Gravitational Potential Zog vs Muaj Peev Xwm Zog
Lub zog muaj peev xwm thiab lub zog muaj peev xwm yog ob lub ntsiab lus tseem ceeb hauv kev siv tshuab thiab statics ntawm lub cev. Kab lus no piav qhia luv luv ntawm ob lub ntsiab lus ua ntej, thiab tom qab ntawd sib piv qhov zoo sib xws thiab qhov sib txawv ntawm lawv.
Dab tsi yog Gravitational Potential Zog?
Txhawm rau nkag siab lub zog muaj peev xwm ntawm lub zog, kev paub keeb kwm yav dhau los hauv thaj av gravitational yog xav tau. Lub ntiajteb txawj nqus yog lub zog uas tshwm sim vim muaj ib qho loj. Mass yog qhov tsim nyog thiab txaus rau lub ntiajteb txawj nqus. Muaj ib qho gravitational teb hais tias nyob ib ncig ntawm txhua qhov loj. Coj pawg neeg m1 thiab m2 tso rau hauv qhov deb r ntawm ib leeg. Lub zog gravitational ntawm ob pawg no yog G.m1m2 / r2, qhov twg G yog qhov universal gravitational tsis tu ncua. Txij li cov huab hwm coj tsis zoo tsis muaj nyob, lub zog gravitational yeej ib txwm nyiam. Tsis muaj zog gravitational quab yuam. Nws yuav tsum tau muab sau tseg tias gravitational rog kuj yog kev sib nrig sib. Qhov ntawd txhais tau hais tias lub zog m1 tawm ntawm m2 yog sib npaug thiab tawm tsam rau lub zog m2 yog exerting on m1 Lub peev xwm gravitational ntawm ib qho taw tes yog txhais raws li tus nqi ntawm kev ua haujlwm ntawm ib chav tsev loj thaum nqa nws los ntawm qhov tsis muaj qhov kawg mus rau qhov muab. Txij li thaum lub peev xwm gravitational ntawm infinity yog xoom thiab cov haujlwm yuav tsum tau ua yog qhov tsis zoo, lub peev xwm gravitational yeej ib txwm tsis zoo. Lub zog gravitational muaj peev xwm ntawm ib yam khoom yog txhais raws li kev ua haujlwm ntawm cov khoom thaum cov khoom raug coj los ntawm infinity mus rau qhov hais. Qhov no kuj yog sib npaug rau cov khoom ntawm lub peev xwm gravitational thiab qhov loj ntawm cov khoom. Txij li thaum qhov loj ntawm cov khoom yog ib txwm zoo thiab lub peev xwm gravitational ntawm ib qho twg yog qhov tsis zoo, lub zog gravitational ntawm txhua yam khoom kuj yog qhov tsis zoo.
Puas muaj zog yog dab tsi?
Muaj peev xwm lub zog ntawm ib qho khoom yog lub zog ntawm ib qho khoom vim qhov tso ntawm qhov khoom. Lub zog muaj peev xwm tuaj yeem muaj ntau hom. Gravitational muaj peev xwm zog yog lub zog muaj peev xwm ntawm ib yam khoom uas muaj huab hwm coj tau txais vim qhov kev tso ntawm qhov khoom. Hluav taws xob muaj peev xwm zog, uas tseem hu ua electrostatic muaj peev xwm zog, yog lub zog ntawm ib yam khoom uas muaj tus nqi uas nws tau ntsib vim qhov chaw. Lub zog muaj peev xwm sib nqus, uas tseem hu ua electrodynamic muaj peev xwm zog, yog lub zog uas tau ntsib los ntawm ib qho khoom uas muaj qhov sib nqus vim qhov chaw. Gravitational muaj peev xwm muaj peev xwm tsuas yog qhov tsis zoo. Muaj lwm yam kev muaj peev xwm ntawm lub zog xws li nuclear muaj peev xwm zog, tshuaj muaj peev xwm zog thiab elastic muaj peev xwm zog. Lub zog muaj peev xwm tuaj yeem tshwm sim vim muaj kev sib cuag nrog cov rog. Hom lub zog muaj peev xwm no tau ntsib hauv lub zog elastic zog. Feem ntau ntawm lwm qhov muaj peev xwm tshwm sim vim thaj chaw.
Dab tsi yog qhov txawv ntawm Lub Zog Muaj Peev Xwm thiab Lub Zog Muaj Peev Xwm Loj?
• Lub zog muaj peev xwm tsuas yog nyob ntawm qhov muaj peev xwm gravitational ntawm qhov taw tes thiab qhov loj ntawm cov khoom.
• Lub zog muaj peev xwm nyob ntawm ntau yam xws li kev them nqi, tam sim no, hluav taws xob muaj peev xwm thiab ntau lwm yam.
• Lub peev xwm gravitational tsuas yog coj qhov tsis zoo xwb, tab sis lub zog muaj peev xwm, feem ntau, tuaj yeem coj tus nqi.
