How do we know what the derivative is in terms of when we are using the two different types of derivative notation? (the dot vs the apostrophes)

Usually the dot means derivative with respect to time i believe

@jifengy Yes, @ngandhi has it right. Take a look at the blue text, which defines the notation. Here, each dot over a variable indicates a time derivative; each prime indicates a space derivative (in 1D). This becomes especially useful when you have mixed time/space derivatives.
