The SI unit for speed is ______

The SI unit for speed is m/s.


Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

  • Speed is directly proportional to distance when time is constant: v ∝ s (t constant)
  • Speed is inversely proportional to time when distance is constant: v ∝ 1/t (s constant)
  • There are four types of speed and are uniform speed. Variable speed. Average speed. Instantaneous speed.
