  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.

  11. When visible light, X rays, gamma rays, or other forms of electromagnetic radiation are shined on certain kinds of matter, electrons are ejected. That phenomenon is known as the photoelectric effect. The photoelectric effect was discovered by German physicist Heinrich Hertz(1857–1894) in 1887. You can imagine the effect as follows: Suppose that a metal plate is attached by two wires to a galvanometer. (A galvanometer is an instrument for measuring the flow of electric current.) If light of the correct color is shined on the metal plate, the galvanometer may register a current. That reading i

  12. Introduction: We decided to see if cars travelling North down Cooper Road outside of Irondequoit High School were speeding. We set up a timing station at twenty meters from the start to measure the speed of passing cars. Procedure: We chose a starting point on a line on the road, so timers could better see when cars started the measurable distance. When a car passed the starting point, timers at the station began their stopwatch. When the car passed the timer, they stopped their watch. Timers recorded the time it took for the car to travel the distance. Calculation: Conclusion: The av

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

When i'm not in school i'm working, and when i'm not working i'm sleeping. When I'm not sleeping I'm usually buying something online or in person that I really don't need! I am looking forward to my senior year! I took physics because I generally enjoy sciences, and I didn't want to take environmental or AP Bio but I wanted to take a science. Which left this and AP Chem so with the toss of a coin this won! I hope to learn stuff about space and how gravity and other f

  18. My name is Megan, and I'm seventeen. I have two brothers, and a golden retriever. I go camping a lot by the lake, and I enjoy going kayaking and boating. Also, my job is that I landscape over the summer. The reason I took physics was because I heard that this was a very interesting class to take. I hope to learn more about how things work in the universe in depth. I think that this class will also help me figure out if I want this to be apart of my career. I feel that this class will be a very important part of my senior year.

Thrilled to have a guitar player in class as well (I have a piano and three guitars at home, though I like to play loud and with two little ones I don't get many opportunities to play without interruptions!) Maybe I can bring the 12-string into class in the spring when we talk about resonance and talk you into a demonstration? And I'm jealous about having goats in the backyard. Growing up in a rural area we had plenty of neighbors and friends and my brother and I always loved playing king of the hill with the goats -- fun critters when you're a kid

  27. Good Evening Folks, I've received quite a few requests over the past couple months, and especially the past couple days, asking if I knew of an "outline version" of the AP Physics 1 learning objectives, essential knowledge, etc., organized by topic. I already had this created from working on the AP Physics 1 Essentials book as a chapter outline/roadmap correlated to the new AP 1 course, but had never bothered to put it in a user-friendly format to share. Well, until yesterday. Here it is: http://aplusphysics.com/educators/AP1Outline.html/ I understand this may not be the or

  31. 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.

  32. I'll give you some hints... First, you need to find the acceleration of the passenger as the car stops. To do this, first convert the initial speed of the car from km/hr to meters/second (http://www.aplusphysics.com/courses/regents/videos/Metric_System/Metric_System.html). Next, calculate the acceleration of the passenger: http://www.aplusphysics.com/courses/honors/videos/KinEqns_Hon/KinEqns_Hon.html Finally, once you know the passenger's acceleration, you can calculate the force using Newton's 2nd Law: http://www.aplusphysics.com/courses/honors/videos/N2Law_Regents/N2Law.html

  38. Time travel was inconceivable for Newton and his studies. But in Einstein's universe it has become a possibility. Science fiction about time travel inspired some of today's scientific ideas on the subject. So dreaming about alternate universes is ok no matter what field you study. Time travel to the future is possible, and it has happened. Like FizziksGuy said, astronauts have aged slightly less than we whose feet have stayed on earth. Now whether time travel to the past is possible, that is still debated, given certain physical conditions. Also, the study of time travel can be used to discov

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

I am studying the physics iBook "Physics - fundamentals and problem solving" , which is an absolutely amazing book by the way.. i had no idea one could teach through a book with a few videos and get the same results as a full on physics classroom. But anyway, there is a concept I am having trouble grasping. I understand that the force of the gravitational pull is mass times acceleration of gravity but what I'm having trouble with is what we are measuring when we stand on a scale.

  45. Three amazing students at Irondequoit High School have made a break through in the study of physics: By only using a stopwatch, a measuring tape, and a ball, the acceleration due to gravity has been calculated in a new and scientific way. Students measured the height from the floor of the classroom to the top of the ceiling with a measuring tape, and got 2.75 Meters. Holding the ball at the top of the ceiling, the three students dropped the ball and started the stopwatch at the same time. They measured that the time the ball took to hit the bottom of the floor was .64 seconds. Also, the initia

  47. Here's a problem I encountered sometime in the first few weeks of mechanics last semester. Post an answer if you get one, or ideas if you have them. I can provide hints as necessary (diagrams, possibly useful tools, etc.) maybe starting later in the week. At this point I am considering turning these around on a weekly basis, and so I'll probably post a solution Monday, 12/6. If Mr. Fullerton wants to give extra credit for such things, I imagine one would want to have it done before then for extra points. And show all work! Whether by beautiful here or by mailing be the back of a napkin,

  48. 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!

  49. Hi Elliot, It does seem too easy! And I understand why you think the answer must be R, because I did too when I first read the problem. Unfortunately, it's not that easy. As the puck slides down the surface of the sphere, it accelerates both out and down. At some point, the out component of the puck's velocity becomes so great that gravity cannot keep it on the sphere. I encourage you to convince yourself of this by rolling a marble off a basketball or some other similar surface. (Rolling adds extra complexity to the problem, but the same principle applies.)

  50. well you know 3 could because if you put 3N and 4N at 90 degrees there resultant would be 5N, so if you put the 5N in the opposite direction of the resultant the object would not move. 2 could work too, because if you set it up so that the 3 2N forces were 120 degrees apart, a peice, you would be able to achieve an equilibrium (draw it!) Now that i think about it, the answer is 1. 1 could not have an obtainable equilibrium. When you put the other ones at funky angles you can always achieve an equilibrium. BUT, for number 1, even if you had the 5N force going one way, and the 1N and 3N fo
