Money is not only cash, but also cash plus some tangible and intangible assets. The nature of currency contract determines that it can have different forms, such as general equivalent, precious metal currency, paper currency, electronic currency and so on. It can be used as a medium of transaction, storage value, deferred payment standard and accounting unit
There are mainly the following definitions of money:1
2. Goods that act as the medium of exchange, value, storage, price standard and deferred payment standard
3. Excess supply or demand will lead to excess demand or supply of other assets
4
5. No interest is needed to be paid as the current assets of public net wealth
6, the most liquid assets related to national income, etc

the functions of currency include value scale, circulation means, storage means, payment means and international currency
1. Value scale when money implements the value scale, it does not need real money, it only needs conceptual money
the memory of value scale can be just like the ruler measuring the length itself has the length, and the weight weighing things itself has the weight, so the currency measuring the value of goods itself is also a commodity and has value. For example, a bicycle is worth 1g of gold, which is the function of monetary value scale
2. Currency is the medium of commodity exchange. In the process of commodity exchange, the seller converts the commodity into money, and then uses money to buy the commodity. Here, money plays the role of medium of exchange and performs the function of means of circulationfor example, when you buy something, if you need to pay money and deliver it, money will be transferred from your own hands to others, which is the function of circulation means
Storage means the money used as storage means should be metal money of sufficient value (such as gold and silver bars, etc.) However, there are different views on whether paper money can be used as a means of storage. The traditional view is that only the real and valuable metal currency can be preserved and used as a means of storage. If the amount of paper money issued does not exceed the amount of metal money needed in commodity circulation, the stable social purchasing power will be maintained The means of payment is the function of money as an independent form of value in unilateral movementfor example, using money to pay off debts, pay taxes, pay wages and rents, etc
Due to the occurrence and development of international trade, the circulation of money goes beyond the scope of a country and plays a role in the world market, so money has the function of world currency For example, the international community takes the US dollar as the currency of payment and settlement, and the US dollar is beyond its domestic scope and can be used in the world, which is the function of the world currencyas for the means of circulation, real money must be used in the process of currency circulation. Paper money is just a form of expression, that is, the undertaker
the lifting force is elastic on the surface, but electromagnetic force in essence, that is, the electromagnetic force of muscle contraction. The stretching effect of muscle is actually the result of electromagnetic force between molecules (muscle is composed of cells, cells are composed of various molecules)
as long as the electromagnetic force of muscle is strong enough, Then the force proced by muscles can be much greater than that of gravity.
so the & quot; Lifting force (actually, it's not rigorous) & quot; The reason is the result of the change of the body's chemical energy, which has nothing to do with the elasticity of the ground to the body. It can be said that the elasticity of the ground to the body is triggered by objects and people together, rather than generated on their own initiative
