Question

_______ is the SI unit of speed.

Answer 1

Speed

1. The rate of change of position of an object in any direction is known as speed.
2. We can calculate the speed as the ratio of distance to the time covered by the object.
3. Speed is a scalar quantity as it only has direction and no direction.
4. $Speed=\frac{dis\tan ce}{time}=\frac{meter}{second}$
5. SI unit of speed = $m{s}^{-1}$

$\mathit{m}\mathbf{/}\mathit{s}$ is the unit of speed.
