SUMMARY

The non-uniform acceleration equation for determining final position is accurately represented as x(f) = x(i) + v(i)t + (1/2)a(i)t^2 + (1/6)jt^3, where x(i) is the initial position, v(i) is the initial velocity, a(i) is the initial acceleration, j is the constant jerk, and t is time. This formula extends the uniform acceleration equation by incorporating the effects of jerk, which is the rate of change of acceleration. The discussion confirms that the equation is valid under the assumption of constant jerk.

I need to know the non-uniform acceleration equation to determine final position given:
initial position
initial velocity
initial acceleration
jerk
time

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

Thanks:smile:

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 . =]
