Physics of the Ball
How and where you kick the ball is the most important aspect within the game of soccer. Lets say you kick the ball perfectly giving it no rotation (or spin), this means that you have given the ball a velocity (v) and an initial angular speed of zero. When the ball comes into contact with the ground it will begin to spin because the ground is not frictionless. The soccer ball will eventually begin to roll without slipping, which is when the balls center of mass is equal to its angular speed. Now assume that you want to strike the ball so that it immediately begins to roll without slipping. The diagram above shows us how we can accomplish this and the equaltion of s=R(theta) will give us the distance from the center of the ball that you need to kick. The answer to this problem turns out to be s=0.4R, so you would strike the ball a little less than half of the radius above the center line.
Friction is a huge factor when considering the game of soccer. When a soccer ball is moving along the field there is constantly a frictional force working in the opposite direction of the balls movement. There is an equation that can be used to find the friction force working against the ball and it is f=mN. This is where f is the frictional force, m is the coefficient of friction, and N is the normal force pointing upward. The coefficient of friction is dependant upon the surface type and ball being used, it is not a constant. This tells us that the coefficient of friction will cause the ball to roll slower when it is large and not as slow when it is small. This also shows that the more friction there is between the ball and the field the slower the ball will roll.
How physics students cheat!
When dealing with projectile motion physics students are normally allowed the assumption of two things;
1) The free-fall acceleration g is constant over the range of motion and is always directed downward.
2) The effect of air resistance is negligible, meaning there is no air resistance on the projectile.
With these assumptions we find that the projectile's path is always a parabola.
How this cheating pans out!
Baseball is a fascinating sport that is exceptionally fun to play. This assignment is all about understanding the physics of a few key aspects of this sport. One might ask what physics could have to do with baseball? Like most sports baseball involves physical motion. Baseball encompasses all three planes of motion through throwing, hitting, and fielding. All of the classical laws of mechanics can be applied to understand the physics of this game.

These are the four primary factors. The initial velocity is the speed and direction of the object right as it begins its trajectory. The initial height may vary also. In the case of a baseb...
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.
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.
Soccer is the worlds most popular sport. It is the national sport of most European and Latin-American countries, and of many other nations. Millions of people in more than 140 countries play soccer. The World Cup is held every four years. Soccer is one of the most famous international sports. Soccer is known world wide and is played in the Olympics.
According to Davidhanzy (1998) if a soccer ball is dropped on a hard surface it will bounce back lower than it started. This kind of motion is called the bouncing of the soccer ball. Th...
This paper will explain a few of the key concepts behind the physics of skydiving. First we will explore why a skydiver accelerates after he leaps out of the plane before his jump, second we will try and explain the drag forces effecting the skydiver, and lastly we will attempt to explain how terminal velocity works.
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.
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 has proven to be a notable sport throughout the years starting with its unique history. Soccer began all over the world tracing back thousands of years. The Chinese, Japanese, Italian, Ancient Greek, Persian, Vikings, as well as other nationalities all played a form of the game soccer. In China and Rome, games that were similar to soccer were played around 200 B.C. (Helmer and Owens, 5). People believe that soccer started more than a thousand years ago when villagers killed attacking pirates by cutting off their heads and kicking them around (Helmer and Owens, 5). As time went on, people in Europe also played a game similar to soccer during Medieval Times. In fact, soccer was used to prepare warriors for battles in Ancient Greece and Rome (Dilov-Shultheis). In later history, the English called the game “Football” because soccer was played by kicking the ball with the foot (Helmer and Owens, 6). The name “soccer” came to be when the American’s Association Football was shortened to assoc., and later to soc. Eventually in 1895 it was called soccer (Helmer and Owens, 9). By the late 1700s and 1800s, soccer was played in many universities, but the rules were not ...
The motions of throwing, batting, and fielding will be presented in physics terms and ideas. Physics plays a big role in sports. One particular sport is softball, where we will be seeing different motions represented.
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.
