When mass motion, the size and direction of the instantaneous velocity can change, and in order to reflect the speed and direction of its change, the average acceleration needs to be introduced. The average acceleration only reflects changes in mass velocity over time. Obviously, the shorter the time, the more the average acceleration can finely reflect the change in velocity. The ratio of the amount of velocity change over time to this time is the average acceleration over that period. It is a description of the movement over a period of time, describing the movement over a period of time.

Average acceleration ( last velocity - initial velocity) / this time

a(bar)-1v/t-unit: meters per second square seconds Symbol: m/s2 or m.s-2
