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".

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
Here are my top 5 tips to performing the best possible:
5) TARGET THE UNITS IN WHICH YOU PERFORMED POORLY ON TESTS. If you aced that rotational motion test or blew through the early dynamics tests, odds are you don't need to prioritize your study sessions around them. Focus on the tough stuff that you know you could use the extra points for. Getting those extra points that few students usually get will boost a 3 to a 4 and a 4 to a 5
4) DO EVERY PRACTICE QUESTION POSSIBLE. Each released AP
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
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
Friction is a pain in the butt when we look at kinematics problems. It is the main non-conservative force, meaning that it changes the total energy in the system. When fining net force or total energy, friction is always a tricky negative sitting in the dark to take points away from innocent physics students. The statement "if friction is negligible" yields an instantaneous sigh of relief, since our job just became that much easier. So why should the universe have friction at all? Well, with no
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
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.
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
I = integra(mr^2)
and so on...
1)KINEMATICS EQUATIONS. They are everywhere. EVERYWHERE. Those who know when to appropriately
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
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
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
When I was in the 8th grade, I always dreamt of taking physics in high school. Unfortunately, my motives at the time were somewhat naive; I used to think that a physics background would allow me to never miss-throw a baseball again. With a handy protractor, I believed that I could throw a baseball any distance I desired with little effort as long as I threw it at the perfect angle. Physics has since crushed this dream: the ball will only have a finite amount of time in the air, based on the comp
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
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)
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
There are two categories of snowboarding: Freestyle and Freeride.
I fit more into the freestyle category, but i wasn't always. Two years ago, i started snowboarding recreationally. Seeing all of the kids doing impressive tricks on their boards, I wanted to try my hand at the sport. However, I found rotation to be very difficult for me, and i could see why: with my big feet, I could only rent a large board. In any case, angular momentum is conserved, but with a really large moment of inertia
The other form of snowboarding is called Freeride. It focuses on going fast and carving your own trails out of a mountain. Although I upgraded my board to increase my rotational velocity, I sacrificed my ability to carve at speed. The edges of a snowboard are metal, and allow the snowboarder to apply a resistive force using their legs and friction to slow down their body. In this case, a longer snowboard would provide for a more stable ride because the force is applied over a larger area. This r
Super Mario Bros defies many different forms of physics. Assuming his round belly carries some weight, I would be nice to give him a weight around 200 pounds. Since he can jump over 5 times his body weight, his legs would need to lift at least a tonne to come close to the approximate strength to perform such a feat. In addition, kicking the koopa shells would create an equal and opposite force back onto his feet. He would not be that agile if he were wearing steel-toed boots, so it should hurt a
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
It has come to my memory that equation dumps are a staple to our physics careers. So, as taken from an old sheet from last year, I figured I might as well start memorizing early! The better recall now the better recall later! (Please excuse the really poor table making)

The other day, my dad and I were moving a couch for my uncle. For arbitration, let's say the couch weighs 100 N. Because my dad stands 6 cm (.06 m) inches taller than me, it can be assumed that the couch will be offset as well. If the couch is about 4 meters, the angle is about arcsin(.06/4) = .015 degrees from the normal or 89.985 degrees from the x axis. Therefore, if each us lifted an equal amount, we would lift the couch with 50 N each. However, we would be generating a torque equal to the F
I know all of us have a habit of just getting by in physics, especially on Wednesdays I mean, I'm not going to lie and say I dedicate the full time during these independent units, and sometimes it is honestly difficult to grasp the concept using strictly the materials given. One website that Mr. Fullerton gave us towards the beginning of the year that really helps me get quick and concise information. HyperPhysics allows you to search for specific topic and gives you the facts and diagrams you
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
I remember the first time we saw the integral was in physics C. It was extremely intimidating because we struggled to make sense of the differential equations, let alone evaluating the integral itself. The very first problem we got, we were spoon-fed the fact that the integral of (du/u) was equal to ln(u)+C, and that made absolutely no sense to me. Now, into the third quarter and after attending the calculus school of hard knocks both 2nd and 3rd period every day, i think its is safe to say that
