10.6: Calculating Moments of Inertia - Physics LibreTexts

WebAn example is the calculation of the rotational kinetic energy of the Earth. As the Earth has a sidereal rotation period of 23.93 hours, it has an angular velocity of 7.29 × 10 −5 rad·s −1. The Earth has a moment of inertia, I = 8.04 × 10 37 kg·m 2. Therefore, it has a rotational kinetic energy of 2.14 × 10 29 J. WebThe moment of inertia is always defined with respect to a specific axis of rotation. Expressed as either a discrete sum or integral over a continuous distribution of mass, moment of inertia is given by.
