Planck units — are units of measurement named after the German physicist Max Planck, who first proposed them in 1899. They are an example of natural units, i.e. units of measurement designed so that certain fundamental physical constants are normalized to 1. In … Wikipedia
Planck force — is the derived unit of force resulting from the definition of the base Planck units for time, length, and mass. It is equal to the natural unit of momentum divided by the natural unit of time.:F P = frac{m P c}{t P} = frac{c^4}{G} = 1.21027 imes… … Wikipedia
Planck momentum — is the unit of momentum, denoted by m P c, in the system of natural units known as Planck units.m P c = frac{hbar}{l P} = sqrt{frac{hbar c^3}{G approx 6.52485 kg m/swhere*{l P} is the Planck length *hbar is the reduced Planck s constant *c is the … Wikipedia

Planck scale — In particle physics and physical cosmology, the Planck scale is an energy scale around 1.22 × 1028 eV (which corresponds by the mass–energy equivalence to the Planck mass 2.17645 × 10−8 kg) at which quantum effects of gravity become strong. At… … Wikipedia
Planck particle — A Planck particle is a hypothetical subatomic particle, defined as a tiny black hole whose Compton wavelength is the same as its Schwarzschild radius. Its mass is thus (by definition) equal to the Planck mass, and its Compton wavelength and… … Wikipedia
Planck density — The Planck density is the unit of density, denoted by ρP, in the system of natural units known as Planck units.: ho P = frac{m P}{l P^3} = frac{c^5}{hbar G^2} ≈ 5.1 times; 1096 kg/m3where:: mP is the Planck mass: lP is the Planck length: c is the … Wikipedia
Planck (disambiguation) — Max Planck was one of the most important German physicists of the late 19th and early 20th century, and is considered to be the founder of quantum theory.Planck may also refer to: * Planck s law of black body radiation * Planck s constant *… … Wikipedia
Planck temperature — The Planck temperature, named after German physicist Max Planck, is the unit of temperature, denoted by TP, in the system of natural units known as Planck units. It is one of the Planck units that represent a fundamental limit of quantum… … Wikipedia
