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
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.
Since other forces such as wind resistance or drag acts upon the ball in such a fashion, the ball should make a tight spiral as it travels through the air. If the ball was thrown with the ends perpendicular to the ground, the increased surface area being exposed to the wind resistance causes the ball to quickly lose speed and it wouldn’t be able to travel as far. “In addition to throwing the ball point first, the passer’s grip and release cause the ball to spin on its lateral axis, and he benefits from the aerodynamics of the ball’s ellipsoid shape.” Machin, ...
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 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,
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...
Having a proper soccer kick is a key component to being a successful soccer player. Understanding the biomechanics behind the movement is important in order to guide the player to improving this skill. Kicking is a whole-body movement, more specifically multi-articular (involving many joints), that can be affected by multiple factors such as the individual (age, gender, fatigue, leg dominance), the environment, balance, and coordination.
or past a goal to score a point. The cardinal rule in all varieties of
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.
The American Youth Soccer Association has rung in their opinions about the safeness of heading in youth soccer. John Ouellete (n.d), who is AYSO’s national soccer instructor, advises coaches to not teach heading before the age of ten and to use softer balls when first practicing. Additionaly, as stated before, kids can take the ball out of the air with other surfaces besides the head, so Oullete’s assertion that “Heading represents a player's earliest opportunity to play an air ball”, is false. Ouellete also claimed, “It [heading] also causes more apprehension than any other soccer skill, particularly with younger players.” If children are apprehensive with hitting a ball that’s traveling very fast out of the air, there is a higher chance they will use the wrong technique anyways.
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.
Soccer the most popular sport in the world, since is the sport with more active players with around 270 million athletes. By having registered so many players, it’s not surprising that this sport has more fans than any other sport worldwide. Every team looks for a player that moves the ball, and that creates plays to score. This means a person that pass the ball through the entire game. To pass the ball in a proper way is one of the main skills a player needs to play soccer. Passing the ball, keeps the game going. Without being able to pass the ball accurately to your teammates, more than likely your team won’t be able to score a goal. The key for passing is to keep things simple. This means passing the ball to your nearest teammate that is not marked by an opponent.
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...

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.
