Newton
Encyclopedia : N : NE : NEW : Newton
The newton (symbol: N) is the SI unit of force. It is named after Sir Isaac Newton in recognition of his work on classical mechanics.
Definition
A newton is the amount of force required to accelerate a mass of one kilogram by one meter per second squared. For example, 1N is the force of Earth's gravity on an apple with a mass of about 102g.- [1\, \mathrm=1\, \mathrm \cdot \mathrm \cdot \mathrm^]

| This SI unit is named after Isaac Newton. As for all SI units whose names are derived from the proper name of a person, the first letter of its symbol is uppercase (N). But when an SI unit is spelled out, it should always be written in lowercase (newton), unless it begins a sentence or is the name "degree Celsius". — Based on [The International System of Units], section 5.2.
