Question

which of the following is used as SI unit of velocity ? please explain

Answer 1

$\huge\mathsf{Hoy \ !!}$


$\mathsf{SI}$ $\rightarrow$ $\mathsf{International \ System \ of \ Units}$


$\mathsf{SI \ unit \ of \ Velocity}$ $\implies$


= $\mathsf{m{s}^{-1} \ or \ m/s}$


$\huge\tt{Explaination \ :}$


$\mathsf{As \ we \ know,}$


$\mathsf{Velocity \ = \ {\dfrac{Displacement}{Time}}}$


$\mathsf{Unit \ of \ Displacement \ = \ metre \ ( m )}$


$\mathsf{Unit \ of \ Time \ = \ second \ ( s )}$


$\therefore$


$\mathsf{Putting \ values}$


$\mathsf{Velocity \ = \ {\dfrac{metre}{second}}}$


$\mathsf{Velocity \ = \ {\dfrac{m}{s}}}$


$\mathsf{Velocity \ = \ m/s}$


$\mathsf{Or}$


$\mathsf{Velocity \ = \ m{s}^{-1}}$
