WebThe term inertia, often used by scientists and engineers, is an analogy with that used in mechanics to relate mass and velocity, where inertia, in that case, is that which limits the acceleration of the object. Similarly, thermal inertia can be interpreted as a measure of the ‘thermal mass’ and the speed with which the heat wave is ... WebMoment of inertia, also called rotational inertia, mass moment of inertia, or polar moment of inertia of mass, is the mass property of a rigid body that determines the torque needed for a desired angular acceleration about an axis of rotation. ... In SI units, moment of inertia is measured in kilogram-square metres (kg•m2), and in imperial or ...
