Question

what is the difference between stock and flow??​

Answer 1

$\huge\underline\mathfrak\green{Answer}$

• A stock is measured at one specific time, and represents a quantity existing at that point in time (say, December 31, 2004), which may have accumulated in the past.

• A flow variable is measured over an interval of time. Therefore, a flow would be measured per unit of time (say a year).
