Homework Help: Newtons law concept question

  1. Apr 10, 2012 #1
    1. The problem statement, all variables and given/known data

    I just wanted to know if I was correct, when dealing with a newton law problem that has components.

    Ʃfx=0 and ƩfY = zero

    However when we add the forces together then we can use Ʃf=ma

    thanks




    2. Relevant equations



    3. The attempt at a solution

    1. All forces can be resolved into components whatever axis you choose.
    2. Component vectors also produce acceleration. Vector addition or subtraction produces the resultant acceleration.

    Thus it is applicable, f=ma for components or resultant forces.
