Physical fundamentals 01
The definition of physics is the natural science branch of the most basic law of the physical world, originating from the natural philosophy of ancient greece. The branch physics of natural philosophy provides a set of principles and laws that explain the various phenomena in nature, such as the newton law of sport, electromagnetic theory, etc. The physics of the interpretation of natural phenomena has contributed to scientific progress through experimental validation of theory and theoretical guidance of experiments. Experiments combined with theory 010203
The structure and interaction of microparticles, such as atoms and molecules, are studied in the basic structural physics of the energy-power-relationship substance of the subject of physics, revealing the nature of the substance. Physics explores the principles of energy conversion and persistence and how power affects the mobility of objects. Electromagnetics of electromagnetic phenomena are important branches of physics, studying charge, current-generated electric fields and magnetic fields and their interactions。
The basic concept of physics is newton's three-state 03-nedon sports law, which explains the basic pattern of physical activity and lays the foundation for classical mechanics. The state of ice, liquid and gas, which sustains law 01 water, demonstrates the basic concept of material state change and is the basis for the introduction of physics. The law of energy persistence states that energy cannot be created or eliminated, but can only be converted from one form to another, one of the core principles of physics. In the 04 quantum mechanics of wave grains, particles such as photons and electrons display both volatility and particle properties, a revolutionary concept in physics。
Mechanical component 02
The basic law of strength and motion is the law of newton, also known as the law of inertia, which states that the object will remain static or evenly motion in a straight line, except by external force. Newton must be newton
