Question

Q.Speed and velocity do not have same dimensions then what are their dimensions?

Answer 1

Ahoy !!! 
you are CONFUSED I THINK  !!!!

Speed = distance / Time 

and distance means length  we calculate in Meters , Km , mm , cm etc. 

Time we calculate it in sec , hour , min etc..

Now Unit of Speed = m/s 

And the Dimension formula = M L⁻¹ 


Same in the case of the displacement which we calculate as a parameter of the length 

velocity = Displacement / Time 

unit = m /s 

Dimension Formula =  M L⁻¹
