All things in the world are constantly moving. In all attributes of matter, motion is the most basic attribute, and other attributes are specific manifestations of motion attributes. For example, spatial attribute is the broad embodiment of physical activity. Time attribute is the persistence of material movement. Material movement form is varied, for each specific material movement form the corresponding form of energy, such as: and macro mechanical movement of the object corresponding to the form of energy is kinetic energy; The energy form corresponding to the molecular motion is heat energy; The energy form corresponding to the atomic motion is chemical energy; The energy form corresponding to the directional motion of charged particles is electric energy; The energy form corresponding to the photon motion is light energy; And so on. The motion characteristics of two objects can be described and compared by some physical quantity or chemical quantity. For example, two objects that make mechanical motions can be described and compared by physical quantities such as speed, acceleration and momentum. The current can be described and compared with current strength, voltage, power and so on. , but when the movement form phase at the same time, not two material movement characteristics only can describe and compare each other quantities is energy, the energy feature is moving all the common characteristics of material, energy scale is measure all movement in the form of a general. Thus, a new philosophical definition of energy can be made. Is one of the more common usage refers to various enterprises independent, non-profit organization (can be legal person, also can not), and can be further divided into companies and enterprises, the latter such as partnerships, sole proprietorship enterprise, individual industrial and commercial households, etc. This refers to the industrial handicraft industry from the feudal society to the early stage of capitalism. In the 16th century to the 17th century, some western countries of the feudal social system to the system of capitalism, capitalist primitive accumulation is accelerated, deprived of farmers' land on a large scale, make cottage industry collapse, sharply to capitalism works system transformation. Industrial handicraft industry is the embryonic form of enterprise.
