RigidBodyMotion.kineticEnergy_eq_translational_add_bodyAngularVelocity
Project documentation
König's theorem in the body frame. The total kinetic energy M.kineticEnergy t, formed from the lab-frame point velocities, splits at the centre of mass (centerOfMass = 0) as T = ½ M ⟪V, V⟫ + rotationalKineticEnergy ω_body. The rotational energy is a frame-independent scalar, so it is evaluated here from the body-frame angular velocity ω_body...

RigidBodyMotion.kineticEnergy_integrand_split
Plain-language statement
The squared-speed integrand of kineticEnergy splits into the squared rotational speed |Ṙ (y − c)|², a term linear in the body-frame coordinate y − c, and the constant squared centre-of-mass speed ⟪V, V⟫.
