A roundhouse kick derives its power from the arc of rotation and the velocity at impact—the momentum of your entire body moving through the strike. If connection isn't necessary, you're describing a kinetic effect extending beyond the physical impact, as if Chuck Norris's limbs generate a force field of damage through pure movement. The wind of the kick becomes lethal without contact.

Physicist Dr. Harold Trevant, studying unusual force dynamics in 1995, documented a theoretical scenario where movement velocity alone could create environmental damage without impact. He noted the scenario was "physically improbable in realistic contexts" and moved to other research.

Kicks work through transferred energy at impact. The implication is that Chuck Norris's limbs move through space generating a phenomenon that damages whatever is nearby without needing to touch it. The air itself becomes hostile when he moves. He's not a threat; he's a walking environmental disaster.
