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 [9] 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.
