Nyob rau hauv classical mechanics, ib tug particle yog nyob rau hauv mechanicalquilibrium yog hais tias lub net quab yuam ntawm qhov particle yog xoom. Byextension, lub cev system ua los ntawm ntau qhov chaw yog nyob rau hauv mechanical equilibrium yog tias lub zog ntawm txhua qhov ntawm nws tus kheej yog xoom.
Nyob rau hauv no hais txog, dab tsi yog lub zog ntawm ib yam khoom nyob rau hauv static los yog dynamic equilibrium?
Thaum lub net zog on ib khoom yog equalto zero ces qhov no khoom yog los yog thaum so ( staticequilibrium ) lossis txav ntawm qhov nrawm nrawm ( dynamicequilibrium ).
Tsis tas li ntawd, Galileo nrhiav tau dab tsi txog kev txav lub cev thiab quab yuam hauv nws qhov kev sim nrog cov dav hlau inclined? Galileo pom tias ib lub pob yuav los so vim kev sib txhuam thiab tsis yog "txoj cai". Nws ntseeg hais tias nyob rau hauv tus tsis muaj kev sib txhuam lossis lwm yam kev tawm tsam zog , ib kab rov tav tsiv object yuav txuas ntxiv mus tsiv indefinitely (mus ib txhis).
Ib yam li ntawd, tej zaum koj yuav nug, qhov kev ntsuam xyuas yog dab tsi yog tias ib qho khoom txav mus rau hauv qhov sib npaug?
Yog ib khoom yog notacceleration nws yog nyob rau hauv kev sib npaug.
Dab tsi yog qhov xwm txheej ntawm cov khoom yuav tsum nyob rau hauv mechanical equilibrium?
Rau ib khoom ua nyob rau hauv kev sib npaug , nws yuav tsum muaj kev acceleration. Qhov no txhais tau hais tias ob qho tib si netforce thiab net torque ntawm lub khoom yuav tsum bezero.

Dab tsi organelle suav hais tias yog lub Hoobkas vim tias nws siv rau hauv raw?
Chloroplast tig hnub ci, carbon dioxide, thiab dej rau hauv cov zaub mov (qabzib). Dab tsi organelle raug suav hais tias yog 'lub Hoobkas', vim tias nws siv cov khoom siv raw thiab hloov mus rau cov khoom lag luam ntawm tes uas tuaj yeem siv los ntawm lub xovtooj? Cell membrane tiv thaiv lub cell; tswj qhov nkag mus rau hauv thiab tawm ntawm tes, kev sib txuas lus
Nws txhais li cas yog hais tias cov khoom nyob rau hauv tib kem?
Kev piav qhia: Rau cov ntsiab lus hauv kab 1,2 thiab 13-18 lub atoms nyob rau hauv tib kem muaj tib tus nqi ntawm sab nraud electrons, hu ua valence electrons. Cov kab ntawm lub atom kuj cuam tshuam rau cov nyiaj ntawm cov ntawv cog lus uas lub atom tuaj yeem koom nrog tab sis qhov no tsis yooj yim li
Lub Tuam Tsev txhais li cas thaum nws hais tias kuv ntseeg tias qhov zoo rau nyuj yog qhov zoo rau kev lag luam?
Lub tuam tsev txhais tau hais tias yog cov nyuj muaj kev hwm thiab kho tau zoo, lawv yuav yooj yim dua los tuav uas yuav ua rau cov txheej txheem zoo dua rau txhua tus neeg koom tes
Yuav ua li cas koj paub yog hais tias ib yam khoom tshiab yog tsim nyob rau hauv ib tug tshuaj sib npaug?
Muaj cov cim qhia tias muaj tshuaj lom neeg tshwm sim. Npuas daim ntawv, ib tug roj yog muab tawm, thiab lub beaker tau kub heev. Lub cim tseem ceeb tshaj plaws uas muaj tshuaj lom neeg tshwm sim yog kev tsim cov tshuaj tshiab. Cov khoom tshiab yog cov pa roj carbon, lub nkig dub, thiab dej vapor, roj tsis muaj xim
Nws txhais li cas thaum lub system nyob rau hauv equilibrium physics?
Raws li OED, lo lus equilibrium txhais tau tias '1. a Nyob rau hauv lub cev kev xav: Cov xwm txheej ntawm kev sib npaug sib npaug ntawm cov tawm tsam rog; uas lub xeev ntawm cov khoom siv nyob rau hauv uas cov rog ua raws li qhov system, los yog cov ntawm lawv cov uas tau muab rau hauv kev txiav txim siab, yog li txheej txheem uas lawv cov txiaj ntsig ntawm txhua qhov yog xoom
