Time refers to the motion of events which occurs in irreversible succession.
Motion is a change of location which occurs at various rates of speed.
Speed is the rate of change, and the rate is determined by the force which causes the change.
Periodic motion is a continuous flow of energy or momentum which is based on the recurrence of the same state. A period is recognized as complete by the return of a system to its nearly original state.
Periodic motion describes a cyclical or angular path of cause and effect which is determined by an initial force and maintained by the momentum of its nearly continuous recurrence. Periodic motion tends toward a gradual state of disorder.
Periodic motions include various oscillations, cycles, and wave patterns which may occur at regular or irregular time intervals.
Cyclical motions occur at every order of magnitude and scale, ranging from atomic and subatomic particles, to planets, stars, and galaxies.
Aperiodic motion is a discontinuous flow of energy or momentum which forms an interactive chain of events, arranging itself ultimately into random disarray.
Aperiodic motion describes a linear path of cause and effect, and is characterized by a rapid increase toward disorder.
Linear motions include various interactions and cascades, including patterns of convergence and divergence, collisions, and explosions.
There is no cyclical path of motion which is completely free from causal influence and which returns to its exact point of origin. Conversely, there is no linear path of motion which is free from the recurrent actions of its constituent parts. Events which occur at every order of magnitude embody various combinations of linear and angular motions, depending on the kind of event and the forces which influence it.
In general, the motions of events are influenced by forces of gravity, electromagnetism, and the nuclear forces, which result in the formation of interactions, cascades, oscillations, cycles, and waves of various kinds.
If you believe that the shell of a snail, or the scroll of a violin is the same shape as your inner ear, shut your eyes, and imagine that you are a small creature, spinning slowly in a counterclockwise direction, while translating through space at supersonic speed. – J. H.
