Taking a walk? It is “ordinary force”!

Taking a walk is “ordinary” force

It occurs to me that "Ordinary Force" is also built into our everyday leg movement, all 7 billion of us. A familiar "Ordinary Force" example to explain Newton's third law of motion is the walking of a person on the ground. I say “explain” because Newton’s Laws are not intuitive and if they were, then excuse my wishful thinking, but so many more people might well have “internal discipline”.   When a person walks on the ground, then the person exerts a force in the backward direction. However, as you see in the video by Master Stephen Hwa, there is a "backward" direction from an ordinary force arm push. This force applied is known as action. 

In walking, kicking, etc., as a result of this force applied, an equal and opposite force is used by the ground to the other foot, and this force helps to move, kick, etc., in the forward direction. This force is called the reaction force. When you walk and are not using internal discipline, it is an ordinary force. When you do a Karate kick above the waist, your Wing Chun kick to the shin, etc., it is a force. 

I did Tae Kwon do for years, and take my word for it seemed like 99% kicking. A typical incident was seeing novices kick a heavy bag with an above-the-waist kick and then are knocked backward. Of course, students in any art get better, but it is nowhere near the martial, internal skill, and "core" dexterity of a proficient student of Classical Tai Chi.
