Newton (N)

Definition

The Newton (N) is the SI unit of force. It is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (1 N = 1 kg·m/s²).

History

The Newton is named after Sir Isaac Newton, who formulated the laws of motion in the 17th century. The unit was officially adopted in 1948 at the 9th General Conference on Weights and Measures (CGPM) as part of the metric system.

Uses

The Newton is widely used in physics and engineering to quantify force. It plays a crucial role in mechanics, aerodynamics, and various applications, including vehicle dynamics and structural engineering. The unit is used globally, especially in countries that have adopted the metric system.

Conversions

  • 1 Newton = 0.2248 pounds-force (lbf)
  • 1 Newton = 100,000 dynes
  • 1 Newton = 0.10197 kilograms-force (kgf)

Fun Facts

  • A common misconception is that "weight" and "force" are the same; weight is a force measured in Newtons.
  • The Newton is also used in everyday contexts, such as measuring the force of a pull or push in physics classes.
