## What is the formula for velocity in economics?

The velocity of money can be calculated as the ratio of nominal gross domestic product (GDP) to the money supply (V=PQ/M), which can be used to gauge the economy’s strength or people’s willingness to spend money.

## What is aerodynamic velocity?

From Newton’s second law of motion, the aerodynamic forces on the body (lift and drag) are directly related to the change in momentum of the fluid with time. The velocity used in the lift and drag equations is the relative velocity between an object and the flow.

What is velocity of money in economics?

The velocity of money is the frequency at which one unit of currency is used to purchase domestically- produced goods and services within a given time period. If the velocity of money is increasing, then more transactions are occurring between individuals in an economy.

### How do you calculate the velocity?

Provided an object traveled 500 meters in 3 minutes , to calculate the average velocity you should take the following steps:

1. Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds ,
2. Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .

### What is aerodynamic give example?

Aerodynamics is the way air moves around things. The rules of aerodynamics explain how an airplane is able to fly. Anything that moves through air reacts to aerodynamics. A rocket blasting off the launch pad and a kite in the sky react to aerodynamics. Aerodynamics even acts on cars, since air flows around cars.

What are examples of aerodynamics?

A hot air balloon has lift because the hot air inside is lighter than the air around it. Hot air rises and carries the balloon with it. A helicopter’s lift comes from the rotor blades. Their motion through the air moves the helicopter upward.

#### How do you calculate velocity of money and nominal GDP?

It is calculated by dividing nominal spending by the money supply, which is the total stock of money in the economy: velocity of money = nominal spending money supply = nominal GDP money supply . If the velocity is high, then for each dollar, the economy produces a large amount of nominal GDP.

#### What is the formula to find final velocity?

Final Velocity Formula v_f = v_i + aΔt. vf=vi+aΔt. For a given initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity.

How is the aerodynamic force related to velocity?

The aerodynamic force equals a constant times the density times the velocity squared. The dynamic pressure of a moving flow is equal to one half of the density times the velocity squared.Therefore, the aerodynamic force is directly proportional to the dynamic pressure of the flow.

## How is velocity used in lift and drag equations?

The velocity used in the lift and drag equations is the relative velocity between an object and the flow. Since the aerodynamic force depends on the square of the velocity, doubling the velocity will quadruple the lift and drag.

## Which is the correct formula to calculate aerodynamics?

Aerodynamics Formulas. Deﬁnitions. p = The air pressure. (Pa = N/m2) ρ = The air density. (kg/m3) g = The gravitational constant. (Value at sea level is 9.81N/kg) (N/kg) h = The height above the earth surface. (m) V = The speed of the airplane relative to the air. (m/s) p.

How does the quantity equation relate to velocity?

The quantity equation shows that an increase in the quantity of money in an economy must be reflected in one of the other three variables: Th e price level must rise, the quantity of output must rise, or the velocity of money must fall.
