Question:
Find the dimensions of
a) linear momentum
b) frequency
c) pressure
Solution:
a) Linear momentum = mv
Dimension $=\left[\mathrm{MLT}^{-1}\right]$
b) Frequency $=1 / T$
Dimension $=\left[\mathrm{T}^{-1}\right]$
c) Pressure = Force/Area
Dimension $=\left[\mathrm{MLT}^{-2}\right] /\left[\mathrm{L}^{2}\right]=\left[\mathrm{ML}^{-1} \mathrm{~T}^{-1}\right]$
