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.
