## Why don't jet packs exist?

With all of the renowned technological advances made within the last few decades, many people have sought to create a jet pack for commercialized use. However, although prototypes have been seen, it has been met with relative failure. This is due to the materials required to reduce the weight. Gravity creates an acceleration downward, while the thrust of the jet pack would attempt to create a net force upwards large enough to counteract this force. Unfortunatley, the heavy mass of the person pre

## Top Three Things you want to memorize for a phyiscs test!

3)MOMENTS OF INERTIA. These simple equations are a pain in the butt and stop you short of a point or two on a question if you don't know them. [ATTACH=CONFIG]584[/ATTACH] 2)DERIVATIVE RELATIONSHIPS. Enough said. These relationships come in handy on all graphing questions and can pick up points on the questions that are specific to derivatives. a = dv/dt v=dx/dt I = integra(mr^2) and so on... 1)KINEMATICS EQUATIONS. They are everywhere. EVERYWHERE. Those who know when to appropriately

## Tips for Students Entering Next Year

1. Keep up with the blog posts!!! DO NOT PROCRASTINATE LIKE I DID, IT IS NOT VERY FUN TO DO. The blog posts are not a large amount of work, and they are a massive grade booster for the class. 2. Read the Textbook!!! The few times I took a look at Tipler, I gained valuable, relevant information on the current topic in class. It is by far the most useful tool Mr. Fullerton will give you when you miss a day. When I was out sick for 3 days, the textbook taught me the entirety of Gauss's law, whic

## Theoretical Physics VS Experimental Physics!!!!

Theoretical physicists develop "mathematical models that both agree with existing experiments and successfully predict future results", while experimentalists devise and perform experiments to test theoretical predictions and explore new phenomena. Although theory and experiment are developed separately, they are strongly dependent upon each other. Progress in physics frequently comes about when experimentalists make a discovery that existing theories cannot explain, or when new theories genera

## The Wonderful World of Quanta

Hello, physics students! Lately I have taken an interest in quantum mechanics, in an attempt to improve my grade, but mostly because it is a truely stupefying. It still amazes me that briliant minds like Boltzman, Heisenberg, Euler, among countless others could possibly explain entities that they could "easily" touch but never physically see. Today, I want to give a brief background on the foundation of Quantum Physics: The uncertainty principle. It is this equation that gave Werner Heisenberg c

## The Perfect Fifth

For those of you who don't have any musical knowledge, the perfect fifth is the best sounding sound interval to the common ear. It is the key ingredient in structuring chords based around the root. With a 3:2 ratio, it creates a nice and pleasing sound to the ear. The most common example of a perfect fifth is a C to a G. Kepler himself, founder of the planetary laws, researched the beat frequencies of the error bound for an imperfect fifth tuning. Just a slight slip-up in tuning can create an un

## The Laser Lab: What I did this Summer

This summer, I worked under the tutelage of Wade Bittle and Dr Steven Craxton at the university of Rochester. I worked on a project called Dewpoint calculation using flow transducers. The preliminary time at the internship was spent gaining a basic knowledge of integration, and learning about the omega lasers functions and work schedule. Although we never got to see a shot (a single blast would vaporize our corneas) we had a good understanding of the process going on. When fusion occurs, there i

## The AP Exams

As late as it might be, I'd just like to take a bit to reflect on the ap exams. We worked our butts off to try and achieve the highest possible. I bough review books, took old practice exams, and worked out all part 2 problems from recent years. Needless to say, i was completely prepared by may to take that test. And yet, I still walked into that exam and came out a little uneasy. The mechanics exam was relatively straightfo​rward, with just one part two that gave me grief. However, mr. Fullerto

## Steps to Understanding the Direction of dI/dt

1. Sit down 2. Look at the paper 3. Think for 30 minutes, trying to understand it 4. Try not to cry 5. Cry alot But if you actually want help... http://en.wikipedia.org/wiki/Inductance

## Standard Deviation

While we use percent error to dictate how far we off in class, there are far more efficient ways of defining the error of the set. Standard deviation, for example, given a value, will give rise to numbers that fall within one S.D., two S.D. and so on. "One can find the standard deviation of an entire population in cases (such as standardized testing) where every member of a population is sampled. In cases where that cannot be done, the standard deviation σ is estimated by examining a random s

## Sound

In Washington DC, there is a building with very interesting sound diffraction patterns and design. Sound travels in waves in straight lines until they reflect , get absorbed by, or refract off of a medium. This room was designed with bipartisanism in mind. The desks were set up so that sound would interfere with itself so that opposite members of congress could not hear what they were saying. However, the architect overlooked basic resonance, since the arches were placed just right so that membe

## Semester Reflection

Wow has this semester flown by! We breezed through the mechanics course, almost with time to spare, it seems! I believe we have a powerful class of students who like to compete for grades, and in the process push themselves and others around them. As I expected in the beginning, I love the independent units and actually found success on the tests that we took following them. I loved the refresher courses on Mechanics as well as the new material that we have learned more toward the second half. T

## RIT Physics Program

I am excited to start my college physics programs next year. Since I have collected so many credits (Thank you Mr. Fullerton and Mr. Powlin!), I will not need to take the first two courses of Physics at RIT. Therefore, I will be taking a physics exploration class the first year. This will allow me to look at all different kinds of physics, even units we never covered in high school. I am very enthusiastic about the quantum level of physics, and I enjoyed the modern unit in B, so I think i will b

## Relativistic Baseball

Just in case any of you were wondering, this is what would happen to a baseball if a pitcher could approach the speed of light! http://what-if.xkcd.com/1/ [ATTACH=CONFIG]479[/ATTACH]

## Quarter 4 and The End of Senior Year

Guys, we have just finished the hardest classes in the school. I think I speak for all of us that senior year was quite stressful, but a great relief as well. We gained knowledge that far surpassed any other year. With Physics and Calculus placed 2nd and 3rd period conveniently, I think we all became morning people! To be honest, I never expected leaving to really effect me the way that it is currently. I am truly going to miss all of my high school friends. We have all toughed out our years, pu

## Quarter 3

This quarter was a roller coaster. With my grade in the tank at the beginning after one bad test, I have been climbing very slowly ever since. I enjoy the fact that we are actually having more independent units this quarter. The very first one was very effective, and although we took for granted the class time in these units, our grades showed significant prowess from these tests. I am both excited to buckle down and commence prep for the exams soon, but I am afraid of this new induction unit! I

## Quarter 1: A Recap

Okay, here's my thoughts on physics C so far: Although the tests are challenging, we are more than prepared for them, and maintaining the difficulty will make the AP test at the end of the year That much more accessible. I enjoy the fact that we expand in every direction the fundamentals we developed in physics B. In this way, the concepts are not too challenging , and the calculus application fits into past knowledge quite nicely. In fact, the calculus problems we are given are actually easi

## Physics Problem

I have a phun physics problem for you guys to try out! A 5 kilogram ball is being lifted up. It's potential energy is increasing at a rate of 3.5 Joules per second. What is it's velocity at t = 15 seconds? (HINT: You might find implicit differentiation helpful... Sorry non-BC kids)

For those of you who don't know, there are many cool physics channels on YouTube for those of you who want to explore subjects outside class curriculum​. My favorite is Minutephys​ics, which covers small snippets of informatio​n at a time. ﻿ ﻿

## Physics of Volleyball

Volleyball is an interesting sport. It's very fun to play with friends with no serious competition, but once it's played for real, it is a difficult sport to master. You'd think it would be physically impossible to hit a sphere with two cylinders. Our studies of momentum have indicated that the collision would bounce off at irregular angles. Since it is easy to make passing unpredictable, I do my best to flatten my wrists by rotating them. Creating a flat platform, I am able to successfully pass

## Physics of Guitar playing

I am constantly stunned when I listen to a new guitarist make sweet music, and yet I am also always amazed by the music that bands such as Led Zeppelin made previously. So how do all of these bands make sound that is pleasing to our ears? Well, physics takes its part in melody making! Although we didn't cover it this year, sound waves were one of my favorite unit of physics (probably because I got to bring my guitar in last year to demonstrate harmonics). Guitars can be tuned so that there is a

## Physics jokes to ease the pain of this upcoming midterm!

In the early 1900's, name foreigners came to america, and they had bad english skills, espeicaly with tense and past tense. So, one day, a german who just entered the country lost track of the time, as he needed to catch a train , so he asked a physicists "What is time". The physics replied "You will have to ask a philosopher that question, I'm only a scientist". Your mother is so fat, men are actually attrracted to her, according to General Relativity Many people espouse the works of Rene

## Physics and Speeding

As I am driving my car "55" miles per hour on the highway, I throw a baseball "55" miles per hour in the opposite direction. Amazingly, the creepy man standing on the side of the highway watched the ball fall straight down. Since the velocities are equal and mass doesn't change, there is no net momentum, and therefore no net force in the x direction so the ball will only be affected by gravity acting straight down. Likewise, if I threw the ball 45 mph, the creepy guy would actually see it travel

## net F = MA

As simple as this equation seems, it is a staple in mechanics. It has many different applications. These uses vary from setting up equations to find tensions to simply finding the net force of an object in motion. It is 0 when an object is in constant velocity or when the system is in static equilibrium. Then, when we convert the quantities into rotational motion, and we get net Torque = I(alpha). For an equation that seems very simple and easy to apply, there exist tricky problems that require

## My First Blog

Hello world! It is a pleasure to make your aquaintence. I have taken a liking to physics since I took AP physics B. Assuming that we are all nerds, I would guess that this statement would be common (we're all making a blog post on a physics site, arent we?) I am strong in logical reasoning and arithmetic, and would like to improve my test-taking skills throughout the course. I am taking AP-C to further my experience in the field to prepare for college and future work. I can't wait to use calc
