Moment ntawm inertia txhais
Lub sij hawm ntawm Inertia yog qhov ntsuas ntawm lub inertia (tus xeeb ceem hais tias cov khoom sib hloov tau tuav nws txoj kev sib luag ntawm txoj kev txav los yog so) thaum lub cev tsis sib dhos tig puag ncig ntawm lub axis, thiab sawv cev los ntawm tsab ntawv I lossis J. [1] Hauv cov neeg kho tshuab thaum ub. , lub sijhawm ntawm inertia (tseem hu ua pawg caij ntawm inertia, hu ua lub sijhawm ntawm inertia) feem ntau yog qhia raws li kuv lossis J, thiab SI chav tsev yog kg · m2. Txog qhov me me, I = mr2, nyob qhov twg m yog nws qhov loj thiab r yog qhov nrug ntawm ib feem thiab cov axis ntawm kev sib hloov.
