Physics

Which of these is dimensionless?

Energy$/$work

SOLUTION
i) $\displaystyle \frac {Force}{acceleration}=\frac {kg.m.s^{-2}}{m.s^{-2}}=Kg$

ii) $\displaystyle \frac {Velocity}{acceleration}=\frac {m.s^{-1}}{m.s^{-2}}=s$

iii) $\displaystyle \frac {Volume}{Area}=\frac {m^3}{m^2}=m$

iv) $\displaystyle \frac {Energy}{Work}=\frac {J}{J}=1$
