Cov kev hloov counterpart rau pawg yog kev sib hloov inertia lub sij hawm ntawm inertia . - Ib yam li huab hwm coj sawv cev rau qhov tsis kam mus rau qhov kev hloov pauv hauv cov lus tsa suab, kev sib hloov inertia yog qhov tsis kam ntawm ib yam khoom los hloov hauv nws kev hloov tsab ntawv tsa suab. - Kev sib hloov inertia muaj feem xyuam rau qhov loj ntawm cov khoom.

Kuj paub yog, txoj cai ntawm kev sib hloov yog dab tsi?

Newton thib ob Txoj cai rau Kev sib hloov . Yog tias ntau tshaj ib lub torque ua rau lub cev nruj ntawm lub axis ruaj khov, ces qhov sib npaug ntawm cov torques sib npaug ntawm lub sijhawm inertia lub sij hawm lub angular acceleration: Nco ntsoov lub convention uas counterclockwise angular acceleration yog zoo.

Dab tsi yog qhov rotational inertia nyob ntawm? Rotational inertia nyob ntawm ob qho tib si ntawm ib qho khoom loj thiab qhov loj npaum li cas faib txheeb ze rau lub axis ntawm kev sib hloov . Tsis zoo li lwm yam xwm txheej hauv physics uas peb ua kom yooj yim cov xwm txheej los ntawm kev ua txuj tias peb muaj qhov taw tes loj, cov duab ntawm ib qho khoom txiav txim siab nws. kev sib hloov inertia.

Hauv qhov no, txhais li cas los ntawm kev sib hloov inertia?

Kev sib hloov inertia yog ib tug scalar, tsis yog ib tug vector thiab yog nyob ntawm lub vojvoog ntawm kev sib hloov raws li tus qauv kev sib hloov inertia = mass x radius^2. kev sib hloov inertia . Kev sib hloov inertia , kev sib hloov inertia yog qhov ntsuas ntawm ib yam khoom tsis kam hloov hauv nws kev sib hloov.

Newton Txoj Cai thib 2 yog dab tsi hauv daim ntawv hloov pauv?

Rotational Form ntawm Newton Txoj Cai Thib Ob . Cov daim ntawv hloov ntawm Newton txoj cai thib ob hais txog kev sib raug zoo ntawm net sab nraud torque thiab lub angular acceleration ntawm lub cev txog ib tug axis ruaj. Qhov tshwm sim zoo ib yam li Newton txoj cai thib ob nyob rau hauv linear tsab ntawv tsa suab nrog ob peb kev hloov kho.
