Newton (unit)
In physics, a newton (symbol: N) is the unit of measure of force in the International System of Units, named in this way by the contributions from Isaac Newton to physics, especially classical mechanics. It is a unit derived from the International System of Units that is made up of the base units:
N=kg⋅ ⋅ ms2{displaystyle mathrm {,N={frac {kgcdot m}{s^{2}}}}}}
A newton is the amount of force applied during one second to a mass of one kilogram so that it acquires the speed of one meter per second with respect to the collinear speed it had prior to the application of the force. Forces are vectorial in nature and are the basis of the study of dynamics, one of the main branches of mechanics.
In 1946, the VIII General Conference on Weights and Measures (CGPM), resolution 2, standardized the unit of force of the MKS system of units as the force necessary to give an acceleration of 1 m/s² to an object of 1 kg of mass. The IX CGPM, of 1948, adopted the name "newton" in its resolution 7.

This unity of the International System is named after Isaac Newton. In the units of the SI whose name comes from a person's own name, the first letter of the symbol is written with capital (N), while his name always starts with a tiny letter (newton), except in case you start a sentence or a title.Based on The International System of UnitsSection 5.2.
