"It is well known that the first derivative of position (symbol x) with respect to time is velocity (symbol v) and the second is acceleration (symbol a). It is a little less well known that the third derivative, i.e. the rate of change of acceleration, is technically known as jerk (symbol j). Jerk is a vector but may also be used loosely as a scalar quantity because there is not a separate term for the magnitude of jerk analogous to speed for magnitude of velocity."

Kiihtyvyyden ensimmäinen aikaderivaatta eli paikan kolmas aikaderivaatta on jo pitkään tunnettu suomen kielessä nykäyksenä, joka varsin hyvin kuvaa ilmiön luonnetta.
