The unit of velocity in MKS system can be:
Correct answer: C. Meter/sec
- A. Centimetre/sec
- B. Centimetre/sec2
- C. Meter/sec
- D. Meter/sec2
Explanation
The meter/second (m/s) is the standard unit of velocity in the MKS system. It represents the distance traveled in meters per unit of time in seconds. The formula for velocity (v) is v = distance/time, and when the distance is measured in meters and time in seconds, the unit is meters per second.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
