Question 3.5: Determine the base units of: a pressure ( = force/area) b en...

a Pressure = \frac{F}{A}, F = ma, so pressure has base units \frac{kg  m  s^{-2}}{m^{2}} = kg  m^{-1}s^{-2}

b Energy = force × distance so energy has base units kg  m^{2} s^{-2}

c Density = \frac{mass}{volume} , so density has base units kg  m^{-3}
