Axial vectors yog vector hla cov khoom ntawm txoj haujlwm qub cov duab . Piv txwv li, angularmomentum L = r × v thiab torque T = r × F yog cov axialvectors.

Ib yam li ntawd, tib neeg nug, hom vector yog angular momentum?

Angular zog yog a vector kom muaj nuj nqis (ntau qhov tseeb, ib qho pseudovector) uas sawv cev rau cov khoom ntawm ib tus neeg lub cev kev sib hloov inertia thiab rotational tshaj tawm (hauv radians / sec) txog ib qho axis.

Ib yam li ntawd, angular tshaj tawm yog axial vector? Qhov no tso cai rau peb los txhais nws raws li qhov tseeb ceev yeej tsis muaj radial tivthaiv vim lub angularvelocity . Muaj ob hom vector . Ib qho yog polar, qhov thib ob yog axial . Angular tshaj tawm yog ib axialvector ua Yog li, tsis xav tau kev hloov pauv raws nws txoj kev.

Ib tug kuj yuav nug, yog angular momentum ib tug polar vector?

Angular zog yog tus ntoo khaub lig khoom ntawm adplacement (a polar vector ) thiab lub zog (polarvector ), thiab yog li ntawd yog ib tug pseudovector.

Dab tsi yog axial vector muab piv txwv?

Ib qho piv txwv ntawm ib axial vector yog cov vector khoom ntawm ob polar vectors , xws li L = r × p, qhov twg L yog lub angular momentum ntawm ib tug particle, r yog nws txoj hauj lwm vector , thiab p yog nws lub zog vector .sponsored los ntawm Factinate.
