Derivation of an S.H.M. Equation

  1. Mar 12, 2008 #1
    Can anybody show me how to derive the equation for SHM. (T = 2 x (Pie) x (root m/k))

    Help would be greatly appreciated, as i need it for coursework

    No one will show you, but we will help you along it deriving it yourself.
    How can you model harmonic motion? What function would you use?

    it depends on cases. but I can give you the general way

    first you should find the relationship between the acceleration of oscillator and its displacement

    Then, by means of Newton's second law, F=ma
    find the a in terms of x if a is directly proportional to minus x
    then, for S.H.M a = -w^2x , where w is the angular frequency of motion
    w = =2pi/T
