This means every second, their speed increases by 0.5 m/s. Acceleration is defined as the rate of change of velocity. Acceleration is the change in velocity per second and is measured in m/s 2.

ABSTRACT: The coupled Gross-Pitaevskii equations are the basic model describing the phenomenon of Bose-Einstein condensation. Therefore, the research on the coupled Gross-Pitaevskii equations is very ...
