Kev nrawm txhais tau tias nrawm yog xoom.
Yuav ua li cas thaum nrawm nrawm?
Kev txav mus tas li: Thaum ib qho khoom txav mus tas li,nws tsis hloov kev taw qhia lossis nrawm thiab yog li sawv cev raws li txoj kab ncaj nraim thaum kos raws li kev ncua sij hawm.. … Muab ib daim duab raws li nyob rau hauv, peb tuaj yeem xam qhov nrawm los ntawm qhov kev hloov ntawm qhov kev ncua deb ntawm qhov kev hloov ntawm lub sijhawm.
Puas qhov nrawm nrawm sib npaug mus tas li acceleration?
Txoj kev mus rau qhov nrawm nrawm txhais tau tias koj mus ntawm qhov nrawm tib yam nkaus li tsis tu ncua. Yog tias koj muaj qhov nrawm nrawm, qhov no txhais tau tias koj muaj xoom acceleration… Yog hais tias koj mus nrog ib tug acceleration tsis tu ncua, koj qhov ceev yog ib txwm hloov, tab sis nws hloov los ntawm ib tug zoo ib yam nyob rau hauv ib ob.
Puas 0 nrawm txhais tau tias 0 acceleration?
Hauv kev xaiv (C), xoom tshaj tawm tsis txhais tau tias qhov nrawm yog xoom Piv txwv li, thaum lub pob tawm ntawm qhov siab, nws qhov nrawm yuav yog xoom tab sis acceleration exerted vim lub ntiajteb txawj nqus yuav tsis xoom yog li kev xaiv (C) yog lawm. Hauv kev xaiv (D), qhov ceev tsis tu ncua tsis txhais tau tias kev nrawm yog xoom.
Puas qhov nrawm txhais tau tias kev nrawm yog xoom?
Txoj kev nrawm txhais tau tias qhov nrawm yog xoom. Qhov kev hloov ntawm kev tshaj tawm nyob rau hauv ib lub sij hawm luv luv sib npaug ntawm thaj chaw nyob rau hauv lub acceleration graph tshaj lub sij hawm ntawd. Hauv qhov no, qhov nrawm tsis hloov pauv, yog li tsis tuaj yeem muaj qhov chaw nyob hauv qab daim duab nrawm.
