Physics in Slingshots





Abstract- Slingshots are simple devices that are used to launch a small projectile, although appearing very simple in function slingshots utilize a number of physics principals. The drawing of the sling back represents Hooke's Law due to its elasticity. Once finding all the factors of force and velocity the findings are used in determining projectile motion, and determining on the angle that the projectile is launched one can find the range of the slingshot.

Abstract
            Hula hooping is one of the great childhood pastimes, beloved by kids all over the world as a schoolyard staple. A simple toy, just a large, hollow hoop, usually lightweight plastic, balanced in rotational equilibrium around someone's hips. Sure it seems easy enough to master the motion, but have you ever stopped to think of the physical mechanics of the process?  By all logical reasoning, a hula hoop should fall to the floor, due to the effect of gravity, so why is it able to stay rotating around your hips? Many physics concepts are at work in the efforts of hula hooping, such as centripetal force, friction, inertia, and torque. I explore these concepts and more in my paper linked below, “The Physics of Hula Hooping”.

Abstract: 

Basketball is widely considered as one of the most popular sports in the world in today's day and age, and the number of people today who participate grows every single year. While the idea behind basketball and its rules may be considered straight forward and simple by many, there are many ways in which physics, and science is taken into consideration with the basic fundamentals of the sport. In my research, i will explain the basic fundamentals of basketball, and how that ties into many different types of physics concepts. Those being Projectile motion, linear motion, Inertia, backspin, and of course, gravity. I will be demonstrating how each of these physics components tie into the game of basketball, and how each effect the sport and a number of different ways. The basic skills of jumping up for a shot, or the backspin put on the ball when shooting are both examples of ways physics plays into the basic aspects of the sports, without natural realization from those who play!

Physics in Frisbee

Works Cited

Abstract: Frisbees are a common source of entertainment and sport. They operate under the physical concept, aerodynamic lift. When flying in the air, a Frisbee can be viewed as wing, with Bernoulli's Principle controlling the magnitude of the lift force which keeps it in the air. The different forces applied are not centered on the disc though, so angular momentum is needed to prevent the disc from flipping over. This angular momentum resists the torque caused by various forces.

The Physics Behind Gymnastics

Works Cited

Abstract 

Gymnastics is a highly competitive sport, demanding strong skills in speed, strength and agility from relatively young athletes. While the extreme tumbling passes and balance may be considered impossible for any average person, basic laws of gravity and force presented through the principles of physics, explains why gymnasts are able to execute these tricks safely and accurately each time. In this paper, basic apparatuses are covered through their relation to specific physics concepts. First, comes the relation of Newton’s laws regarding force, acceleration, and motion through the uneven bars and balance beam. Then, the paper will explore how angular momentum and torque allows for the proper rotation that is demanded in the vault apparatus and is also demonstrated during floor routines. Through these explanations, the seemingly unfeasible events become easier to understand through basic physics concepts.

PHYSICS IN LACROSSE





Abstract: Lacrosse is one the fastest growing sports in the world. Originally played by Native Americans this contact sport now has its own professional league and is played throughout many collegiate and high school levels. The game involves sticks in which the player uses to catch and shoot a ball into the opposing teams goal. While many players may not notice, lacrosse is found to have many signs of physics within the sport itself. Newton's Laws of Motion can be found with the ball and collisions. Another example would be torque and lever when passing and shooting. Friction is also found in the lacrosse sticks. Physics is very much apparent in game and can help educate you more about the sport of lacrosse. 

The Physics of Car Collisions

Abstract

While car collisions are certainly a scary scene, having knowledge about the physics involved with them could reduce the terror. In my research, I will be explaining four key concepts highlighted in car collisions, including linear momentum, impulse, inertia, and collisions. Beginning with inertia, I will remind you of Newton's Laws of Motion and express the effects of inertia on the passenger during a car collision. I will also add the significance of the application of impulse when talking about inertia. I then describe the different types of collisions, giving direct examples of each in the context of car collisions. Building immediately off collisions, I will evaluate linear momentum, its principles, and its application to the conservation of energy in collisions. Knowing and understanding these simple principles of physics is vital not only for your own safety (and your cars!), but for the safety of all those around you. All information found in my research came from numerous sources and can be found in the "Works Cited" page, listed above.

The Physics of a Catapult

The Physics of Catapults

Abstract:
Since 400 BCE, the development of heavy artillery has developed tremendously. However, everything from tanks to fighter jets originated from one simple war machine: the catapult. A catapult consists of a bucketed arm attached to a frame by an elastic string. While the idea of a rock throwing machine appears quite elementary at first glance, the amount of damage a catapult can cause is rooted in its physical properties. The mass of the arm, the mass of the load, the angle of the arm and the tension of the string all have a direct impact on the damage this device can inflict. In my project, you will reveal the secrets to utilizing the concepts of physics to find out just how devastating a simple machine can be.

Dance in physics

Abstract:

Physics plays an essential role in dance.  Dancers need to rely on the laws of physics so they can be better dancers overall.  The laws of physics can help a dancer turn faster, jump higher and balance longer.  If a dancer were to not follow the laws of physics, they could potentially get hurt and ruin their career.  Momentum is a very important part of dance because dancers need momentum when turning and in some cases, jumping.  Myself along with my dance peers follow these laws precisely.  We are now able to balance longer because of the laws of gravity.  Now, more people can understand how dancers do what they do but still be amazed.  

Physics of Dance


For this project, I decided to study certain dance moves and find their relations to the concepts we learned throughout the year in physics. I used specific steps from ballet, a dance that I have done myself for years. It was really interesting to see that physics can be applied to real-life situations and movements I do almost everyday. For this project, I will study the movements of three different dance moves, pirouette turns, grand jetés, and finally, fouetté turns. A pirouette turn challenges the concepts of angular momentum, using one’s momentum of inertia multiplied by the rate of spin. Grand jetés are associated with horizontal and vertical motion, as well as center of gravity. Fouetté turns deal with perpetual motion and momentum.

physics of bungee jumping





Bungee jumping is a thrilling experience that not many choose to do in their lifetime. 
In the first phase of bungee jumping, when the bungee jumper falls down,  the bungee rope is still slack. In instructional material this phase is often considered a free-fall, but when the mass of the bungee rope is taken into account, the bungee jumper reaches acceleration greater than g. The bungee jumper jumps off a tall height such as a crane or a bridge and then falls vertically downward until the elastic bungee cord slows his descent to a stop, before pulling him back up. The jumper then oscillates up and down until all the energy is dissipated. In this whole process many forces are in progress. the weight of the person and the height that the person is jumping off of have to be taken into account, along with many other things to truly understand how bungee jumping works.

Frisbee has been a fun activity enjoyed by many and has spawned new sports like disc golf and ultimate frisbee. Frisbee looks like a simple activity but when you take physics into account it becomes much more. From Newton’s first three laws to Bernoulli’s principle this activity or this plastic disk is much more complicated than meets the eye. The physics of Frisbee can be explained through two physical concepts, aerodynamic lift and gyroscopic stability.   Yet, knowing the physics behind frisbee can prove advantageous on the field.

I have decided to research the physics behind this device, how it's internal parts function, and how we can hear different frequencies and volumes from them. When you finish reading my findings, you will understand how circuits, magnetism, vibrations, and sound waves can all work together to produce your favorite song.

Physics and Figuring Skating: How Are They Related?





Abstract

When figure skaters are on the ice, one can see that they spin faster when they hold their arms to their bodies rather than when their arms are extended. Do you ever wonder why that happens? In order to understand how figure skaters are able to move so swiftly at some times but slowly at others, it is important to understand the role which physics plays in the sport. Throughout my paper I will explain how figure skaters are effected by physical principles, such as rotational inertia. My paper will start with a background explaining some of the most common figure skating moves. Then, it will go into how each of those moves is affected by the physics concepts we learned throughout the year, such as angular momentum and friction.

Abstract:
Dancing is the oldest form of which people express an idea or emotion. It requires a series of movement that match the speed and rhythm of a piece of music. It also requires the knowledge of physics. This allows teachers the opportunity to teach physics in a motivating way. Physics can be seen in dancing from different perspectives. It can be seen in turns, balance, jumps, etc. Today I’ll be illustrating how physics plays a very important role in dancing.

The Physics of Bowling

The Physics of Bowling



Abstract
Did you know that the sport of bowling entirely involves physics? Well if you didn't know that, you should read this blog post about the physics incorporated into everybody's favorite sport to play at night on the weekend.
Bowling is a simple sport. First, grab a bowling ball with a weight that you're able to carry. Then, you approach the lane and aim your roll so you don’t miss the pins. Next, you roll the ball with force and accuracy. Last but not least, you hope that the force, speed and inertia applied on the ball knocks all the pins over.
Here are some scenarios in which physics is present in bowling. First, a bowling ball will slow down as it’s going down the lane due to the friction present between the ball and floor. To add on, bowling involves both somewhat elastic and inelastic collisions. Bowling also involves the conservation of momentum within the ball and pins. Moreover, Newton's Three Laws are very much a part of bowling physics. Lastly, inertia plays a great role in the way bowling is, as there's inertia in both the ball and pins. 
The sport of bowling is all about physics. To learn more about it, read my paper and view my slides to gain a better sense to how your knowledge of physics can change your viewpoint on the sport.

Physics In Soccer 

    

Abstract 

Soccer is easily the most watched and played sport all around the world. Although most people play the sport for fun, what they fail to realize is the amount of science that goes into playing the beautiful game. At a young age most kids are taught to hit the ball with power, yet they don't understand why it is they do it, and its scientific effects. The same goes for one someone kicks a soccer ball to curve it. Whether you're on a field, in the gym, or on the streets there is science in soccer everywhere. Whether it be Newton's Laws of Motion, Momentum, The Magnus Effect, Friction, or Projectile Motion science affects the way a ball is shot, passed, or dribbled. To inform you of the science in Soccer, in my research paper and slides you'll see each aspect of science evaluated. All information for this project that was used can be found in the "Works Cited" page in my research paper or slides.

Abstract
Have you ever been at a baseball game and watched as some players hit home runs and others could barely make contact? Or why despite the pitcher's team or whether they were lefty or righty, they all generally follow the same motion? This project will go in depth into the physics behind baseball. You will learn about which types of pitches are easiest and hardest to hit, the motions a pitcher should follow to gain maximum control over the ball, and much more about how a ball's spin impacts the batter's ability to hit it. I will go through the common pitches such as fastballs, curveballs, and knuckleballs as well as how to throw them, and why some may be hit farther and others not as far. I will also discuss other forces that impact a ball's motion, like drag, gravity, Magnus force, normal force, and frictional force. My research also discusses the difference between centerline angle and attack angle and how depending on where you hit the ball, the ball's motion will be impacted. I used a variety of sources for my research that all can be found in the "Works Cited" page in either the research paper or the slides presentation.

Abstract:

Ever wonder just exactly what happens when your on a rollercoaster. How you are going the speed you are going? How you have enough energy to get over the next hill? In my research, I will be explaining a variety of ways the subject of physics relates to rollercoasters. Beginning with energy, I will bring back the concept of the conservation of energy and explain the substantial role it plays through your ride of fun. After that, I will break down the fastest parts of the coaster before you even get on a based off of types of energy depending on where exactly the car is located. I will then continue to analzye rollercoasters by explaining their predictable structures based on insuring that the car continues to move without any artificial help. Building off of artificial help, I will explain exactly why certain belts are placed in certain locations and the importance behind them. After the ride is over, I will dig into the idea of friction and its purpose in stopping the ride for you in the exact spot you want it to. Lastly, to finalize my report I will explain the fallen. Not the ride following backwards, or the people who have died on rollercoasters but instead the rollercoasters that didn't work. Mainly because they forgot to think about physics! All information found in my paper came from numerous reliable sources and can be found in the "Works Cited" page, listed above.

Physics of Quadcopters


Abstract
Drones have been around for a long time. They first appeared in the early 19th century and since then have become more efficient in the amount of space they take up, more complex in their build, and yet more easy to operate. Operation of quadcopters is achieved with the help of motors, propellers, and an accelerometer and gyroscope. These are components that take many different forms, but in electronics, they take advantage of several laws that have been discovered relating to capacitance, and use this to determine what is happening and stabilize themselves. Quadcopters have tremendously bright futures, from transportation to exploration to recreational fun.

Abstract:
Hockey is a game that requires a ton of physical and mental skill.  This is due to the fact that everything is happening at such a fast rate, that you must be able to keep up with.  Now while the players may not realize it, this is all happening due to the amazing world of physics. I will get more into it during the paper, but what you must know is that players are able to stay skating due to the friction created between the ice and the skates or the puck and the ice which allow for players to be able to maintain their momentum. Players need to be able to realize how much force to put on a shot or pass by considering how much the puck weighs and how much acceleration to hit the puck with, which then creates an inelastic collision. The slapshot is an important part of the game as it is able to confuse goaltenders due to the torque that is put on the puck when shooting. Also, while playing hockey, Newton’s 3 laws are all in full affect, whether its shooting the puck, the puck itself or just simply hitting into another player. I hope you enjoy my research and learn as much as I did about the amazing world of physics in the amazing world of hockey.

Lastly I explain the magnus effect and its role in scoring a goal. Knowing these things you should learn more about the science behind soccer that makes it possible as well as helping you improve in a game.  

The Physics of Figure Skating


Abstract:
This paper investigates the physics that allow the motions and moves of figure skating to exist. Starting with its origin in Finland the paper explores how ice skating change from a form of transportation to an artistic sport. It covers the main principles that allow skating including friction and inertia. It then covers the more advanced topics that allow what is now considered as figure skating. Angular momentum and projectile motion allow throws and spins. When you understand conservation of momentum you can work to maximize your number of spins and your velocity. This paper will explain how figure skating is possible through multiple physical principles. Without understanding the principles of physics it can be difficult to fully understand and appreciate the beautiful moves in skating. Information from this paper comes from multiple sources that can be found in the works cited page.

Abstract

Have you ever wondered how a guitar works? Guitars are amazing, versatile instruments that can produce a variety of sounds and tones. In my presentation I explain how a guitar makes sounds in terms of physics! I explain how the tension on each string corresponds to the frequency of the sound that each string makes. These frequencies are called harmonics. The vibrations that occur when you strum a string resonate through the wood of the body of the guitar and different woods have tonal differences.

Abstract:
Golf is a game that requires not only a lot of physical skill, but requires a lot of knowledge on the topic of physics. We will get more into the details in the actual paper, but the ball is hit in an elastic collision, in which the ball is bounced off the club in order to be hit further. Using the basic equation F = Ma, the more you accelerate the clubhead or swing it fast, the further the ball will go. Also, applying the concepts of torque, your ball will go further if you take a full swing, use a longer length club, and swing harder. But golf isn't all about the aggression, but finesse as well. One must hit the ball perfectly square so it goes straight, rather than way left or right. Golf requires a lot of skill and practice, and applying the concepts of physics, you can improve at the game of golf.
