Peb feem ntau hom kev ua graphs yog acceleration vs. time daim duab , ceev vs daim duab thiab hloov chaw vs daim duab.

Yog li ntawd, dab tsi yog motion graphs hauv physics?

Qhov thib ob feem ntau siv daim duab ntawm tsab ntawv tsa suab yog velocity (nqe v. time) thiab acceleration (velocity v. The daim duab ntawm qhov nrawm yog qhov nkhaus thaum lub daim duab ntawm acceleration yog linear. Txoj kab nqes ntawm ib kab tangent mus rau daim duab ntawm nrug v. lub sij hawm yog nws instantaneous tshaj tawm.

Qhov thib ob, tus qauv ntawm kev tshaj tawm yog dab tsi? Velocity Formula . Cov ceev yog lub sij hawm tus nqi hloov pauv. Yog tias 'S' yog qhov hloov pauv ntawm ib qho khoom hauv qee lub sijhawm 'T', ces qhov ceev yog sib npaug, v = S/T. Cov units ntawm ceev yog m/s los yog km/hr.

Yog li ntawd, dab tsi yog daim duab hauv physics?

A daim duab Hauv paus ntsiab lus xaus li cas ib qho quanty hloov yog tias lwm qhov ntau uas cuam tshuam nrog nws kuj hloov. Noj cov kev xav ntawm ib tug me nyuam kawm ntawv kawm astronomy los yog physics , daim duab muaj txiaj ntsig vim lawv tuaj yeem sau ntau cov ntaub ntawv rau hauv ib daim duab.

Dab tsi yog qhov txawv ntawm qhov nrawm thiab nrawm?

Cov lus teb luv luv yog qhov ntawd ceev yog cov ceev nrog kev taw qhia, thaum ceev tsis muaj kev taw qhia. Ceev yog scalar kom muaj nuj nqis-nws yog qhov loj ntawm qhov ceev . Ceev yog ntsuas nyob rau hauv units ntawm qhov kev ncua deb muab faib los ntawm lub sij hawm (piv txwv li, mais ib teev, ko taw ib ob, meters ib ob, thiab lwm yam).
