Operational Definitions/Measurement System Analysis. The focus for this month is on operational definitions. Operational definitions are one key to good data collection. They are a necessary, although not sufficient, condition for good data collection. Plus, we will look at how control charts can be used to evaluate the measurement system.
Air resistance induces a drag force on any body that falls through any atmosphere other than a perfect vacuum, and this drag force increases with velocity until it equals the gravitational force, leaving the object to fall at a constant terminal velocity.
The Terminal velocity depends on a few properties of the object falling and the medium that the object is falling through. 1. The mass of the object F=m*a where in this ca â¦ se a = gravity A balloon the size of a bowling ball and a bowling ball do not have the same terminal velocity due to the mass of each.
