What makes the ball curve: Soccer players can make the ball curve by applying a Force, kicking, to the ball that is not in the center of the ball itself. When the ball is struck on the side by a player the ball spins while it is moving forward. In the case of the picture below, the soccer ball was struck on the right side of the ball and is spinning counter-clockwise. What causes the ball to actually curve in the air is a difference in the pressures on either side of the soccer ball. On the left side of this soccer ball, the air is moving faster, than the right side, relative to the center of the ball. This causes a lower pressure to develop on the left side of the ball, while on the right side there is a higher pressure because the air flow is moving slower relative to the center of the ball. This difference in air pressure causes the ball to curve to the left during its flight path. This curve is known as the Magnus Effect after the physicist Gustav Magnus.
The shape of the soccer ball is…round! But in mathematical terms, the soccer ball is usually in the shape of an Archimedean Solid. This solid has 32 faces, 12 are pentagons and 20 are hexagons. On the Apollo 17 mission astronauts played soccer with a 200 pound moon rock. Just imagine playing any sport with something that heavy…ouch!
There are many different soccer balls in use today. Each company claims that theirs is the best one out there but in all reality soccer players only like to play with soccer balls that they are used to. In fact, the ball used for the World Cup in 2002 was supposed to be the best one ever made by Adidas but many of the players in the World Cup hated it because it was new and they weren’t used to it.
When asked the question: “If you dropped a soccer ball from a height of 3 meters and assumed that the ball bounced back up to half its previous height, how long would it take the ball to come to rest?” most people would answer never because it would be continuing to bounce forever, we just wouldn’t be able to tell. However, this statement is wrong.
The materials comprise of smooth materials which help to control the ball. The soccer cleats require sensitivity so the player is able to perform skills with the ball. These materials tend to have a glove like fit on the player’s foot which significantly improves ball control. The material needs to be smooth so when controlling the ball in mid air the trajectory of the ball does not change. In other circumstances such as when the ball is approaching fast and a player needs to trap it. The player needs to apply a force equal but opposite to the ball in order to stop its motion. The glove like fit of the boots aids the player to stop the ball. The smooth material also help the player to be able to pass and shoot the ball properly. If it weren't smooth the ball would go in a different direction which was not intended. Newer cleats have a concave feature which gives the ball curve when struck with the appropriate force at a point on the

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.
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...
Physics is everywhere. Consequently, physics is a part of sports and more specifically, hockey. As the scientific discoveries progressed with time, so did the advancements in the sport of hockey, reflecting on how important and influential science truly is. Physics takes part in the ice, the skates, the protective gear, the shots, goaltending, and all other aspects of ice hockey.
There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is also a high energy compound producer found in the cells. These three chemical reactions are conducted to continue muscular work. The first system used in a game of touch football is the ATP PC system. This system is stored into the muscles and used in short durations for up to 10 seconds and doesn’t not require oxygen therefore being anaerobic. ATP lasts approximately 3 seconds, and then Creatine phosphate (CP) will continue until all ATP PC energy is used up. The use of ATP is high intensity and would usually be used in a 50m sprint or a pass in touch. Once the CP energy is used up the body then switches to the lactic acid system. This is because of the breakdown of glucose, resulting in the production of lactic acid. The lactic acid system an anaerobic energy system, which lasts for approximately 30 seconds to 2 minutes, and is the conversion of glycogen to glucose. In relation to a game of touch football, the lactic acid system could be used during a quick wruck, as the movements required are a...
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.
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.
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 in 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 devoted, 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.
The sport of soccer has overcome many changes through the years. In particular, women’s soccer compared to men’s soccer has gained much notoriety. The widespread knowledge of soccer has spread throughout numerous countries. Soccer began as primarily a men’s sport, but today soccer is considered a sport that both genders participate in. Women’s soccer has changed dramatically over the years with the increase in popularity as well as new style and rules of the game.
As mentioned, soccer is the most popular sport on earth and has a rich history. There is evidence that a couple thousand years ago, people were playing a game similar to soccer. The modern game, played today in America, was not developed until 1863 when the original rules of no tripping and no hand balls were developed. The game started in the public school grounds of England but the basics of kicking a ball around were found in a Chinese military instruction piece estimated second or third BC. The form of football was called, “Tsu Chu”. Tsu Chu had the original concept of kicking a ball through a target, but while the soldier was being attacked by his fellow soldiers. During the Han Dynasty, the ball was made of leather and filled with feathers and the use of hands was not permitted “FIFA”.
...volved. Soccer requires the use of physics principles such as motion, distance, momentum, angular momentum, friction, and all three of Newton’s Laws of motion. It is important to understand how physics works and affects us even when playing soccer. If players know how physics, the small details, affect them they will be able to control the ball and be efficient in calculating the speed and impact of an approaching opponent. Soccer is a challenging sport, but knowing how the physics around the game works makes improvement almost a guarantee.
The European Football, or soccer, as Americans call it, is simply known as football. It is a sport played between two teams of eleven players with a sphere-shaped ball. It is played by 250 million players in over 200 countries, making it the world’s most popular sport. The game is played on a rectangular field with a goal at each end. The purpose of the game is to score by using any part of the body besides the arms and hands to get the ball into the opposite goal.
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.
