rvalkass 5 Report post Posted August 17, 2010 In the UK we tend to call it jolt, so it doesn't really make sense following the title :PJolt (or jerk if you're an American) is the rate of change of acceleration (the first derivative of acceleration), ie. how quickly the acceleration of an object is changing. As acceleration is the rate of change of velocity, you can express jolt as the rate of change of rate of change of velocity, or the second derivative of velocity. As velocity is the rate of change of position, you can express jolt as the rate of change of the rate of change of the rate of change of position, or the third derivative of position.

I can't remember things right now, just got off a hot school bus. Share this post Link to post Share on other sites
