       How Can

       Dynamics

       Be Applied

       to Judo?

      IF WE wish to carry a heavy load somewhere, we use certain required tools or machines to economize our energy and time. For instance, if we are putting a large stone on a truck, by leaning a plane surface against the truck and making the stone roll or slide along it we can easily do the work, economizing our energy and, in the end, our time. This is taking advantage of both the law of resolution of forces and the law of friction, and if, in addition, we use a lever, we can do the work even more easily. This is taking advantage of the law of moment. We can make the stone roll or turn over to the right or left at will by taking advantage of dynamics. But how about the human body? A human body has a nervous system, so it can perceive your intention and make motions at its own will.
