Cov tswv yim yooj yim ntawm inertia
Qhov xwm ntawm yam khoom uas tseem nyob ruaj ruaj lossis hauv cov tsoos txawv teeb tsa suab lub xeev yog hu ua inertia. Inertia yog qhov khoom ntiag tug ntawm qhov khoom. Nws yog qhia raws li qhov kev kawm ntawv ntawm impedance ntawm ib qho khoom rau nws cov lus tsa suab lub xeev. Kev ua tau zoo yog ntsuas ntawm lub zog ntawm qhov khoom. Thaum lub zog sab nraud ua rau qhov khoom yog xoom, qhov tsis muaj tseeb yog qhia raws li qhov khoom cia nws cov lus tsa suab tsis hloov, uas yog, nws tseem nyob ruaj ruaj lossis teeb ua suab ntawm qhov ceev ib txwm; thaum lub zog sab nraud ua yeeb yam ntawm qhov khoom tsis yog xoom, qhov tsis muaj tseeb tshwm li lub zog sab nraud los hloov qhov kev hloov chaw ntawm lub zog. Theem nyuaj. Hauv tib lub zog sab nraud, qhov loj ntawm qhov khoom nrog qhov nrawm me dua, thiab qhov tsis muaj zog ntawm qhov khoom nrog qhov nce loj dua yog qhov me dua. Yog li no, qhov tsis txaus ntseeg ntawm ib qho khoom yuav tsis hloov lub sijhawm twg (los ntawm lub zog lossis sab nraud los ntawm sab nraud), thiab yuav tsis hloov nyob rau hauv ib qho xwm txheej twg (tseem lossis txav). Inertia yog tus cwj pwm ntawm teeb meem nws tus kheej.
