Galileo Galilei
Ib yam li ntawd, nws yog nug, leej twg nrhiav tau qhov sib npaug ntawm cov lus tsa suab?
Galileo
Tsis tas li ntawd, 3 qhov sib npaug ntawm kev txav yog dab tsi? Peb Qhov Kev Sib Tw Ntawm Kev Sib Tw. Peb qhov sib npaug ntawm kev txav v = u + at; s = ut + (1/2) at2 thiab v2 = ua2 + 2 raws li tuaj yeem muab tau nrog kev pab ntawm cov duab raws li tau piav qhia hauv qab no. Xav txog qhov ceev - Lub sijhawm teeb tsa ntawm lub cev qhia hauv daim duab hauv qab no. Ceev ceev - Lub sijhawm teeb tsa los muab qhov sib npaug ntawm cov lus tsa suab.
Ua li no, 4 qhov sib npaug ntawm kev txav yog dab tsi?
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 tag nrho cov piv txwv ntawm kev txav txhua hnub. Kev sib raug zoo ntawm cov khoom no yog hu ua qhov sib npaug ntawm kev txav.
Dab tsi yog 5 qhov sib npaug ntawm kev txav?
Koj yuav tsum muaj peev xwm daws tau txhua tus lej kinematic hais txog qhov sib npaug ntawm cov lus tsa suab los ntawm kev xaiv ib qho ntawm tsib qhov sib npaug. Lawv koom nrog cov kev hloov pauv hloov pauv, pib tshaj tawm, qhov kawg tshaj tawm, kev ceev , thiab lub sijhawm luv.

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
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
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
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
