Homework Help: Facts I need to learn in Physics besides the formula

  1. Mar 1, 2012 #1
    1. The problem statement, all variables and given/known data

    I would want to know how free fall, acceleration and friction works ?
    I mean it like there is a greater friction when an object is heavier
    or an object is possible to have zero velocity but nonzero accelaration.
    I need those kinds of things to study :D

    2. Relevant equations
    If there is like the derivation of the formulas :D

    3. The attempt at a solution

    Actually this question is really in general and i would want to learn more about physics, its effect and the applications. Please help me :D tnx in advance guys

    if it isn't possible for you to take classes on this stuff and you don't have the ability to go out and buy yourself an introductory physics text book, I would suggest going to khanacademy.org for a great, free online source of learning material related to physics, and a whole lot more
