I Want to learn physics

  1. Jan 20, 2009 #1
    I want to learn physics but here are the problems: I am only 14(almost 15) and i never did my math homework or science either so i cant get into an accelerated class(i can do the work in the higher classes thoguh, im smarter than all the other kids)the second problem is i dont plan on going to collage because physics isnt my what im into the most so i dont want to make a career out of it, so what do i do abought it?

    Maybe start with this book, "Thinking Physics"


    It's pretty cheap in the paperback edition, and it's a fun and interesting intro to Physics, targeted at about your age level, with lots of practical things to try out. I bought a copy for my 14/15 year old son for Xmas.

    Anything for free? i downloaded some other books in pdf but there too hard i dont know geometry or trigonometry or clacules(i know i miss spelled that)

    Edit: I did Learn alot abought physics and astronomy, its not like i dont have a clue abought it.

    I second that, great book. Tell your parents to buy it for you or get it from the library.

    Is it possible to leanr geometry online? i take geometry next year but i want to see if I can leanr it now so i can start to read some of those books i downloaded.

    At fourteen it's too early to know what you want as a career or even what you plan on studying beyond high school (if anything), but you should be encouraged to explore your interests. If you're really interested in physics, I would suggest that you talk to a guidance councilor at your school and see if you can get into the class that you want to take.

    Secondly, it's never too late to change your study habits. If you really plan on learning physics - there's a lot of homework involved.

    i dont mide doing homework the only reason i never did it before was because it was too easy.

    If/when you go to college, it won't be.

    So as i asked beofre, is there a way I can learn geomerty without waiting for next years math class?

    how are your algebra skills?

    sorry this bothered me "about"

    Your perception of physics seems off. Judging by your current math level I would assume whatever physics class you took was tailored to your level. This certainly wont be the case in college. Anyway, dont let your early exposure stear you away from physics as your perception of it will undoubtably change. For the better or the worse, I cannot say.

    As for learning geometry. If you didn't have trouble with algebra I would assume you will do fine in geometry. There are many online lectures you could view to supplement your text if you have one. You could inquire into which text you will be using next year and use that. Although if your math cirriculum is like mine was untill you take precalculus you may be using several small soft bound books throughout the year, none of which are organized like a text book. With physicsforum, textbooks, lectures, the internet, teachers etc, you should be able to learn geometry.

    Keep in mind to learn math you actually have to DO it. People often think of elaborate methods of how they can learn but never actually DO the work. Get a book and DO the math!

    What about physics do you like exactly? If you weren't doing math homework because it was too easy, why not do the homework and then get into accelerated classes where you should be if the current is too easy. I am a senior in high school and took my first physics class last year with not much knowledge about it before. You will be surprised how much math is in physics. I consider physics to be another math class, just more applied, and its harder in many ways because of the concepts you have to think of. I must say though that I don't know anyone who is good at physics or even really enjoys it without having a very firm grasp on alot of math.

    Also what about geometry do you need to know? You should be able to do alot of physics with simple trig like sin/cos functions.

    That is an interesting christmas present berkeman! I kinda chuckled at the idea of opening a physics book for christmas, but at the same time I honestly wish my parents would have got me involved in physics when I was younger.

    Great Christmas present! In all seriousness, I think the world would be a much better place if more parents gave thoughtful gifts like this rather than the newest ipod/games/etc.

    Nabeshin, while I completely agree that books about physics=great, so do ipods :smile:

    Ipod touch was a great christmas present

    I completely disagree with this statement. Without trying to sound cocky, when it comes to algebra, I rank as the top of my year. But as for geometry, well, I can barely pass those exams. It's all about what interests you, and geometry never caught my fancy.
    For beginner geometry, there is no need for a lot of skill in algebra, but this changes slightly as the geometry becomes more complex.

    I second that!
