Nyob rau hauv rotational motion, tangential acceleration isa ntsuas sai npaum li cas a tangential ceev hloov. Italways ua perpendicular mus rau centripetal kev ceev ntawm cov khoom rotating. Nws yog sib npaug rau cov angular acceleration α, lub sij hawm lub voj voog ntawm kev sib hloov.

Ntxiv mus, qhov txawv ntawm tangential thiab angular acceleration yog dab tsi?

Tangential acceleration tshwm sim los ntawm qhov hloov pauv loj ntawm lub tangential ceev ntawm ib yam khoom. Anobject tuaj yeem txav mus los hauv a lub voj voog thiab tsis muaj tangentialacceleration ntawm lub cev . Tsis muaj tangential acceleration yooj yim txhais tau tias angular acceleration ntawm cov khoom yog xoom thiab theobject yog txav nrog a tas li lub kaum sab xis ceev.

Yuav ua li cas yog tangential thiab angular velocity? Rau ib qho khoom rotating txog ib qho axis, txhua qhov taw tes ntawm cov khoom muaj tib yam angular tshaj tawm . Cov tangentialvelocity ntawm ib qho taw tes yog proportional rau nws qhov kev ncua deb ntawm lub axis ntawm kev sib hloov. Angular tshaj tawm muaj unitsrad/s.

Hauv qhov no, tangential thiab centripetal acceleration cuam tshuam li cas?

Kev taw qhia ntawm tangential acceleration istangent rau lub voj voog whereas cov kev taw qhia ntawm centripetalacceleration yog radially sab hauv mus rau qhov chaw ntawm lub voj voog.

Dab tsi ua rau tangential acceleration?

Tangential thiab centripetal kev ceev Cov tangential tiv at yog vim qhov kev hloov pauv ntawm kev ceev ntawm kev hla mus, thiab cov ntsiab lus raws qhov nkhaus ntawm qhov taw qhia ntawm qhov nrawm vector (los yog nyob rau hauv oppositedirection).
