Ib yam khoom nyob hauv kev sib npaug yog; Lub resultant quab yuam ua rau cov khoom yog xoom. Tus lej ntawm lub sijhawm ua haujlwm ntawm ib qho khoom yuav tsum yog xoom.
Ib yam li ntawd, nws raug nug, dab tsi yog cov xwm txheej rau kev sib npaug ntawm lub cev nruj?
Ob tug tej yam kev mob rau cov equilibrium ntawm lub cev nruj (xws li meter stick) yog 1. vector sum of force on the lub cev yuav tsum yog xoom thiab 2. vector sum ntawm torques ntawm lub lub cev yuav tsum yog xoom.
Ib yam li ntawd, qhov xwm txheej thib ob ntawm kev sib npaug yog dab tsi? Cov mob thib ob tsim nyog kom ua tiav kev sib npaug Yuav tsum zam kom tsis txhob muaj kev sib hloov ceev (tswj lub angular tshaj tawm. kev sib npaug yog tias nws qhov kev sib hloov yog tas li thiab tseem tsis hloov pauv los ntawm cov rog ua rau nws.
Kuj paub, 3 hom kev sib npaug yog dab tsi?
Muaj peb hom equilibrium : ruaj khov, tsis ruaj khov, thiab nruab nrab. Cov duab thoob plaws qhov module no qhia txog ntau yam piv txwv.
Ob hom kev sib npaug yog dab tsi?
Muaj ob txawv hom equilibrium : dynamic kev sib npaug thiab static kev sib npaug.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov tseem ceeb ntawm cov coefficients hauv kev sib npaug sib npaug?
Coefficients yog ib qho tseem ceeb los ua pov thawj txoj cai ntawm kev txuag ntawm huab hwm coj. Cov coefficients nyob rau hauv ib qho kev sib npaug ntawm cov tshuaj sib npaug qhia cov txheeb ze ntawm moles ofreactants thiab cov khoom. Los ntawm cov ntaub ntawv no, lub Cheebtsam ntawm reactants thiab cov khoom yuav raug xam. Koj tuaj yeem txiav txim seb tus lej ntawm moles ntawm cov khoom
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
