[acceleration]

Acceleration is a measure of how fast velocity changes. Acceleration is the change of velocity divided by the change of time. Acceleration is a vector, and therefore includes both a size and a direction.

In this case the logger mesures velocity two times, both infragates once. Than it subtracts the second velocity from the first velocity and devides with the difference of the two times.

a = (v1 - v0) / (t1 - t0)

Measured in m/s2
