IB Physics: Optional Practical: Balloon Drop

In this practical you will investigate the relationship between the terminal velocity and the size of a balloon. To measure the terminal velocity a balloon will be dropped so that it falls through the air far enough so that the weight is balanced by the drag force, this will be measured by analysing a video of the motion using LoggerPro.If the sphere travels through a fluid so slowly that the air flow can be considered...
