The g-force or gravitational force equivalent is mass-specific force (force per unit mass), expressed in units of standard gravity (symbol g or g0, not to be confused with "g", the symbol for grams ). It is used for sustained accelerations, that cause a perception of weight.
pc ⋅ M⊙−1 ⋅ ( km / s) 2. The gravitational constant G is a key quantity in Newton's law of universal gravitation. The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton 's law of universal gravitation and in Albert Einstein 's theory of general relativity.
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation ). [ 2][ 3] It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given by the norm .
Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) [ 1 ] or, incorrectly, zero gravity . Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero.
The coelacanth is the largest extant lobe-finned fish. The largest living lobe-finned fish is the coelacanth. The average weight of the living West Indian Ocean coelacanth, ( Latimeria chalumnae ), is 80 kg (180 lb), and they can reach up to 2 m (6.6 ft) in length. Specimens can weigh up to 110 kg (240 lb).
The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités ), is the modern form of the metric system and the world's most widely used system of measurement. Coordinated by the International Bureau of Weights and Measures (abbreviated BIPM from French: Bureau international des ...
The kilogram per cubic metre (symbol: kg·m−3, or kg/m3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [ 1]
The dalton or unified atomic mass unit (symbols: Da or u) is a unit of mass defined as 1 12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. [ 1][ 2] It is a non-SI unit accepted for use with SI. The atomic mass constant, denoted mu, is defined identically, giving mu = 1 12 ...
