Rotational Kinetic Energy: The Twin of ½mv²
A flywheel bolted to an axle never travels an inch — and it can still power a bus. Meet kinetic energy’s rotational twin, K = ½Iω²: swap the moment of inertia I for mass and the angular speed ω for speed, keep the ½ and the square, and pick the right I for the shape.
