What Is Physics and What Are Its Uses?
Physics, a branch of science, is traditionally defined as the study of matter, energy, and the relation between them. The interaction between matter and energy is found everywhere. In order for matter to move, it requires some form of energy.
Sports show many good examples of the relationship between matter and energy. For instance, a pitcher requires energy to throw a baseball at the incredible speed and accuracy that is needed to keep the batter from using his energy to try and hit the ball. The batter exhibits the need for a certain trajectory because he/she needs to hit the ball hard enough and keep it high enough to sail over the outfield wall. On the other hand, the batter must be certain to keep the trajectory low enough so that the ball will reach the fence.
Trajectory is also seen in basketball, where players must shoot the ball with enough arch to get over the front of the rim, and go through the hoop. The energy required to do this comes from not only the arms, but the legs as well.
The medical field has seen enormous breakthroughs because of principles of physics. Doctors are now able to use lasers for surgery. Lasers are based on the physical principle of light, and are devices for the creation and amplification of a narrow, intense beam of coherent light. New laser microsurgery can actually alter the shape of the cornea in the eye so the patient's eyesight can return to normal, and he/she will no longer need those bothersome glasses. Ultrasound is used in the medical field for destroying various unwanted substances in the body such as kidney stones. Ultrasound uses sound waves to dissolve these foreign bodies. If not for physics, ultrasounds would never have been discovered and utilized. MRI scans, another new discovery, are able to show a complete three dimensional picture of the interior structure of the body, and are extremely valuable in hospitals. These scans are based on the principles of electromagnetism, and the phenomenon that nuclei of some atoms line up in the presence of an electromagnetic field.
Understanding the dark matter of the universe, which has remained a mystery for quite some time, is based primarily on theories of physics. We have yet to see a black hole, but physics has explained what one is, and why we cannot see it. Otherwise we would have never known that it is an extremely
...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.
The safety of the players is the biggest concern in all levels of baseball. The belief that metal bats result in more injuries than wood contributes to the reasons MLB does not allow their use. One contribution to this belief is the difference in exit speed of the ball off the different bats. It was found that aluminum bats produce an average of 92.5 miles per hour exit speed, compared to wooden bats averaging an 88.6 miles per hour exit speed ("Baseball: Wooden Bats Vs. Metal Bats"). This is a difference of 3.85 miles per hour, which is significant considering the time it takes for players to react to a hit ball ("Baseball: Wooden Bats Vs. Metal Bats"). A study shows that it takes 0.4 seconds for a ball hit 93 miles per hour to travel 54 feet, and because the pitcher's mound lies at 60 feet-6 inches away from home plate, the pitcher has less than 0.03 seconds to react to a line drive hit to them (McDermott). While compared to the time it takes to blink an eye, 0.095 seconds, pitchers do not stand a chance against a line drive (McDermott). The use of met...
... for a clue as to where the ball will be hit. 'I think you're right,
The game of baseball can be divided into three broad categories: hitting, pitching, and defense. No other facet of the game gets as much attention as hitting. For example, every year the MLB puts on a home run derby. No other part of the game draws as much attention. The traditional statistic that measure hitting ability is batting average (BA or AVG). To find a players batting averag...
A good batter will use almost all of these rotational and torque energies either before or durning contact with the ball. After contact your body is relaxed and its remaining motion is smooth, this extra motion is caused by the momentum of the bat pulling the arms up and through.Your follow through is also very important, even though the ball has already been hit it is ideal that you complete your swing so that you're not thrown off balance by that extra momentum when you start to run.
...the knuckle ball will go the direction of least resistance. This makes the pitch very unpredictable and hard to control.
Simply put, a squeeze is a play in which there are less than two outs with a runner on third base who takes off as soon as the pitcher releases the ball, and the batter attempts to bunt the ball to allow the runner to score. The batter must make every attempt possible to put the ball in play and make sure...
The type of data that will be collected throughout this paper will be from Major League baseball from over the past years. There are various types of data for each part of the game, such as hitting and pitching statistics. Applied to that data will be the mathematical formulas and calculations that will help get us the end statistics that are so important to the game and they will show overall how math is an influential part of the game.
The origins of the super-massive black holes which concludes how they were formed and what caused them to form is an unsolved problem which is yet a mystery of astrophysics. ( Millis 2014)
When one throws a baseball properly they are using there entire body to generate a large force to propel the baseball. A general throwing position starts with a person rotated 90 degrees from there target with there throwing arm 180 degrees from the target and parallel to the ground. The person then starts rotating their body back towards their target while there throwing arm starts bending until it is almost 90 degrees to their elbow, while the arm is bending at the elbow the throwing arm is rotating such that the arm rotates back almost 180 degrees from the target. Meanwhile the person is leaping forward with the leg that was initially pointed at the target while there other leg is planted into the ground. The person is bending at their waist and the other arm is rotating into their body. Around the point where the driving leg strikes the ground the throwing arm is rotating foreword at a tremendous angular speed and the person lets go of the ball. At the point where the ball is let go the persons body pulls the planted leg forward and the throwing arm finishes its motion towards the driving leg.

Upon further investigation, baseball is more than just “One, two, three strikes you’re out,”there is a whole world of physics interacting and exerting itself upon the game, unseen to the human eye. So next time one sees a batter hit a home run off a knuckle ball at Coors Field in Denver, one will have a great appreciation for the physics of the game that came into play within that play.
Baseball is known as America’s national pastime, and has been played for over 100 years. Baseball can be a lot of fun, but is also extremely challenging to play, especially trying to hit a 90 mile per hour fastball. I am a very devoted baseball player myself, and over the years I have learned numerous key things about the game. Baseball does not only require physical strength to hit and throw the ball, but it also requires a great mindset, such as, mental preparedness, concentration, and a positive attitude.
of course zero cm. From dropping the ball we can see how high the ball
Science is a method of understanding how things work. It is important because we need science in order for things to work and to develop new technology that is used in every day life. It is personally important to me because I really want to become a vet when I get older and I would need to do really well in science. Even though science isn’t exactly my best subject, I am willing to put in the hard work and determination so I may eventually get better and learn what I need to know.
