Zog tuaj yeem pom muaj ntau yam thiab siv ntau hom. Muaj lub zog muaj peev xwm nyob rau hauv cov khoom thaum so uas yuav ua rau lawv txav mus yog tias tsis kam raug tshem tawm. Muaj lub zog kinetic hauv cov khoom uas txav mus.
Cov khoom puas muaj zog?
Cov khoom tuaj yeem muaj lub zog kinetic thiab lub zog muaj peev xwm tib lub sijhawm. Ib yam khoom tuaj yeem nce siab saum av (muaj lub zog muaj peev xwm) thiab txav mus rau tib lub sijhawm (thiab kuj muaj lub zog kinetic).
Puas khoom nce lossis poob zog?
Feem ntau, yam khoom tsis tau txais lub zog muaj peev xwm, lawv tau txais lub zog kinetic thiab poob qhov sib npaug ntawm lub zog muaj peev xwm thaum nkag mus rau thaj chaw. Lub zog muaj peev xwm yog lub zog tuaj yeem pom raws li lub zog siv nyob rau qee lub sijhawm ua ntej kom tau txais cov khoom tawm sab nraud. Hauv tag nrho lub zog tshuav yog xoom.
Ib yam khoom raug them li cas?
Ib yam khoom tau them thaum nws rubbed. Qhov kev txhuam no ua rau cov khoom nce lossis poob electrons. Thaum nws poob electrons nws yuav zoo them. Thaum ib yam khoom tau txais electrons nws yuav tsis zoo.
Tus khoom nce nqi li cas?
Ib qho hluav taws xob raug tsim thaum hluav taws xob raug xa mus rau lossis tshem tawm ntawm ib qho khoom. Vim tias cov hluav taws xob muaj qhov tsis zoo, thaum lawv ntxiv rau ib qho khoom, nws yuav raug nqi tsis zoo. Thaum cov electrons raug tshem tawm ntawm ib qho khoom, nws yuav raug nqi zoo.

Cov neeg muag khoom puas yuav lav ris rau cov nyiaj tau txais dhau sijhawm?
Thib ob, tus neeg muag khoom puas yuav tsum muaj lub luag haujlwm los sau cov nyiaj tau los? Feem ntau hais lus, tsis muaj. Lub tuam tsev qiv nyiaj lossis lub tuam txhab nyiaj tau txais yuav tsum ua haujlwm feem ntau ntawm txoj haujlwm no. Txawm li cas los xij, muaj cov xwm txheej uas koj tau muag thiab xa nyiaj rau ib tus as khauj, thiab tam sim no nws qeeb hauv kev them nyiaj.
Thaum lub sijhawm tau txais cov khoom muaj sia nyob ntev tau sau tseg ntawm?
Tau txais cov khoom muaj nqis ntev. Thaum tau txais, cov khoom muaj nqis mus sij hawm ntev xws li cov cuab yeej, cov nroj tsuag, thiab cov cuab yeej raug kaw rau ntawm daim ntawv tshuav nyiaj li cas ntawm tus nqi, uas yog tib yam li tus nqi ncaj ncees.
Puas yog cov neeg siv khoom tau txais lub zog raws li kev lag luam nthuav dav?
Koj puas xav tias cov neeg siv khoom tau txais lub zog raws li kev lag luam nthuav dav hauv lig 19th caug xyoo? Yog lawm, kuv xav tias kev siv zog tau txais txiaj ntsig raws li kev lag luam tau nthuav dav hauv lub xyoo pua 19th, vim tias cov khoom siv tom qab ntawd muaj ntau yam kev tsim kho tshiab los xaiv.
Tib neeg puas tau txais lub zog ncaj qha los ntawm lub hnub?
Vim tib neeg noj cov kab mob uas ncaj qha lossis tsis ncaj tau txais lawv lub zog los ntawm lub hnub, yog peb muaj ib feem ntawm lub zog ntawm lub hnub. Lub zog ntawm lub hnub xa mus rau lub ntiaj teb los ntawm "thermal radiation."
Vim li cas cov khoom siv viav vias hu ua cov khoom sib sib zog nqus?
Ib tug viav vias tivthaiv yog hais tias yog ib tug sib sib zog nqus Cheebtsam vim nws sau tag nrho nyob rau hauv Java thiab ua cov theem siab zaub ua hauj lwm nws tus kheej, es tsis txhob cia siab rau cov code muab los ntawm koj lub computer.
