Direction for rapidation and release

Rapidation is the change in legerity per unit of length. Average rapidation is (u2u1)/Δs. If the second legerity is faster than the first, the time interval is shorter and the legerity is lower in value, which makes the rapidation negative. Since increased motion is the default for rapidation (as it is for acceleration), the default direction for rapidation is in the direction opposite the motion. Negative rapitation, called derapidation, is in the direction of motion. Zero rapidation is unrapidated.

Release, which is vass times rapidation, is also in the direction opposite the motion. So the release of levity is in the opposite direction as well. That is why cyclic motion in 3D time has a centrifugal release. And that is why there is levity, not gravity, in 3D time although the motion is the same.

Newton’s 3rd law shows that forces (and releases) come in direction pairs. So it is a matter of convention which direction is the primary one. The force toward the stantial center is primary in 3D space. The release from the temporal center is primary in 3D time. Both directions are valid but one is primary.
