Introduction:
I chose this project because soccer is one of the things I love to do. Soccer is one of the most popular sports across the whole world. In soccer being able to curve a soccer ball is very helpful for multiple reasons. One reason is to bend a ball around the a wall of players. Second to possibly score an amazing goal. And last of all to make a simple pass around a defender to a teammate.
Anybody that plays soccer and enjoys it probably knows about the famous Roberto Carlos free kick. He scored this goal in 1997 against France in preparation for the 1998 world cup. The shot was taken about 30 meters from the net and a tiny bit to the right. He hit the ball so hard that it cleared the wall by a meter. It then suddenly curved to the left and went into the right upper 90.
When watching soccer most people don't think about the physics behind the flight of a struck soccer ball. That is why I am doing this project to see if the different ways the ball spins effects the trajectory of the ball. I will be focusing on three different spins of the ball using my dominant foot for all strikes on a ball at rest. All balls will be struck with similar force and in the same direction with similar lift. I will be measuring the distance traveled by each strike and its deviation from the original flight path. This will help to determine if the advantages of spinning the ball outweigh any negatives.

In order to begin looking at the physics behind the trajectory of a kicked soccer ball we will start with seeing how Newton's Laws of Motion come into play. Newton's 1st law states that “any object at rest, will tend to stay at rest, and any object in motion, will tend to stay in motion unless acted on by an ...

In lacrosse, the overhead shot is the most vital part of the game and the most important skill that an offensive player can have. The goal of the lacrosse shot is to create a scoring attempt with peak speed and accuracy. Each player is different regarding personal technique; however, the basis of each shot remains the same and are interpreted through six phases. The general purpose of this paper is to describe trunk rotation and its impact on power and accuracy which will maximize the potential of a lacrosse shot.
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.
Soccer are footwear which are worn for playing soccer. They play an integral part in a player’s performance. Modern day soccer cleats are far from the basic soccer cleats of the past. They involve different types of science and technology.
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...
The movement pattern of a soccer kick is a proximal to distal motion of the lower leg. Hip activation occurs to begin movement of the thigh through multiple planes. There is a backswing and a forward acceleration by the thigh, shank, and knee extensor. Where the ball ends up (accuracy), and how fast it moves (speed), depends mostly on foot to ball contact (Kellis & Katis, 2007).
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.
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.
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.
In the 19th century, soccer started to come to life in America. Some colleges started to play the game in the 1820s, with the first contest taking place at Harvard in 1827. Then, a huge invention took place in 1855. That year, the Charles Goodyear soccer ball was invented. Charles Goodyear created these soccer balls with vulcanized rubber. 12 years later in 1867, soccer took two huge steps. The first standardized soccer rules were published that year. Now, graduates from different schools could play together and had proper rules to follow when playing a game. But later that year, another just as, if not mor...
This investigation aims to determine the ideal air pressure inside and the ideal material of a ball in order for that ball to achieve its greatest bounce height. This report will be focusing on how the air pressure and material of a soccer ball, basketball and volleyball affects the bounce height of each ball.
Soccer the way we play it came from England in the 1800’s. Soccer was not that popular until the mid-1900’s. Today soccer is very popular and it is one of the nations fastest-growing sports. There are many exercises and drills you can do to improve how you play soccer. There is also many physical conditioning that players can do. Soccer can help you stay fit and healthy. Many people can play soccer and benefit from it. Soccer is very fun and a great recreational sport.
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.
Much attention has been given lately to the effect of heading the soccer ball in youth soccer. Some people say it causes major brain damage later in life. Other people say that there are no major injuries from the ball, it is the collisions between players that causes injuries. I belive heading the ball causes injuries and it should be banned from youth soccer. Heading is seen as dangerous and kids are still growing and developing and shouldn't have to have head trauma at such a young age. Another reason to disallow heading in youth soccer is that the skill is improperly taught, or not taught at all, to many kids who participate in this sport.
There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
The laws of the football game were initially classified in England by The Football Association in 1863. ’’ 2. What is the difference between a GAMEPLAY Association football is played in agreement with a set of rules known as the ‘Laws of the Game’. The game is played using a sphere-shaped ball of 71 cm circumference, known as the ‘football’ or ‘soccer ball’.
