Extended Information: I. Overview of the Laws of Physics:

The laws of physics are theoretical disciplines derived from special facts. The laws of physics are typical conclusions based on repeated experiments and observations over many years and generally accepted in the scientific field. It is the basic purpose of science to describe our environment in the form of laws.

Not all authors use the laws of physics the same.

2. The nature of the laws of physics.

1. The laws of physics have the following properties:

2. Universal, it is applicable everywhere in the universe.

3. Absolutely, nothing in the universe can affect it.

4. There is generally a conservation relationship of quantity.

Many of the laws of physics are actually isomorphic laws that apply the same formula. I recommend to the students the new best-selling book "A Brief History of Laws" published by Unity Publishing House in August 2022, which classifies all the laws, divides the genealogy, follows the ideas of scientists, and tells the story of scientists discovering each law with smooth and humorous writing, so that you can grasp the essence of physics, chemistry, mathematics, and biology in a relaxed and enjoyable way, making learning easier and more interesting. [Agree] [Agree].

The famous 17 theorems of physics are:

Junior high school physics has Newton's first law, the law of reflection of light, the law of refraction of light, the law of conservation of energy, the law of electric current, Ohm's law and other laws, the specific analysis is as follows:

Newton's first law, also known as the law of inertia, states that all objects always remain at rest or in a uniform linear motion when they are not affected by external forces; The law of reflection of light: one side, two sides, three equal sizes.

The angle between the incident ray and the normal is the angle of incidence. The angle between the reflected ray and the normal is the reflection angle; The law of refraction of light: one side, two sides, three with the big and four empty;

The law of conservation of energy: energy is neither created nor disappeared out of thin air, it only transforms from one form to another, or from one object to another, while the total amount of energy remains the same; Current law: quantity q, voltage u, resistance r; The formula for Ohm's law:

i=u/r，u=ir，r=u/i；

Therefore, it can be seen that junior high school physics has Newton's first law, the law of reflection of light, the law of refraction of light, the law of conservation of energy, the law of electric current, Ohm's law and other laws.

The laws of physics derived from the principle of symmetry

Many fundamental laws of physics are the result of various symmetry mathematics of time, space, or other properties of nature. In particular, some of Newton's conservation laws are related to some symmetry; For example, the conservation of energy is the result of the symmetry of the movement of time (the same at any moment in time), while the conservation of momentum is the result of the symmetry (uniformity) of space (there is no special point in space).

The indistinguishability of all particles of various elementary types (e.g., electrons, or photons) leads to Dirac and Bose quantum statistics, which leads to the Pauli incompatibility principle of fermions. The rotational symmetry of the coordinate axes between time and space (taking one as the imaginary axis and the other as the real axis) leads to the Lorentz transformation. And then the special theory of relativity is derived.

The symmetry between the inertial mass and the gravitational mass derives the general theory of relativity.

The three laws of physics refer to the three fundamental laws in classical physics, known as Newton's three laws, which are:

1.Newton's first law (law of inertia): If no external force acts on an object, or if the net force is zero, the object will remain at rest or in a uniform linear motion. In other words, the object will remain in its state of motion until it is changed by the action of an external force.

2.Newton's second law (law of motion): When an external force acts on an object, the acceleration of the object is directly proportional to the magnitude of the external force and inversely proportional to the mass of the object.

i.e. $f=ma$, where $f$ represents the resultant force experienced by the object, $m$ represents the mass of the object, and $a$ represents the acceleration of the object.

3.Newton's third law (Law of Action and Reaction): If one object exerts a force on another object, then the second object will react to the first object with the same magnitude and opposite force.

In other words, for any force to act, there is a reaction force of equal magnitude and direction.

These laws provide the basic framework for classical mechanics, describing the basic laws of motion and interaction of objects. They are widely used to study celestial motion, mechanical systems, mechanical engineering, and other fields. It is important to note that these laws apply to objects at low and medium velocities and macroscopic scales, and for high-speed motion and microscopic particle behavior, more refined theories such as relativity and quantum mechanics are required.
