Non-uniform acceleration equation

  1. Jan 3, 2009 #1
    I need to know the non-uniform acceleration equation to determine final position given:
    initial position
    initial velocity
    initial acceleration

    I know that the equation with uniform acceleration is:
    x(f) = x(i) + v(i)t + (1/2)at^2

    I think the equation I'm looking for is the following, but I'm not exactly certain:
    x(f) = x(i) + v(i)t + (1/2)at^2 + (1/6)jt^3

    Re: Jerk

    Assuming that your jerk is constant, and that "a" in your equation is the initial acceleration [so by your notation, a(i)], then yes, you have the correct equation . =]
