science in judo

According to Newton's second law of motion, you have an advantage over your opponent when your body is larger than his. Besides that law, however, there is another factor that gives you advantage over a smaller opponent. This is the large muscular force with which a big man is usually gifted. He can carry a heavy block or lift it easily, whereas the same feat may be difficult for a smaller man. Although we can say that large muscular force is very convenient for breaking the opponent's posture in judo, muscular force alone does not encompass all the forces used in judo.
