Kev sib npaug ntawm kev txav Rau Uniform Acceleration
Jogging, tsav tsheb, thiab txawm tias tsuas yog taug kev yog txhua hnub piv txwv ntawm tsab ntawv tsa suab . Kev sib raug zoo ntawm cov khoom no yog hu ua tus kev sib npaug ntawm kev txav.
Kuj nug, 5 qhov sib npaug ntawm kev txav yog dab tsi?
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.
Tsis tas li ntawd, muaj pes tsawg qhov sib npaug ntawm kev txav muaj? peb equations
Ntawm no, 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.
Thawj txoj cai lij choj yog dab tsi?
Newton tus thawj txoj cai ntawm kev txav feem ntau hais tias. Ib yam khoom ntawm so nyob ntawm so thiab ib qho khoom nyob rau hauv tsab ntawv tsa suab nyob hauv tsab ntawv tsa suab nrog tib lub nrawm thiab nyob rau tib qho kev taw qhia tshwj tsis yog ua raws li lub zog tsis sib npaug.

Dab tsi yog ib qho piv txwv ntawm cov khoom sib txuas ntawm kev sib npaug?
Kev rho tawm (Tsis yog Commutative) Tsis tas li ntawd, kev faib, kev sib xyaw ntawm cov dej num thiab cov lej sib npaug yog ob qho piv txwv zoo uas tsis yog kev sib txuas
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 sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
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
