[Etymology: I. Newton; England 1642-1727] force. Symbol N. SI, Metric-m.k.s. Identically kg·m·s-2, i.e. the force that gives to a mass of 1 kilogram an acceleration of 1 metre per second, per second (= m·kg·s-2 in base terms). The following are among the coherent derived units:

N·m for moment of force;
N·m = joule for energy, work, quantity of heat;
N·m·s-1 = watt for power, radiant flux;
N·s·m-2 for dynamic viscosity;
N·m-1 for surface tension;
N·m-2 = pascal for pressure.

The name was advocated in 1935
[Hartshorn L., Vigoureux P. Nature Vol. 136, 397 (1935)] and soon became accepted generally.

1946CIPM ‘Unit of force. - The unit of force [in the MKS (Metre, Kilogram, Second) system] is the force which gives to a mass of 1 kilogram an acceleration of 1 metre per second, per second.’see note below

[Le Système International d'Unités (Sèvres, France: Bureau International de Poids et Mesures, 1985)]


Absolute unit of force, abbreviated N, in the metre-kilogram-second (MKS) system of physical units (see International System of Units). It is defined as the force necessary to provide a mass of 1 kg with an acceleration of 1 m per second per second. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 lb in the foot-pound-second (English or U.S.) system. It is named for Isaac Newton, whose second law of motion describes the changes a force can produce in the motion of a body.

N

The SI unit of force. One newton is equal to the force required to give a mass of 1 kg an acceleration of 1 ms−2. One newton force is equal to 0.225 lb force, or 1 lb equals 4.48 N.

 
newton, abbr. N, unit of force in the mks system of units, which is based on the metric system; it is the force that produces an acceleration of 1 meter per second per second when exerted on a mass of 1 kilogram. The newton is named for Sir Isaac Newton.


The SI unit of force; the force that, when acting continuously upon a mass of 1 kilogram, will impart to it an acceleration of 1 meter per second squared. Symbol N.
