Physics in Cricket Essay Example

Physics in Cricket Paper Cricket is not a game that most Americans know about, however, it is a popular sport in Australia and in other British parts of the world. This sport is not unlike any other sport in the area that it involves a great deal of physics. However, this paper will focus on the aspect of bowling the ball and the batters reaction to this. When comparing Cricket to other sports that most Americans know, the closest match that can be found is baseball. For example, a ball is thrown toward someone with a bat, and the person with the bat attempts to hit the ball outside of a set boundary. Also, the scoring system is cricket is based upon runs. Sounds very similar to baseball, right? Well, it is much like baseball, but the terminology used is different. For example, in baseball, the person who throws the ball is called a pitcher, but in cricket, this person is called a bowler. In contrast, the person who hits the ball with a bat is called a batter, however, a bat in cricket is much different than a bat in baseball. In baseball the bat is round, but in cricket the bat is shaped like a long paddle, meaning it is flat on two sides.

A controversy that arises in both cricket and baseball alike is the question of â€Å"what size bat should be used? † The answer to this question is, whatever size allows you to put the most possible velocity while making the ball soar off at around a 45-degree angle. This depends on what bat a person is comfortable with. For example, a person might be able to swing a light bat at 45m/s but a heavier bat at 38m/s, therefore in theory the lighter bat would take a ball further because it has more velocity to transfer to the ball, right? Not quite, a heavier bat packs much more momentum and energy, so the force from that would make the ball go further, so the trick is actually swinging the heaviest bat that feels comfortable to swing, because when trying to hit the ball out of the field, this power comes in very handy. The bowler’s role is much different from the batter’s. The bowler’s objective is to get the ball past the batter and hit the wicket, the target that the batter is protecting. One way to approach this feat is to throw the ball as fast as possible without any spin past the batter in hopes that hey will miss and the ball will luckily hit the wicket, but this theory does not work all of the time. For this reason we have another approach, using spin. Since the bowler must bounce the ball, the bowler can make the ball switch directions, increase or even decrease in speed very quickly. While the first technique uses only two dimensions, this technique uses three dimensions. By adding spin to the left, the ball in result will kick to the left when bounced, and the same is true if spin were added to the right, it would kick right very sharply. To cause a ball to kick forward, topspin must be added to the ball, meaning, the ball will be spun in a forward direction. This causes the ball to dive toward the ground, then when it bounces, dive forward at a more reduced angle than what it entered, therefore the ball comes in closer to the ground. Backspin is added by, as you begin your bowl, spinning the ball backward as it is thrown. This causes a slight â€Å"glide† through the air, because of air resistance, and upon impact with the ground, the ball will bounce up at a lesser angle than without spin. Therefore, in contrast to topspin, if it hit the ground in the same place, a ball with backspin would get to the batter at a higher height than would a ball with no spin implied. Next, we have the angle at which the ball hits the ground. With no spin implied, the ball will project itself, or bounce, away from the ground at the same angle it entered. Even though the height at which the ball approaches the batter relies on speed, it also relies heavily on the angle of the bounce. In cricket, all bowlers have, depending upon height of the bowler, around the same place that the ball leaves their hand. Because of this, the angle at which the ball strikes the ground depends on how close or how far away the bowler aims for the ball to hit. If the bowler has measured out how far the place where he plans to bounce the ball, we can calculate the angle at which the ball will strike the ground, and then calculate at what height the ball approaches the batter. However, adding topspin or backspin to a ball defies this. As said earlier, topspin causes the ball to bounce at a lesser angle than normal, depending upon the rate of spin. And adding backspin causes the ball to bounce at a higher angle, also depending upon the rate of spin. In conclusion, physics is used in all sports, and why would cricket be any different? Even though cricket is a complicated sport with many weird rules and regulations, it still uses the same momentum, forces, gravity, and velocities, among many other physics concepts that the sports we know and love use. Particularly, physics is seen through the aspect of bowling the ball and the batter’s reaction to this.

My concept of Modernism in Literature

My concept of Modernism in Literature ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ ÂÆ'‚‚ The movement known as "Modernism" began in the first decade of the 20th century and was a reaction against all aspects of Victorianism. Literary interest shifted from the external to the internal, to the psychology and motivation of characters and their roots in deeply shared experience, influenced by the theories of Sigmund Freud and Carl Gustaw Jung. Joseph Conrad, D. H. Lawrence, E. M. Forster among others, explored mind and feeling in fiction still largely conventional in narrative and dialogue. Virginia Woolf and James Joyce, however, experimented with the "stream of consciousness" to express a character's thoughts more directly. Poetry broke even more with the past, replacing traditional prosody with "free verse" and favoring the shorter poem with sharp, concrete imagery. This period was marked by a more colloquial and relaxed use of language. New styles allow ed the reader a more open and less directed approach to the text. Scenes and topics once banned from literature were now.Admitted, with taboo words appearing in print and a more explicit presentation of sexuality and human differences.What is more, the 20th century is above all, in art and in literature, the century of the individual. Main concern of the comparatively new science of psychology is personality. The psychology of personality development describes an evolution within the lifetime of a person. A whole series of tensions are created between the "known" and the new, the static and the dynamic. The tension between the idea of freedom and the idea of responsibility. Culture and personality interact, and help shape and explain each other. In Modernism, there is reflected the modern view of man, an understanding of his motives, of the forces, which shape him, and of the values, images and meanings, which are both his interpretations of experience and the shapers of his...

Idustrialize America - Essay Example Unfortunately his efforts did not prevail, the power was once again given to the Army and there was even a period that followed in which the Democrats regained the impetus, re-enacting laws that revived the era of slavery for these newly freed men and women. Lynching and race riots were rampant in some States, and the Redeemer Government and Klu Klux Klan were determined to re-establish white supremacy. It seemed that all the efforts of the Reconstruction had been for nothing. Notwithstanding that they had just been through a harsh and debilitating war, President’s Abraham Lincoln wanted to be magnanimous towards the South. In December 1863, he placed the idea that a State could be integrated into the Union if 10 percent of the population count under 1860’s census supported emancipation. Tennessee, Louisiana and Arkansas were won over by the Union through Lincoln’s Ten Percent Plan. However this compromise did not sit well with the diehard Republicans, nor some in Lincoln’s own party who feared that it would once again undermine the cause of emancipation by bringing economic slavery to blacks on white owned cotton ginning farms. The mood of the South was rebellious and unrepentant. They sought to regain control of the situation, and could not bear to see blacks getting education, voting rights and freedom. On his part, President Andrew Jackson who took up the reins of Government following Lincoln’s death tried his best to follow the former’s lenient policies for the collective benefit of all. He appointed new Governors in 1865. Unfortunately his efforts did not meet with success and were spurned by the diehard Republicans. They challenged and undermined his efforts, rejected his nominations from the South and eventually managed to oust his Government in 1865-66 after success in the 1866 Congressional elections. They managed to regain control of Congress in
