A zog yog hais tias yog tsis yog - kev saib xyuas thaum ua hauj lwm tawm tsam nws tsis tseg los ntawm lub cev uas yog tsiv los ntawm lub zog . Ib qho piv txwv ntawm tsis yog - kev saib xyuas hom ntawm zog yog kev sib txhuam zog . Thaum lub cev txav tawm tsam kev sib txhuam , kev ua haujlwm yuav tsum tau kov yeej kev sib txhuam . Kev ua haujlwm yog lub zog thiab yog li nws tsis tuaj yeem ploj.
Tsis tas li ntawd, kev sib txhuam puas yog lub zog ruaj khov?
A conservative zog yog a zog nrog rau cov cuab yeej uas tag nrho cov hauj lwm ua nyob rau hauv txav ib particle ntawm ob lub ntsiab lus yog ywj siab ntawm coj txoj kev. Gravitational zog yog ib qho piv txwv ntawm a conservative zog , thaum kev sib txhuam quab yuam yog ib qho piv txwv ntawm qhov tsis yog conservative zog.
Ib tug kuj yuav nug, dab tsi yog lub ntsiab lus ntawm kev tsis saib xyuas lub zog? Tsis yog - conservative rog yog dissipative zog xws li kev sib txhuam lossis cua tsis kam. Cov no zog coj lub zog tawm ntawm lub cev thaum lub cev ua haujlwm, lub zog uas koj tsis tuaj yeem rov qab los. Cov no zog yog txoj kev nyob; yog li ntawd nws tseem ceeb rau qhov khoom pib thiab nres.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog lub zog ruaj khov thiab tsis muaj kev tswj hwm?
Definition: Txoj hauj lwm a conservative zog ua ntawm ib qho khoom txav los ntawm A mus rau B yog txoj kev ywj pheej - nws tsuas yog nyob ntawm qhov kawg ntawm cov lus tsa suab. Rau ib tsis yog - kev saib xyuas (los yog dissipative) zog , txoj haujlwm ua tiav los ntawm A mus rau B nyob ntawm txoj kev coj mus. Piv txwv li: kev sib txhuam thiab cua tsis kam.
Dab tsi yog conservative quab yuam pov thawj tias lub zog gravitational yog kev saib xyuas thaum kev sib txhuam quab yuam tsis yog kev saib xyuas?
Yog li txhua txoj haujlwm kab rov tav ua tiav ntawm cov khoom yuav tsis suav nrog gravitational ua haujlwm. Li no lub gravitational ua haujlwm yog kev saib xyuas . Ntawm qhov tod tes kev sib txhuam ua hauj lwm tiav nce nrog txoj kev them los ntawm cov khoom, txawm tias cov kev sib txhuam quab yuam nyob tas li.

Kev saib xyuas ntawm kev ruaj ntseg sab hauv txawm tias muaj kev hloov pauv hauv ib puag ncig sab nraud yog hu ua homeostasis
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
Vim li cas lub caij nplooj ntoos hlav quab yuam tsis zoo?
Lub caij nplooj ntoos hlav quab yuam yog hu ua ib tug restoringforce vim hais tias lub zog exerted los ntawm lub springis ib txwm nyob rau hauv opposite kev coj mus rau qhov chaw. Qhov no yog vim li cas thiaj muaj lub cim tsis zoo nyob rau hauv Hooke txoj cai sib npaug.Pulling down on a spring stretches the springdownward, which results in the spring exerting an upwardforce

Vim li cas cov hlwb yuav tsum muaj kev ruaj ntseg sab hauv?
Cov hlwb uas tsim cov kab mob muaj lub luag haujlwm loj - ua kom cov kab mob noj qab haus huv kom lawv loj hlob thiab rov tsim dua. Kev saib xyuas ntawm qhov ruaj khov, tsis tu ncua, sab hauv yog hu ua homeostasis. Koj lub hlwb ua qhov no los ntawm kev tswj hwm lawv qhov chaw nyob sab hauv kom lawv txawv ntawm qhov chaw sab nraud
