All naked entities and constructs have a kinetic rest speed
The definition of the kinetic rest speed is:
The propagation speed at which the entity or construct has no kinetic energy in its electromagnetic manifestations. It is the speed at which the entity of construct emerged.
For the photon and neutrino, this kinetic rest speed is the speed of light.
For the construct electron, this speed is significantly lower.
For clarification, the illustration of the naked electron is:

The speed limit for any manifestation of an entity is the speed of light. In the electron, we have the electric manifestation of the photon active in the direction of propagation of the construct. Therefore, the speed of the electron is reduced to avoid breaching the limit of the speed of light. The reported speed of a naked electron is at some 2,2.10³ m/s or about 0,01% of the speed of light.
A check reveals that the amplitude of the electric manifestation at 0,34 fm, alternating at a frequency of 1,54.10²³ Hz, is already active at almost the speed of light. In the electron, the electric manifestation of the photon is rotating in the direction of propagation. Therefore, the reported speed of the naked electron at 2,2.10³ m/s is well understood.
While forming the electron, there is no other interference, and therefore, this speed of 2,2.10³ m/s is likely the kinetic rest speed of the electron.
The rest speed for the dodecahedron is zero relative to the speed of light.
Whenever external forces cause a construct to change speed, it reacts to prevent breaching by introducing vibrational compensation through one or more of its constituent entities. During acceleration, the construct builds up these vibrations, exhibiting inertial behavior. Once the acceleration ceases, the vibrational compensation continues, establishing a new stable state for the construct. This new stable state remains intact until there is further external interference.
That process is the inertial behavior of constructs.
