Physics of Ice Skating

The “Miracle on Ice,” where the United States defeated the Soviet Union in the 1980 Winter Olympics at Lake Placid, New York will forever be known as one of the greatest moments in American sports history. This game was about more than just sports though, it signified American strength, even when faced the greatest adversities. The United States was suffering through Vietnam, Watergate, and the wrenching upheavals of the 1960s. Many believe this game was even the beginning of the end for the Cold War. The Soviet Union had won the gold medal in six of the seven previous Winter Olympic Games, and were the favorites to win once more in Lake Placid. The team consisted primarily of professional players with significant experience

The fastest growing sport in America is lacrosse, and in order to play lacrosse, it is important to first understand the physics of the game. Lacrosse players around the world use physics while playing without even thinking about it. With no knowledge of physics, it would be pretty difficult to master the fastest game on two feet. One of the worlds greatest scientist, Isaac Newton, established three laws dealing with physics, and using these laws will make it possible for a lacrosse player to understand what he or she needs to do in order to throw a ball. Newtons first law deals with inertia, his second law deals with the relationship between mass, acceleration and force, and his third law deals with opposite reactions. When talking about lacrosse, it is essential to cover Newton’s first law, his second law, and his third law in order to understand the physics behind throwing a lacrosse ball. .

The movement of the puck depends on a lot of physics, such as friction. “Friction is a force that opposes motion in a particular direction. Friction occurs when the surfaces of two materials come into contact with each other. Since no surface is completely smooth, there will always be a frictional force that opposes motion. The magnitude of this force is

As everyone knows, ice hockey is played on ice, which makes it an extremely high paced game. Unlike ice hockey, Roller hockey is played on a plastic floor that consists of many six-inch by six-inch tiles. The plastic floor makes roller hockey a much slower paced game than ice hockey. The reason that roller hockey is so much slower than ice hockey is because there is more friction. The friction is produced in the

Many researchers are interested in the generation of angular momentum during turning dance movements. In a study on the pirouette en dehors, researchers found that skilled dancers generate larger vertical angular momentum as the number of turns increases by predominantly increasing the rate of momentum generation. Angular momentum is generated when the dancer applies a torque about the vertical axis by pushing sideways in opposite directions with both feet. The normal fourth position preparation is ideal for creating this angular momentum as the feet exert equal horizontal forces in opposite directions to produce the twisting effect, or torque (Kim et al., 2014). Thus, the vertical angular momentum is generated from the torque applied by the feet through the foot. In their book,

After a competitive skater gets off the ice her or his skates are almost filled with snow from jumping and spinning. The skater usually skates as long as possible so after they get off, they don’t have much time to dry off their skates and when she or he doesn't dry his or her skates, the skates will rust. When skates rust they will breakdown faster and will overtime be unsafe to skate on. Therefore parents will have to buy more skates which range between six hundred dollars for the boot and five hundred dollars for the blade. However, now there is a product called Stick, Soak, Stay.

Skating can be very confusing and you may not know what to start out with or where to get parts from Also skating can be a fun form of exercise and a way to connect with new and old friends.

Turning is a major part of a dancers training. Most dancers can spin at least 10 times together. Sometimes some dancers can only turn 3 times. It depends on the strength of the dancers legs and feet. Angular velocity is a way to figure out how fast an object can spin. The rotational axis can vary due to the type of dancer they are. Rotational interia is also an important role in a dancers turns this indicates the interia of the rotations. Interia in general is the tendency of an object to keep doing what it's doing. If a dancer has a large angular momentum it will be a harder for the dancer to slow down and stop spinning.The Torque is a measure of how much a force acts on the dancer for the dancer to rotate.

Dance is related to many things such as dogs,songs, ocean etc.. What is dancing? Dancing is a hobby, or an activity that pleases someone. People even do it for entertainment, money. There is so many types of dances like ballet,jazz, kpop, classical, and tap dances. Dancing can even be part of your religion.i am from Nepal and my culture is hindu. So i do classical dances. Dance springs from a human desire for personal expression and social connection. Dance is art that people use to express their feelings and show who they are. Dance can be used in many ways. Almost anyone can dance regarding to their age and ability. The movement of the body shows ideas or feelings that cannot be converted into words.

Therefore, to initiate a backward giant circle the gymnast must first exert a force to set the body in motion, and this is usually done by a

One sunny day, I was speeding around my court with my rollerblades. I went inside to ask my parents if I could go to my friend’s house, and they both replied, “Yes.” Halfway to his house, I tripped, and fell into the thin layer of grass. And this is when I recalled when I first started rollerblading.

Have you ever gone outside and you had nothing to do? Well there are two sports you could attempt. The first one is mountain biking ,and this sport is very fun and exciting.

Ice skating, one of which difficult for a lot of people to master just in the matter of a year or so. Most people usually spend their whole lives trying to perfect different techniques to their art. Competitive ice skating usually an elegant dance that is performed in a specific amount of time to be judged on. Sounds easy right? Well easier said than done.

Players in an offensive mode, with the ball, can use tactics and forms of physics which can bring the defence off there feet, to enable an easy path to the basket. This scenario is called breaking the defenders ankles. Breaking the defenders ankles is a term which relates to the defender being subjected to a large sum of momentum causing an instability in their ankles, consequently giving way. A players momentum can be calc8lated through the use of their mass and final velocity as followed; p=mv, p being the magnitude of the players momentum, m being the players mass, and v being the velocity at which the object or player is travelling. Due to the velocity and momentum being vector, the direction of each determine the final outcome. As the offensive player travels in a particular direction at a velocity, the defender would naturally defend by moving and following in front, guarding the offensive player. As the offensive player has a mass and a directional velocity, the offensive player can switch direction abruptly, causing the defenders momentum to continue in there initial same direction. The basic forms of physcis, such as momentum, can significantly determine an succesful or unsuccefeul defencive or offencive play. Therefore minimizining the risk of the metioned senarios, ankle bracing can be worn to increase the stubility of the defender in

The Glorious Revolution that occurred in 1688 to 1689 was a bloodless revolution in England that was a turning point in modern history. The true glory of the revolution was that it contained no massacre and that a settlement by consent was reached on the religious and political differences that had divided parties for ages. A thinker during the time, John Locke came up with new models and inspirations for the evolving concept of government. Locke argued that power came from the people, not from a divine right to royal rule. Kings should therefore be restrained by institutions that protected the public interest, including certain general rights to freedom and property. Therefore. a more democratic form of government known as a limited monarchy replaced absolutism and at the same time limited its power by the 1689 Bill of Rights. The revolution established the supremacy of parliament over the crown that set Britain on the path towards constitutional monarchy and parliamentary democracy (Maurice, 2017). The king and queen became figureheads, when before they were absolute monarchs. In 1660, when Charles II was on the throne, Englishmen were uncertain about the Stuarts and suspected him of Papal tendencies and absolutists learnings. Charles II did not adhere to Parliament since he had favoring alliances with Catholic powers in Europe. When Charles II died in 1685, Charles was succeeded by his brother James II, Duke of York. The Whigs, a parliamentary group did not want a
