# Newton (unit)

*27 December 2010*.

The **newton** is the SI unit of force, and is the force which will accelerate one kilogram one metre per second squared. The symbol of the newton in SI is **N**. The newton is also the unit of weight (force acting on a mass by gravitation).

The newton is named for Isaac Newton (1642 - 1727), who developed the laws of motion in classical mechanics.

The newton is a derived unit in the SI:

- .

## [edit] Related units

- The pascal (Pa) is the SI unit of pressure, and is equal to one newton acting over an area of one square metre.

- The newton-metre (N·m) is the SI unit of torque, and is the amount of torque generated by a force of one newton acting at a radius of one metre. There is no distinct name for this unit.

## [edit] Practical use

A kilogram mass has a weight of about 9.81 N, because *g* (acceleration due to gravity) is on earth 9.81 m/s^{2}).
A healthy adult human subject to earth's surface gravity typically weighs between 450 N and 900 N.
(taking *g* approximately equal to 10 m/s^{2}: the typical mass of an adult is between 45 kg and 90 kg).

The drive train of a 2006 Chevrolet Corvette Z06 can produce approximately 10.3 kN while accelerating the car from 0 to 26.8 m/s (60 miles per hour).
