1. The problem statement, all variables and given/known data So I am doing my lab, when I realize that I am not sure where the freefall occurs. I collect the data for a ball tossed in the air, and using a vernier motion detector, I found the graphs for displacement, velocity and acceleration (attached). second peak) 2. Relevant equations 3. The attempt at a solution I figured that the point where the ball was in freefall was when the acceleration graph was between the two maxima points, as marked on the graph, because this is where the only force that acts on the ball is gravity at those points. My partner on the other hand disagreed, and said that it is in freefall from the beginning of the first slope increase to the last slope decrease (at the beginning of the first peak to the end of the second peak (where it returns to become an unchanged acceleration after the ball has landed). Which one of us is correct and why?
