WebApr 7, 2024 · Solution. Earth’s radius = 6.37 × 106 m. Mass of Earth = 5.97 × 1024 kg. We need to first find the moment of inertia to calculate rotational kinetic energy. Considering the shape of the Earth as a sphere we get: Moment of inertia I of Earth = ⅖ * m * r2 = ⅖ * (5.97 × 1024 kg * (6.37 × 106 m)2) = 9.69 * 1037 Kg.m2. justice gethin edwardWebLooking at the equation: Kr = (1/2) * m * r^2 * ω^2. Without the summation portion this is the rotational kinetic energy of a small piece of the object. The term r is not the radius of the whole object.
