Tsis tu ncua acceleration

  1. Txij li thaum peb siv meters thiab vib nas this raws li peb cov chav hauv paus, peb yuav ntsuas kev ceev nyob rau hauv meters ib feeb ib ob.
  2. Piv txwv li, yog hais tias qhov ceev ntawm ib tug particle txav nyob rau hauv ib tug ncaj kab hloov uniformly (ntawm a tas li tus nqi hloov pauv) los ntawm 2 m / s mus rau 5 m / s dhau ib thib ob, ces nws acceleration tsis tu ncua yog 3m/s2.

Yog li ntawd, dab tsi yog qhov acceleration nyob rau hauv physics?

Qee zaum ib ceev cov khoom yuav hloov nws qhov nrawm los ntawm tib tus nqi txhua ob. Qhov no yog hu ua a acceleration tsis tu ncua vim lub nrawm hloov los ntawm a tas li tus nqi txhua thib ob. Ib yam khoom nrog a acceleration tsis tu ncua yuav tsum tsis txhob totaub nrog ib yam khoom nrog a tas li ceev.

Tsis tas li ntawd, koj yuav ua li cas thiaj nrhiav tau qhov nrawm nrawm yam tsis muaj sijhawm? 3 Teb. v2 = u2 + 2as rau ib qho particle undergoing acceleration tsis tu ncua . Hauv qhov no pf qhov sib txawv kev ceev , cov qauv no tuaj yeem siv rau xam qhov "nruab nrab" kev ceev , uas sawv cev rau tag nrho cov kev hloov nyob rau hauv tshaj tawm tag nrho cov kev hloov nyob rau hauv sij hawm.

Ntxiv mus, dab tsi yog lub mis rau uniform acceleration?

Thaum ib yam khoom yog ceev ntawm a tas li ntsuas nws cov lus tsa suab tuaj yeem ua qauv los ntawm ob qho yooj yim kev sib npaug , a = (Vf - Vi) / t and d = 1/2 (Vf + Vi) × t.

Tus qauv ntawm kev hloov pauv yog dab tsi?

Taw qhia rau lub Kev khiav tawm thiab Acceleration Equation Nws nyeem: Kev khiav tawm sib npaug qhov qub tshaj tawm los ntawm lub sij hawm ntxiv rau ib nrab ntawm qhov acceleration multiplied los ntawm lub square ntawm lub sij hawm. Ntawm no yog ib qho piv txwv teeb meem thiab nws txoj kev daws teeb meem uas qhia txog kev siv qhov sib npaug: Ib qho khoom txav nrog qhov nrawm ntawm 5.0 m / s.
