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.
Acceleration Due to Gravity. When any object is moved then its speed is changed which is called velocity while the change in velocity is acceleration. When it is changed continues then it is in accelerating condition which is called the rate of acceleration.
