Ib yam li ntawd, angular momentum derivation yog dab tsi?

Lub orbital angular zog ntawm ib yam khoom hais txog ib lub hauv paus chiv keeb xaiv yog txhais raws li tus angular zog ntawm qhov chaw ntawm huab hwm coj txog keeb kwm. Tag nrho angular zog ntawm ib qho khoom yog qhov sib npaug ntawm qhov sib tw thiab orbital lub kaum sab xis lub sijhawm. Torque tuaj yeem txhais tau tias yog tus nqi hloov ntawm angular zog , analogous rau quab yuam.

Tom qab ntawd, lo lus nug yog, yuav ua li cas angular momentum txawv ntawm linear momentum? Linear zog yog huab hwm coj multiplied los ntawm kev tshaj tawm, yog li nws ua raws li ntawd angular zog yog lub sijhawm ntawm inertia, ntsuas hauv kilometer squared, muab faib los ntawm lub kaum sab xis ceev, ntsuas nyob rau hauv radians ib ob.

Ib yam li ntawd, angular momentum txhais li cas?

Angular Momentum . Cov angular zog ntawm ib yam khoom rigid yog txhais raws li cov khoom ntawm lub caij ntawm inertia thiab lub lub kaum sab xis ceev. Nws yog analogous rau linear lub zog thiab yog nyob rau hauv lub hauv paus kev txwv ntawm kev txuag ntawm angular zog txoj cai yog tsis muaj torque sab nraud ntawm cov khoom.

SI unit ntawm angular momentum yog dab tsi?

Tsim nyog MKS los yog SI units rau angular zog yog kilometer squared ib ob (kg-m2/sec).
