Instructions for the Mini-Cog Test. Administration. the Mini-Cog test is a 3-minute instrument to screen for cognitive impairment in older. adults in the primary care setting. The Mini-Cog uses a three-item recall test for memory. and a simply scored clock-drawing test (CDT). The latter serves as an âinformative. distractor,â helping to clarify scores when the memory recall score is intermediate. The. Mini-Cog was as effective as or better than established screening tests in both an.
The difference between speed and velocity is that velocity is speed  with a direction vector associated with it. It's that  direction vector that makes them different.  â¦  Speed is displacement (distance traveled) per unit time. Velocity  is displacement (distance traveled) per unit time in a given  direction.
The moving object has both velocity and speed. The scalar quantity speed is the distance travelled with respect to time. It shows how fast an object is moved. Instantaneous speed is the motion rate of object at a particular time period or moment.
