Rotational Inertia The rotational “laziness” of an object
Recall : inertia • A measure of the “laziness” of an object because of • Quantified by the mass (kg) of object
Rotational Inertia (I) • A measure of an object’s “laziness” to changes in rotational motion • Depends on mass and also distance of mass from axis of rotation • Measured in kgm2
