Essay on Physics of Soccer
Physics of Soccer I. Introduction Soccer is a sport that's very challenging and during the course of this semester I've found physics can also be
described as challenging. As far as I was concerned soccer and physics were both challenging and that was all they had in common, consequently upon
researching them both this semester I found that I was wrong. For me this was nothing new because I've found that physics isn't a subject that can be
skimmed, but rather it has to be studied to the finest detail. Those small details if missed can make all your efforts worthless. Or on the positive side
understanding those details can make your efforts worth it in the end. And in soccer if you understand the physics, which to most players...show more

Defensively in soccer speed is sometimes slowed down and skilled footwork may be needed. How a player uses speed or velocity depends on the
situation, but if just one isn't done skillfully a player may not end up making the play as planned. III. Distance The distance that you are able to
kick the ball can be summed up with the equation for distance, d=RT, distance equals rate multiplied by the time. So speed and time are both very
important when kicking the ball because it directly affects the distance. Soccer players vary the distances that they want to kick the ball. Skilled
players can estimate very quickly how fast to make the ball move to make it go where they need it to. Before learning this equation in physics I just
thought you kicked the ball, but now I know that when this equation is applied to soccer it means so much more. Soccer players can use this to help
them judge how hard and fast they need to be able to kick the ball to make it go a certain distance. This is just another example of how physics, the
small details, can be used to improve ones soccer skills. IV. Momentum Momentum can be defined as the product of the inertial mass and the velocity,
p=mv (Kirkpatrick, 106). When relating this equation to soccer it can be directly interchanged with the mass of the player and their speed/direction. So
a player must be not only quick, but have the mass to gain the momentum needed. When the

Essay On New Physics
Research Statement Zhen Liu
What is the (next accessible) scale of new physics? We do not have a clear answer. We are living through a challenging and exciting era, in sharp
contrast to the situation of the past (half) century in physics. The discovery of the Higgs boson, the determination of the non–zero Оё13 neutrino
mixing parameter, the first detection of gravitation waves, and many greatly improved experimental probes for new physics beyond the standard model
mark the great triumphs of our understandings of nature. Profound puzzles of nature, such as hierarchy problem, dark matter, neutrino properties,
matter–antimatter asymmetry, strong CP, flavor structure, etc., are actively being explored but yet remain to be solved. However, no

Currently, I have been working on the intriguing potential for new physics through novel on–shell interference effects between signals and background
at different scales to probe BSM physics, and exotic long–lived particle signatures at the LHC. Given the long–term planning

Research Statement Zhen Liu September 2017 necessary for next–generation experiments and the exciting journey ahead of particle physics, I have
been working on physics cases for various future collider scenarios, including the ILC, CEPC, FCC–ee and a muon collider. As an active junior
member of the community, I also have been contributing to various community reports, including the 2013 Snowmass reports and recent Higgs Yellow
report and currently involved in the writing of the long–lived particle white paper and various design reports for future colliders. I recently have been
appointed a co–convener of the Higgs exotic decay subgroup of the LHC Higgs cross section working group (LHCHXSWG), bridging the theoretical
and experimental community in searching for non–standard Higgs boson decays.
My research interests and experience in BSM phenomenology cover a large span of topics. My research on Higgs physics ranges from Higgs precision
at various colliders, exotic Higgs decays, Higgs EFT, probing first–order electroweak phase transition via the Higgs boson, to composite Higgs physics
tests in the scheme of low

Reflection On Physics
I wish I could start by saying that I have always loved physics. I didn't. In fact, I hated physics in the 9th and 10th grades, not because I didn't like
doing science or was bad at mathematics, but because I was unable to understand the equations, that appeared to come from nowhere. According to my
physics teacher, both of the equations for a vertically thrown ball y = 1/2gt 2 + v 0 t and y = в€’1/2gt 2 + v 0 t were correct, which didn't make much
sense to me because the signs were different!
However, my view on physics changed dramatically, when I started taking un– dergraduate physics classes in the summer vacation of 10th grade by
signing up for a distance learning program. Not knowing much either single– or multivari– able calculus,...show more content...
I started with the elliptic beta integral proven by Spiridonov and took appropriate limits to arrive at new equation, which I wrote with the help of my
supervisor as a new solution to the YBE. We are still in the process of writing a paper about our discoveries. I have learned a lot of new techniques
and physics during my time at the insti– tute. Most importantly, I met a new side of physics; researching. I usually did not have to spend more than
couple of hours before I have solved a problem on a problem sheet. Researching was a completely different experience; the prob– lem that I tackled did
not admit a solution for weeks, even though I worked intensively every day. Upon having realized that I have solved the problem, my heartbeat
increased and I felt an ecstatic sensation through my spine and my whole body; I discovered something nobody on earth knew before and thus,
extended the boundaries of human knowledge.
I have always liked discussing physics and mathematics with my friends at the university and in particular, helping them with the subjects, with which
they had problems. Hence, I decided to become a teaching assistant (TA) for the Analysis 1 lecture in the 3rd semester and later for the Analysis 2
lecture. Cur– rently I am a TA for theTheoretical Physics 3 (Electrodynamics) lecture. As a TA I presented the solutions to the problem sheets on a
blackboard for an exercise group of 20 students. In the

Just about everything you do from moving to eating to listening to music involves physics. Now that I have really explored them I think it is hard to
go about our day and not do something that involves physics. Some of the things I will talk about are getting out of bed, the eye and how eye glasses
help a person see better, speakers, the Frisbee, sailing, and the pulleys I use to get my jeep unstuck in the mud when I ride in the woods. All of these
require energy, and energy is what physics is all about. There is kinetic energy,potential energy, conservation of energy, velocity, acceleration, mass,
force, and gravity. Energy gives you the ability to do work. Energy is everywhere in nature...show more content...
Conservation of energy is...TE = PE + KE + WE; where total energy is made up of potential energy, kinetic energy, and work energy. Your total
energy is conserved while walking. The potential energy is the biochemical potential of your muscles and frame, which is converted by work into
kinetic energy, which is the walking part. From a standing still point you need TE to total energy to push off with your foot. You need that force
because the 1st law says your body is lazy and won't move unless pushed. But once you get going you can reduce that force a bit because his law also
says once you get going your body wants to keep going. In fact, if you want to stop, you'll need to exert some force to do that.
The force to stop comes from the static friction of your foot or shoe against the bottom material it is on, such as a floor or cement outside. That
creates the opposite reaction of Newton's third law and as that force pushes you forward. While the forward momentum is going on you also have
the force of gravity to deal with as well as keeping your balance. I looked into the physics of the eye itself and into corrective lenses because I wear
glasses. The human eye is a very complex piece of anatomy. Like a camera, the eye is able to refract light and produce an image that can enable
someone to see. The eye is an opaque eyeball filled with liquid. In the front of the eyeball is a transparent opening known as the cornea. The cornea is

Physics of a Car Essay
Physics of a Car
The average driver doesn't think about what keeps their car moving or what keeps them on the road, but that's because they don't have to. The average
driver doesn't have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car's tires around a
turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are
an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but
function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in...show more content...
Negative lift is created by front and rear wings on race cars and by ground effects and spoilers on the average sports car. Most negative lift is used
to fight inertia as a car rounds a turn. Inertia is the tendency of an object to remain in the same state of motion (Murphy 77). When a car rounds a
turn at high speeds it often needs more force than it's weight to resist the car's tendency to keep traveling straight. The increased downforce puts
more weight on the tires helping the tires grip the road. Drag force is the cost of increasing downforce. Drag force is the force acting on an object in
motion in the opposite direction the object is moving through a fluid (Yager). To most people drag force is simply known as air resistance. The
objective of aerodynamic efficiency is to maximize downforce while minimizing drag force.
Acceleration and Speed are obviously the two defining characteristics of a fast car. Newton's three laws of motion are an essential part in
determining how fast a car will accelerate and how fast it will go. Newton's second law is the easiest to understand in relation to a car's acceleration.
Newton's second law mathematically states Force=(mass)(acceleration) (Murphy 78). This law explains why cars that need to accelerate fast should
be relatively light in weight compared to other cars. Removing mass, such as a bumper, radio or fancy upholstery reduces the weight of

Quantum Mechanics Essay
Quantum Mechanics
Quantum Mechanics is the science of subatomic particles and their behavior patterns that are observed in nature. As the foundation of scientific
knowledge approached the start of the twentieth century, problems began to arise over the fact that classic physical ideas were not capable of
explaining the observed behavior of subatomic particles. In 1913, the Danish physicist Neils Bohr, proposed a successful quantum model of the atom
that began the process of a more defined understanding of its subatomic particles. It was accepted in the early part of the twentieth century that light
traveled as both waves and particles. The reason light appears to act as a wave and particle is because we are noticing the...show more content...
This observance is what Werner Heisenberg refereed to as the principle of uncertainty, which commonly became known as Heisenberg's Uncertainty
Principle. We have the illusion that position and momentum can co–exist in large objects whose inherent action is huge compared to subatomic
particles. Heisenberg realized that the uncertainty relations had profound implications. Heisenberg set himself to the task of finding the new quantum
mechanics to explain what his theories observed. He relied on what can be observed, namely the light emitted and absorbed by the atoms. By July
1925, Heisenberg wrote his answer in a paper. The basic idea of Heisenberg's paper was to get rid of the orbits in atoms and to arrive at new
mechanical equations. Heisenberg's approached focused mainly on the particle nature of electrons. The mathematics Heisenberg used were tables
commonly used for multiplication of arrays of numbers–mathematical objects known as matrices. Using the mathematics of matrices, scientists had at
last a new mechanics for calculating the quantum behavior of particles. Heisenberg, and others showed that the new quantum mechanics could account
for many of the properties of atoms and atomic events.
Most physicists were slow to accept matrix mechanics because of its abstract nature. Erwin Schrodinger came up with a mathematical equation which
nicely described the wave nature of electrons. Scientists gladly

Becoming a Physicist
In the present, science has grown to become a great role in our lives. We can attribute many ordinary things in life that we know now to science.
Physicists are the ones that study the structure of matter, space and time. An example of a physicist would be Einstein, or Newton. This paper will
discuss the education necessary to become a physicist, the skills that physicists need, and the earnings, as well as the benefits/risks of the job.
The education of a physicist starts young. At any age, one requires creativity and curiosity devoted to their pathway. From there, Dr.Michio Kaku states
the physical learning begins. In high school, he thinks the best opportunities lie in physics books and science fair projects. (1) These practices
introduce you to basic physics. If needed, an interview with a physicist can help devote your passion to the job. A basic math knowledge is
required so Calculus and other math classes will aid the journey. Also, good grades throughout the four years in high school as well as high SAT
scores helps for admission into the best schools. In college, the best option is to stay all four years. In sophomore year, students typically have to
choose a major to focus on, and that's when aspiring "physics majors should begin to think about doing (a) experimental physics or (b) theoretical
physics and choosing a specific field" ("Kaku 1"). After that, it will take at least a Bachelor's degree to become a physicist. Getting a Bachelor's degree
takes about 4

Essay on A Century of Physics
A Century of Physics
By the end of the nineteenth century after more than two thousand years of intellectual struggle that began with the Greek philosophers, physical
scientists had reason to believe that they were beginning to understand the universe. Their theories of matter and energy, of electricity and magnetism,
of heat and sound and light were confirmed in laboratories throughout the world with increasing precision. Experimentation was the method and
mathematics the language of a powerful coherent body of knowledge called classical physics. For a few years before and after the turn of the century, the
world was taking a breather from war and rebellion. The monumental achievements of science, technology, and industry...show more content...
The chance discovery of radioactivity finally signaled the beginning of a new era in physics. As the element polonium, identified by Polish–born Marie
Curie in 1898, emits radiation it changes spontaneously into lead. This discovery shattered the belief inherited from the Greeks that the elements are
immutable and their atoms indestructible.
What causes atoms to decay?
What are they made of?
What forces are at work inside them?
Such questions were new to physics, and were to remain at its cutting edge throughout the twentieth century. The answers would affect our lives in
ways no one could imagine in the year of 1900.
The twentieth century began with a flurry of innovations such as the airplane, the mass–produced automobile, and transatlantic radio communication.
They transformed the world, but the changes sweeping over physics at the same time were far more radical. Those brought about not just different
lifestyles, but new ways of thinking. Modern physics grew out of classical physics and rest of three pillars: the quantum theory, which describes atoms
and their nuclei, Special Relativity, which deals with the relationship between space and time and General Relativity, which explains gravity. The latter
two were the sole creations of Albert Einstein and even the former received a crucial

The History of Physics Essay
The History of Physics
In order to attempt to trace the origins of the modern science that we now refer to
as "physics," we must begin with the origin of the term itself. Taken from the Greek
word "physika" meaning growth or nature, physics most obviously began as the
intelligent study of the human environment (Webster 393). From superstition and
religious practices, the foundation of all other sciences was born. These concepts have
subsequently grown into what we regard today as physics.
It can be easily argued that the earliest evidence of mankind's scientific
assessment of the physical world can be traced to the Babylonians. In all
probability, the Babylonians had the first written language...show more content...
The discovery of
the studies and technologies of these previous cultures does in some regard require a
glance farther back.
A Greek philosopher named Herodotus supposedly reported that Pythagoras lived

in both Egypt and Babylon where he studied mathematics (Lindberg 13). It is impossible
to determine whether this is historical fact or merely legend. It would be extremely
difficult to ascertain exactly how much of the Greek's thinking was influenced by such
cultures; if in fact it was influenced at all.
Many texts choose the ancient Greek port of Miletus as the beginning of the
discovery of nature that we commonly think of as the original physics. The town of
Miletus is credited as the home of a Greek philosopher named Thales and what is know
of Thales is taken from the writings of Aristotle (Spangenburg 8). Thales is considered
to be the first example of a person leaving supernatural explanations in an effort to better
understand the natural world (Lindberg 29). If Thales of Miletus recorded any of his
own ideas, none have survived. At least none have yet been discovered.
Anaximander, another Greek philosopher, was a student of Thales and expressed
a belief that all life originated in the

Essay about The Physics of Car Collisions
Basic Concepts
Issac Newton was the first to state the concepts that are necessary to understanding the physics of collisions. His three laws are used again and again
in all the fields of physics:
Newton's 1st Law
In the absence of external forces, an object at rest remains at rest and an object in motion remains in motion with a constant velocity.
This law can be best observed in space, far from the gravity of a star or planet, where there is no friction or air resistance. If, in the middle of deep
space, you give a rock a little push, it will continue with the direction and velocity you gave it forever. The only way to stop it is to apply a force in the
opposite direction. This law is not intuitive because we are surrounded...show more content...
Every single action has an equal and opposite reaction. If you were standing in the middle of a perfectly slick frozen lake, and needed to get off, you
could throw an object away from you. When you applied force to the object you threw, it also applied an equal force pushing you back. You would
travel in the opposite direction from the throw, although slower, because you probably havemass more than the object you threw.
Static and Kinetic Friction
Friction is a key concept when you are attempting to understand car accidents. The force of friction is a force that resists motion when two objects
are in contact. If you look at the surfaces of all objects, there are tiny bumps and ridges. Those microscopic peaks and valleys catch on one another
when two objects are moving past each other.
This explanation is a little simplified. There are other processes at work, including chemical bonding and electrical interactions.
The level of friction that different materials exhibit is measured by the coefficient of friction. The formula is Вµ = f / N, where Вµ is the
coefficient of friction, f is the amount of force that resists motion, and N is the normal force. Normal force is the force at which one surface is being

pushed into another. If a rock that weighs 50 newtons is lying on the ground, then the normal force is that 50 newtons of force. The higher Вµ is, the
more force resists motion if two objects are sliding past each other.
There are

Physics Of Light And Light
Through the fields incorporating the science of light, astronomers use factors such as wavelengths to interpret stars' temperature, heat, distance, size,
mass, density, etc. To obtain all of this information certain light gathering instruments must be used. These instruments include telescopes. To record
this information spectrographs are also mainly used to record the spectrum and dispersion of light. In light there are different waves and particles. Light
is made up of electric and magnetic fields. Due to this fact, light is an example of electromagnetic radiation, it is the changing of these fields to travel
through space shifting energy maneuvering from one area to another. Since light is an electromagnetic wave, each one has a certain wavelength.
Telescopes help us to view the visible light of the electromagnetic spectrum. Most of the electromagnetic spectrum, such as infrared, x–rays, ultraviolet,
and gamma rays, don't reach earth's surface to be examined. A telescope in space, above the atmosphere, however, is said to be diffraction limited.
Since the speed of light is constant a wavelength of radiation of a star can be seen as its frequency. Frequency is recorded based on a certain number
of waves emitted within a brief second.
Optical Telescopes have two types: reflecting and refracting. In 1609, Galileo had developed the first telescope. From here on out, ideas back then of
the geocentric solar system were finally put to rest through the use of the first
