1. In Current Science, motion is a change in position of an object with respect to time. Motion is typically described in terms of velocity, acceleration, displacement and time. Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to another reference frame with time.
2. In Neu Theory, motion is number  of the elementary forms of nature. Motion is rise energy bound to matter. Motion is a physical displacement relative to a specified accelerating system of reference at speeds less than the speed of light:
- The straight vector kinetic motion of physical objects follows the 2nd law, with its energy decreasing with natural acceleration.
- The bent vector electro-kinetic orbital motion of electrons in atoms follows the 1st law, with its energy maintained with natural acceleration.
- The bent vector spinfield orbital of the satellites of celestial bodies follows the 1st law, with its energy maintained with natural acceleration.
