Dr. Dimakis, involved in the martial art Aikido, does a demonstration of the physics involved. Aikido, the Japanese martial art, is distinguished by it's goal to defend while protecting the attacker from injury. Aikido deals with a blending of motions as well as redirecting of forces from the attacker which ultimately results in the expense of very little physical energy. In the video, you will be able to see bodies in motion and hear descriptions from Dr. Dimakis of what is taking place in terms of physics.
