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). Acceleration kuj yog vector kom muaj nuj nqis, yog li nws suav nrog ob qho tib si loj thiab kev taw qhia.
Koj daws tau qhov nrawm hauv physics li cas?
Kev ntsuas nrawm suav nrog faib nrawm los ntawm lub sijhawm - lossis hais txog SI units, faib cov ntsuas ib ntus [m / s] los ntawm qhov thib ob [s]. Kev faib nrug los ntawm lub sij hawm ob zaug yog tib yam li kev faib nrug los ntawm lub square ntawm lub sij hawm. Yog li SI unit ntawm acceleration yog tus ' meter ' ib ob squared.
Yuav ua li cas koj xam acceleration ib kauj ruam?
Siv tus qauv los nrhiav kev nrawm.
Ua ntej sau koj qhov kev sib npaug thiab tag nrho cov kev hloov pauv tau muab. The equation is a=Δv / Δt=(vf - vi)/(tf- ti). Tshem tawm qhov pib tshaj tawm los ntawm qhov kawg tshaj tawm, ces faib cov txiaj ntsig los ntawm lub sijhawm luv. Qhov kawg tshwm sim yog koj qhov nruab nrab acceleration nyob rau lub sijhawm ntawd.
Tus nqi nruab nrab acceleration yog dab tsi?
Average acceleration is the rate of speed change: -a=ΔvΔt=vf−v0tf−t0, qhov −a yog qhov nruab nrab acceleration, v yog tshaj tawm, thiab t yog sij hawm. (Lub bar hla qhov nruab nrab acceleration.)
Puas acceleration a physics?
Lub ntsiab lus ntawm acceleration yog:Acceleration yog tus vector kom muaj nuj nqis uas txhais tau tias yog tus nqi ntawm qhov khoom hloov nws qhov nrawm. Ib qho khoom nrawm nrawm yog tias nws hloov nws qhov nrawm.
