Cov SUV Kev sib npaug yog siv thaum acceleration tsis tu ncua thiab tshaj tawm hloov. Yog tias qhov ceev tsis tu ncua, koj tuaj yeem ua tau siv qhov ceev, nrug thiab sij hawm daim duab peb sab. Lawv tuaj yeem siv los ua haujlwm tawm qhov pib thiab qhov kawg ceev, lub sijhawm, kev tawg thiab kev nrawm, yog tias tsawg kawg yog peb qhov ntau. paub.

Xav txog qhov no, dab tsi yog 5 suvat equations?

Lawv hu ua SUVAT sib npaug vim tias lawv muaj cov hauv qab no sib txawv: s - nrug, u - pib nrawm ,v- nrawm lub sijhawm t, a - kev ceev thiab lub sijhawm.

Ib sab saum toj, suvat yog dab tsi? Cov SUV equations yog kinematics equations nyob rau hauv physics rau motion nyob rau hauv tas li acceleration. Txhua tsab ntawv ntawm SUV sawv cev rau ntau qhov sib txawv raws li hauv qab no: S: tshem tawm. U: pib tshaj tawm. V: kawg velocity.

Ib yam li ib tug yuav nug, yog V pib lossis qhov kawg tshaj tawm?

Pib Velocity Formula. Kev nrawm yog tus nqi uas qhov chaw ntawm ib qho khoom hloov pauv mus rau lub sijhawm. Cov pib tshaj tawm , v i yog cov nrawm ntawm cov khoom ua ntej acceleration ua rau muaj kev hloov. Tom qab nrawm rau qee lub sijhawm, qhov tshiab nrawm yog cov qhov kawg ceev , v f.

Yuav ua li cas koj nrhiav tau nro nyob rau hauv ib txoj hlua?

Cov nruj nyob rau hauv ib tug muab strand ntawm txoj hlua los yog txoj hlua yog qhov tshwm sim ntawm cov quab yuam rub ntawm txoj hlua los ntawm qhov kawg. Raws li kev ceeb toom, quab yuam = huab hwm coj × acceleration. Piv txwv tias txoj hlua yog ncab kom nruj, txhua qhov kev hloov pauv hauv kev nrawm lossis loj hauv cov khoom uas txoj hlua txhawb nqa yuav ua rau muaj kev hloov pauv hauv nruj hauv txoj hlua.
