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, it a flow variable
It is a flow.

flow
In the circular flow, investment spending does not equal saving because goods and services are still needed therefor consumption still requires spending in return pays taxes and companies.
yea
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).
examples of stock variables and flow variables stock: saving,capital,labour force, wage rate, flow: income,investment,balance of payment
yes
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
Planned investment is called an injection because it refers to new spending or investment that is added to the circular flow of income and expenditure in an economy. It injects additional income and spending into the economy, stimulating economic activity and potentially increasing aggregate demand. In contrast, unplanned changes in inventory levels are called leakages because they remove income and spending from the circular flow.
