Ampere's Law

Ampere's Law states that, for constant current flow, the flux of electrical current through a surface is proportional to the line integral of the magnetic field (counterclockwise) around its boundary

Archimedes' principle

Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics

Avogadro's Hypothesis

Avogadro's hypothesis states that at the same temperature and pressure, the same volume of any gas will contain the same number of molecules.

Boyle's lawBoyle's law

Boyle's law states that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.

Brownian motion

Brownian motion is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the quick atoms or molecules in the gas or liquid.

Charles's law

Charles's law states If the pressure of a gas remains constant, the volume of the gas will increase as the temperature increases.

Compton effect

Compton effect is a phenomenon in which a collision between a photon and a particle results in an increase in the kinetic energy of the particle and a corresponding increase in the wavelength of the photon

Conservation of energy

The law of conservation of energy stated that energy cannot be created or destroy but it can be transformed from one form to another. This implies that when energy is converted from one form to another, no energy is lost or created during the conversion process.

Coulomb's Law

The interaction between charged objects is a non-contact force that acts over some distance of separation.

Curie's law

In a paramagnetic material the magnetization of the material is (approximately) directly proportional to an applied magnetic field. However, if the material is heated, this proportionality is reduced: for a fixed value of the field, the magnetization is (approximately) inversely proportional to temperature

Dalton's law of partial pressures

Dalton's law (also called Dalton's law of partial pressures) states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.

Faraday's Law

Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil. No matter how the change is produced, the voltage will be generated. The change could be produced by changing the magnetic field strength, moving a magnet toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil relative to the magnet, etc.

Faraday's First Law Of Electrolysis

The mass of the substance librated or deposited on an electrode during electrolysis is directly proportional to the quantity of electric charge passed through the electrolyte.

Faraday's Second Law Of Electrolysis

If the same quantity of electricity (electric charge) is passed through different electrolytes, the mass of an substance librated or deposited altered at an electrode is directly proportional to their chemical equivalents.

Gauss's law of Electricity

The net number of electric field lines passing through a Gaussian surface is proportional to the total charge enclosed by the Gaussian surface.

Gauss's Law of Magnetism

The net number of magnetic field lines passing through a Gaussian surface is always zero.

Hooke's law

Hooke's law is a principle of physics that states that the force F needed to extend or compress a spring by some distance X is proportional to that distance.

Ideal Gas Law

An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces.

Joule's first law

Joule's first law (Joule heating), a physical law expressing the relationship between the heat generated and current flowing through a conductor.

Joule's second law

Joule's second law states that the internal energy of an ideal gas is independent of its volume and pressure, depending only on its temperature.

Lenz's law

Lenz's law is a common way of understanding how electromagnetic circuits obey Newton's third law and the conservation of energy.

Newton's first laws of motion

The first law states that a body remains at rest or in uniform motion in a straight line unless acted upon by a force.

Newton's second laws of motion

The second law states that a body's rate of change of momentum is proportional to the force causing it.

Newton's third laws of motion

The third law states that when a force acts on a body due to another body, then an equal and opposite force acts simultaneously on that body

Ohm's law

Ohm's law emphasis the principle that the electric current passing through a conductor is directly proportional to the potential difference across it, provided that the temperature remains constant. The constant of proportionality is the resistance of the conductor

Pascal’s principle

Pascal’s principle states that in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container.

Laws of reflection

The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal. The reflected ray and the incident ray are on the opposite sides of the normal.(wikipedia)

Law of Refraction

Law of Refraction stated that When light travels from one medium to another, it generally bends.

Snell's Law

Snell's Law relates the indices of refraction n of the two media to the directions of propagation in terms of the angles to the normal.

Uncertainty principle

Uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle known as complementary variables, such as position x and momentum p, can be known simultaneously (wikipedia)

Van der Waals force

Van der Waals force stated that the sum of the attractive or repulsive forces between molecules (or between parts of the same molecule) other than those due to covalent bonds, the hydrogen bonds, or the electrostatic interaction of ions with one another or with neutral molecules or charged molecules

First law of thermodynamics

The first law establishes a notion of internal energy for a thermodynamic system. Heat and work are forms of energy transfer. The internal energy of a thermodynamic system may change as heat or matter is transferred into or out of the system or work is done on or by the system

Second law of thermodynamics

An isolated physical system, if not already in its own internal state of thermodynamic equilibrium, spontaneously evolves towards it. In an isolated physical system, there is a tendency towards spatial homogeneity.

Third law of thermodynamics

There are various ways of expressing the third law. They derive from the statistical mechanical explanation of thermodynamics. They refer to ideally perfect theoretical models of physical systems.
