A simplified formula for energy conservation looks like this: E input = 1/2mv² + 1/2Iw² + E dissipated Where: m = Mass of the helmet system v = Resulting linear velocity I = Moment of inertia of the helmet w = Angular velocity of the helmet E dissipated = Energy dissipated by the helmet's padding Lab tests are scored based on the measured impact severity which is tied to the kinetic response of the head form
