David Tarry IB Math SL 11/2/2014 Math Behind Penalty Kicks In soccer, the penalty kick is a golden opportunity for the shooter to attain a goal. The kicker is unchallenged by any opposing player except the goalkeeper who stands on the goal-line 12 yards away. This one on one situation allows the player shooting to have a great advantage over the goalkeeper. Using the opportunity to the team’s advantage is of real importance due to the fact that in most instances they determine the outcome of games. This paper analyzes the variables involved in a penalty kick and maps out the best methods to use to ensure a very high success rate. The two fundamental components of a penalty shot are the angle at which the shot is kicked and the velocity of …show more content…
Best region to allow for error on the ground. At this point we have only considered the best shot on the ground. Considering the best shot in the air, ideally the ball would be placed right under the cross bar. FIGURE 3. Best region for a Penalty in the air with error margin. However, when deciding to kick the ball in the air you have to take in count another type of error. When kicking the ball on the ground you only have to worry about horizontal error, but when you add height on the ball vertical error comes in to play. The vertical component tells us that the height of the ball must be at least greater than 6.5 feet to avoid the goal keeper and the horizontal similar to the error on the ground. These two will combine to create a region very difficult if not impossible for a goalkeeper to cover during a penalty shot. Figure 4. Best shot on ground and in the air. sin(θ)=opp/hyp 11ft/√((〖36〗^2+〖11〗^2)) = sin θ → sin θ = 16.99° 16.99° is the best angle on the ground si n(θ)=7/√((〖37.64〗^2+7^2)) → sin θ = …show more content…
The effect of air resistance on the ball would only be minor, but would need a lot of calculations which is why it was left out. We are also going to assume that there is no “curl”, or “bend” on the ball. Using the technique of bending the ball changes the straight line path of the ball making it hard to calculate. Also, we assume that the preparation leading up to the kick is perfect, and that there will be no errors in the initial shooting velocity. There is no error in the initial shooting velocity. All of these diagrams are shown for a right footed player (majority of players are right footed), however the diagrams can just be flipped to find the same numbers for a left footed
On the field, there is a specific area on each half of the playing field, known as “the D” or “the circle,” where players are permitted to shoot. When in the D, the ball is allowed to be lifted and hit as long as it...
Imagining myself as a high school soccer coach, I would like to optimize my team’s kicking performance. Some players consistently kick the ball successfully with the correct use of power and accuracy. To ensure that all players are able to achieve the same optimal kicking habits, this paper will document (1) the effective and ineffective habits of kicking, (2) describe biomechanical based kicking assessments, (3) describe how these assessments will measure the effective aspects of kicking and expected findings, and (4) provide suggestions on how I may modify programming based on the insights gained from these assessments.

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...
In today’s world, the benefits of sports are huge. Sports are a way of teaching key skills that parents can’t such as sportsmanship, social values and many more. One of the most popular sports all over the world is soccer; hence soccer is the first sport that many children play and later on love. Within the past couple years, controversies have arisen over whether or not children should be heading the soccer ball while playing. For example, a header in soccer is when the player redirects the ball with their forehead, by taking it out of the air, to pass, or to shoot. With all the concussion prevention and media that has been centered on the NFL recently, the spotlight has turned over to soccer.
First off, when kicking a football, you have to factor in several things. You need to know what the distance is from the spot of the ball to the field goal and what direction you’re kicking the ball. You also have to factor in the direction the wind and how fast the wind is blowing. If the wind is blowing towards the field goal post, it will most likely increase the distance it will travel. If the wind is blowing away from the field goal post, the distance you can make a field goal will decrease.
In soccer, there are no time outs and little stoppage of play, so communication with coaches is limited. For a team to play well, each player must know what they need to do on and off the field. The objective of a soccer team is very simple; score and do not let your opponents score. When your team has the ball, every player already knows to help the person who has the possession of the ball to score. As soon as the ball is lost to the opponent,
The physics and science that go into throwing a football are very complicated. You must take into account all of the factors around you, as well as figure out the best angle to send the ball where it needs to be. Throwing a deep ball is all about using the right angle with the right amount of force. I want to find out at which angle is the best to throw the ball the farthest. The angles I will test will be a low angle at 15˚, a medium angle at 45˚, and a high angle at 75˚. The force throwing the ball will be the same and the tight spiral will be assumed constant, so the only factor changing will be the angle at which the ball is being thrown. I suspect the medium angle (45˚) will send the ball the farthest.
The average results were calculated and were recorded on the table. Step 6 The average results were plotted on a line graph and was used to determine whether if the bounce height increased by the influence of the height dropped. Diagram of Method Image added later Results The results showed that the bounce of the ball was affected by height drop when the height increased.
First of all, you must take control of the ball and decide what to do with it. You only have two options. You either carry the ball on your own trying to score for your team or you pass the ball and move to get back the ball. Second of all, you need to use the inside of your foot to be more accurate. With you knowing what part of your foot use, choose the person you are passing the ball to. To choose who are you passing the ball to, make sure your teammate is open, that there are none of the opposite players near your teammate, and that your team will make a smart play to score. If an opposing player is near, there is an immense probability for the other team to intercept the ball. Along with that, the other team might score against
In conclusion, football and soccer have their similarities, but these similarities are superficial. There are many fundamental differences, such as the use of one’s hands being illegal in soccer, except for the goalie when he/she is inside his/her respective eighteen-yard boundary. Another example is the alternation of a team’s offense and defense in football as opposed to the simultaneous effort of the offense and defense in soccer. These differences in rules, rituals, and concepts distinguish these two sports from each other. However, there are similarities, such as the fact that both sports allow eleven players on each team to play on the field at a time. Also, the area where one scores is in the same locations in both sports, the end zones of football and the goals of soccer are on opposite sides of the field.
The amazing game of soccer is played on every continent, and is the world’s most popular sport. It is proven to be one of the number one sports to be played and watched. Because its fans and players are so dedicated, the sport continues to grow. Requiring only a ball and open space, the activity is available to anyone, whether rich or poor, male or female, athletic or not. Over the years, soccer has won the hearts of many because of its unique history, many benefits, and notable achievements.
with, kicking, or passing it. With passing, though, you can only pass the ball backwards or directly to your side, never forward. Like football, you score by running the ball into the endzone or by kicking it through the uprights. Also, you must touch the ball to the ground for it to count, and it is worth five points. When kicking, the ball can be kicked from anywhere spontaneously. If it passes through the uprights, it is worth three points, as in football.
Soccer is a sport that is all about motion and how to use movements most effectively. Speed and velocity are very important when it comes to motion because with out them there would be no motion. When playing soccer speed is essential to being a productive player. The game is fast paced and so the players must also be quick on their feet. Soccer players may not know that velocity is essential to being able to control their movements. But physics proves that both are essential to soccer. Speed and direction are b...
