In physics, the newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton in recognition of his work on classical mechanics. It was first used around 1904, but not until 1948 was it officially adopted by the General Conference on Weights and Measures (CGPM) as the name for the mks unit of force.

In physics, Classical mechanics is one of the two major sub-fields of study in the science of mechanics, which is concerned with the motions of bodies, and the forces that cause them. ...

A newton is defined as the amount of force required to accelerate a mass of one kilogram at a rate of one metre per second squared. Acceleration is the time rate of change of velocity, and at any point on a v_t graph, it is given by the gradient of the tangent to that point In physics, acceleration (symbol: a) is defined as the rate of change (or time derivative) of velocity. ...

Metres per second squared is the SI derived unit of acceleration (scalar) and (vector), defined by distance in metres divided by time in seconds and again divided by time in seconds. ...
The newton is an SI derived unit, comprising kg·m·s−2 in SI base units. SI derived units are part of the SI system of measurement units and are derived from the seven SI base units. ...

Since one definition of weight is the force acting between two objects due to gravity, the newton is also the unit of weight. A mass of one kilogram near the Earth's surface has a weight of approximately 9.81 N, although this figure varies by a few tenths of one per cent over the Earth's surface. Conversely, an object with a mass of 9.81−1 kg (≈ 101.94 g) weighs roughly 1 N. Rather fittingly, given the story about how Newton arrived at his theory of gravity, this is about the mass of a small apple. Gravitation is the tendency of masses to move toward each other. ...
Weight is the force exerted upon an object by virtue of its position in a gravitational field. ...
