Acceleration Rate

Change of Velocity, or the increase of rate at which a ship can travel usually expressed in Light Time (Light Seconds,Hours, Days, Weeks, Months, Years, Decades.) Rates which are below a Light Year, can often be expressed as Impulse. Sub Impulse speeds are speeds which are less than 1/10th of 1 Light Year and expressed as such.

Example : 2 Light Seconds has an acceleration of of 2 LS/S, which increases the total velocity by 2 Light Seconds per Second.
