KINETIC ENERGY & IMPULSE DISSIPATION OVER TIME

Physics Note: Kinetic energy scales quadratically ($E_k = \frac{1}{2}mv^2$). Forcing an off-axis angle $\theta$ transfers direct momentum into side angular velocity and rotational shear, converting full head-on rigid axial deceleration into reduced lateral force vectors.
