Kinetic energy from moment of inertia
WebThe formula for rotational kinetic energy is. E = Iω²/2. where I is the moment of inertia. For a uniform disk, the moment of inertia. I = mr²/2. Putting it together. E = mr²ω²/4. Substituting actual numbers. E = 58.3×0.8²×5.4²/4 = 272 J. WebThe 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. Part of the Earth's rotational energy can also be tapped …
