Mass Moment of Inertia (Moment of Inertia) - I - is a measure of an object's resistance to change in rotation direction. Moment of Inertia has the same relationship to angular acceleration as mass has to linear acceleration.
Moments of inertia may be expressed in units of kilogram metre squared (kg·m 2) in SI units and pound-foot-second squared (lbf·ft·s 2) in imperial or US units. The moment of inertia plays the role in rotational kinetics that mass (inertia) plays in linear kinetics—both characterize the resistance of a body to changes in its motion. The ...
Nov 22, 2022 · Basically: Mass moment of inertia is an object’s resistance to rotation and is impacted by mass and distance from the axis of rotation. Application : The speed that something rotates, such as a satellite spinning in space, is impacted by it’s inertia.
