Yog tias lub zog ntawm ib qho khoom sib npaug, lub zog ntawm lub zog yog xoom. Yog hais tias cov rog tsis sib npaug, cov teebmeem tsis thim ib leeg. Txhua lub sij hawm lub zog ua rau ib yam khoom tsis sib npaug, lub zog ntawm lub zog tsis yog xoom, thiab tsab ntawv tsa suab ntawm cov khoom hloov.
Raws li kev sib raug zoo, lub zog tsis sib npaug ntawm qhov khoom muaj txiaj ntsig dab tsi?
Yog ib khoom muaj net zog ua rau nws, nws yuav nrawm. Cov khoom yuav ua kom nrawm, qeeb lossis hloov kev coj ua. Ib tsis sib npaug zog (net zog ) acting ib khoom hloov nws ceev thiab/los yog kev taw qhia ntawm kev txav. Ib tsis sib npaug zog yog ib qho tsis pom kev zog uas ua rau muaj kev hloov pauv.
Ib tug kuj yuav nug, peb cov piv txwv ntawm kev tsis sib haum xeeb yog dab tsi? Lub zog uas ua rau lub nqa nce mus yog lub zog tsis sib npaug vim nws loj dua li lwm lub zog ua haujlwm ntawm lub nqa (xws li lub zog gravitational). Ib qho piv txwv yooj yim yuav yog lub tsheb uas nrawm ntawm txoj kev. Muaj kev sib txhuam quab yuam los ntawm lub tsheb vim huab cua tsis kam, uas tawm tsam cov tsab ntawv tsa suab ntawm lub tsheb.
Hauv qhov no, qhov tsis sib haum xeeb ua rau muaj dab tsi?
Tsis sib npaug zog ua tau ua rau ib yam khoom los hloov nws cov lus tsa suab. Tsis sib npaug zog hloov cov lus tsa suab ntawm ib yam khoom. Qhov no tshwm sim nyob rau hauv ob txoj kev. Yog hais tias ib yam khoom yog so thiab ib qho tsis sib npaug zog thawb lossis rub cov khoom, nws yuav txav mus.
Koj ua li cas thiaj paub tias lub zog sib npaug lossis tsis sib npaug?
Rau txiav txim yog tias tus zog ua raws li qhov khoom yog balanced los yog tsis sib npaug , ib qho kev ntsuam xyuas yuav tsum xub ua rau txiav txim dab tsi zog tab tom ua raws li qhov khoom thiab nyob rau hauv qhov kev taw qhia. Yog ob tug zog yog vaj huam sib luag thiab opposite direction, ces tus zog hais tias yog 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
Koj tuaj yeem qhia tau li cas yog tias ob qhov sib npaug sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv qhov sib npaug seb puas yog ob kab sib npaug los ntawm kev sib piv lawv cov nqes hav. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel. Yog tias txoj kab nqes sib txawv, cov kab tsis sib npaug. Tsis zoo li cov kab sib luag, cov kab perpendicular sib tshuam
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
Yuav ua li cas yog hais tias cov tshuaj sib npaug tsis sib npaug?
Yog tias qhov sib npaug ntawm cov tshuaj tsis sib npaug ces nws ua txhaum txoj cai lij choj ntawm Kev Tiv Thaiv MASS uas tau muab los ntawm Antoine Lavoiser, nws hais tias tus naj npawb ntawm cov atoms nyob rau sab reactant yuav sib npaug ntawm cov atoms nyob rau hauv cov khoom ntawm tib lub ntsiab los yog peb. tuaj yeem hais tias atoms tsis tuaj yeem rhuav tshem los yog ua tau
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
