A stock variable measures a variable at a specific point in time, for example the amount of foreign direct investment at the moment in a specific country. This variable is only denominated in terms of a currency. A flow variable on the other hand looks at the measure of a variable over a period of time, for example the GDP of a country as this variable looks not only at a fiscal amount but also also a time amount (in this case the amount of money spent in the economy over the course of a year).

A variable that depends on an instant rather than a flow of time
A stock variable 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). Flow is roughly analogous to rate or speed in this sense
examples of stock variables and flow variables stock: saving,capital,labour force, wage rate, flow: income,investment,balance of payment
Investment spending is a flow variable. It denotes the amount of money spent on purchasing new physical capital or increasing the stock of existing capital during a particular period of time, typically a year. It is different from the stock variable, which represents the total accumulation of physical capital at a given point in time.
No, savings is a stock variable. It represents the accumulation of past income that has not been spent. Flow variables, on the other hand, measure the rate at which a quantity changes over a specific time period.
No, it is a stock measure, as in, it is measured at a given point in time. Income on the other hand IS a flow measure, you must specify a time period for it ex. income per month or per year.
