Planck length — noun A unit of length, believed to be the smallest length that has physical meaning, that is defined in terms of the speed of light, the gravitational constant and the reduced Plancks constant viz … Wiktionary
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
Length scale — In physics, length scale is a particular length or distance determined with the precision of one order (or a few orders) of magnitude. The concept of length scale is particularly important because physical phenomena of different length scales… … Wikipedia
Planck current — The Planck current is the unit of electric current, denoted by Ip, in the system of natural units known as Planck units. I p = q p/t p = (c^6 4 pi varepsilon 0 / G )^ frac{1}{2} ≈ 3.479 times; 1025 Awhere:q p = (c hbar 4 pi varepsilon 0 )^… … Wikipedia
Planck time — In physics, the Planck time ( tP ), is the unit of time in the system of natural units known as Planck units. It is the time it would take a photon travelling at the speed of light in a vacuum to cross a distance equal to the Planck length.cite… … Wikipedia
Planck energy — In physics, the unit of energy in the system of natural units known as Planck units is called the Planck energy, denoted by E P.:E p = sqrt{frac{hbar c^5}{G approx 1.956 times; 109 J approx 1.22 times; 1019 GeV approx 0.5433 MWhwhere c is the… … Wikipedia
