Acceleration Analysis 
The Acceleration Time Analysis allows you to create graphs based on acceleration over time of up to 50 markers at a time. You can graph any of these markers relative to another marker. Additionally, you can graph the acceleration data relative to the starting position by selecting the Normalize option. This option will calculate an average of the first n frames and then subtract this velocity from each consecutive frame creating a “change of acceleration” graph.
The following formula is used to calculate the acceleration:
