Click For Summary

Discussion Overview

The discussion centers on the physical interpretation of higher-order derivatives, specifically the second, third, and fourth derivatives, in relation to their meanings in physics and real-world applications.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants note that the interpretation of higher-order derivatives depends on the original mathematical object and the variable with respect to which the derivative is taken.
  • One participant states that the second derivative of position with respect to time is acceleration, the third is jerk, and the fourth is jounce.
  • Another participant questions the terminology of "jerk," suggesting it relates to a sudden change in acceleration and seeks clarification on the term's usage.
  • A further contribution explains that jerk can be understood through real-world scenarios, such as driving a car, where the progression from position to velocity to acceleration to jerk illustrates the concept of changing acceleration over time.

Areas of Agreement / Disagreement

Participants express varying interpretations of the terminology and concepts, indicating that multiple views remain on the physical meanings and implications of higher-order derivatives.

Contextual Notes

The discussion includes assumptions about the definitions of derivatives and their physical meanings, which may not be universally agreed upon. The explanations rely on specific contexts, such as motion, which may limit their applicability.

hi guys,does anyone knows what is the physical interpretation of second(third, fourth,...) derivative?
 
Physics news on Phys.org


That depends on a number of things, such as what the original mathematical object represented and what you are taking the derivative with respect to. For instance, the second derivative of position with respect to time is acceleration, the third is jerk, and apparently the fourth is jounce (http://en.wikipedia.org/wiki/Jounce)..
 


Wiki explains jerk as a change in acceleration.

Why is the word 'Jerk' used?I understand in my (limited?) English knowledge that jerk can mean a sudden move.
Like a spike?
 


well i think what he meant by jerk is just to explain the idea what would happen if the acceleration is also changes with time. try to think for real time situation..like driving a car...first derivative mean velocity,second means acceleration and then derivation of acceleration is jerk.so if u will the acceleration again and again u will have jerks...
