Motion-magnitude (§1.7)
The magnitude is not an intrinsic characteristic of motion, but is handy to represent.
The magnitude of a motion-occurrence coincides to the composition of that motion-occurrence.
A motion occurrence is a compound, its composition is made of other motion-occurrences.
Usually 2 MOs with different magnitudes are represented with different volumes. A bigger volume coincide to a bigger magnitude and to a more complex motion.

As a general rule, a motion-occurrence occurs as a combination of a number of other motion-occurrences. The components of which, are occurring with identical thrust or not, identical inclinations or not, and identical magnitudes or not.

Because at the limit, the fundamental motion components of a motion-occurrence are motion-quanta, any motion-occurrence is slower than its fundamental components.

We will encounter a great number of MO compositions; following is a specific case.
Both you and the car you drive on the highway have the same motion. Yet the car has a greater motion magnitude than you alone. The magnitude is represented in various ways in gravimotion either through the volume size of the MOs as introduced above or with a heavier motion occurrence contour line as on the figure; the magnitude could also be stated with relative numbers.
On this illustration, the 2 MOs have identical thrust and inclination; 6 of the left MO have been combined to make the right one; the contour lines of the 2 being 1 and 6 pixels wide. The 2 numbers representing the 2 magnitudes would be 1 and 6. The volume option would result in a bigger representation for the right one.
The 2 motion-occurrences represented are the motions of lighter and heavier bodies having the same speed and direction.
