momentum vectors |
Velocity is speed in a direction and represented by a vector. The length
of the vector is the speed. Mass times velocity is called momentum in
the physics text books. A vector that represents momentum (mass times
velocity) should have a volume to mean the mass. If the end points of
the vector are four-dimensional points in the Synergetics coordinate
system the end points are shown as regular tetrahedrons with vertexes in
the point lattice of closest packed equal diameter spheres. The vectors
will have a volume, length, and direction.
How are momentum vectors represented without Synergetics coordinates now?

Displacement is a vector. Velocity is displacement in unit time.
Time is not a vector, mass is not a vector, they are scalars.=20
Therefore by leaving out time and mass, displacement is all you need=20
in what is after all only a visual aid to understanding.
For force:
Three horses pull north, four horses pull east, the resultant is as if =
five=20
horses pulled east-by-northeast (53 degrees), and that is displacement.
(4,0,0) + (0,3,0) =3D (4,3,0)
For velocity:
A horse walks east-by-northeast (53 degrees) at 5 mph, it arrives at =
(4,3,0) after=20
one hour.
Why would you want a thick fat broad line representing the load on=20
it's back?

How do you represent the same displacement in unit time of different
masses?

Easily. Magnitude and direction.
No "synergetics" ***** required.
