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.
Full Answer. As the height of the ramp increases, the height of the object placed at the top of this ramp does too. An increase in height of an object from a surface in the presence of a gravitational field corresponds to an increase in the potential energy of the object. When the object is left to roll or skid down the higher, more inclined ramp to the surface, this higher potential energy can be converted into correspondingly higher kinetic energy. Because kinetic energy is calculated from the mass of an object and its speed, the higher the ramp, the faster an object rolling or skidding down the ramp will be, assuming the mass of the object remains the same.
