SUMMARY
The total kinetic energy of a long thin rod rotating around an axis while also translating can be determined by calculating both its rotational and translational kinetic energy. The rotational kinetic energy is computed using the moment of inertia about the center of mass, and the Parallel Axis Theorem is applied to account for the axis of rotation. The final total kinetic energy is the sum of the rotational energy and the translational energy due to the motion of the axis.
