WebMoment of inertia is the rotational analogue of mass for a rigid body rotating about a given axis. It takes account of how the body's mass is distributed (since for a rotating body different parts have different linear velocities and accelerations). http://labman.phys.utk.edu/phys135core/modules/m8/energy.html

Web1 aug. 2024 · Solution 1. Because the moment of inertia for a point mass is: I = m r 2. When calculating the moment of inertia for continuous bodies we use calculus to build them up from infinitesimal mass elements, so effectively to calculate the moment of inertia of the disk (without hole) we're doing: I d i s k = ∑ i d i s k m i r 2. WebThe moments of inertia, however, are all different, so their rotational accelerations (and, thus, also their linear accelerations) are different.
