Laws of Physics Behind Aikido - Research Paper Example

Laws of Physics behind Aikido Laws of Physics behind Aikido Aikido refers to a Japanese form of martial arts that was developed byMorihei Ueshiba as a fusion of his philosophy, martial studies, as well as religious beliefs. It is normally translated as the method of unifying life energy and/or as the method of unifying harmonious spirit (Mroczkowski, 2012). This comprises a set of holds and throws that are aimed at subduing and controlling an uke without permanently injuring them. The creator’s aim was to develop an art, which people could apply to protect themselves whereas keeping their attacker from injury, as well. Aikido methods comprise of entering and turning movements, which readdress the force or energy of an opponents attack, and a joint or throw lock that ceases the technique (Mroczkowski, 2012). Even though, it derives largely from the martial arts of Daitō-ryū Aiki-jūjutsu, it started to deviate from it in the late 20s, partially because of Ueshibas association to the Ōmoto-kyō religious conviction. His initial students writings have the phrase aiki-jūjutsu (Mroczkowski, 2012). However, his senior students have unique approaches to the fighting method, relying partially on when they learnt with him. Today, the style is seen all over the world in countless methods, with a couple of interpretation and stress. Nevertheless, they all share methods that were developed by Ueshiba and a majority have apprehension for the safety of the attacker. Because the technique involves force and reaction, physics is normally involved when it comes to the execution of its techniques. This paper will discuss the laws of physics behind Aikido and how things like force, momentum, rotational speed, direction, impulse and conservation of energy can work for or against a person. Similar to Judo, Aikido is a form of martial arts, which demands an intuitive comprehension of the physics of forces, stability, torques plus rotational motion (Mroczkowski, 2012). The grace that each needs is not simply conveyed, but each and every method can be split into components, which can be assessed in reference to classical physics. Aikido seeks to surmount a rival’s stability. It is a fairly modern type of martial art, which integrates methods from a couple of other martial art methods. It is differentiated by its firm code of making sure that you do not injury the opponent. Thus, it is mainly a type of self-defense when compared to other martial arts methods such as judo (Mroczkowski, 2012). It incorporates no methods, which can be deemed as attacks and many critics have deemed it as the hardest martial arts form to learn. It calls for great skills, timing and grace in order to produce a classical ballet with your opponent. The technique makes use of a lot of the similar techniques found in different martial arts forms such as Judo. Imagine your attacker holds you by the hand (left or right) from behind; in one aikido tactic you easily lower your body whereas raising your hand upward and over your head to the front. Your attacker hangs on to your hands, but is brought in front by your slick and slight bend forward. Therefore, his or her position is uneven since his or her center of gravity is now somewhat forward of his feet (Mroczkowski, 2012). You then draw your right foot backward and drop down onto your knee. Your torso and arms are now brought downward and forward in a large arc. Since the initial part of the motion made your attacker to hold firmly to your wrists, he or she is now tossed over your body in a front flip. In aikido, your attacker always throws himself or herself towards you. This makes it hard for him or her to prevent your forward motion due to the unbalanced position in which you at first placed him or her. Even though, he or she has greater body mass, they cannot terminate the motion through pulling down on your raised hands. In such a situation, the attacker can only pull along the length of your hands. The torque that results because of such a pull is zero since there is no “lever” (Mroczkowski, 2012). Bear in mind that the lever is the perpendicular from the pivot point to the line through the force, which, in this case, is your shoulder (Mroczkowski, 2012). The line through the attacker’s pull passes by your shoulder and; thus, lacks a lever arm. Even though, the attacker is strong or heavy, he or she cannot turn your hands once you have them appropriately over your head. A number of the methods in aikido use the deflection of a force applied towards you. Imagine your opponent throws a blow at your face. To stop this attack directly needs a larger force that might lead to injury of both the parties. A better method is to deflect the punch. Even though, greater force is needed to halt the punch directly, just a small amount of force is required to deflect it (Mroczkowski, 2012). Even though, a majority of the followers of Western style of fighting regard an assault to be an advantage to them to the attacker, in aikido the one carrying out the assault is at a distinct disadvantage due to the force of this strike. This is because the person being attacked can use his or her momentum to throw the attacker to the ground (Mroczkowski, 2012). Imagine that your attacker steps forward with his or her left foot and hits at your head with the side of his or her left arm. In aikido, you are supposed to slide your right foot to the rear as you ward off his attack with your right hand. The ward off is meant to deflect the attack, not to slow it or even to stop it, because either impact would need strength and force from you, which will work against you. During the ward off, you guide your opponent’s left hand downward into the grip of your right arm (Mroczkowski, 2012). Whereas still not combating the forward drive of his or her punch, you pull the attacker around in the round motion you have started with the pulling out of your left foot in order to avoid harm. The defender, through moving out of the line of the assault alters the direction of the opponent’s motion to curvilinear from rectilinear. He or she attempts to travel on the least possible curve. If the opponent moves in the similar manner as the defender, then he or she moreover adds centrifugal force. If the two weights are joined by, for instance, carrying out a grip by just one of them, then the 2nd principle of dynamics applies here (Mroczkowski, 2012). The person being attacked, along with declining the curvilinear motion radius, is reducing the moment of inertia of the two fighters. He or she attempts to move in such a manner as to make sure that at the end of stunt, the axis of motion rotation is perhaps the nearest to his or her body. When conducting a certain method, aikido fighters are fighting with particular forces, and because it is a curvilinear motion, a resultant motion of force is created. This moment of force, with dropping the motion of inertia of the fighters, leads to a raise in the angular acceleration in this movement. The moment of inertia will be the sum of the moments of inertia of both the fighters (Mroczkowski, 2012). For this reason, their central moments of inertia and the distances from their centers of mass have to be determined. When the attacker’s radius reduces, the angular velocity of the fighters’ bodies goes up and their moment of inertia of the position gets smaller. If we do not take into consideration the motion resistance, then we can discuss the principle of the conservation of the moment of momentum. The fighters behave in the same way to figure skaters when carrying out a pirouette. In this manner, they put their lower limbs near the axis of rotation, which increases their angular velocity (Mroczkowski, 2012). During the motion, the centre of gravity of the defender will be at the nearest possible distance from the rotation axis of the fighters’ bodies’ arrangement. Your hands will be as close to this axis as possible. This decreases the moment of inertia of the fighters and increases the amount of the centrifugal force of the attacker. The centrifugal force grows bigger when the speed the rival attacks with rises, his weight goes up plus the radius he or she tracks gets smaller. The actions of the attacker can be contrasted to the behavior of a vehicle on a bend of the road; the smaller the radius and the sharper the bend, the bigger the vehicle speed, as well as the force acting on the vehicle, raising the risk of the car tumbling off the track. The actions of the defender can be compared to the motion of a spinning top (Mroczkowski, 2012). The external force that is acting on the spinner cannot, by any means, disturb its rotational movement. Thus, the defender produces a move that causes the attacker to gain more centrifugal force. Thus, he or she acts stepping out of the line of the assault in a manner that entire motion is carried out around the axis of rotation going through his body. The centrifugal force might lead to neutralizing the attack, but it is normally adequate to knock the opponent over. So as to conduct a throw, the defender utilizes his or her weight, which when sufficiently transferred might be more than the centrifugal force acquired by the attacker (Mroczkowski, 2012). Thus, in many methods, the defender unexpectedly lowers his or her centre of gravity so as to raise the technique dynamics. In the last phase of the throw, provided the attacker’s body is inclined enough, so as not to meet his surprising counter-punch, the person being attacked is even more likely to perform a one leg jump. When carried out perfectly it eases the shift of the defender‘s mass down. Then all his or her P=mg is utilized in the fight. Most often, the force allow an aikido throw is due to the centrifugal force of the person attacking and the weight of the defender (Mroczkowski, 2012). A proper case showcasing the actions of the defending individual would be a rotating top, which apart from a spinning motion would also do an up movement for instance jumps. In conclusion, Aikido has hundreds of method for using such trickery against an opponent. In almost all of them, a small deflection of force wards off an opponent’s thrust plus then guides it so that he or she throws themselves down. When you watch an aikido fighter defend themselves, the motion appears effortless and fluid, and you are inclined to think the opponent is faking the fall. However, the fall is not imitated. It appears that way since the fighters has spent years developing the fight. Reference Mroczkowski, A. (2012). Using the knowledge of biomechanics in teaching aikido.
