  1. Hello, my name is Max and I'm a senior in high school. Since everyone else is talking about the sports they play...I will too. My mother often asks me to stop playing tennis because it is such a physical sport, but I rarely listen to her so I continue to play at a varsity level. I can't have any pets except a boring fish because my dad is allergic to the fur on cats and dogs. At the moment I work at a restaurant called Hose 22 and I usually prepare food. I'm taking physics because it was recommended to me by my counselor. But I am excited to start physics because it looks like its goi

  3. Thrilled to help, and welcome to the APlusPhtsics Community! The short version... The College Board says you need to know how to derive them. Very rarely have they asked students to do so, but it has happened... This guide sheet may help with studying: http://aplusphysics.com/courses/ap-c/tutorials/APC-Dynamics.pdf Good luck!

  9. Money should not be spent to furthur study Particle Colliders. The united states economy is terrible and so money should not be wasted on information that we can live about. The information obviously has important benfits. We could feed children in ghana instead of spending money on science that is not needed. The money could go towards helping developing countries to provide water and food and items essential to live. We would unfortunately not have MRI's but kids in foreign countries are more important. The research for particles colliders is just too expensive to be worth it.

  10. BREAKING NEWS recently three students, Mike Belmont, Zach Haight, and Jake Barnes have found acceleration by gravity ina series of steps including using meter sticks to determine the height from the ball too the ground from the cieling of a classroom. by doing so they measured the time it took for the ball to hit the ground and also measured in metersthe height of the ball off the ground. they determined the acceleration by using a formula to determine distance and used conversions to find the acceleration of 8.98 meters per seconds squared. we can use this to determine acceleration on earth

  11. Article: Breaking News! West Irondequoit physics students have calculated the acceleration due to gravity! In a physics lab students participated in, they used only a stopwatch to find the acceleration due to gravity. They dropped a ball from the ceiling of their classroom and used only the initial velocity, height of ceilings and the time it took for the ball to drop from the ceiling to find the acceleration due to gravity with an equation. When calculating this, they had only 3.98% error from the actual 9.81 m/s2. They got 10.2 m/s2 for the acceleration due to gravity. The stude

I plan on joining the air force and becoming either a pilot or any other cool job I find out about. I am probably the only person taking this class that thoroughly enjoys science. I'm that person who sits at home and watches through the wormhole with Morgan freeman and thinks about the world and how we've come to understand it. I am also taking so bio (why? Because I can...) and I think Mr. Fullerton is super hilarious (true, but hoping he'll read this and I

I grew up in east Irondequoit until my mother remarried in 2008 and I moved to west Irondequoit. My interests outside of school are dancing. I have been dancing for fourteen years and will continue to hopefully become a dance teacher. I also have two jobs that I manage during the school year, which are being a dance assistant teacher and working at Auntie Anne's. In addition, I am taking regents physics and Mr. Fullerton is my teacher. Junior year I didn't think abou

  25. Hello, I got to this question and was not sure how to go about it. I sorta had an idea but that was for the line charge of a fixed length, so do I just ignore the lengths and assume that E= lamda/(4 pi e0) and then use V=int(E*dl)?

  26. Hi, My textbook asks the question: The phase of an Electromagnetic wave at a point P at some instant is 5pi. Which of the following statements about the field vector is true? A)Both the electric and the magnetic field vectors are 0 B)The electric field is 0 and the magnetic field has its maximum magnitude C)The electric field has its maximum magnitude and the magnetic field is 0 D)Both the electric and magnetic field vectors have their max magnitudes. My question for this question is, is the textbook talking about phase difference? If so, how can the magnetic field and the electric fiel

  27. Hi Mr. Fullerton, Thank you so much for your swift response. However, I am not sure I understand what you mean in: To choose between A or D, look at the function you're using to model the waves and its value at time t=0. With a phase change of 5Pi, you'll have the opposite situation you would have at time t=0. So for a basic cosine function modeled so that the E field has a maximum value at time t=0, at the instant in time where the phase is 5Pi, it would be at a minimum (0) value, so the answer would be A. If you are modeling the wave so that the minimum value is exhibited at time t=0

  28. Question: Three charges are placed at the corners of an equilateral triangle with sides of length 2.0 m. The three charges at the corners of the triangle at +4.0 X 10^-6 C, +2.0 X 10^-6 C, and -4.0 10^-6 C. Determine the electric potential at the midpoint of each side of the triangle. What I have done so far: So we know that the formula for electric potential is V=kq/r. So we can just use one of the charges to find the voltage. However, the answer differs depending on which of the 2 charges(which vertices you pick) for each charge. Thank you for taking the time to answer my ques

  29. If you asked me that question as a fourth grader or even seventh grader I would have said a scientist. I was asking for microscopes for Christmas as age nine, and anatomy books at age 11. And I will admit to playing a few video games. Shockingly, I want to be an English major now. However, physics is the best subject known to man. Especially if you are blessed to be in Mr. Fullerton's class. Best teacher ever.

I wish to pursue a career in economics or photography. I am currently taking regents physics. I am taking it because I wanted to take another year of science because it looks good for college. I decided on physics because I did not want to take biology or chemistry again. I think I will really love Physics this year because Mr. Fullerton seems really nice and fun.

  37. Hey way to go on becoming an Eagle Scout. That looks so good on college applications. I think we all will learn some interesting this year. I bet we can connect everything that we think of. Like you can connect to soccer as well as your adventures with your troop. And I can connect to hockey. It will be a challenge but we can handle.

  38. NO GO!!!!! Your fuel use is ridiculously high and inefficient. You will waste a ton of money on parts that will just crash back down on Kerbin because you don't have parachutes on them. And you will kill your Kerbal because there is no parachute on his cockpit. Rethink this one before launching.

  39. Docking can be one of the more difficult maneuvers to learn when it comes to judging when the correct time to burn engines to rendezvous with target, but if you can successful it can be an efficient way of landing and knowing you still have fuel left in your drive stage to return you home. I would similarly recommend training yourself by attempting to build a small (key word there. Small) space station.

  40. For your first attempt at putting a satellite into orbit this is actually quite impressive. As for matters of efficiency, before I could see the pics I seen in your parts log that you were bringing a lot of fuel and you would no question be able to achieve your goal even if you halved your final stage. You did however do a fair job with what you used. Nice use of fuel lines to feed the central tank. You may find in future that if using wings that you don't need a gimble functioning engine or vice versa as either one on their own would allow you to turn easily saving weight, mass and re

  44. The posters around the halls and in classrooms have gained some traction and have garnered perhaps an increased awareness of the potential for STEM careers- but is it too late? I sometimes wonder if we haven't done enough to build the curiosity and "excitement" for STEM in the levels for where it matters most - in the elementary, middle and junior high levels. Some of the best experiences within science programs have been removed (Science "fairs" or long term projects that allow students to build models, test designs and collaborate with peers - outside of school have been replaced).

  45. This just in!!! A young physicist of only 17 years old has just calculated the acceleration due to gravity on planet earth. In Irondequoit high school in Rochester New York a group of mere students proved the age old physics fact. Blind faith couldn’t satiate their thirst for knowledge. Armed with a ball, tape measurer, and stop watch these physics fighters set out with a mission: find gravity’s acceleration. Excuse me, I’m receiving their procedure now……It looks as if they had one person start with the ball at a fixed point and then the same person let go of the ball and measured the time

  47. If you weren't a super duper physics student, it would seem so! However, Forces cause accelerations on an object. and if an object is not accelerating in any direction, two things can be happening to the object. It can either be motionless OR in constant motion; talk to yourself about the definition of constant velocity, thats how I wrapped my brain around that one. Velocity only changes with acceleration (forces), so a constant velocity means no forces or forces that cancel each other out. I hope this helps!

  48. And sorry to keep adding to this... but upon further investigation - you might want to be in Pascals (does that sound farmilar lol?). That is in N/m^2 so you will need to figure out how many m^2 you have from cm^2. There are 100 cm in a m, so 10,000 cm^2 in a m^2 (100x100=10000). Divide your area given by 10,000 to find how many m^2 you have instead and then plug that number into P=F/A as the A instead of in cm^2 and you will have your answer in pascals.

  49. I'm hoping this is the right place to post for Physics C Problems. I thought I heard that people were confused by the billiards web assign so I thought I'd weigh in. To me it seems like the velocities of the cue ball and the 8-ball have been switched on the webassign, but maybe I'm crazy. Also, I only know from experience that perfectly spherical billiard balls that collide perfectly tangentially ricochet off each other at complimentary angles, but the mathematical explanation in the answer packet leaves a bit to be explained for me. Any clarification would be much appreciated!
