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.
5. An object of mass 30 kg is falling in air and experiences a force due to air resistance of 50 newtons. 1  Determine the net force acting on the object and. 2  calculate the acceleration of the object. ans0405 (39.0K).. For a person who has a mass 60 kg, calculate the weight in newtons and in pounds. ans0409 (37.0K). 10. An object of mass 10 kg is accelerated upward at 2 m/s 2.
