Question

The SI unit of velocity is ____.

Options
  • A

    m/s

  • B

    1/s

  • C

    m/s2

  • D

    m/s3

Explanation

Correct Option: A

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).
