What is a newtons?

Answer 1

Sir Isaac newton's second law gives the concept of force in the formula: F = ma. This is read as, force equals mass times acceleration.

In standard international units (SI units) mass is given in kilograms (kg), acceleration is given in meters per second per second (m/s2), and force is given in newtons (N).

Abbreviated as N, a newton is defined as the force required to accelerate 1 kilogram a meter per second squared; in empty space.

This concept is expressed in equations of the form, N = kg*m/s2.

If this were an actual problem, numerical values would precede the associated units. Such as, 8 N = 4kg * 2m/s2.

A newton is a vector unit that relates both the magnitude and direction in SI. We say the force of gravity is -9.81 m/s2. So the force of 3.6 ounces (~1/9.81 kg) at the Earth's surface is 1N down. We could also say this is -1 N up, they are equivalent.

Centimeters, grams, and seconds (CGS) were replaced by the SI's use of kilograms, meters, and seconds (KMS). The CGS unit of force is a dyne (dyn); 1 N = 100 000 dyn.

Answer 2

A newton is a measure of force. It is derived from kg*m/(s^2), where kg is kilogram, m is meter, and s is second.
