"Tag"

We just recently finished a game in calculus. We called the game “tag” but it really was a game of assassin where we could get people out by shooting them with water guns. We had to be very stealthy because no one was supposed to know about it. To keep up with the stealthy behavior, shooting long range squirt guns would have been really effective to get people out without them realizing what hit them. In the beginning of the year we conducted a lab with q-tips and plastic straws. That lab d

Goals for the rest of the year

We are now entering our last quarter as seniors in high school. I want to rebound from an uncharacteristically bad academic performance in the third quarter and finish strong in the last quarter. This is now a prime time to start reviewing for the AP test that is looming in the very near future. I for one am quite a bit nervous but I have a plan to follow that will get me prepared for the day of the test: 1. do 1 blog post a week 2. Read text book a little bit each night 3. do webassigns a

physics of a mowhawk!

The varsity cross country team decided to get mowhawks to get pumped up for thier sectional race this past saturday. As a member of the cross country team i got one as well. Most of our runners had long enough hair to spike it and create very large and excentuated mowhawks. I didn't have enough hair to do that so i got the sides of my hair shaved off and my mowhawk looks like a drag strip right down the middle of my head. This type of mowhawk has some very unique properties. As a runner, i

Physics of karate chopping!

Ever since i saw my first Jackie chan movie (which i cannot remember off the top of my head), i have always been curious how a man, not especially strong and bulky with the muscles most football players possess, can break a cinder block in half with his bare hands. I previously thought that the cinder block would be too strong for even the most muscular man to even crack it let alone break it. In this video, the person had two thick bricks stacked on top of each other and he broke bot

The Cross Product

At the beginning of the school year, we learned the two forms of vector multiplication: the dot product and the cross product. The more intricate of the two, the cross product, comes into play in many equations to provide very useful information. For example, in magnetism, F=I(BXL). This means the magnetic force is a vector cross product of the vector of the magnetic field crossed with the length of the object multiplied by the current flowing through that object. The resulting force will ha

Relativity and String Theory!

Yesterday in class we learned about Einstien’s theory of relativity and time travel. Our physics teacher explained to us how traveling in space or being on another planet can alter the amount of time you feel and your body experiences. If someone is in Space for 70 earth years, their body doesn’t age those 70 earth years if they are far enough away from the Earth’s atomsphere. We also learned about how the speed of light is the fastest speed that can be achieved in the universe: 2.998 x 108 m

Spitballin

So when my family goes out to restaurants, my mom and i take the straws they give us, rip off the top part of the paper and shoot them at each other. We also make spitballs and fire them at each other at will before we receive our food. This relates to a lab we conducted in our Physics C class. We blew projectiles from straws and then blew those same projectiles through straws that are connected to other straws. Those projectiles traveled faster and farther. Velocity is calculated by dividi

Opposites Attract ;)

In the dating world, people with opposite personality types seem to be attracted to each other. In the world of electrostatics and magnetism, opposite charges attract each other and opposite magnetic poles attract each other too. Particles with a positive charge, such as a positive test charge, are attracted to particles with a negative charge, such as a negative test charge. The particle with the greater magnitude of charge will attract the other with a greater force. For example, if a part

Taking the AP Physics C test

On may 13th 2013 I sat down in my high school in the afternoon for my AP Physcis C exam. The first test I had to take was the mechanics exam: 45 minutes for the multiple choice and 45 minutes for the free response questions. The 35 question multiple choice part of the exam wasn't all that difficult but a bunch of problems took a long time to figure out. I didn't finish that part of the exam so I had to guess on the last 4 questions. The beginning of the free response section began with a air

Complexoty of Rocket flight

Rocket flight is much more difficult and requires much more calculation than it may seem to those not involved in NASA. The more fuel a rocket may have and the more powerful the engine a rocket may have doesn’t always mean it will travel the fastest or the farthest. The heavier the fuel tank, the more the rocket is affected by the pull of the planet’s gravity. Also, the more massive the rocket is, the more it is affected by the air resistance of the planet’s atmosphere. Many calculations go

The problem with u (mew)

In both physics and chemistry, u, stands for a lot of things. u is the coefficient of friction, with subscripts indicating kinetic or static friction. It is the permeability of free space. It represents a magnetic moment. It indicates a micro unit (10^-6). It represents linear density. In chemistry, it represents velocity. u is also used to represent values in music, pharmaceutical sciences, computer science, software design, meat science and linguistics. Understanding each and every rep

Deep passes in the AFC Championship game

During the AFC football game yesterday night, the wind was blowing really strong from one end of the field to the other. That can be a good and a bad thing for the offenses on each team. The offense driving into the wind will have their quarterback's passes subjected to the wind and his passes won't travel as far. But for the quarterback and his offense traveling the other way, his passes will be thrown with the wind, thus making his passes travel farther with the wind carrying them to some d

Circulatory system

Our bodies conduct physics every second of everyday. Our bodies pump blood. Initially, one may think that the mere action of pumping blood has no correlation with physics at all. On the contrary, the blood in our bodies must be pumped through muscle contraction and applied force as well as pressure. Last year in physics B, we learned quite a bit about fluid mechanics and the relationship between force, pressure and area of the tube the fluids travel through. As our heart initially pumps blo

The class so far

So far for me, Physics C has been a challenge. There is a lot of information to learn and a lot of abstract ideas that I have difficulty wrapping my head around. Despite the many difficulties, that i know most of my fellow classmates are experiencing simultaneously, i find this class extremely rewarding. I have learned so much not only about physics but how to properly study and learn complex information accurately and effectively. I also find the content very interesting. So many things ha

Centrifuges!

I aspire to be involved in the medical field once i finish my schooling and one of the tools i hope to use is a centrifuge. Centrifuges are tools where test tubes are inserted into spaces around the outside of the tool. It then spins in a circle and the more it spins, the contents in the beakers are separated into their components. The contents in these beakers mostly consist of blood samples and organelles that need to be separated to be analyzed. Centrifuges use the centripital force to se

In preparation for the AP

In preparation for the AP Physcis-C exam, I did a number of things that helped me to properly review the year's material. 1.) I looked over each test and studied the questions that gave me the most trouble. 2.) I re-read the parts of the text book that described specific properties regarding certain topics during the year such as the properties specific to conducting and non-conducting shells. Also, I looked up and reviewed kirchoff's loop rules and the properties that go along with the
