In science:

We should emphasize that current supernova data can constrain up to the third derivative of the scale factor which means the deceleration parameter q and the jerk parameter j can be determined.
Reconstructing K-essence
When the jerk J e t  vanishes, we have wt   w 0 and one can see that the transformation (1.20) reduces to the Wu transformation (1.14) for a constant-linear-acceleration frame F c x, in which the time axis is everywhere orthogonal to the spatial coordinate curves.

This constant jerk condition is consistent with recent redshift analysis which provides the lower bound for the jerk implying that Q > 0.
