All 3 packets had different accelerations and changes in acceleration due to wind resistance, and center of mass/density. Because all three packets are made differently they have different centers of mass as their density and mass is different. The paper like packet can make it reach terminal velocity faster if the center of mass is close to the center and is not dense enough to prevent it from flipping side ways. Acceleration was mainly affected by shape, density, and weight distribution.
