Acceleration yog txhais nruj me ntsis raws li lub sijhawm hloov pauv ntawm qhov nrawm vector. Deceleration, ntawm qhov tod tes, yog acceleration uas ua rau txo qis hauv "ceev". Yog tias peb xav txog kev txav mus los hauv ib qhov ntev, ces qhov deceleration tshwm sim thaum cov paib ntawm qhov nrawm thiab nrawm yog qhov sib txawv. …
Kev sib raug zoo ntawm kev nrawm thiab kev qeeb yog dab tsi?
Nug acceleration. Deceleration ib txwm hais txog acceleration nyob rau hauv cov kev taw qhia opposite rau cov kev taw qhia ntawm lub tshaj tawm. Txoj kev nrawm ib txwm txo qis. Tsis zoo acceleration, txawm li cas los xij, yog acceleration nyob rau hauv qhov tsis zoo kev taw qhia nyob rau hauv lub xaiv coordinate system.
txhais tau tias yog acceleration thiab deceleration?
Lo lus acceleration yog siv los piav qhia txog kev hloov pauv. Nws yog ib qho uas siv acceleration los txhais tau tias ceev thiab lo lus deceleration txhais tau tias qeeb. Hais lus nruj me ntsis, txawm li cas los xij, kev nrawm piav qhia ob hom kev txav.
Thaum twg qhov khoom tuaj yeem nrawm thiab qeeb?
Thaum twg lub acceleration ntawm cov khoom nyob rau hauv tib txoj kev raws li lub nrawm, lub tsheb yog ceev thiab hais tias yuav tsum accelerating. Nyob rau tib lub sij hawm, yog hais tias lub acceleration yog nyob rau hauv lub opposite direction ntawm lub ceev, lub tsheb yog hais tias nws yuav qeeb thiab decelerating.
Puas yog tus qauv ntawm acceleration thiab deceleration tib yam?
Kev txo qis yog qhov ntxeev ntawmkev ceev. Lub deceleration yuav suav los ntawm faib qhov kawg tshaj tawm rho tawm qhov pib tshaj tawm, los ntawm lub sijhawm yuav coj mus rau qhov kev poob qis no. Cov mis rau acceleration tuaj yeem siv ntawm no, nrog rau qhov tsis zoo, txhawm rau txheeb xyuas tus nqi deceleration.
