Angular acceleration (α) tuaj yeem txhais tau tias lub kaum sab xis ceev (ω) faib los ntawm kev ceev lub sijhawm (t). Xwb, pi (π) multiplied by drive speed (n) muab faib los ntawm kev ceev lub sij hawm (t) muab faib ua 30. Qhov no kev sib npaug yields tus qauv angular acceleration SI unit of radians per second squared (Rad/sec^2).

Tsuas yog li ntawd, angular acceleration formula yog dab tsi?

Angular acceleration α txhais tau tias yog tus nqi hloov ntawm lub kaum sab xis ceev. Hauv kev sib npaug daim ntawv, angular acceleration yog qhia raws li nram no: α = ΔωΔt α = Δ ω Δ t, qhov twg Δω yog qhov hloov hauv lub kaum sab xis nrawm thiab Δt yog qhov hloov pauv ntawm lub sijhawm. Cov units ntawm angular acceleration yog (rad/s)/s, or rad/s2.

Ib yam li ntawd, angular acceleration nyob ntawm dab tsi? Nyob rau hauv rotational motion, torque yuav tsum tau tsim ib tug angular acceleration ntawm ib yam khoom. Tus nqi ntawm torque yuav tsum tau tsim ib angular acceleration nyob ntawm kev faib ntawm qhov loj ntawm cov khoom. Lub sijhawm ntawm inertia yog tus nqi uas piav qhia txog kev faib khoom.

Dhau li saum toj no, yuav ua li cas acceleration raug xam?

Rearrange qhov sib npaug F = ma los daws rau kev ceev . Koj tuaj yeem hloov cov qauv no ib puag ncig los daws rau kev ceev los ntawm kev faib ob sab los ntawm qhov loj, yog li: a = F / m. Yuav nrhiav tau kev ceev , tsuas yog faib cov quab yuam los ntawm qhov loj ntawm cov khoom tau nrawm.

Dab tsi yog angular acceleration sib npaug?

Nws yog qhov kev hloov hauv lub lub kaum sab xis nrawm, muab faib los ntawm kev hloov hauv lub sijhawm. Qhov nruab nrab angular acceleration yog qhov kev hloov hauv lub kaum sab xis nrawm, muab faib los ntawm kev hloov hauv lub sijhawm. Cov angular acceleration yog vector uas taw tes rau hauv ib qho kev taw qhia raws qhov kev sib hloov axis.
