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 tsab ntawv tsa suab . Ib tsis sib npaug zog yog ib qho tsis pom kev zog uas ua rau muaj kev hloov hauv tsab ntawv tsa suab.
Hauv qhov no, ua li cas tsis sib npaug zog cuam tshuam rau kev txav ntawm ib qho khoom?
Tsis sib npaug zog tuaj yeem ua rau ib qho khoom hloov nws tsab ntawv tsa suab . Qhov no tshwm sim nyob rau hauv ob txoj kev. Yog ib khoom yog so thiab ib tsis sib npaug zog pushes los yog rub lub khoom , nws yuav txav mus. Tsis sib npaug zog tuaj yeem hloov qhov ceev lossis kev taw qhia ntawm ib qho khoom uas twb nyob rau hauv tsab ntawv tsa suab.
Ib yam li ntawd, lub zog dab tsi ua rau ntawm qhov khoom thaum so? Nws yog vector sum ntawm tag nrho cov xws li zog uas sib npaug zero rau ib khoom thaum so . CASE 1: Xav txog ib lub pob tawb hnyav 1kg, yog tias nws tau khaws cia rau hauv av, muaj ob zog acting ntawm nws. Cov no yog nws qhov hnyav (lub ntiajteb txawj nqus) thiab sib npaug thiab opposite zog los ntawm av (ib txwm tshuaj tiv thaiv).
Yog li ntawd, dab tsi yog 3 yam uas tsis muaj zog tuaj yeem ua rau ib qho khoom ua tau?
Kev tsis sib haum xeeb tuaj yeem ua tau mus rau ib qho kev hloov hauv kev coj, kev hloov hauv kev ceev, los yog ob qho tib si kev hloov hauv kev coj thiab kev ceev.
Dab tsi yog hom quab yuam?
Kev quab yuam yog tus neeg sawv cev sab nraud uas tsim cov lus tsa suab lossis nyiam tsim cov lus tsa suab lossis nws nres lossis txav mus los. Hauv paus, muaj ob hom rog, tiv tauj rog, thiab tsis sib cuag rog. Gravitational quab yuam, hluav taws xob quab yuam, sib nqus quab yuam, nuclear quab yuam, kev sib txhuam quab yuam yog ib co piv txwv ntawm lub zog.

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
Yuav ua li cas rau ib qho khoom wavelength thaum cov khoom txav ntawm koj?
Yog tias cov khoom txav mus rau koj, cov waves raug compressed, yog li lawv cov wavelength luv dua. Yog tias qhov khoom txav deb ntawm koj, cov nthwv dej tau nthuav tawm, yog li lawv lub wavelength ntev dua. Cov kab yog hloov mus rau ntev (redder) wavelengths --- qhov no hu ua aredshift
Yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Yuav ua li cas tshwm sim thaum lub zog pauv ntawm ib yam khoom mus rau lwm tus?
Lub zog yog pauv los ntawm ib qho khoom mus rau lwm qhov thaum muaj qhov tshwm sim tshwm sim. Lub zog los ntawm ntau hom thiab tuaj yeem hloov los ntawm ib yam khoom mus rau lwm qhov xws li cua sov, lub teeb, lossis kev txav mus los, rau npe ob peb. Daim ntawv ntawm lub zog no hu ua kinetic zog
