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.
Speed is the distance an object travels per unit of time. Speed can be expressed as kilometers per hour (km/hr), meters per second (m/s), and so on. In most cases, objects donât travel at a constant speed. Therefore, the average speed is used to describe the motion. s = speed, t = time, and d = distance. Acceleration is the rate at which an objectâs speed changes. Acceleration can be expressed as meters per second per second (m/s/s or m/s2). Forces such as gravity, air resistance, and friction can cause an object to decelerate (decrease speed over time).
