Lub zog centripetal yog ntsuas hauv Newton thiab yog xam Raws li qhov loj (hauv kg), muab faib los ntawm tangential tshaj tawm (hauv meters ib ob) squared, muab faib los ntawm lub vojvoog (hauv meters). Qhov no txhais tau hais tias yog tangential tshaj tawm ob npaug, lub zog yuav quadruple.

Ntxiv mus, dab tsi yog lub mis rau xam lub zog centrifugal?

Txiav txim siab qhov nrawm ntawm qhov khoom. Nws tuaj yeem sib npaug li 5 m / s. Yog koj paub cov angular tshaj tawm tsuas yog, koj tuaj yeem siv cov mis v = ω * 2 * π * r los xam qhov nrawm. Siv qhov sib npaug ntawm lub zog centrifugal: F = m * v^2 / r.

Tsis tas li ntawd, qhov ntsuas ntawm centripetal acceleration yog dab tsi? Centripetal acceleration (a) yog ntsuas hauv meters ib thib ob ib ob (ms-2). Nws yog ib txwm coj mus rau qhov chaw ntawm lub voj voog.

Kuj paub yog, dab tsi yog lub zog centripetal hauv physics?

A lub zog centripetal (los ntawm Latin centrum, "center" thiab petere, "mus nrhiav") yog a zog uas ua rau lub cev ua raws txoj kev nkhaus. Nws cov kev taw qhia yog ib txwm orthogonal mus rau lub zog ntawm lub cev thiab mus rau lub taag point ntawm lub instantaneous centre ntawm curvature ntawm txoj kev.

Vim li cas lub zog centripetal sib npaug li qhov hnyav?

Yog tag nrho zog ua haujlwm ntawm lub cev yog C thiab W ( centripetal thiab hnyav ) thiab lub cev tsis txav (a acceleration a = 0), f = ma = 0 = C + W; ces C = -W, the lub zog centripetal yuav tsum yog sib npaug thiab opposite rau lub hnyav . Thiab yog vim li cas lub zog centripetal thiab hnyav yog " sib npaug "hauv koj li cas.
