The Cricket Ball in the Sport of Cricket
Cricket is one of the most exciting sports in world. It is played is most countries in world. Cricket is not that popular in Unites States but it is the most popular sports in countries like India, England and Australia. Making cricket popular in America requires describing its equipments and the game itself. One of the most important equipment of this wonderful game is Cricket ball.
The cricket ball is a little small than a baseball ball. It is round shaped, smaller than a wrist of an average size man. A cricket ball is made from a core of cork, which is layered with tightly wound string. It is covered by a leather case with a slightly raised sewn seam. The covering is constructed of four pieces of leather shaped similar to the peel of a quartered orange. A cricket ball only has one seam. The equator of the ball is stitched with string to form the seam, with a total of six rows of stitches. The remaining two joins between the leather pieces are left unstitched. The ball is about nine inches in circumference and only weighs between 5.5 – 5.75 ounces.
The surface of the ground where cricket ball is pitched matters a lot for the performance. This ball bounces a lot on a dry/hard pitch because of its hardness. However it's the other way around if the pitch is wet/damp, this ball loses it bounce. Weather is also very important factor on how the ball behaves. In sunny weather the ball don't do much but if it’s windy the ball swings in air a lot. Therefore when the weather is bad this ball sometimes becomes impossible to play.
The most dangerous thing this ball does is “Swing”. Swing which is achieved by keeping one side of the ball polished smooth and shiny and keeping the other side rough, and delivering the ball with the polished side forward, and the seam angled in the direction of desired swing. There are two types of swing balling in cricket. The out swinging ball moves away from the right-handed batsman, while the in swinger moves in towards him. Normal swing is achieved by maintaining laminar boundary layer air-flow on the shiny side whilst creating turbulent flow on the seam side.
Or maybe alloy bats and composite bats The middle of the ball is called the “Cork”. The core of the ball is made of long fiber kapok, in 2004 high-visibility yellow optic covering. Alloy bat son the other hand, are thinner and have more responsive barrels. Alloy bats are also more durable because they are made of aluminum. Composite bats are made of a carbon fiber,graphite, and fiberglass, and some also have kevlar. Kevlar is a synthetic fiber of high tensile strength used especially as a reinforcing agent in the manufacture of tires and other rubber products and protective gear such as helmets and vests. There are many different parts of the bats which is a big part to make the player and who they are on the field. There is a knob which is the very base of the bat. Directly above that there is the grip for the players so they can grip the bat on the handle. Above the grip there is the barrel of the bat where the ball hits, it is also the thickest part of the baton top of that is the end cap on the end of the bat.
The Physics of the Curve Ball Dad said that one of these days I would figure it out, but to this day I am still clueless. I have always been able to throw a decent curve ball; you don’t just throw 6 one hit games in your high school career without one. I have always wondered why and how the ball curves through the air, and it wasn’t until now that I have really had the chance to research a topic that has puzzled me for so long. I would bet that even pitchers in the “Big show” don’t know how or why, but they obviously have the talent and ability. I don’t know when the first curveball was thrown or who threw it, but there is a lot of controversy out there about whether or not the curveball really exists.
Many people might think that swinging the bat straight through the ball would be enough to hit the ball a decent distance off the bat. There's many more mechanics involved in the swinging process. Muscle has only a small part to play in the swinging a bat for power. There are two types of mechanics involved while swinging a bat, Linear and Rotational. Rotational mechanics are the dominant source of power in the swing. Out of the rotational mechanics come the two forces that help generate the speed and power of the swing, torque and the other comes from the energy of rotation. Speed from the energy of rotation comes from the path that your hands follow as you swing the bat. The speed generated by the circular rotation from your hands is like a ball at the end of a string, as long as your hands are moving in a circle then the ball continues to accelerate in a circle. So the bat will also move in at an increasing speed as long as your hands are following a circular path as you swing. Any foward movement of the hands or body in a straight line won't add to the overall bat speed.
Transition: First, I want to talk about the equipment used in the game of bowling.
Wikipedia gives us following definition of a bowling ball: “A bowling ball is a piece of sporting equipment used to hit bowling pins in the sport of bowling. Ten-pin bowling balls are typically hard spheres with three holes drilled in them, one each for the ring and middle fingers, and one for the thumb.”
Baseball to my way of thinking, is the greatest single force working for Americanization. No other game appeals so much to the foreign born youngsters and nothing, not even the schools, teaches the American spirit so quickly, or inculcates the idea of sportsmanship or fair play as thoroughly.
“Batter up!” the umpire yelled from behind home plate on the diamond-shaped field for the inning to begin. Adrenaline rushed through the players’ veins as the crowd cheering echoed from the bleachers to the outfield. Softball and baseball are team sports which both require an umpire and a diamond shaped field. All players are important. Most aspects of the games are the same. Each team has only nine players on the field at nine different positions. Each inning ends when there are three outs. Baseball generally consists of nine innings, whereas softball usually is played in seven innings. People think that softball is not as tough as baseball because they think that softball is a soft sport. I have been playing softball for about ten years, but prior to that I played baseball. However, the game of softball is on a whole different level. Softball plays require much more speed, and there is a greater possibility of getting injured. The game of softball is more hazardous and fast-paced than baseball.
All the math work, along with physics principles, aided in proving that math has a significant role in the game of softball. Although people know that math is included in softball, the degree of its inclusion is still a mystery to both the audience and players. As seen in the mathematics work and graphs above, an average throw of a regulation fast pitch softball is parabolic in shape. This parabola has a curvature known as the trajectory, or the bath of the flying ball. This trajectory and parabola increases as the distance of the throw increases, therefore, the maximum height of the throw increases. This proves that an average softball throw has many mathematical aspects that shape the way the sport is played.
First off, the knuckle ball. It is called the hardest pitch to hit. A pitch that seemingly floats like a butterfly and then magically drops into the strike zone, dumbfounding the batter and almost always resulting in a strike out. But how is this pitch actually thrown? The name of the pitch essentially entails how the pitch is thrown, the pitcher curls his fingers into his hand, placing the knuckles of his fingers on the ball, and releasing the ball in this manner and fashion. But why does this work? It comes down to the position of the laces. By throwing the ball off the pitcher’s knuckles, the ball exhibits no spin throughout the entire duration of the pitch. This allows different lift forces within the air is passes to exert themselves upon the ball. By doing this, the ball is subject to different planar movements as a result of different lift forces manifesting themselves upon the baseball that is thrown. In a simplistic explanation, this is why a knuckle ball “knuckles” as it is thrown.
of course zero cm. From dropping the ball we can see how high the ball

In 1910, the cork core was introduced, but there was still no regulations on what the inside of the ball would be made of. Finally, in 1934, the American League- “which favored live balls and big hitters”, and the National League- “known to use thicker, looser balls that favored the pitcher” came up with a standard ball. Neither the ball of the MLB, or the process used in making it, have changed much since then. (Stamp)
...al properties, the five most important being the length, diameter, weight, weight distribution, and stiffness of the bat. Bats are about six times heavier than balls and about six times lighter than a batter’s two arms. This is no mere coincidence. Tennis racquets are also about six times heavier than tennis balls. The factor of 6 is about the best ratio to ensure that energy in the batter’s arms is well coupled to the bat, and that energy in the bat is well coupled to the ball.
How Long does it take the different ages of tennis balls to lose its bounce.
...the more energy is lost and the less the ball bounces back. The less denting that occurs, the more energy is kept and the higher the ball bounces back.
