v=s/t time communicates a limit quantity and an observed quantity, and the transformation of the units is group-symmetric, and to a certain extent, the three are interchangeable. Pen & Fun & Pavilion www.biquge.info

g=mg has a conversion of the average amount

p=m/v density is analogous to probability density, volume is probability space, and mass class is the overall information quantity; Density is analogous to probability or frequency, volume is the sample space, and mass is the embodiment of the final property.

F float = g – f = p liquid GV is discharged in space by a force equal to its influence on the external environment, which is an interaction force

p=f/s, the pressure is the macroscopic quantity of the molecular thermal motion of the group, and the ratio of the vertical force to the two-dimensional plane (vertical vector) is the macroscopic measure of the group.

p=PGH The identity of two different forms of solid and liquid can be determined by the potential energy difference

Pulley block: f=g total/n linear decomposition

The work done in the same direction as w=fs and fl=gh is also a conserved quantity in the ideal state

p=w/t power is also a limit

n = (w useful/w total) * 100% efficiency has its limits

q=cm△t, qamp=mq, the main property and the multi-level coupling of quantity and time is a kind of general amount

i=q/t flow is the macroscopic quantity of a particle

i=u/r short-range of various approximations, in a potential difference to the differential of the hindrance can be analogous to the flow and quantity to the differentiation of time

p=iu ideal model

1/r=1/r1+1/r2 is a coupling, which is the embodiment of the atomic structure

The i1/i2=r1/r2 ratio is also conserved

The property of an object that remains in an unchanging state of motion is called inertia, which is a quantification of mass

Force is not the cause of producing (sustaining) motion, but the cause of change

Under certain conditions, various forms of energy can be converted into each other, and the conversion is bound to be efficient, that is, the probability conversion, so there is a loss

The one-way measurement requires another dimension of comparison, if only the milk density is measured with a balance, then (1) the mass of the empty cup m1 (2) the cup is filled with milk, and the total mass of the measurement m2 (3) the milk is poured out, and the cup is filled with water after drying, and the total mass m3 is measured, and the result expression: p = (m2-m1) p water / (m3-m1) requires both a premise and a conversion ratio

The equilibrium force must be the force that one object is subjected to at the same time, and the interaction force is the force between two objects, which is an important concept and is the transformation path of internalization and externalization

Regularity, insight into inner relationships

A melody-like path completes the network

A partial differential equation is the relationship of a function to multiple variables, which is the structure of a network

Ben Ford's Law, a certain frequency distribution of numbers, 1 is 30%, and so on

The density of the network is the connectivity of nodes, and the relationship between physical mass and inertia can be substituted into the relationship of the network

The motion of the network is a measure of change, and force is a description of f=ma, in accordance with Newton's first-two-third law: the action of force is reciprocal, a state of inertia

The relativity of motion, the standard of measurement is relative proportion, which is a certain proportion of the cycle

Equilibrium is the relative proportion of concentrations, and the concept of pressure is the difference in relative concentrations

Compatibility of different properties, resistance to changes in buoyancy

The resistance changes of the network can form the overall network

The relationship between pressure and flow velocity, which is the coupling of network properties, the flow velocity is large and the pressure is small

Energy is a high-dimensional structure, and forces and distances can be varied by certain mechanical devices such as bars and slopes. There is resistance to this process with resistance

The statistical function of thermal motion is a definite distribution

Facts, experience ~ laws ~ discovery of new facts
