Acceleration yog Qhov thib ob derivative ntawm kev hloov pauv nrog rau lub sijhawm, Los yog thawj qhov kev sib tw ntawm kev tshaj tawm nrog rau lub sijhawm: Cov txheej txheem thim rov qab: Kev koom ua ke . Ceev ceev yog ib ib feem ntawm acceleration dhau sijhawm. Kev khiav tawm yog ib ib qho ntawm kev nrawm dhau lub sijhawm.

Khaws qhov no rau hauv kev xav, yuav ua li cas thaum koj sib xyaw acceleration?

Los ntawm txhais, kev ceev yog thawj derivative ntawm nrawm nrog rau lub sijhawm. Es tsis txhob sib txawv tshaj tawm mus nrhiav kev ceev , integrate acceleration nrhiav kev nrawm. Qhov no muab peb qhov sib npaug ntawm lub sijhawm. Yog peb xav kev ceev yog tas li, peb tau qhov thiaj li hu ua thawj qhov sib npaug ntawm cov lus tsa suab [1].

Qhov thib ob, yuav ua li cas yog tias koj koom nrog kev hloov chaw? Hauv kev nkag siab ncaj qha rau lej, tus ib qho ntawm hloov chaw nrog rau lub sij hawm tsuas yog ib tug tas mus li ntawm kev koom ua ke . Yog koj xav txog kev tshaj tawm raws li tus nqi hloov ntawm hloov chaw , koj ua tau xav txog hloov chaw raws li tus nqi hloov ntawm ib qho taw tes, yog li ntawd tus ib qho ntawm hloov chaw yuav tsuas yog ib qho point.

Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov tseem ceeb ntawm txoj hauj lwm sawv cev?

Cov ib qho ntawm txoj hauj lwm raws ib lub axis w.r.t lwm axis muab koj thaj chaw mapped los ntawm seem ntawm qhov nkhaus thiab x-axis. Cov ib qho ntawm txoj hauj lwm hais txog lub sij hawm muab rau koj kom muaj nuj nqis nrog units "meters vib nas this".

Tus qauv ntawm acceleration yog dab tsi?

Kev nrawm (a) yog qhov hloov pauv hauv qhov nrawm (Δv) dhau qhov kev hloov pauv hauv lub sijhawm (Δt), sawv cev los ntawm kev sib npaug 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). Kev nrawm kuj yog ib qho vector kom muaj nuj nqis, yog li nws suav nrog ob qho tib si loj thiab kev coj ua.
