1 City (1990 pop. 16,700), seat of Harvey co., S central Kans., in an agricultural area; inc. 1872. It is a railroad division point with railroad shops and has a large mobile home industry in addition to oil wells. Machinery, motor vehicle parts, plastic products, glass, and furniture are also produced, and there is flour milling. The Chisholm TrailChisholm Trail,
route over which vast herds of cattle were driven from Texas to the railheads in Kansas after the Civil War. Its name is generally believed to come from Jesse Chisholm, a part-Cherokee trader who, in the spring of 1866, drove his wagon, heavily loaded with

; it is the force that produces an acceleration of 1 meter per second per second when exerted on a mass of 1 kilogram. The newton is named for Sir Isaac Newton.


(new -tŏn) Symbol: N. The SI unit of force, equal to the force that gives a mass of one kilogram an acceleration of one meter per second per second.



a city in the northeastern United States, in the state of Massachusetts. Population, 91,000 (1970). Newton is a residential and industrial suburb to the west of Boston. A total of 13,000 workers are employed in industry there. Leading industries include radioelectronics, instrument-making, light industry, and general machine-building.



the unit of force in the International System of Units. It is named after I. Newton, and the international symbol is N. The newton is equal to the force that imparts to a body with a mass of 1 kg an acceleration of 1 m/sec2 in the direction of the force. With the adoption of the International System, the newton will replace other units of force, such as the kilogram-force (1 kgf = 9.80665 N), the ton-force (1 ton-force = 9806.65 N), the dyne (1 dyne = 10−5 N), and the British pound-force (1 lbf = 4.45 N).


The unit of force in the meter-kilogram-second system, equal to the force which will impart an acceleration of 1 meter per second squared to the International Prototype Kilogram mass. Symbolized N. Formerly known as large dyne.

newton (N)

The unit of force in the International System of Units; the force necessary to produce an acceleration of 1 metre per second-square in a body having a mass of 1 kilogram.


the derived SI unit of force that imparts an acceleration of 1 metre per second per second to a mass of 1 kilogram; equivalent to 105 dynes or 7.233 poundals.


Sir Isaac. 1642--1727, English mathematician, physicist, astronomer, and philosopher, noted particularly for his law of gravitation, his three laws of motion, his theory that light is composed of corpuscles, and his development of calculus independently of Leibnitz. His works include Principia Mathematica (1687) and Opticks (1704)

(1) (newton) A unit of force in the MKS system. It is the force required to accelerate one kilogram by one meter per second squared.

(2) A set of mobile computing technologies from Apple introduced in 1993 with its MessagePad personal digital assistant (PDA). The ARM-based MessagePad included handwriting recognition, an infrared port for local data transfer and a fax/modem for e-mail and faxes. Although the MessagePad was the name of the device, it was commonly called the "Newton." The handwriting technology was often criticized for not being up to par; however, proponents of the device claimed it worked well if the user had the patience to train it properly.

The Newton eMate
In 1997, Apple offered the educational market a Newton-derived portable computer called the "eMate 300." Also using an ARM processor, the eMate had a full-size keyboard that was housed in a case similar in design to the iBook laptop, which was introduced two years later.

A Five-Year Reign
In 1998, Apple stopped production of Newton products due to competition from Palm PDAs, which were becoming popular. Apple folded the Newton, Inc. subsidiary back into the company after having spun it off a year earlier to specialize in the PDA niche. Some of the components of the Newton handwriting technology made their way into the Mac OS X operating system a few years later. See PDA and ARM chips.

Apple's MessagePad
More commonly known as the "Newton," which is the technology behind the MessagePad, this handheld unit pioneered the PDA. (Image courtesy of Apple Inc.)
