The Physics Of Judo Essay

The Physics of Judo

Judo is a martial art that is centered around physics. Even just the concept of throwing somebody is physics. To practice judo and not have a basic knowledge of physics is insane considering that physics is what makes judo possible. Judo is sport that consist of throws, take downs and over all control. Judo without physics is like have a sandwich with just bread, you don’t get much out of it. To understand how physics comes into play with judo we must start with Newton’s laws of motion.

“Newton’s first law: law of inertia, a net or unbalanced force is needed to change the state of motion of and object. In a judo match, two players try to throw each other by first off-balancing the other player, the fitting their body into a position underneath their opponent for a throw, and finally throwing their opponent squarely on their back. The key to throwing the other player in the off-balance. Without first off-balancing your opponent, your chance of successfully completing a throw are slim. You’re also asking to be countered if you don’t off-balance first.”(1)

“The first law of motion is important if you want to successfully throw your opponent in a match. For instance, suppose your opponent makes a move to his right in order to make you move to you left. In the instance that you are moving, you’re temporarily off-balanced. Rather than letting your opponent keep control of the situation you and take advantage of his motion by using Newton’s first law. In this scenario, the statement “an object in motion will stay in motion” applies. As he is in motion you quickly turn into your opponent enabling you to lift him up with your hips and throw him.”(1)

“Newton’s second law: F=ma, the acceleration of a body is proportional to the net force on it and inversely proportion al to its mass. If you are in a match, facing an opponent who weighs less than you and you push him with a quick acceleration of the hand, you will have exerted a larger force on him then you would have if you had only pushed him with a smaller acceleration and chances are that he will move or fall easier for you. If, on the other hand, your opponent has more mass than you, the acceleration that you hit the smaller man with will have less force on the more massive man because acceleration is inversely proportional to his mass.

The faster you throw your opponent with, the larger the force that he falls with will hit the mat. If he is larger than you, then he will not need to exert as much acceleration on you in order to achieve the same amount of force a man smaller that yo would. So, what does this tell you? That you’d be better off...

The Physics of Boomerangs

1382 words - 6 pages The Physics of Boomerangs The successful flight of a boomerang looks as though it never should happen. Its more or less circular flight path comes from the interaction of two physical phenomena: the aerodynamic lift of the arms of the boomerang and the spinning boomerang’s maintenance of angular momentum. Briefly put, the airfoil at the boomerang’s forward rotating edge provides more lift than its rearward rotating edge. This elevates...

The Physics Of Football Essay

The Physics of Football

The crowd is cheering as the quarter back from the Chicago Bears throws the football 25 yards to the star wide receiver. As the wide receiver catches the football, he starts off on a mad dash to make a touch down. During his run for the touchdown, he does not see his opponent from the Dallas Cowboys sneaking up on him to stop his success. The wide receiver from the Chicago Bears is tackled by his opponent and prevents him from his victory. While watching this fascinating and suspenseful moment, one would not think that there is more to football than fun and excitement. Football is more than entertainment and a sport, it is an in depth lesson on physics. After learning about physics, a student will not be able to watch football without thinking about all the concepts of physics that are involved.

Timothy Gay, a professor of physics at the University of Nebraska, Lincoln (UNL) said, “Football is a manifestation of physics and it’s something people can relate to. It’s physics in action.” (The American Physical Society) Professor Gay has been using football to teach physics to his students at UNL, this has helped the students understand and love science.

There are many aspects of football that involves physics. When the ball is thrown, or kicked physics is being used. The players are using physics when they run down the field. Physics are also used when a person is tackled. The equipment that the players use to prevent injuries also uses physics. These simple but important parts of the game of football could not happen without physics.

When a quarterback throws the ball through the air, there are many things that he needs to do. For example, he needs to consider the speed at which he must throw the ball to get it to his teammate, he must also consider the distance that it must travel, and the wind speed and gravity must also be figured into how he will throw the ball. As the football travels through the air, it follows a parabolic path because it is thrown up in a vertical direction, and gravity pulls down on it. (Freudenrich 2) This is also known as projectile motion. “Projectile motion…occurs near the surface of the Earth when the only force acting on the object is that of gravity” (Kirkpatrick and Wheeler 70). As the ball travels down the parabolic path, the football accelerates until it hits the ground.

When the kicker punts the football, the kicker must consider many factors also. He must consider the speed of the football, the angle he kicks it, and the rotation. “The angle of a kick helps determine how far it will travel” (Freudenrich 2). The speed and distance or velocity of the football will be affected by the gravity, it will also be determined by the force that the football is kicked. The rotation of the ball will also affect the speed and distance of the kick. If the kicker kicks the ball so that it rotates end over end it will have more air drag (causing it to slow down), but if it is kicked in...
