*Kinecosm* is the world of motion, which is the subject of kinematics. Since the extent of motion has two measures: length and duration, the kinecosm has two subworlds: *Length space* is the three-dimensional world of length, which is commonly called *space*. *Duration space* is the three-dimensional world of duration. *Chorocosm* is length space with time. *Chronocosm* is duration space with stance.

*Position* is an index to a point of the kinecosm. *Location* is an index to a point of length space. *Chronation* is an index to a point of duration space. *Displacement* is the vector from one point to another in length space. *Dischronment* is the vector from one point to another in duration space.

*Time interval* (*distime*) is the duration space metric. *Distance* is the length space metric. *The time* is the time interval *from* an anchor point of duration space (e.g., from the origin). Negative time is the time interval *to* an anchor point of duration space. *The stance* is the distance *from* an anchor point of length space (e.g., from the origin). Negative stance is the distance *to* an anchor point of length space.

The rate of motion is measured either as a displacement per unit of time, which is *velocity*, or as a dischronment per unit of distance, which is *lenticity*. The rate of velocity is measured either as a vector change of velocity per unit of time, which is *acceleration*, or as a vector change of duration per unit of distance, which is *relentment*.

Mass and vass are inverse weights. Weighted rate of motion is measured either as mass-weighted velocity, *momentum*, or as a vass-weighted lenticity, *levamentum*. These equal the velocity integral of mass and the lenticity integral of vass, respectively. The double integral of a mass is the *kinetic energy* (i.e., half the mass times velocity squared). The double integral of a vass is the *kinetic lethargy* (i.e., half the vass time lenticity squared).

*Dynacosm* is the world of motion and its causes. The main cause of motion is measured either as a *force*, which is the time rate of change of momentum or as a *release*, which is the distance rate of change of levamentum. *Impulse* is a force applied over a time, and *remove* is a release applied over a distance. *Work* is a force applied over a displacement. *Repose* is a release applied over a dischronment. Work and repose are inverses. *Power* is the time rate of work done. *Placidity* is the distance rate of repose effected.

*Gravitation* is the mutual force that all bodies have, which is directed toward their mutual centre of mass. *Levitation* is the mutual release that all bodies have, which is directed toward their mutual centre of vass.
