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.

Yuav ua li cas rau acceleration physics?
Acceleration (a) yog qhov hloov pauv hauv qhov nrawm (Δv) dhau qhov kev hloov pauv hauv lub sijhawm (Δt), sawv cev los ntawm kab zauv a=Δv/Δt. Qhov no tso cai rau koj los ntsuas qhov nrawm nrawm npaum li cas hloov pauv hauv meters ib ob squared (m / s^2).
Thaum acceleration yog xoom?
Yog acceleration is 0, the speed is not change. Yog tias qhov nrawm tsis tu ncua (0 acceleration) ces qhov khoom yuav txuas ntxiv yam tsis tau qeeb lossis nrawm. Yuav ua li cas thaum acceleration yog xoom? Yog tsis muaj kev nrawm, ces tus khoom yuav txav mus tas li.
Ntawm dab tsi yog keeb kwm ntawm carr thiab elton mus rau rorty thiab dawb?
Ntawm 'Keeb kwm yog dab tsi?' muab cov tub ntxhais kawm qhia txog kev sib cav txog keeb kwm niaj hnub no. … Los ntawm nws qhov kev thuam tsis txaus ntseeg ntawm Carr thiab Elton thiab nws qhov kev sib tw ntawm Rorty thiab Dawb, Ntawm 'Dab Tsi Yog Dab Tsi'?
Koj puas suav qhov deceleration?
Kev qeeb qeeb yog qhov sib txawv ntawm kev nrawm. Lub deceleration yuav xam los ntawm faib qhov kawg tshaj tawm rho tawm qhov pib tshaj tawm, los ntawm tus nqi ntawm lub sij hawm yog coj mus rau qhov kev poob hauv qhov nrawm. Cov mis rau acceleration tuaj yeem siv ntawm no, nrog rau qhov tsis zoo, txhawm rau txheeb xyuas tus nqi deceleration.
Leej twg txav nrog ntau dua ntawm tangential acceleration?
Ob leeg Ana thiab Bobby tuav lub nrawm nrawm, yog li ob leeg muaj qhov nrawm nrawm ntawm xoom (yog li lawv sib npaug)! Leej twg txav nrog qhov loj dua ntawm tangential acceleration? a) Ana muaj qhov loj dua ntawm tangential acceleration. Leej twg muaj qhov loj dua ntawm centripetal acceleration?
