What is physical signifiacane of moment of inertia |
| Answer» Moment of inertia plays the same role as is played by mass in translatory motion. In translatory motion, mass is a measure of inertia, therefore, moment of inertia is a measure of rotational inertia in rotatory motion.Moment of inertia is a measure of how difficult it is to rotate a particular body about a given axis. significance: Greater the mass concentrated away from the axis, greater the moment of inertia. | |
