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.
Tsis tas li ntawd, hluav taws xob muaj peev xwm yog dab tsi hauv cov lus yooj yim?
hluav taws xob muaj peev xwm . n. Kev ua haujlwm ntawm ib chav tsev yuav tsum tau txav tus nqi los ntawm qhov chaw siv mus rau qhov chaw tshwj xeeb, ntsuas hauv joules ib coulomb lossis volts. Thestatic hluav taws xob teb yog qhov tsis zoo ntawm gradient ntawm lub hluav taws xob muaj peev xwm.
Kuj Paub, qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog yog dab tsi? “ Muaj peev xwm "yog ib qho shorthand rau" hluav taws xob muaj peev xwm zog per unit nqi". Qhov sib txawv ntawm electrostatic muaj peev xwm ntawm ob lub ntsiab lus yog qhov voltage. Voltage yog tus nqi ntawm muaj peev xwm hloov rau 1 coulomb ntawm tus nqi txav los ntawm thawj point mus rau qhov thib ob.
Tsis tas li ntawd, koj txhais li cas los ntawm electrostatic?
Electrostatic phenomena tshwm sim los ntawm lub zog uas hluav taws xob tsub nqi rau ib leeg. Xws li lub zog yog tau piav los ntawm Coulomb txoj cai. Electrostatics koom nrog kev tsim cov nqi ntawm cov khoom siv vim kev sib cuag nrog lwm qhov chaw.
Tus qauv ntawm electrostatic muaj peev xwm zog yog dab tsi?
Zoo li txhua txoj haujlwm thiab zog , unit of muaj peev xwm zog yog Joule (J), qhov twg 1 J = 1kg∙m2/s2. Chav tsev ntawm tus nqi yog lub Coulomb (C), thiab chav tsev ntawm hluav taws xob muaj peev xwm yog Volt(V), uas yog sib npaug rau ib Joule per Coulomb (J/C).

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
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
