Symmetry In Soccer

Soccer is called football in most of the world. It is considered to be the world's most popular sport. In soccer there are two teams of eleven players. Soccer is played on a large grass field with a goal at each end. The object of the game is to get the soccer ball into the opposing team's goal. The key to soccer is that players cannot touch the ball with their hands, they can only kick, knee, or head the ball to advance it or score a goal, with the exception of the goalie. Goalie can use all body to protect the goal. In soccer, it has red and yellow cards to punish players who have fouls, and it has many rules. I know quite a lot but still a lot of things in soccer I do not know yet.

Most people would assume that soccer is the fastest game played with two feet, but actually it is lacrosse. Math is used in the game of lacrosse in many ways, as an example the angle you shoot at determines where the ball goes. Also, an example of math being used would be the different shapes in the game. Like for example, the field you play on is a rectangle with different shapes and lines to determine the foul lines, shooting lines, and the half-field. Another subject of math being involved in lacrosse is the area inside the net. This is how much space there is in the net, where the ball could go.

Also in hockey there needs to be a rink of ice and you need skates, a stick, pads, gloves, a helmet and proper attire. Soccer is a convenient sport because in order to play all you need is a couple of friends, a ball, and 2 nets or 2 posts. Soccer can be played on turf ground, a grass field or even on the streets. Many other sports need a defined amount of area to play in such as golf or an ice rink such as hockey or dirt ground with bases and a fence such as baseball. For soccer it can be played almost anywhere including the park, your driveway or the parking

If you play soccer, you have to practice in order to win, just like any other sport. When playing a game, you need to do moves that you have practiced, to get past the other teams defense and score a goal, and you also have to teach yourself mentally to think before you react. If you have the ball, you can’t just kick it randomly and hope to score, you have to think of your other teammates and work with them to get the ball up the field. Another part of soccer that is very critical is passing. You have to pass the ball and develop new techniques and ways to control how the game is played.

In soccer there are many rules that have changed. Back in the 1700's the playing field was shaped like a square. There were only four major markings on the field. They were the touchlines, goal lines, halfway line, and the eighteen-yard lines. When the Football Association (FA) was created in 1863, the first uniform rules were made. FIFA now requires that soccer be played on a rectangular field between one hundred and one hundred-thirty yards long and between fifty and one hundred yards wide. For international matches the field should be between one hundred- ten and one hundred-twenty yards long and between seventy and eighty yards wide. There are two goals, one placed at each end of the field. They are eight feet tall, eight yards across, and six feet deep. The lines that mark the sides of the field are called touchlines; those that mark the two ends of the field are called goal lines. Also there are five other distinctive lines. They are the halfway lines, the goal areas, the penalty areas, the corner marks, and the center circle.

The physics involved in soccer includes friction, torque, center of gravity, Magnus Effect and Newton’s three laws of motion. The physics of soccer comes from three main parts of physics which is velocity, acceleration, and displacement. Velocity is shown in soccer with the speed and direction of the soccer ball when it is hit or kicked. Acceleration is shown in soccer when the ball changes velocity when it is hit or kicked. Displacement is the change in position of the soccer ball.

Athletes who play football share the same goal as athletes who play soccer: score the most goals to win the game. In football, there are two areas on opposite sides of the field where one can score points by bringing the football over the goal line. Soccer shares this same concept by having two nets on opposite sides of the field where one can score a point by kicking the soccer ball into the net. Also, both sports share the concept of having an offense and defense, and both sports each have eleven players on a team on the field at a time. These are only few of many similarities between these two sports, but in actuality, they are significantly different. The rules, rituals, and concepts of both sports distinguish

Lawn Bowling, also known as Bowls, influenced today’s modern sport called Bocce Ball. Bowls originated from the Romans and “Descended from the universal pastime of throwing rocks or pebbles at targets on the ground” (Leibs 73). By the beginning of the Renaissance, this sport was popular among all classes of society. Some popular equipment that was used in the game was weighted balls, the jack, and the Trigg. Each player had four wooden balls, with a

The rules of play for soccer have deliberately been kept simple. The referee makes most of the decisions, and attempts to encourage fair play. The game starts off with a kick off, and the teams are allowed to pass, dribble, juggle, head, kick, and shoot the ball to place it down the field, and (hopefully, or eventually) into their opponent’s goal. If the ball is kicked off the field over the length of the field, the other team is given a throw-in, where the ball is thrown over the player’s head, and back onto the field. If the ball is kicked over the goal, or across the width of the field, either a corner kick results (by the offensive team, where the ball is placed on the corner of the field and kicked into play) or the defensive team is awarded a goal kick, where the ball is placed on the corner of the goal box, and kicked back into play. If a goal is scored, the ball is taken back to the center of

The short edges are the touch lines whereas the shorter lines are referred to as goal lines. A half line runs across the centre of the field dividing it into two equal parts. All these must be marked as well as the goal areas, centre circle, penalty area and corner arcs with a flag on each corner. The acceptable dimensions of a football field are 90-120meters length by 45-90meters width. The equipment that is needed for a football game is two goals, and a football. The players must wear shin pads and the correct footwear. A goalkeeper would wear gloves. The clothing that the players will wear is full kit which includes a shirt, shorts and socks. The length of game is two forty five minute halves with a short break in between. At the end of the ninety minutes extra time is added. If there is still no winner then the game goes into extra time which consists of two fifteen minute halves. By the end of this if there is still no winner then the game goes to penalty kicks.

Football uses a lot of mathematics, just from watching a game I can realize which are the strategies each team uses and the mathematical models they create to calculate at which point they need to be so they can score a touchdown, the time that passes, how they keep track of the score, and how many yards they are away from scoring a touchdown, to know all that information you need to use the math’s. For starters, the football field is a rectangular shape that is divided into several yards, each of these yards measuring a certain amount, that helps keep track of each team´s score and helps them plan their next move, each team has its own strategies and its own calculations they make so they can know and visualize how far away they are from scoring or from which point they need to pass the ball or catch the ball so they can score. That

Soccer (Football) is the most popular and fastest growing sport in the world. Over 240 million people play it regularly around the world. However, most people only get to view one side of soccer in their lifetime. They never get a glimpse of it in any other setting. For many people soccer is a very competitive organized sport. For others it is an everyday, fun activity. In some countries, soccer is their life, while in others it is just a sport. For those of you that don’t know, soccer is a sport where the objective is to score goals by kicking a ball into the other teams goal. It is a mix of offense and defense, with very fast paced action. You are allowed to use any body part except your hands and elbows. Soccers first appearance traces back to 3000 years ago in ancient China. But, the first modern version of soccer originates from Victorian England. Since then, soccer has spread around the world to the point where almost every country plays some form of it. I am going to address how it is different around the world and the reasons for this.

Soccer has to be played with eleven players on each side of the field if playing internationally or a tournament, there can not be more or less players on the team(“Soccer Field”). The soccer match is only played for a time period of ninety minutes. The ninety minutes is divided into two halves, each half is 45 minutes. The game can also go to extra time if the team ties the match(“Soccer

The distance that you are able to kick the ball can be summed up with the equation for distance, d=RT, distance equals rate multiplied by the time. So speed and time are both very important when kicking the ball because it directly affects the distance. Soccer players vary the distances that they want to kick the ball. Skilled players can estimate very quickly how fast to make the ball move to make it go where they need it to. Before learning this equation in physics I just thought you kicked the ball, but now I know that when this equation is applied to soccer it means so much more. Soccer players can use this to help them judge how hard and fast they need to be able to kick the ball to make it go a certain distance. This is just another example of how physics, the small details, can be used to improve ones soccer skills.

There is no question that everything people do in their lives involves physics. This is true from the way we communicate to the way that we fight wars. In some cases the influence of the laws of physics on our world are extremely apparent, such as in sports. Basketball, hockey, baseball and even cricket involve physics. From the most basic motions players perform in the game, to different plays designed by coaches, physics touches it all. These appearances of physics in the games that we play are sometimes so subtle we don’t even notice them. In other cases however, the impact of physics can be heard across the stadium as Jerome “The Bus” Bettis barrels his way into the endzone. The influences of physics on
