There is physics all around people in their everyday lives. People do not think about the many ways physics influences them. Physics can be found anywhere including in sports, and soccer has a lot of physics that are very crucial to the sport. The laws of physics, including physics on a soccer player, ball, and Newtons three laws, are essential to playing soccer. The laws of physics have a large impact on the soccer ball. This is demonstrated in the momentum on a ball. Whenever a soccer player kicks the ball, they transfer the momentum from their leg to the ball; this is the result from the formula for momentum p=m*v. The momentum is calculated by the mass of the soccer player multiplied by his velocity. Also displayed here is the law of conservation of momentum in that when the leg kicks the ball, the total momentum is conserved between the leg and the ball, and also when the leg slows down the velocity of the ball, the momentum is also still conserved (Acevedo, par. 1). Don’t waste time! Our writers will create an original "The Physics In Soccer" essay for you Create order In addition to momentum, friction is always involved in soccer whether it is rolling friction or sliding friction. Rolling friction is the friction that acts upon an object when it rolls across a surface. Rolling friction can be demonstrated through the ball rolling across the grass or turf field. There are different types of fields that affect the balls friction on the field. With grass the rolling friction is more and slows down the ball faster. On turf the friction takes less affect and the ball can move much faster because it rolls more naturally and faster across the field causing less friction. Sliding friction occurs when two solid objects slide over each other. Sliding friction takes effect when the players are running up and down the field from all over. Sliding friction makes it to where the players are not sliding all over the field but makes it where they are able to get grip and turn quickly toward the ball. Running is an example of sliding friction and running is a huge part of soccer so that is where it takes place as well. The acceleration on a soccer ball greatly influences the game. How much acceleration is determined on how hard the ball is kicked by the soccer player. The ball must be kicked with just the right amount of acceleration for it to roll the distance you want it to go. There is more acceleration put on a soccer ball when it is shot so the ball can go much quicker and lift up faster. On passes there is most of the time less acceleration because the player wants it to get to the teammate as accurately as possible. The acceleration on the ball is a big factor and is very important to the game and a big factor to consider while playing. Acceleration is another huge part of soccer, whether the player needs to speed up or slow down or keep a pace, acceleration is there taking effect. Acceleration helps the players beat their opponents quickly with a quick burst. Acceleration helps on defense as well, when running back the player must accelerate to get in front of the offensive player. The amount of acceleration depends on how far the ball is from the player and how far the opponent is from the player. The player must determine how much acceleration they must use to get to the opponent at the precise time. Acceleration again is a huge part in soccer because it affects the running and timing of the play and changes the whole game. The Magnus effect is a big part of soccer, it mainly takes place in the ball but is influenced by the player kicking the ball. When a soccer player kicks a soccer ball they can kick it from a variety of ways. From the side, underneath, on top or in the center. Depending on where they hit the ball is how much it will curve side to side or spin backwards or forwards. This curve or spin is the Magnus effect taking place on the ball because where the players kick is placed affects the balls spin and curve and that is the Magnus effect. The Magnus effect can only take place because of gravity, which is mainly what affects the ball. The gravity on a soccer ball is strongly affected by many different factors. The weight of the ball, the drag caused by wind or a object in the way, the lift and spin other wise known as the Magnus effect, the direction and the rotation. Gravity determines where the ball falls and which direction it goes but the player can affect it too as well as gravity. Momentum on a soccer player is affected by many things. Including the players speed and mass. The players momentum shifts throughout the different times of the game. It can be greater in more situations than others also less in other situations. Say a player is on a fast break away and they increase there acceleration. There momentum shifts to a higher state as for the defense the player are not as active. The momentum is also affected by the players mass. When collisions happen two player paths cross and depending on the players mass and speed the greater mass and speed will prevail. The speed and mass take effect because the larger and faster is the greater momentum so that player would win that battle between the ball and the other opponent he his facing. This collision and momentum is strongly influenced by the acceleration of the player. Acceleration is another huge part of soccer, whether the player needs to speed up or slow down or keep a pace, acceleration is there taking effect. Acceleration helps the players beat their opponents quickly with a quick burst. Acceleration helps on defense as well, when running back the player must accelerate to get in front of the offensive player. The amount of acceleration depends on how far the ball is from the player and how far the opponent is from the player. The player must determine how much acceleration they must use to get to the opponent at the precise time. Acceleration again is a huge part in soccer because it affects the running and timing of the play and changes the whole game. Furthermore, Newtons three laws play a huge role in soccer. Newtons first law of inertia states that an object at rest will remain at rest, and an object at motion will remain at motion until acted upon by an unbalanced force. This law is seen in soccer in that when a ball is kicked or thrown, it will remain in motion until an unbalanced force such as a player, friction from the soccer field, or the goal post interferes with the soccer ball; on the other hand, when a soccer ball is placed stationary on the ground, it will remain at rest until an unbalanced force acts on it (Acevedo, para. 1, 2). Next, Newtons second law of motion relates force, mass, and acceleration in the formula Fma. According to this equation, the more force that a soccer ball is kicked with then the larger acceleration the ball will have since the mass will always stay the same (Acevedo, para. 3, 4). Lastly, Newtons third law of motion states that for every action force there is an opposite but equal reaction force. This is seen in that whenever a soccer player kicks a soccer ball, he will feel a reaction force from the soccer ball onto his foot, but it is not as strong because according to Newtons second law of motion F=ma since the soccer players foot has more mass he will feel less acceleration (Acevedo, para. 5, 6). As shown, Newtons three laws of motion impact soccer significantly. Soccer would not be able to be played unless physics had so strongly played its role in the sport. Soccer relies heavily on physics, and when considered carefully, other things such as playing other sports or a countrys economy also depend on physics. People do not realize of how strongly related physics is to not only soccer and entertainment but to every part of their lives. Understanding physics will not only help us play soccer but will also help us to follow Genesis 1:28 in which God commands people to be fruitful and have dominion over the earth (New King James Version, Genesis 1:28). God created the rules of physics for humans to learn and to use to benefit His creation. Works Cited Acevedo, Juan. Momentum and Impulse.

Looking Back Upon Civil Rights, WomenS Campaign For Suffrage

Looking back upon civil rights, women s campaign for suffrage and equal standing in society shines as one of the most important movements in US history. The literature of this time reflects the ideals from the movement. The 1890s marked the beginning of the Progressive Era; a period dictated by the emergence of women from all levels of society entering the public sphere and becoming self advocates. In 1892, Charlotte Perkins Gilman authored The Yellow Wallpaper, a piece that symbolically represented the era. By the 1940s women had gained the right to vote and had begun to work, much to the chagrin of men. In 1947 Tennessee Williams produced his classic play A Streetcar Named Desire. While similar in their quest to bring women’s struggles†¦show more content†¦Blanche’s writing shows her dependency on men and conflicts with the sentiment of the self-supporting woman that arose in the 1940s. While she attempts to depict herself as an independent woman, it is thin ly veiled and shows that her self-image is completely dependent on how men view her. Women during these time periods, despite their desire for equality, were still expected to stay in their â€Å"lane.† Blanche, upon arriving, veers sharply away from that lane, and it is Stanley who fights to put her back in her place. During â€Å"Poker Night† Blanche is a nuisance to Stanley. She plays the radio, takes a shower, and even steals Mitch from the game. In this instance Blanche breaks away from her prescribed gender role of subservience and disrupts â€Å"the man’s world.† However, this is instance of independence is nullified moments later. As she conversates with Mitch she once again shows her dependence on men. â€Å"Blanche waltzes to the music with romantic gestures. Mitch is delighted and moves in awkward imitation like a dancing bear† (2321). Blanche oversexualizes herself in an effort to gain his approval and boost her self-esteem. Unlike Blan che, who is constantly masquerading as independent woman, the narrator in The Yellow Wallpaper follows a natural progression away from her assigned gender role. Early on she is trapped in a room much like a prison, â€Å"for the windows are barred for little children†¦Ã¢â‚¬  (1671).
