoom muaj kinetic thiab muaj peev xwm zog vim cov zog no yog tsav los ntawm lub zog ntawm kev txav los yog qhov tseem ceeb ntawm ib qho khoom. Kinetic zog ntawm qhov tod tes, yog tus zog nyob rau hauv kev txav los yog yog tias cov khoom txav los ntawm ib qho chaw mus rau lwm qhov nrog rau lub sijhawm.
Kuj Paub, ib yam khoom puas muaj lub zog kinetic tab sis tsis muaj lub zog muaj peev xwm muab piv txwv? Ib piv txwv ntawm ib khoom uas nkaus xwb muaj kinetic zog yuav yog ib tug photon, nyob rau hauv mechanics, yog. Los ntawm txhais, lub = zero oif muaj peev xwm zog yog arbitrary. Ib khoom uas muaj swb mus rau hauv qab ntawm lub toj yuav muaj xoom gravitational muaj peev xwm zog thiab tsis yog -zero kinetic zog.
Ib tug kuj yuav nug, hom zog twg yog ob qho tib si muaj peev xwm thiab kinetic?
mechanical zog
Puas yog txhua yam khoom muaj peev xwm muaj zog?
Kinetic thiab peev xwm muaj zog muaj nyob rau hauv txhua yam khoom . Yog ib khoom yog tsiv, nws hais rau muaj kinetic zog (KE). Muaj peev xwm zog (PE) yog zog uas yog "kho" vim yog txoj haujlwm thiab / lossis kev npaj ntawm cov khoom . Thiab hauv kev poob, tuaj yeem tawm dag zog thiab ua ua hauj lwm rau lwm tus khoom.

Cov piv txwv ntawm kinetic thiab lub zog muaj peev xwm yog dab tsi?
Muaj peev xwm Kinetic Zog Ib lub caij nplooj ntoos hlav coiled. Lub log ntawm cov menyuam skates ua ntej ib tug neeg skates. Ib tug archer hneev nrog txoj hlua rub rov qab. Ib qho hnyav hnyav. Cov dej uas nyob tom qab lub pas dej. Ib pob daus (muaj peev xwm avalanche) Lub quarterback caj npab ua ntej ntuav hla. Ib tug stretched roj hmab band
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
