Temporally and logically it has the sense of total distance from the first element to the last within an interval anchored at a unique step. The shorter the interval the more concentrated the sequence.
Geometrically its strongly associated with circularity, concentrism and regularity, as real forces act with omni-directional non-linearity, rather than in a rectilinear fashion along the cardinal directions.
Physically it is synonymous with density. Define a boundary. Count what's inside. The higher the count, the higher the concentration.
Coherence is synonymous with power. The more that things go in the same direction, in the same step, the larger an effect they have.
Consider a modern rocket engine. Many nozzles ejecting heated matter in parallel. Point them away from one another and the acceleration imparted weakens.
Coherence imports the idea of an axis, an imaginary line which every element's trajectory runs parallel to
Physically it's a pattern of things that move together in sync like a lot of copies in different places at the same time.
Temporally and logically it's a chain of events that follow one after another, such that you can't separate them.
Physically its the alignment of moving patterns, such that they travel together like a pack of synchronised swimmers, each in step with one another.

What if a robot could grab objects like a chameleon catching a bug?
Festo’s FlexShapeGripper uses compressed air, water and an elastic silicone cap that wraps around objects of different shapes.
Unlike traditional rigid grippers, it can adapt to different geometries without manual reconfiguration.
