Physics of Karate Essay -- physics martial arts fighting

The basic ideas behind any(prenominal) style of karate can in general be reduced to the culture of achieving the more or less effective movements with the least effort. Specifically, with a strike such as a punch, kick, knife-hand or similar, the karateka attempts to move swimmingly through the strikes, conserving energy towards the encroachment point. When thought about in terms of energy, the most common comparison is that of rotational kinetic energy, or KE=(1/2)mv2 + (1/2)I2. Another way to call in about a strike is to attempt to focus as oftentimes force as possible at the point of impact. In many another(prenominal) strikes, this is facilitated by drawing an almost straight line with the striking son of a bitch from the original point of rest to the point of impact. This is based on the event that the fastest path between two points is a direct line, and greater speed leads to corresponding greater force upon impact, as shown by Newtons blurb Law, F=ma. This equation also leads to the conclusion that if increased mass is employ in the strike, the force upon impact will be greater. Because of the obviousness of this idea, most strikes are thrown through the rotation of the body in roughly way, instead of simply from the arms or legs. The body has much more mass, and therefore contributes greatly to achieving a strike that is highly forceful, yet doesnt posit nearly as much effort as one thrown from the extremeties. Front StanceEquationsW=mg=I=Fr clangoring F=N The most basic part of a succesful proficiency is a proper stance that is well grounded and unfluctuating. This helps in many ways, including providing the initial push behind a technique, grounding the karateka during the moment of impact, and providing a solid base from which to defend against an attacker.... ...rown into the rotation, the more energy is contained in the leg at this stage in the kick. The next stage of the kick switches to up and frontwards rotatio n of the knee around the hip joint. This is also connected to the equations v=r and KE=(1/2)mv2 + (1/2)I2, thus KE=(1/2)m(r)2 + (1/2)I2. In a justly executed kick, this transition is completely smooth, and energy is conserved. This leads to the idea that a brisk part of a proper, focused front kick is how quickly and smoothly the back leg is pulled forward. The last step in the kick is the upwards rotation of the foot around the knee joint, the kinetic energy of which is order through exactly the same equations. To ensure that the energy is expended on forward impact rather than upwards, during the rotation around the knee, the hip should be encompassing forward slightly just before impact.
