2025-10-10.3_requisites for movement

what are the requisites for the (meta-)physical process of movement?: time, space, difference and fluidity.

for example: a fly flies. for this process to exist/happen the requisites are: a few different moments in time in which it happens, a few different places within space for the fly to fly between and the general capacity to do so (i.e. to move), which i denote as fluidity.
