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 height at which the final velocity becomes 0 is the maximum height that the object can reach for a given initial velocity. For a vertical throw, the acceleration due to gravity formulas can be formed by plugging in v = 0 and g = -g in the fundamental equations of motion.
