Symbol Meaning SI unit of measure magnetic vector potential: tesla meter (T⋅m) area: square meter (m 2) amplitude: meter: atomic mass number: unitless acceleration: meter per second squared (m/s 2) magnetic flux density
a symbol for psychology; the wave function in the Schrödinger equation of quantum mechanics; represents: the J/psi mesons in particle physics; the stream function in fluid dynamics; the reciprocal Fibonacci constant; the second Chebyshev function in number theory; the polygamma function in mathematics; the supergolden ratio [8]
together with a degree symbol (°), the Celsius measurement of temperature = °C [10] the circumference of a circle or other closed curve; with a subscript, a cycle on that many vertices; with a subscript, a cyclic group of that order; the complement of a set (lowercase c and the symbol ∁ are also used) an arbitrary category; the number ...
It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ. When a variable with an exponent or in a function is covered, the corresponding inverse is applied to the remainder, i.e. = and = .
basic physics formula triangles: Image title: Image mnemonics in the style of the Ohm's law formula triangle for high-school physics by CMG Lee. Covering the unknown in each mnemonic gives the formula in terms of the remaining parameters. In the SVG file, hover over a symbol for its meaning and formula. Width: 100%: Height: 100%
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion. [ 1 ] In classical mechanics , the kinetic energy of a non-rotating object of mass m traveling at a speed v is 1 2 m v 2 {\textstyle {\frac {1}{2}}mv^{2}} .
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Its symbol is Δ f G˚. All elements in their standard states (diatomic oxygen gas, graphite, etc.) have standard Gibbs free energy change of formation equal to zero, as there is no change involved. Δ f G = Δ f G˚ + RT ln Q f, where Q f is the reaction quotient. At equilibrium, Δ f G = 0, and Q f = K, so the equation becomes Δ f G˚ = − ...
