Le Chateliers principle

Predicts effect of change in conditions on chemical equilibria

Marconis law

Relation between length of antenna and maximum signalling distance for radio transmissions

Moore law

Transistors in computers double every 2 years

Occams razor

Oversimplification - simplest answer is probably the right one

Ohms law

Current through a conducter is proportional to voltage across 2 points

Pascal's law

Fluid mechanics | Pressure change in incompressible fluid is transmitted through the fluid so the same change occurs everywhere

Plancks law

Spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium

Poisson distribution

Probability of a given number of event happening in discrete time or space

Price theorem

Natural selection | How trait or allele changes in frequency over time

Ptolemy field

Geometry

Raman scattering

Scattering of photons by matter

Snells law

Optics | Relationship between angles of incidence and refraction

What is Young modulus

Tensile stress over tensile strain

Newton's first law

Velocity will not change unless net force acts on it

Newton's second law

Force is proportional to rate of change in momentum | Force = mass x acceleration

Newton's 3rd law

Every force has equal, opposite reaction

What is unit of charge

Coulomb Smallest unit of charge is electron

Unit of current

Ampere

What is unit of potential difference, ie work done per unit charge moved

Volt

What is unit of work done

Joules In everyday use, kilowatt-hour In studying photons, electronvolt

What is charge carrier in a) solids, b) liquids

Solids - electrons Liquids - ions Substance containing ions that conduct electricity = electrolyte

What is unit of resistance

Ohms

What is unit of power (rate of transfer of electricity)

Watts

What did Max Planck discover

Electromagnetic waves can only be released in discrete packets, called quanta. E.g. photons (suggested by einstein)

What does De Broglie equation relate to

Relates how the properties of waves and particles relate

What is pressure law

At constant volume, pressure of gas is proportional to temp

Keplers laws developed when and in relation to what

1600, motion of planets around sun

What is coulombs law

Finds force of attraction between 2 point charges

Flemings left hand rule

Interaction of conductor perpendicular to a magnetic field

What is Lenz's law to do with
