I was flipping through a physics text and some of the units seemed pretty 'crazy'. Just wanted to know if they can always be understood intuitively, like you can visualize what's going on
e.g. force, mass x acceleration, if I look at it as kg*m/s^2 then it doesn't really make sense to me
And whilst we're on the topic of dimensions/unit, if you have something like 20J/m^2/s and you simplify it mathematically so it reads 20J/m^2 s, does that still read 20J per square metre per second, or per metre second? If the latter, is that supposed to mean the same thing as metre per second? Metre second doesn't make sense at all!
