How do you determine the acceleration of a freely falling object from a velocity time graph?
The velocity – time graph will be a straight line for a freely falling body. From the graph find v1 at the time t1 and v2 at the time t2. Since acceleration = change in velocity / duration of time for that change, find v2 – v1 / [ t2-t1] for any two values of t1 and t2 . Find the average of all such findings for a.
