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.

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.
Your choice of answer to this question determines what you calculate â speed or velocity. 1  Average speed is the rate of change of distance with time.  Average velocity is the rate of change of displacement with time.
