The SI unit of velocity is _.
Correct answer: A. m/s
- A. m/s
- B. 1/s
- C. m/s2
- D. m/s3
Explanation
Correct Option: A(unit) m/s is the SI unit of velocity.The SI unit of velocity is meters per second (m/s). Velocity is defined as the rate of change of displacement with respect to time. It represents how fast an object is moving and in which direction. The SI system uses meters (m) for displacement and seconds (s) for time, so the unit of velocity is expressed as meters per second (m/s).

About Displacement and Velocity
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.
