A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by a force. At any instant of time, the net force on a body is equal to the body's acceleration multiplied by its mass or, equivalently, the rate at which the body's momentum is changing with time.
By an accounting identity, Country A's NCO is always equal to A's Net Exports, because the value of net exports is equal to the amount of capital spent abroad (i.e. outflow) for goods that are imported in A. It is also equal to the net amount of A's currency traded in the foreign exchange market over that time period.
The sectoral balances equation says that total private saving (S) minus private investment (I) has to equal the public deficit (spending, G, minus net taxes, T) plus net exports (exports (X) minus imports (M)), where net exports is the net spending of non-residents on this country's production. Thus total private saving equals private ...
The net exports is the part of GDP which is not consumed by domestic demand: N X = Y − ( C + I + G ) = Y − Domestic demand {\displaystyle NX=Y-(C+I+G)=Y-{\text{Domestic demand}}} If we transform the identity for net exports by subtracting consumption, investment and government spending we get the national accounts identity:
There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.
The moving ball can then hit something and push it, doing work on what it hits. The kinetic energy of a moving object is equal to the work required to bring it from rest to that speed, or the work the object can do while being brought to rest: net force × displacement = kinetic energy, i.e., =
Country foreign exchange reserves minus external debt. In international economics, the balance of payments (also known as balance of international payments and abbreviated BOP or BoP) of a country is the difference between all money flowing into the country in a particular period of time (e.g., a quarter or a year) and the outflow of money to the rest of the world.
The notion of the balance of trade does not mean that exports and imports are "in balance" with each other. If a country exports a greater value than it imports, it has a trade surplus or positive trade balance, and conversely, if a country imports a greater value than it exports, it has a trade deficit or negative trade balance.
