  3. This year has been amazing for me. I never thought that I would be able to do things such as a drag force derivation, or transient analysis of circuits, but I proved myself wrong. Through hard work and a lot of time, I matured through this year into an independent student who has faith in his own intellectual abilities which can all be attributed to the workload of AP Physics C. I learned that it isn't bad to ask questions as long as you have tried your hardest and thought about it until you cannot anymore. I have also learned to attack problems with other people, and combine knowledge in order to come to a solution which is extremely satisfying in the end. I now feel much more prepared for college and the challenges that I will face there. I have learned that it is OK to fail as long as you have put your best effort forward, because it only means you have room for improvement. Physics C has brought me many emotions both happy and sad, and has pushed my thinking to places It has never been before. I will undoubtedly miss Physics C, but will look back on it as a stepping stone in my path towards higher learning and eventually a career.
  4. Well this is gonna be a hard one. In Kerbal Space Program, Physics is the name of the game. It is the most true to life space exploration simulation that is readily available to the public, but it still insanely fun to play. You control a whole space program, and decide everything that it does. You control the mission plans, creation of spacecraft, and the actual flight and maneuvers. The Physics engine in this game models real life down to the smallest details: drag, propulsion, center of mass, center of lift, this game has everything. What would be harder to write about would be what isn't realistic about this game. One of the aspects I would like to focus on however are orbits. One of the first milestones in the game is getting a spacecraft into a stable orbit around Kerbin. You have to plan your fuel consumption and staging so that you have enough fuel to adjust your orbit into a circle once you reach the correct height. This can be done by scheduled "burns" or extended periods of time where the thrusters are fully firing towards a certain direction to cause a desired orbit path. Once you finally get into orbit however, nothing is more satisfying considering you used the laws of Physics to accomplish it.
  5. In Call of Duty Black Ops 3, you are able to run on walls for a short period of time. Though this is unrealistic, humans are actually able to run vertically up walls for a quite impressive distance. This is due to the force of friction. When you make contact with the wall with your hands and feet, you push them downwards in order to imbalance the forces. If the force of friction is greater than the force of gravity, you will be propelled upward when you run up the wall. This means that the force upwards is greater than the force of gravity downwards, causing a net force upwards accelerating you up the wall. However, you cannot run far up a wall from a stationary position. You must first get a running start in order to build up speed, energy and momentum which can then be used to get even higher.
  6. In Nightfire there is a rocket launcher that fires homing missiles. These missiles follow their target until they hit a surface and explode. How they do this is based off the principle that warm bodies emit infrared light, therefore if a rocket were to follow infrared emissions it would most likely be following a body. Homing missiles are so effective that 90% of all US air force losses can be attributed to them. In order to change directions mid flight, it adjusts the direction of its rear thruster according to the direction the infrared light was received. This is done so quickly that the missile has smooth turns and adjusts its flight path at almost the same time its target does. In Nightfire, this creates a weapon that is pretty much unavoidable unless you disappear into a building or behind a safe wall.
  7. Chaos theory is quite interesting! Nice blog
  8. Crazy to think that i might be made of strings..
  9. Solid job! I can see your hard work paying off for sure
  10. Nice! I love doing the wave! Haha
  11. In one of my favorite Gamecube games of all time, James Bond 007: Nightfire, you are able to choose from a multitude of characters to play as and complete missions with. One of these characters is names Oddjob, who is extremely short and wears a trademark black bowler hat. This hat will be the focus of my blog. In the game, you are able to take off your hat and throw it at enemies much like a Frisbee, but this isn't playing a game, it's to slice peoples heads off. The 2 reasons the hat is able to fly are the Bernoulli principle and gyroscopic inertia. In simplest terms, the Bernoulli principle is the idea that air flowing below a wing or in this case Oddjob's hat's brim, has a higher pressure than the air flowing above, causing lift. The hat remains stable and spinning because of gyroscopic inertia, which is the principle that a body that is set spinning has a tendency to keep spinning in its original orientation. Both of these principles combined cause a stable, spinning, flying blade which gives you an edge up on your enemies.
  12. Super Mario Strikers is a cartoon soccer game some will remember playing on their gamecube's or wii's which was extremely satisfying because of the unrealistic goals and crazy plays. However, there is one aspect of the game that is realistic and has physics behind it: The bicycle kick. The bicycle kick is an extremely hard and athletically demanding feat, but if performed correctly can stun your opponent and create insane velocity on a shot. A ball must be lobbed in the air to the person shooting, and the person shooting must have their back to the goal. They then swing their foot over their head towards the goal and make contact with the ball, shooting it towards the net. The reason for the immense power of the bicycle kick can be explained by circular motion. As the person swings their body and legs over their head, their foot if moving in a circle. Once the ball is struck, it moves in a line tangent to the circular path that the foot is on. This is the raeson why the ball must be struck when the foot is at its highest point or close to it. This causes a flight pattern that starts parallel to the goal and eventual dips down and sometimes even over the goalkeeper.
  13. The Nuclear bomb is believe it or not one of the main weapons in Fallout 4, but ironically is also the cause of the game. The Physics behind Nuclear bombs is extremely complicated, but in this blog I will try to explain it as best as I can. The immense energy behind a nuclear explosion can be attributed to nuclear fission, which is the splitting of atoms. In a nukes case, it is most likely Uranium - 235. Two masses of highly pure Uranium 235 are positioned perfectly so that when they collide they start a chain reaction unleashing massive amount of energy in the form of an explosion. The masses collide extremely fast in order to keep the time of fission short, so that the explosion is as powerful as possible. This was the type of nuke dropped on Hiroshima in 1945 which killed so many people and caused destruction never before seen by man. The initial explosion wasn't the only terrible thing to happen however, because after the explosion massive amounts of radiation remained which made the area and its surroundings uninhabitable. Fallout 4 does a great job of recreating a barren wasteland which the player can easily tell has been ravaged by a nuclear bomb. <--------- Nuclear Fission of Uranium-235
  14. In Roller Coaster Tycoon, your main goal is to build an amusement park with the coolest rides to get the most profit possible. Your main weapon in your arsenal is the rollercoaster of course, which relies on a basic principle of physics to work. The carts are pulled up to the top of a hill by a chain system similar to that of a bike, and are then released at the top and fly down the hill at immense speeds. This is because of the law of conservation of energy. As the carts are pulled higher, their gravitational potential energy (pe=mgh) is rising. As they fly down the hill, the potential energy is converted to kinetic (ke=1/2mv^2). Aside from the physics of it all, rollercoasters are just another great application of physics in the everyday world.
  15. Fallout 4 is a survival open world game. In the game there is a weapon called the "Big Boy". This is a handheld mini nuke launcher. While this is impractical in real life, there is physics behind how the game makes it work. Since no heat or pressure can be applied to the nuke without it blowing up, the launcher uses springs and elastics to store energy and launch the nuke smoothly. This can be seen my the equation of Spring PE= 1/2kx^2, with k being the spring constant and x being the displacement. All of this energy gets converted to kinetic energy in the nuke when it flies. This also obeys projectile motion which can be read in my last blog, where gravity pulls the nuke down and the velocity is retarded by wind. The physics of why the nuke is so powerful is a whole other blog, which I will cover soon.
