Qhov siab dua ib yam khoom yog qhov ntau dua nws lub peev xwm gravitational zog . Raws li feem ntau ntawm GPE no tau hloov mus rau hauv kinetic zog , qhov siab dua qhov khoom pib ntawm qhov nrawm dua nws yuav poob thaum nws tsoo hauv av. Yog li kev hloov pauv hauv lub peev xwm gravitational zog nyob ntawm qhov qhov siab ib yam khoom txav mus los.
Dhau li ntawm no, vim li cas lub zog muaj peev xwm nce nrog qhov siab?
Muaj peev xwm zog yog qhov qhia tau tias tus nqi ntau npaum li cas kinetic zog ib qho khoom tuaj yeem nce hauv qab lub caij nplooj zeeg dawb los ntawm nws txoj haujlwm tam sim no. Yog li ntau qhov siab txhais tau hais tias cov khoom yuav muaj sij hawm poob ntau dua, thiab yuav nce nrawm dua vim yog lub ntiajteb txawj nqus. Thiab qhov nrawm dua txhais tau tias muaj ntau dua kinetic zog.
Ib tug kuj yuav nug, ua li cas koj nrhiav kinetic zog los ntawm qhov siab? Rau xam kinetic zog , sau a qauv qhov twg kinetic zog yog sib npaug rau 0.5 npaug loj lub sij hawm tshaj tawm squared. Ntxiv rau tus nqi rau qhov loj ntawm cov khoom, ces qhov tshaj tawm uas nws tsiv. daws rau qhov tsis paub sib txawv. Koj cov lus teb yuav tsum tau hais hauv joules, lossis J.
Tib neeg kuj nug, puas yog lub zog kinetic nce nrog huab hwm coj?
Kinetic zog yog cov zog ntawm pawg hauv kev tawm suab. Cov kinetic zog ntawm ib yam khoom yog qhov zog nws muaj vim nws txoj kev txav. Thaum peb muab ob npaug rau pawg , peb muab ob npaug rau zog ; Txawm li cas los xij, thaum peb muab ob npaug rau qhov nrawm, zog nce los ntawm ib qho ntawm plaub.
Puas yog lub zog kinetic nce nrog kev tshaj tawm?
Vim kinetic zog yog proportional rau cov ceev squared, nce hauv ceev yuav muaj kev cuam tshuam ntau dua rau kev txhais lus kinetic zog . Doubling qhov loj ntawm ib yam khoom yuav tsuas muab ob npaug rau nws kinetic zog , tab sis ob npaug rau ceev ntawm cov khoom yuav quadruple nws ceev.

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
