# Worlds of motion

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.
