    Simulating motion in 1D with varying jerk?

    Hello, I am trying to accurately simulate motion in 1D with a jerk that is changing non-linearly, but predictably. As an arbitrary example, picture jerk increasing logarithmically over time. This is being done in the context of a physics simulation that is 'stepping' frame-by-frame (ie 60...

    Dependence between jerk and acceleration

    Wow, you described my problem exactly this time around and that looks to be exactly what I was missing, thanks! I will test this solution as soon as possible and post back to verify everything worked as it should. It's funny, I came up with the same constant ratio of distance in the first...

    Dependence between jerk and acceleration

    That clarified a lot, thanks! I wondered if you were just referring to half the motion, but I'm still shaky enough in some of this stuff that I didn't want to jump to assumptions. I'm still confused regarding my key question though...sorry if I'm dragging this out but I really appreciate...

    Dependence between jerk and acceleration

    Hi Gear.0, Thanks a lot for the quick response! It seems that I'm generally on the right track based on your suggestions. I'm confused by how you used the simplified distance equation for half the distance though, and was wondering if you could clarify a few things: I'm probably missing...

    Dependence between jerk and acceleration

    Hi Gear.0, You just hit the nail on the head in terms of a problem I am trying to solve. I am working on an algorithm to produce an s-curve acceleration profile to jerk from 0 acceleration/velocity to peak acceleration/velocity, then back down to 0 acceleration/velocity traveling a known...

    Solving for Constant Acceleration and Time in 1D Motion Problem

    Thanks for the input, rcgldr. What you are saying makes sense, although I think I am actually trying to do the reverse of what you are saying should work fine. Instead of calculating the constant jerk and elapsed time from a set of real world start and end metrics that I know works out, I am...

    Solving for Constant Acceleration and Time in 1D Motion Problem

    Hi Guys, I'm a programmer working on a hobby project (physics simulation), and came across this forum while looking for ideas related to a 1 dimensional motion problem I have. Hopefully someone can help me out (or at least point me in the right direction!). =) Homework Statement An...
