"Velocity of Money"

The velocity of money is the average frequency with which a unit of money is spent in a specific period of time. Velocity affects the amount of economic activity associated with a given money supply. When the period is understood, the velocity may be present as a pure number; otherwise it should be given as a pure number over time. In the equation of exchange, velocity of money is one of the key variables determining inflation.
If, for example, in a very small economy, a farmer and a mechanic, with just $50 between them, buy goods and services from each other in just three transactions over the course of a year


Mechanic buys $40 of
corn from farmer.
Farmer spends $50 on
tractor repair.
Mechanic spends $10 on
barn cats from farmer

then $100 changed hands in course of a year, even though there is only $50 in this little economy. That $100 level is possible because each dollar was spent an average of twice a year, which is to say that the velocity was 2 / yr.
