The Physics of the Hyperloop

 Have you ever been on a flight or on the train wondering why it was taking so long? Have you ever wanted to see your family all the way across the country but you can't because of the price? Well the Hyperloop can change your travel plans completely. The Hyperloop is one of the greatest ideas ever forming into a creation in front of our eyes. Combining speed and safety, the Hyperloop is a capsule that is suspended in the air inside of a tube, meaning it has no friction and uses purely air pressure making it go forward. Created by Elon Musk in great detail, the Hyperloop should have the potential to travel at speeds up to 755 mph, which is faster then most commercial airplanes. This invention will also be cost effective only projected to cost 6 billion dollars to make nationwide. The Hyperloop is projected to be fully completed by 2020. Being able to travel through the biggest cities around the nation, the Hyperloop will be the best mode of travel yet. 

My project was based off the physics of figure skating. Who ever knew figure skating included so many different laws! Newton's three laws play a huge role in the figure skating. They create the ability for the skater to be able to glide over the ice and preform lots of different cool tricks. Newton's first law is the reason we are able to glide over the ice for a period of time and eventually come to a stop. Newton's second law plays a role in why acceleration occurs when a force acts on the mass. So for example someone weighing less would have more of an ability to bring themselves into the air to preform a trick rather than someone who weighs more. Newton's third law describes why the skater can jump or glide on the ice depending on the force they have produced. In my presentation I included pictures of how the process of spinning on the ice works. As the skater gets ready to preform a spin, she reaches her arms out for balance and lifts up one leg. The reason for extending her arms is because it will cause her to spin slower due to the pass she is putting outwards. However when the skater pulls in her legs and arm closer to her body she will begin to spin faster creating a constant momentum. Not only did doing this project inform me on the how physics is involved in figure skating but it also helped me become a better skater. Knowing how and why the tricks worked a certain way and how force can be a huge impact has really helped me preform better and know how to fix problems that were occurring before! Hope you all enjoyed reading this.

Rollercoasters and Physics

Basketball & Physics

A basketball player can jump as much as 4 feet in the air, and the higher he jumps the greater the hang time; the greater the time he will appear suspended in mid-air during the high point of the jump. Normally, there is a horizontal and vertical component in the jump velocity at take-off. The magnitude of the vertical component of the velocity at take-off will determine the time the player spends airborne. The horizontal component of velocity remains constant throughout the jump since it is not affected by gravity.  In the poster I have graphs that show the hang time that a basketball player will have when they are trying to take a jump shot or grab a rebound. These facts helped me learn how to further advance my basketball skills on the court.

The Physics of a Frisbee

My project here is based on the physics of throwing a frisbee. This project went over some of the laws of physics that are involved in the flight action of a frisbee. I have included images of my own and one from the internet. The internet image is an important contribution to this project due to its demonstrational appeal. I have also included some background history of the item itself. According to its history, the name "frisbee" was derived from college students who would play with a disc-shaped object and yell this word. The routes of this game come from things such as playing with cookie and pie trays. The person responsible for developing the product we know today was Walter Frederick Morrison. Morrison was an inventor and entrepreneur. Thanks to him, we have one of the best toys in history.

physics of cars

My blog is to show how Not many people know about cars but there is a lot of physics in cars. A car's acceleration, the movement of the car and how the engine works has a lot to do with physics. A cars acceleration, the movement of the car and how the engine works has a lot to do with physics. Speed and how the vehicle performs. The cars velocity in meters per second, is determined intergrating the acceleration overtime. For example If a car is going down a hill The car will go a lot faster due to the force of the car rather than it on a flat surface. Smaller cars weigh less rather than big cars. An important effect when accelerating or braking is the effect of dynamic weight transfer. During acceleration the car leans back and when braking the car goes forward. Cars are something people use everyday and it's important to know how it works and how to use. I think this is very helpful now that I have a car I have learned a lot more.

Physics of Cheerleading

Cheerleading is an athletic activity that is chock full of physics principles. Whether cheerleaders are creating momentum, acceleration, rotation or demonstrating shear force, they always seem to have Newton and his laws surrounding their every move. Understanding the physics of cheerleading is beneficial for performance. This understanding can also provide you with the knowledge to prevent injury and awareness of your safety. In Cheerleading there are jumps, tumbling, and stunting too. It might seem extremely simple but theres way more work then one might think. Many concepts of physics come into play such as Gravity, Newton's Laws of Motion, Momentum, Kinetic and Potential energy, Force acceleration, and Free fall.

Physics of Ballet

Dancing is a difficult, disciplined, and beautiful form of art.  It requires strength and teaches correct body placement and gracefulness. This genre of dance allows one to express their emotions.  It consists of movements of the body with poses.  These poses demonstrate the balance of a part of the body.  The forces that act on a dancer are: gravity (downwards), support from floor (upwards), and friction from floor (sideways). Friction is the force that resists relative motion between two bodies in contact.  If dancer is motionless, then all forces acting on the body are zero.  When a dancer's force is pushing upward from the floor to the foot, it is acting on the same vertical line as the force of gravity pulling downwards and the force of friction pulling outwards.  The dancer's moment of inertia depends of the mass of the body and its distribution relative to the axis of rotation.  "Physics is ballet in disguise."

Physics Of A Frisbee

baseball physics

While researching the physics of baseball I learned that there is a lot of velocity/ momentum involved. Throwing a baseball takes a lot more than just throwing it. You need to think about air resistance and the amount of force you apply to it. When swinging a bat you also have to think of the amount of force you use. If you don't use enough force the ball might not travel far enough.

Physics on a Roller Coaster

My blog was about the physics formulas and dimensions used throughout a ride on a roller coaster. Part of the physics on a roller coaster is work and energy. The ride often begins as a chain and motor exerts a force on the train of cars to lift the train to the top of a hill. The main energies used back and fourth while being on a roller coaster is potential and kinetic. This helped relate to my topic because we learned about potential and kinetic energy in the beginning of the year, as well as the formulas. Physics formulas that are used on the roller coaster ride are the kinetic energy plus potential gets you the work. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation. Throughout this ride, kinetic and potential energy go through a back and fourth cycle. It was cool to learn that a roller coaster card contains a large quantity of potential energy which  is dependent upon the mass of the object and the height of the object.The train of coaster cars speeds up as they lose height, so original potential energy transforms into kinetic energy. As the ride on the roller coaster continues, the train of carts are continuously losing and gaining height. Each gain in height corresponds to the loss of speed as kinetic energy (due to speed) is transformed into potential energy. It's really cool.

Physics Of How Ball Is Bowled In Cricket.

Now that I have already explained to you guys about the physics behind the "cricket ball" I wanted to go more in detail into the cricket ball itself and how it's not the ball that most of you think it is.  This is related to physics because in my previous project I explained to you guys about the  "Magnus Effect".  However, the Magnus effect won't be as effective if it weren't for the shape, size and design of the ball.  As you can see its much harder and heavier than it seems.  That is why I consider it as "sport of the brave" because it's very easy to die to that ball if it were to hit any vital spots on our body.  Some professional players can actually master the Magnus effect to the point where they can abuse it to throw some of these deadly balls intentionally. Magnus effect can also be very powerful when there is a strong wind that is pushing the balls towards the person that is hitting the ball.  In the cricket scene, many people look at this as a negative, but some also look at it as a deadly skill that can help them achieve their goal to "win".

Physics of Ice Hockey

My poster is about the physics in ice hockey, in my poster is all the physics that work with hockey, theirs not a lot but there is some, so now I am going to explain how hockey works and how it's made. The object of the game is to get the puck into the opposing teams goal, where you have 5 players on the ice with their goalie, the forwards are in front for offense and defense. For offense there are three one called the left wing, another called the right wing, and then center. Their goal is to shoot on the opposing team. Defense on the other hand is just 2 players, right defense and left defense and their goal is to keep opposing players out of their zone and help out the forwards. The rink or the surface of the ice is 200 ft long and 85 ft wide usually in the NHL or any other rink around the world, but there are such things as smaller rinks or even bigger. The boards that are surrounding the rink are 8 ft tall, so no puck goes out and hits anyone or any hockey player goes flying into someone. The usual height for a hockey net is 4 ft and 6 ft wide; when a hockey player shoots at the net it can end up by going 100 mph which is dangerous for the goal tender, but that's why they have all of that padding.

Physics of Billiards

When you hit  a ball in Billiards everything matters. If you want to hit the ball perfectly you would need to find the "sweet spot" of the ball.When you hit the ball it is hard enough to hit the other ball into the hole.
The stick you use doesnt matter. What matters is how hard you hit it and where on the ball you hit it and the way you hit it. Many things matter on how you hit the ball. Collision also matter in billiards, you don't always need to power hit one ball. You can also hit in a ball with another ball. Depending on the way you hit the ball matters if it get into the hole or not. This entire process is elastic collision.

The Physics of Hot Air Balloons

     A hot air balloon is a large bag filled with hot air or gas that allows it to rise. Although hot air or gas helps the balloon rise, physics is behind it all. The physics that deals with a hot air balloon is called buoyancy. Buoyancy allows certain things the ability to float in water, air, or any other fluid. The way buoyancy works with a hot air balloon is the upward buoyancy force is equal to the mass of the cooler surrounding air that is displaced by the hot air balloon. Therefore since the air inside the envelope is less dense than the surrounding air, which causes buoyant force because the cooler surrounding air is greater than the heated air. Although floating a hot air balloon is not so simple. When flying a hot air balloon the atmosphere will change depending on how far you are from earth, which causes a change in pressure. Along with that gravity has a part in flying a hot air balloon too. Gravity will pull the air molecules down which creates more molecules in the air. But buoyant force keeps the balloon lifted by using the air molecules to keep the weight equal.

In reflecting on my research on ice hockey, I think it was really cool to learn that velocity is associated with a slap shot move.
