Raws li OED, lo lus equilibrium txhais tau tias 1. Kev nkag siab ntawm lub cev: Cov xwm txheej ntawm kev sib npaug sib npaug ntawm cov tawm tsam rog; lub xeev ntawm cov khoom siv qhov system nyob rau hauv uas cov rog ua raws li lub qhov system , los yog cov uas tau muab rau hauv kev txiav txim siab, yog li ntawd lawv cov txiaj ntsig ntawm txhua qhov chaw yog xoom.
Yog li ntawd, dab tsi yog txhais los ntawm lub system yog nyob rau hauv equilibrium physics?
Equilibrium , hauv physics , condition a qhov system thaum tsis yog nws lub xeev ntawm kev txav los yog nws lub zog sab hauv lub xeev zoo li hloov nrog lub sijhawm. Rau ib qho particle, kev sib npaug tshwm sim yog tias vector sum ntawm tag nrho cov zog ua raws li qhov particle yog xoom.
Tsis tas li ntawd, koj ua pov thawj li cas ib qho system nyob rau hauv equilibrium? Txhawm rau ua pov thawj tias lub cev muaj qhov sib npaug, peb tuaj yeem ua raws li txheej txheem txheej txheem.
- Kos daim duab dawb-lub cev, uas qhia tau hais tias lub zog ua haujlwm ntawm qhov khoom.
- daws cov rog hauv ob qho kev qhia yooj yim, piv txwv li, ΣFx= 0 thiab ΣFy = 0, uas yuav ua rau muaj ob qhov sib npaug los ntawm ob qhov tsis paub yuav pom.
Ntawm no, nws txhais li cas thaum lub zog nyob hauv qhov sib npaug?
Ib lub tswv yim yooj yim heev thaum cuam tshuam nrog zog yog lub tswv yim ntawm kev sib npaug los yog tshuav nyiaj li cas. Yog qhov loj thiab kev taw qhia ntawm lub zog ua yeeb yam ntawm ib yam khoom yog qhov sib npaug, ces tsis muaj net zog ua yeeb yam ntawm cov khoom thiab cov khoom yog hais tias nyob rau hauv kev sib npaug.
Lub cev puas tuaj yeem sib npaug yog tias nws nyob hauv kev txav mus los?
Yog lawm! Xws li ib kev sib npaug qhov xwm txheej yog hu ua dynamic kev sib npaug . Yog li ib yam khoom hauv equilibrium tau txawm muaj xoom tshaj tawm los yog qhov tsis-zero tshaj tawm. Static Equilibrium : Thaum twg lub net quab yuam ua rau ib yam khoom yog xoom thiab yog cov khoom tsis txav, ces nws hu ua static kev sib npaug.

Yuav ua li cas yog tus qauv chav tsev ntawm lub sij hawm thib ob txhais nyob rau hauv lub International System of Units?
Qhov thib ob (symbol: s, abbreviation: sec) yog lub hauv paus chav tsev ntawm lub sij hawm nyob rau hauv lub International System of Units (SI), feem ntau to taub thiab keeb kwm txhais tau tias yog ?1 ⁄ 86400 ntawm ib hnub - qhov tseem ceeb no tau los ntawm kev faib hnub. thawj zaug rau hauv 24 teev, ces mus rau 60 feeb thiab thaum kawg mus rau 60 vib nas this txhua
Yuav ua li cas yog lub cev nyob rau hauv static equilibrium thaum sib txawv zog ua rau nws?
Ob qho xwm txheej ntawm kev sib npaug yuav tsum tau ua kom ntseeg tau tias qhov khoom nyob hauv qhov sib npaug zoo li qub. Tsis tsuas yog yuav tsum tau tag nrho cov quab yuam ua raws li cov khoom yuav xoom, tab sis cov sum ntawm tag nrho cov torques ua raws li cov khoom yuav tsum yog xoom
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Nws txhais li cas rau lub ntiaj teb nyob rau hauv thaj chaw uas nyob tau?
Nyob rau hauv astronomy thiab astrobiology, lub circumstellar habitable zone (CHZ), los yog tsuas yog qhov chaw nyob, yog qhov ntau ntawm orbits nyob ib ncig ntawm lub hnub qub nyob rau hauv uas lub planetary nto yuav pab tau cov kua dej uas txaus atmospheric siab
Nws txhais li cas hais tias ib yam dab tsi nyob rau hauv mechanical equilibrium?
Nyob rau hauv classical mechanics, ib tug particle yog nyob rau hauv mechanicalequilibrium yog hais tias lub net quab yuam ntawm cov particle yog xoom. Byextension, lub cev lub cev ua los ntawm ntau qhov chaw yog inmechanical equilibrium yog hais tias lub net quab yuam ntawm txhua qhov ntawm nws tus kheej qhov chaw yog xoom
