Derivatives

A useful thing to do with position data (e.g. from a motion capture system) is to calculate the first and second derivatives, which will give you the velocity and acceleration respectively. But it is possible to continue calculating derivatives. Here are the names for the first 10 ones:

  • original: position
  • velocity (1st)
  • acceleration (2nd)
  • jerk (3rd)
  • snap / jounce (4th)
  • crackle (5th)
  • pop (6th)
  • Lock (7th)
  • Drop (8th)
  • Shot (9th)
  • Put (10th)

Whether these are useful or not is another question…
