Kev quab yuam uas tsis khaws lub zog yog hu ua nonconservative los yog dissipative rog . Kev sib txhuam yog anonconservative zog , thiab muaj lwm yam. Ib qho kev sib txhuam - hom zog , zoo li huab cua tsis kam, yog anonconservative zog . Lub zog uas nws tshem tawm los ntawm lub system yog tsis muaj nyob rau hauv lub system rau kineticenergy.
Raws li qhov tshwm sim, lub zog dissipative yog dab tsi?
Dissipative rog yog zog ntawm xws li hais tias lub zog poob los ntawm ib qho system thaum lub zog tshwm sim.
Tsis tas li ntawd, kev sib txhuam puas yog qhov tsis muaj zog? Lub gravitational zog , caij nplooj ntoos hlav zog , sib nqus zog (raws li qee qhov kev txhais, saib hauv qab) thiab hluav taws xob zog (tsawg kawg nyob rau hauv ib lub sij hawm-yooj yim magneticfield, saib Faraday txoj cai ntawm induction kom paub meej) yog cov piv txwv ntawm conservative zog , thaum kev sib txhuam thiab huab cua luag yog classical piv txwv ntawm tsis yog -conservative
Tom qab ntawd, lo lus nug yog, kev sib txhuam yog qhov tsis muaj zog li cas?
A zog yog hais tias yog tsis yog - kev saib xyuas thaum ua hauj lwm tawm tsam nws yog tsis yog conserved los ntawm lub cev uas yog txav los ntawm lub zog . Ib qho piv txwv ntawm tsis yog - kev saib xyuas hom ntawm zog yog kev sib txhuam quab yuam . Thaum lub cev tawm tsam kev sib txhuam , kev ua haujlwm yuav tsum tau kov yeej kev sib txhuam.
Lub ntiajteb txawj nqus puas yog kev sib txhuam?
Kev sib txhuam yog qhov kev tawm tsam ntawm ib qho khoom txav mus rau lwm qhov. Nws tsis yog ib qho tseem ceeb zog , zoo li lub ntiajteb txawj nqus los yog electromagnetism. Hloov chaw, cov kws tshawb fawb ntseeg tias nws yog qhov tshwm sim ntawm electromagneticattraction ntawm cov khoom siv hluav taws xob hauv ob qhov kev sib chwv.

Dab tsi yog lub zog tsav ntawm kev sib sib zog nqus dej hiav txwv ncig?
Hauv dej hiav txwv sib sib zog nqus, qhov tseem ceeb ntawm kev tsav tsheb yog qhov sib txawv ntawm qhov ntom ntom, tshwm sim los ntawm salinity thiab kub variations (nce salinity thiab txo qhov kub ntawm cov kua ob qho tib si nce nws ntom). Muaj feem ntau tsis meej pem txog cov khoom ntawm cov kev ncig uas yog cua thiab ceev tsav
Puas yog kev sib txhuam quab yuam conservative los yog nonconservative?
Lub zog uas tsis khaws lub zog yog hu ua nonconservative lossis dissipative rog. Kev sib txhuam yog lub zog tsis ruaj khov, thiab muaj lwm yam. Ib qho kev sib txhuam-hom quab yuam, zoo li huab cua tsis kam, yog lub zog tsis ruaj khov. Lub zog uas nws tshem tawm ntawm lub cev tsis muaj nyob rau hauv lub system rau kinetic zog
Peb puas tuaj yeem taug kev yam tsis muaj kev sib txhuam?
Txoj kev taug kev nkaus xwb uas koj tuaj yeem ua yam tsis muaj kev sib txhuam yog qhov chaw taug kev thaum txhua qhov kev ua haujlwm uas cuam tshuam nrog kev sib cuag ntawm ob qhov chaw thiab cov lus tsa suab cuam tshuam. Yog li, tsis muaj kuv tus phooj ywg, koj tuaj yeem taug kev lossis sau tsis muaj kev sib txhuam
Lub zog ntawm kev sib txhuam nyob ntawm dab tsi?
Kev sib txhuam nyob ntawm ib feem ntawm qhov smoothness ntawm qhov chaw sib cuag, yuav tsum muaj zog ntau dua kom txav tau ob qhov chaw dhau ib leeg yog tias lawv ntxhib dua li yog tias lawv du
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
