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.
