Gymnasts use physics everyday. As a gymnast I never realized how much physics went into every motion, every back handspring, every mistake on the bars. If gymnasts were physicists (or at least knew more about physics) they would be better equipped to handle the difficult aspects of gymnastics. As a gymnast I learned the motions that were necessary to complete the tricks that I was working on, and as a coach I taught others the same. I never truly understood why a particular angle gave me a better back handspring or why the angle that I hit a springboard at really mattered when completing a vault. We are going to explore some of the different apparatuses in gymnastics and a few of the physics laws that are involved in them. We will not even barely scratch the surface of the different ways that physics can explain gymnastics.
Newton's Laws
Newton's Laws can be found in the textbook, Physics for Scientists and Engineers by Serway.
Newton's First Law
An object remains at rest, or in motion, unless an external force acts upon it.
Newton's Second Law
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely
proportional to its mass.
F = ma
Newton's Third Law
For every action force, there is an equal and opposite reaction force.
The Floor
There are many aspects of physics found on the floor. The gymnast performs on a floor that "measures 12 x 12 meters, with an additional safety border of 1 metre. The performance area must have a surface elasticity, to allow for power during take-off and softness for landing." (FIG) The surface elasticity found in the floor mat gives the gymnast extra bounce which increases her momentum.
Let's examine a basic tumbling run. All three of Newton's Laws can be seen in this one tumbling run. We can see Newton's first law before the gymnast takes even one step. Until she takes a step, the gymnast is at rest. When she is ready to tumble the gymnast applies the force. A gymnast takes a running start when approaching a tumbling run, and as she is moving across the floor she is increasing her momentum. This is a demonstration of Newton's second law.
Newton’s second law states that when a net force is applied to an object, that object will experience a change in velocity, and will undergo acceleration. That acceleration is proportional to the net force applied, and inversely proportional to the mass of the object. In other words, the heavier an object is, it will require a greater force to move the object the same amount (e.g., distance) as a lighter object. ( https://www.grc.nasa.gov/www/k-12/airplane/newton2.html)The mathematical equation that expresses Newton’s second law is:
Newtons second law can be indentified more easily using the equation F=ma. This is an equation that is very familiar to those of us that wish to do well in any physics class! This equation tells us many things. First it tells us the net force that is being exerted on an object, but it also tells us the acceleration of that object as well as its mass. The force on an object is measured in Newtons (I wonder where they got that from). One Newton is equal to one (kg)(m)/s^2. For example, if superman pushes on a 10,000kg truck and it is moving at a rate of 2m/s^2, then the force that superman is exerting on the truck is 20,000N. For those of us that wish to move on in the field of physics, Newtons second law (F=ma) will forever haunt us!
This law is also often called “Inertia”. Inis the tendency for an object to resist the change in motion. Like, if you are moving and nothing happens to you, then you will keep moving. Forever. If nothing is happening to, and nothing is trying to put any type of force on you then nothing will happen .Forever. (Newton’s Three) There is a limit that must be met in order for the first law to be suitable to any given motion. The limit is represented by the phrase "... unless acted upon by an unbalanced force." As the long as the forces are balanced - the first law of motion
...ys that for every action there is an equal and opposite reaction, and this is also displayed when a bat hits a ball. The bat exerts force on the ball, just as the ball exerts force on the bat. This force can sometimes even be enough to break the bat, like in the illustration below.
In this case, I will be talking about basket tosses. Extreme care needs to be taken for this stunt to be completed safely and successfully, meaning there are many rules and regulations set in place (AACCA, 2016). In fact, some competitions discourage them in routines due to the high rate of serious injury. The physics concepts that I will be explaining will involve the whole execution of the skill from the time the flyer is in their hands to the time that she is caught by her bases in a cradle. Concepts such as Newton’s first law will explain how they get her into the air. The use of torque will explain her rotation along with angular momentum. Finally, gravity explains her descent back towards the earth and the impulse momentum theorem describes the most critical part, the
Here mass, acceleration, momentum, and force are the quantities that are defined externally i.e. they are the externally defined quantities. It is also equally true that Newton’s laws of motion do not suffice to characterize the motion of deformable and rigid bodies. After the generalization of the laws of motion propounded by Newton in 1950 by Leonhard Euler, the laws were equally accepted for rigid bodies, and this was later called as Euler's laws of motion. This theory was later applied in the deformable bodies, and the laws were equally true in that condition, as well. Even though this law is outmoded by laws of relativity, this law is equally applicable in the situation where the speed of objects are less than the speed with which light travels.
Newton’s three laws of motion state that: 1. an object’s state of motion tends to remain constant, unless an external force is applied. 2. The force applied to the object is equal to the mass of the object multiplied by its acceleration, and the force and acceleration vectors are in the same direction 3. For every action, there is an equal and opposite reaction. When considering these laws in the analysis of a hard collision in football, we make a few observations.
Force is a push or a pull, which can make an object start moving when
The sheer energy of a gymnast alone can be felt by audiences of all ages, but what the spectators lack the ability to feel is the pounding of the bodies that bear the impact of the athletes in action. Gymnastics consists of a mixture of acrobatic performances of four different events for females, and six different events for males (Gianoulis 1). Gymnastics is demanding in a multitude of ways, including: physically, emotionally and mentally. It requires countless hours of dedication. The concerns of most gymnasts are moving up to the next level, or getting a more advanced skill, while the concerns of the doctors, coaches, and parents revolve mostly around the athlete’s health, which is put at stake for the adored yet dangerous sport. Injuries are common among both male and female gymnast alike, but due to the fact a female gymnast’s career peaks at the same time of major growth and development, a female gymnast’s body as a whole is more likely to undergo lifelong changes or affects (Gianoulis 2). Among the injuries of the mind blowing athletes, the most common ones affect the ankles, feet, lower back, wrist, and hands of individuals (Prevention and Treatment 1). From sprains, to the breaks, the intriguing sport of gymnastics is physically demanding on a gymnast’s body.
As you can see there are several problems that lye within the gymnastics society, but we the outside force must come to learn, understand and teach the athletes and coaches some of the correct ways in which they can handle situations. I have come across some major problems throughout this paper, along with some good solution which I hope everyone can take into account. It is important for not only the athletes of this country to be aware of the problems they have, but also to inform the rest of society about the situations hence forth. I know things can change when we put our minds together and create action upon our solutions. I hope this information has helped anyone who was having a difficult time understanding some of the issues that arise with gymnastics, or anyone who had a question. “ Don’t let a problem or situation get in the way of a dream.”
Running is a natural form of human locomotion. To many, running is an essential aspect of most sports and is also a simple way that requires little to get exercise anywhere. But because many people have adapted to improper forms of running over time, numerous physical injuries are the results. With the help of understanding the physics behind running, people can learn to run in such a way that expends less energy from the body. Keeping physics in mind may also lead to less injuries and effortless running. Remember, physics can be very helpful when running!
If a force acts on a body, the body accelerates in the direction of the force. In the example of the force of gravity, small things like textbooks are pulled downward toward the center of the large mass of the Earth, not up into space, even if some people think that this might happen. Isaac Newton was the first to conceive of weight as the gravitational attraction. between the body and the Earth. The force that results from the gravitational attraction of the Earth on its surface is what we call weight. Science has chosen to measure the mass of objects in units that are roughly equivalent to the weight of those objects on Earth.
Physics is a part of everyday life. It is evident in the modern technological devices we use in every day experiences and objects around us. Although physics is understood to be only useful in the classroom, physics can also be applied to one the most popular activities on the planet, basketball. Whether jumping for the ball, or leaping for a slam dunk, the human body follows the same laws of projectile motion as do other objects. The sport that includes shooting, passing, running, and dribbling involves topics covered in physics such as force, friction, effects of air resistance, velocity, air pressure and energy. Basketball also involves factors such as projectile motion in making a basket, gravity and its effects on passing and dribbling, and Newton’s First and Third Law on passing and a number of others.
The second law is, “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” The heavier object requires more force to move an object, the same distance as light object. The equation gives us an exact relationship between Force, mass, and acceleration.
My heart is beating rapidly. I am filled with trepidation. Can I perform? Will I remember my routines? Will I stick the landing? Will I keep my legs straight? What if I fall off the beam? What if I disappoint my coaches? What if I’m not the best? What if…?
