Theorem 4 (Reduction by symmetry — Euler–Poincaré) If L is invariant under a Lie group G action, then dynamics reduce to the Lie algebra via the Euler–Poincaré equations. For rigid body with G = SO(3), reduced equations are Euler's equations. (Proof: Section 7.)

Theorem 1 (Newton–Euler Equations, body frame) Let a rigid body of mass m and inertia I (in body frame) move in space under external force F_ext and moment M_ext expressed in body coordinates. The equations of motion in body frame are: m (v̇ + ω × v) = F_body I ω̇ + ω × I ω = M_body where v is body-frame linear velocity of the center of mass, ω is body angular velocity. (Proof: Section 3.)
