Kev nthuav qhia, 5 Hom Muaj Peev Xwm Muaj Zog . Muaj peev xwm zog yog khaws cia zog uas tuaj yeem hloov mus rau kinetic zog . Muaj ob peb daim ntawv muaj peev xwm zog suav nrog gravitational, sib nqus, hluav taws xob, tshuaj, thiab elastic muaj peev xwm zog.
Ib yam li ntawd, 6 hom muaj peev xwm muaj peev xwm yog dab tsi?
Cov ntau yam muaj peev xwm zog yog gravitational, elastic, tshuaj, hluav taws xob thiab nuclear.
Ib sab saum toj no, 4 hom muaj peev xwm muaj peev xwm yog dab tsi? Feem ntau hom muaj peev xwm zog suav nrog lub gravitational muaj peev xwm zog ntawm ib yam khoom uas nyob ntawm nws qhov hnyav thiab nws qhov deb ntawm qhov nruab nrab ntawm qhov loj ntawm lwm yam khoom, lub elastic muaj peev xwm zog ntawm lub caij nplooj ntoos hlav txuas ntxiv, thiab hluav taws xob muaj peev xwm zog ntawm ib qho hluav taws xob hauv hluav taws xob.
Kuj Paub, 5 piv txwv ntawm lub zog muaj peev xwm yog dab tsi?
Piv txwv ntawm Muaj Peev Xwm Muaj Peev Xwm
- Lub caij nplooj ntoos hlav coiled.
- Lub log ntawm cov menyuam skates ua ntej ib tug neeg skates.
- Ib tug archer hneev nrog txoj hlua rub rov qab.
- Ib qho hnyav hnyav.
- Cov dej uas nyob tom qab lub pas dej.
- Ib pob snow (muaj peev xwm avalanche)
- Ib lub quarterback caj npab ua ntej ntuav dhau.
- Ib tug stretched roj hmab band.
Dab tsi yog 3 hom muaj peev xwm zog?
Peb hom muaj peev xwm muaj peev xwm muaj xws li: Elastic muaj peev xwm zog , uas yog lub zog khaws cia rau hauv ib yam dab tsi thaum koj thawb, rub, los yog quab yuam nws tawm ntawm cov duab: xav txog cov roj hmab bands lossis springs. Tshuaj muaj peev xwm zog , uas yog lub zog ib yam dab tsi khw muag khoom vim nws tshuaj pleev: roj teeb muaj lub zog zoo li no.

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 kev sib raug zoo ntawm gravitational muaj peev xwm zog thiab kinetic zog?
Thaum ib yam khoom ntog, nws lub peev xwm gravitational hloov mus rau kinetic zog. Koj tuaj yeem siv qhov kev sib raug zoo no los xam qhov ceev ntawm qhov khoom qhovntsej thiaj tsis mob. Gravitational muaj peev xwm zog rau ib pawg m ntawm qhov siab h nyob ze ntawm lub ntiaj teb yog mgh ntau tshaj li lub zog muaj peev xwm yuav nyob rau qhov siab 0
Puas yog lub zog hauv daim ntawv ntawm kev txav yog lub zog muaj peev xwm?
Lub zog nyob rau hauv daim ntawv ntawm kev txav yog 'muaj peev xwm' zog. Qhov ntau dua 'mas' ib qho khoom txav muaj, lub zog kinetic nws muaj. Lub pob zeb ntawm ntug pob tsuas muaj 'kinetic' zog vim nws txoj hauj lwm. 'Thermal' zog yog lub zog khaws cia los ntawm cov khoom uas ncab los yog compression
Puas muaj peev xwm equilibrium zoo ib yam li so muaj peev xwm?
Qhov sib txawv ntawm daim nyias nyias muaj peev xwm thiab qhov muaj peev xwm sib npaug (-142 mV) sawv cev rau lub zog hluav taws xob hluav taws xob uas tsav Na + mus rau hauv lub xovtooj ntawm lub peev xwm so membrane. Thaum so, txawm li cas los xij, qhov permeability ntawm daim nyias nyias mus rau Na + tsawg heev kom tsuas yog me me Na + xau rau hauv lub cell
