Direction for expedience and rush

Expedience is the change in legerity per unit of length. Average expedience 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 expedience negative. Since increased motion is the default for expedience (as it is for acceleration), the default direction for expedience is in the direction opposite the motion. Negative expedience, or inexpedience, is in the direction of motion.

Rush, which is vass times expedience, is also in the direction opposite the motion. So the rush of levity is in the opposite direction as well. That is why cyclic motion in 3D time has a centrifugal rush. 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 rushes) come in direction pairs. So it is a matter of convention which direction is the primary one. The force toward the spatial center is primary in 3D space. The rush from the temporal center is primary in 3D time. Both directions are valid but one is primary.
