Rau qhov xwm txheej ntawm lub voj voog tsis sib xws, qhov nrawm (v) ntawm cov khoom nyob rau hauv lub voj voog tsis tu ncua (los ntawm txhais). Qhov no txhais tau tias tangential acceleration, aT, yog xoom.
Vim li cas tangential acceleration zero?
Txawm li cas los xij, nrog lub zog centripetal coj mus rau perpendicular mus rau qhov nrawm nrawm, cov khoom ib txwm hloov nws txoj kev coj thiab ua kom nrawm nrawm. Yog li ntawd, thaum lub sij hawm ib tug uniform ncig tangential acceleration yog xoom vim nws qhov nrawm nrawm.
Puas tangential acceleration puas tau xoom?
Ib yam khoom tuaj yeem txav mus rau hauv lub voj voog thiab tsis muaj qhov nrawm nrawm. Tsis muaj tangential acceleration tsuas yog txhais tau tias angular acceleration ntawm cov khoom yog xoom thiab cov khoom txav nrog qhov nrawm nrawm.
Koj puas tuaj yeem muaj xoom tangential thiab nonzero centripetal acceleration?
Txhua yam uas tsis yog xoom tangential tshaj tawm yuav ua rau tsis xoom radial acceleration, yog li ntawd tib txoj kev rau radial acceleration yuav xoom yog rau sib npaug zero.
Puas tangential acceleration ib txwm tas li?
Rau qhov xwm txheej ntawm lub voj voog tsis sib xws, qhov nrawm (v) ntawm cov khoom nyob rau hauv lub voj voog tsis tu ncua (los ntawm txhais). Qhov no txhais tau tias tangential acceleration, aT, yog xoom.
