Poundal

pdl

Definition

The poundal is a unit of force in the foot-pound-second (FPS) system of units. It is defined as the force required to accelerate a mass of one pound at a rate of one foot per second squared. The poundal is equal to approximately 0.138 Newtons.

History/Origin

The poundal was introduced as part of the FPS (foot-pound-second) system of units in the 19th century. It was widely used in physics and engineering before the adoption of the MKS (meter-kilogram-second) system. The name comes from the combination of "pound" and "acceleration".

Current Use

Still used in some areas of physics and engineering, particularly in the United States. Common in some engineering applications where the FPS system is still used. Used in some scientific instruments and laboratory equipment that were designed using the FPS system.

Newton

N

Definition

The Newton is the SI unit of force, named after Sir Isaac Newton. It is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. The Newton is fundamental in physics and engineering, representing the basic unit of force in the International System of Units.

History/Origin

Named after Sir Isaac Newton (1643-1727), the Newton was officially adopted as the SI unit of force in 1948. Newton's second law of motion (F = ma) forms the foundation for this unit's definition. The unit was established to honor Newton's contributions to classical mechanics and his formulation of the laws of motion.

Current Use

Widely used in physics, engineering, and scientific applications. Essential for measuring forces in mechanical systems, structural engineering, and physics experiments. Common in automotive industry for measuring engine power, in construction for structural loads, and in physics education for force calculations.
