 A Brief Introduction to Ancient Planetary Models   (Site not responding. Last check: 2007-10-09)
The principal motion of the planets was a regular west-to-east motion generally along the ecliptic, and the ancients had good values for the average (mean) speed of each planet.
For the Sun, the motion along the deferent is at the same speed and opposite in direction to the motion on the epicycle (measured relative to a rotating radius of the deferent), while for the simplest lunar model the motions are (slightly) different.
If the motion of the planet on the epicycle is now counterclockwise, then (within certain parameter limits) the planet will exhibit retrograde motion as required by the second anomaly, and by virtue of the eccentric deferent will also have the zodiacal anomaly.

 Projectiles, Parabolas, and Velocity Expansions of the Laws of Planetary Motion
The semi-parabola proves to be applicable to planetary motion as Galileo claimed, while the integral velocity variants of the laws of planetary motion and the implications of Galileo's application lead in turn to an examination of Galileo's "percussive origins" theory of planetary formation.
With these two provisos Galileo's semi-parabola may then be treated in terms of planetary motion with the mean distance R from the SUN represented by the "distance" down the vertical axis, and the inverse (Vi) of the mean planetary speed Vr represented by the "uniform velocity" along the horizontal axis.
Ac is the height and bc is the amplitude of the semi-parabola ab, which is the resultant of the two motions, one that of a body falling from rest at a, through the distance ac, with naturally accelerated motion, the other a uniform motion along the horizontal ad.

 Orbital resonance - Wikipedia, the free encyclopedia
One of the consequences of this resonance is the lack of bodies on highly inclined orbits, as the growing eccentricity would result in small pericenters, typically leading to a collision or destruction by tidal forces for large moons.
There are only a few known mean motion resonances in the Solar system involving planets or larger satellites (a much greater number involve asteroids, Kuiper belt objects, planetary rings and moonlets).

More like "Motion" kenpo jumps straight to the techniques and forms, and expects that the basics and principles will be absorbed out of their practice.
Non "motion" kenpo drills the basics until they are solid, then works with the techs and forms once the foundation is built.
I would say that "Motion Kenpo" is a term, in all fairness, that is used to describe it in a lesser manner, when compared to the "Non-Motion Kenpo", by the Non-Motion Kenpo practitioners.

 Babylonian Planetary Theory and the Heliocentric Concept
But while the latter all employed uniform circular motion and auxiliary devices of one sort or another to account for variations in planetary velocity, the Babylonians for their part appear to have determined fundamental period relationships subsequently applied in numerical schemes concerned with fixed, mean and varying orbital motion.
The attested subdivision of integer multiples of 360 degrees of uninterrupted sidereal motion by the number of synodic occurrences in the final Babylonian period relationships result in the determination of the mean synodic arcs.
The corresponding maximum, mean, and minimum synodic velocities for Jupiter were determined to be 38;02 degrees, 33;08,45 degrees and 28;15,30 degrees respectively, with a rate of change of velocity that was understood to increase (or decrease, depending on location) by 1;48 degrees per synodic cycle.

 Simplified Airplane Motion
By simplified motion we mean that some of the four forces acting on the aircraft are balanced by other forces and that we are looking at only one force and one direction at a time.
In reality, this simplified motion doesn't occur because all of the forces are interrelated to the aircraft's speed, altitude, orientation, etc. But looking at the forces ideally and individually does give us some insight and is much easier to understand.
In an ideal situation, an airplane could sustain a constant speed and level flight in which the weight would be balanced by the lift, and the drag would be balanced by the thrust.

 Retrograde Motion, Astrology Retrograde Motion, What does retrograde motion mean? Retrograde Motion Effects . . .
Retrograde motion is when it APPEARS as though a planet is actually moving in a backward motion due to the relation of the planet to the earth in its particular position at a certain point in time.
When a planet is said to be in retrograde motion, you can focus on the energy of the planet (like Mercury) and become more efficient in adopting its positive attributes.
So when Mercury is said to be in retrograde motion and it appears communications are going to heck in a hand-basket, this is merely our response and not what actually is. Again, look up Mercury or the retrograde planet in question on the planetary symbols page and adopt the positive attributes of that planet.
