# Soccer: Geometry of Goal-Scoring

770 Words4 Pages
The adult soccer goal is 24 feet long by 8 feet high, and the penalty shot, which is the shot I will be using in order to keep a constant spot, is 12 yards away from the back of the goal. The independent factors of the experiment are the different angles of the shot. Dependent factors would be the number of goals scored. The controls of the experiment are the size of the goal, soccer ball type, soccer ball size and weight, temp in the gym, kicking surface, and the method of measurement. Variables that will affect the experiment are force, speed, velocity, and most importantly, experience. Soccer is played in over 200 countries over the world, making it the most popular sport. Over one billion fans watch the World Cup Soccer on television, which is played every four years. Soccer players run an average of six miles during every game. The United States and Canada are the only two countries that call it soccer. The first soccer games may have originated in China. The U.S has more official soccer players than any other nation in the world, almost 18 million. The first women’s soccer team, called the Women’s United Soccer Association (WUSA), made its first debut in 2001. Soccer is a game that is played a lot on angles and measurements. Most wouldn’t think that angles come into play when playing soccer, they just kick it into the goal wherever they can. To make a good, precise shot, you must take into account where you are in relation to the goal, and decide what angle would be the best to aim and kick for. Where the kicker is standing in correlation to the goal plays a major factor on the difficulty of the shot. Also, if the kicker is a left or right footed kicker and what side of the goal they are on also plays an important factor... ... middle of paper ... ...distance, height, and most importantly, angles. The main thing I will be looking for in my experiment is how much angles play a role in goal scoring and where they come into play the most. Using all of the information I have found about how to kick, the proper distance away from the goal when kicking a foul shot, and the correct dimensions of the goal, I will conduct an experiment with results that are as close to a real soccer game as possible. I will not be using defenders that way I can get a better measurement of the angles I am kicking from.
