Some Fundamental Laws of Physics

Here are some fundamental laws of physics that serve as the foundation for understanding the physical world:

1. Newton's Laws of Motion

First Law (Inertia): A body which is at rest will remain at rest and a body moving will continue to move until inclined in different direction by an external force.
Second Law (F = ma): The force act on an object is equal to the mass times the acceleration of that particular object.
Third Law (Action and Reaction): In this famous newton’s third law usually said that to every action there is always an opposite reaction that is equal in magnitude.

2. Law of Universal Gravitation

Every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

3. Conservation Laws

Conservation of Energy: Energy cannot be created or destroyed though he or she can be converted in one form to the other.
Conservation of Momentum: According to analysis of the system, total momentum of an isolated system does not change if no external force acts on it.
Conservation of Angular Momentum: It is further noted that if no external torque acts in a system, the angular momentum of a system is conserved.

4. Coulomb's Law

It states that force between two charged particles is directly proportional to the product of charges of the particles and is inversely proportional to the square of the distance between charges.

5. Ohm's Law

Now the current passing through a conductor between two points is equal to the voltage across two points and inversely proportion to the resistance. \( V = IR \)

6. Thermodynamics Laws

Zeroth Law: Two system are said to be in thermal equilibrium if they are in thermal equilibrium with a third system.
First Law: There has been noted a relation of the change of the internal energy of the system which has been equal to the heat supplied to the system subtracted by the work done by the system or in other words undergoing (Conservation of Energy).
Second Law: In an isolated system, there is a principle stating that an amount of disorder will increase continually.
Third Law: This is because with increasing the temperature the only system which is possible corresponds to an approach to a minimum value as the temperature approaches absolute zero.

7. Maxwell's Equations

These are four equations that describe how electric and magnetic fields interact:

Gauss's Law for Electricity: Electric flux is defined as the intensity with which the electric lines of force pass through a closed surface and depends upon the charge enclosed by this surface.
Gauss's Law for Magnetism: It is impossible to speak about magnetic charges; the known lines are in the form of loops.
Faraday's Law of Induction: Flux density alters with time and it yields an electric field.
Ampère's Law (with Maxwell's addition): Electric currents generate magnets fields and oscillating electric fields also generate magnetic fields.

8. Einstein’s Theory of relativity

Special Relativity: It has been found that the laws of physics are EQUAL in all Inertial Frames; the SPEED OF LIGHT is SAME for all observers in VACUO.
General Relativity: For instance, gravity is not force but a curvature of space time which results from the presence of mass and energy.

9. Taylor’s Executions-Perrsonal Growth (Management)

There are certain physical properties of any particle that cannot both be known with perfect precision at the same time.

10. Planck's Law

Outlines the characteristics of the electromagnetic radiation that is in thermal equilibrium with a black body. This is a fundamental law in quantum mechanics that over comes the association between energy of photons and the frequency.

11. Pauli Exclusion Principle

Such as in the quantum mechanic, two fermions can never share the same quantum state for instance two electrons. This principle also gives a clear picture of the periodic table as well as the electrons within an atom .

12. Archimedes' Principle

A body is in a fluid; it feels a upward force on it with the magnitude equal to the weight of the fluid that is equivalent to the volume of space occupied by the body. This principle will help explain why a particular object floats on water or perhaps may sink.

13. Snell’s law also known as the Law of Refraction

Their measure is the ratio of sine of angle of incidence to sine of angle of refraction for that media. Frequently it is used to describe how much light may bend in transition from one material to the next.

14. Law of Reflection

The angle at which waves approaching a surface are incident is equal to the angle of the reflected waves, when they reflect off the surface.

15. Hooke's Law

The amount of force required to stretch or contract a spring by some extent is directly proportionate to the extent. \( F = kx \), where participate spring constant \( k \) and displacements from equilibrium condition \( x \).

16. Bernoulli's Principle

In fluid dynamics, pressure or potential energy of a fluid decreases with an increase in speed of the fluid.Fig.1 is a representation of a cross-section of a fluid element and approximates to a control volume. This principle is responsible for understanding of the mechanisms of an airplane’s lift and various actions of fluids in pipelines.

17. Hubble's Law

The degree of redshift in the spectrum of light of a galaxy is directly proportional to the distance of the same galaxy from the observer. This law bears credit to the theory that the universe is still expanding.

18. Boyle’s Law (Gas Laws)

The pressure of any given mass of gas is directly proportional to the temperature; inversely proportional to voluem. According to the exact behavioral assumption \( P \times V = \text{constant} \).

19. Charles’s Law

Volume of a gas at a given pressure has direct relation with temperature. \( V \propto T \).

20. Stefan-Boltzmann Law

There is the conclusion that the total of radiant heat, emitted from the surface of a black body, increases in direct proportion to the fourth power of the absolute temperature. \( P = \sigma T^4 \) For \( \sigma \), one has Stefan- Boltzmann constant.

21. Three laws as formulated by Kepler are known as Kepler’s laws of planetary motion.

First Law (Law of Ellipses): A planet’s orbit is an ellipse with the Sun at one of the ellipse’s focal points.
Second Law (Law of Equal Areas): A straight line connecting a planet and the Sun moves such way that it covers equal areas in equal amounts of time.
Third Law (Law of Harmonies): The ratio of the square of the orbital period of a particular planet is directly proportional with the cube of the semi-major axis of the orbit.

22. Lenz's Law

The current induced in a conductor by a varying magnetic field is so arranged to generate an opposing magnetic field. From the laws of energy conservation the above law can be understood.

23. Fick's Laws of Diffusion

Explains the manner in which particle move from a concentrated area to a lesser concentrated area. The first is given as: Diffusion flux ∝ Concentration gradient

24. Wave Theory /Law of superposition

They overlap and the resultant wave is obtained by adding more waves together at the frequency of the occurrences. It works for sound waves, light waves and for any secondary wave that you can think of.

26. The concept is named Fermat’s Principle of Least Time.

It is known that light selects the way which will be the shortest time between two points. It is used to obtain Snell’s law of refraction as one of this principles.

27. de Broglie Hypothesis

Quantum mechanics to a certain extent particles have wave like behaviour and the wavelengths of a particle are inversely proportional to its momentum.

28. Wien's Displacement Law

The black body radiation curve for different temperatures has always its maximum at the wavelength varying inversely with the temperature. It helps to find out how hot stars and all other objects red or of any other color are.

30. Noether’s Theorem

This rather deep statement in theoretical physics is pinpointing at the fact that each differentiated symmetry of the action of a physical system has a point with a conservation law. For instance, time invariance is position energy, and the rotational invariance is the conservation of angular momentum.

These laws as well as principles serve as the foundations of current physic and physics applying to classical and quantum mechanics, as well as to atom and molecule behaviors and celestial object movements.
