Homework Help: Simple Pendulum

  1. May 25, 2009 #1
    1. The problem statement, all variables and given/known data
    Is there an actual formula for the acceleration of a simple pendulum.
    I know that the distance is angular displacement=angular amplitudesin(wt+phase constant) and the velocity is angular velocity= Length of String* w*angular amplitude cos(wt+phase constant)


    2. Relevant equations



    3. The attempt at a solution

    Hi there,

    I am sure you can even find out yourself. You just need to apply Newton's second law. With simple calculations, you can find out the acceleration of a simple pendulum.

    Cheers

    Damn,

    Now that's great help. I was going to make a little drawing like that. But I guess you have the answer right there.

    Cheers
