SUMMARY
The kinetic energy of a rigid bar that is both rotating and translating can be expressed using the formula KE = (1/2)m(vC.M)2 + (1/2)(ω·LC.M), where m is the mass of the bar, vC.M is the velocity of the center of mass, ω is the rotational velocity, and LC.M is the angular momentum relative to the center of mass. This formula accounts for both translational and rotational kinetic energy components. Understanding these terms is crucial for analyzing the dynamics of systems involving rigid bodies in motion.
