Nws yog piav nyob rau hauv cov nqe lus ntawm kev khiav tawm, nyob deb, ceev , kev ceev , lub sijhawm thiab ceev. Jogging, tsav tsheb, thiab txawm tias tsuas yog taug kev yog txhua txhua hnub piv txwv ntawm kev txav. Kev sib raug zoo ntawm cov khoom no yog hu ua qhov sib npaug ntawm kev txav.
Piv txwv li, 5 qhov sib npaug ntawm kev txav yog dab tsi?
Yog peb paub peb ntawm no tsib kinematicvariables- Δ x, t, v 0, v, a Delta x, t, v_0, v, aΔx, t, v0, v, adelta, x, comma, t, comma, v, start subscript, 0, end subscript, comma, v, comma, a-rau ib qho khoom siv tsis tu ncua acceleration, peb tuaj yeem siv cov qauv kinematic, saib hauv qab no, los daws rau ib qho ntawm qhov tsis paub sib txawv.
Qhov thib ob, Newton's 3 txoj cai yog dab tsi? Qhov thib peb txoj cai hais tias rau txhua qhov kev nqis tes ua (lub zog) hauv qhov xwm txheej muaj qhov sib npaug thiab tawm tsam. Hauv lwm lo lus, yog tias cov khoom A tawm dag zog ntawm cov khoom B, ces qhov khoom B kuj tseem muaj zog sib npaug ntawm cov khoom A. Daim ntawv ceeb toom tias cov quab yuam tau tawm ntawm cov khoom sib txawv.
Ua raws li qhov kev pom no, tus qauv rau kev tshaj tawm hauv kev sib npaug ntawm kev txav yog dab tsi?
Hais txog qhov no officially, feem ntau ib equation ofmotion M yog qhov ua haujlwm ntawm txoj haujlwm r ntawm cov khoom, nws ceev (thawj zaug derivative ntawm r, v = drdt), thiab nws kev ceev (qhov thib ob derivative ntawm r, a = d2rdt ua2), thiab lub sijhawm t.
Tus qauv ntawm lub zog yog dab tsi?
Cov qauv rau zog hais tias zog isequal rau mass (m) multiplied by acceleration (a). Yog tias koj muaj ob qho ntawm peb qhov sib txawv, koj tuaj yeem daws qhov thib peb. quab yuam ntsuas hauv Newtons (N), qhov hnyav hauv kilograms (kg), thiab acceleration hauv meters ib ob squared (m / s2).

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 txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Dab tsi yog qee qhov piv txwv ntawm qhov sib npaug ntawm kev txav mus los?
Kev sib npaug ntawm Kev Sib Tw Rau Cov Khaub Ncaws Kev Ua Si nrawm nrawm, tsav tsheb, thiab txawm tias tsuas yog taug kev yog txhua txhua hnub piv txwv ntawm kev txav. Kev sib raug zoo ntawm cov khoom no yog hu ua qhov sib npaug ntawm kev txav
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
