User:JiachengGeng/Newton (unit)
What I plan to do for this article is explain what exactly the unit Newton is, how you can get a Newton, where and when the Newton came from, and it's uses.
Base on the peer review, I add two change to the draft, one is add a History heading in article, the other is add an example of gravity on moon.
A Newton (symbol = N) is a type of unit that measures the force needed in order to move an object with the mass of one kilogram (km) so that it accelerates at a speed of one meter per second (m/s)[1]. In terms of symbols, N would equal to 1kg*m/s. This unit got it's name after Sir Issac Newton, the iconic figure that sparked the beginning of the Scientific Revolution in the 17th century[2]. Also memorable for his three laws of motion.

History
[edit]In 1946, the Conférence Générale des Poids et Mesures (CGPM) Resolution 2 standardized the unit of force in the MKS system of units to be the amount needed to accelerate 1 kilogram of mass at the rate of 1 metre per second squared. In 1948, the 9th CGPM Resolution 7 adopted the name newton for this force. The MKS system then became the blueprint for today's SI system of units. The newton thus became the standard unit of force in the Système international d'unités (SI), or International System of Units.
The newton is named after Isaac Newton. As with every SI unit named for a person, its symbol starts with an upper case letter (N), but when written in full it follows the rules for capitalisation of a common noun; i.e., "newton" becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case.
Example
[edit]At average gravity on Earth (conventionally, g = 9.80665 m/s2), a kilogram mass exerts a force of about 9.8 newtons.
- An average-sized apple at 200 g, exerts about 2 newtons of force at Earth's surface, which we measure as the apple's weight on Earth.
- 0.200 kg × 9.80665 m/s2 = 1.961 N.
- An average adult exerts a force of about 608 N on Earth.
- 62 kg × 9.80665 m/s2 = 608 N (where 62 kg is the world average adult mass).
While at an average gravity on Moon (conventionally, gravity on Moon = 1.625 m/s2), a kilogram mass exerts a force of about 1.625 newtons, that means they are only have 16.6% (about 1/6) of their weight on Earth.[1]
- An average-sized apple at 200 g, exerts about 0.325 N on Moon.
- An average adult exerts a force of about 100.75 N on Moon.
