This week's Aiki-theme is rebound theory. Yes part of Aikido is in fact based on physics. Aikido is often primitively defined as using the opponent's force to your advantage. However there is more to it than that. How one can use the force if no force is given and how the force is therefore initiated have to be investigated. In physics one can define a rebound as follows: Occasionally when objects collide, they bounce off each other as opposed to sticking to each other and traveling with the same speed after the collision. Bouncing off each other is known as rebounding. Rebounding involves a change in the direction of an object; the before- and after-collision direction is different. Based on this definition, the effect of "using the opponent's force" has to be applied in the context of first applying a rebound to initiate the force of the opponent. It is not a matter of sitting and waiting for the force to arise. Tori has to make a conscious attack from a connecting point to trigger the response and thereby initiate the force of Uke. It is notable that, while the collision creates a potential separation, it is in fact the Tori's job to unite with the movement of Uke thereby creating not a separation from Uke but rather a separation from the ground as Uke attempts to regain balance consequential to surrendring his or her balance. It sounds all scientific but these words will make sense after practicing a while to not leave the hand of Uke and to always seek for the collision in order for the rebound to arise. Not easy but it's a lot of fun trying to achieve that.
