Pound-Force
Pound-force (lbf) is a unit of force in the imperial system, defined as the force required to accelerate a one-pound mass at a rate of 32.174 feet per second squared.
History/Origin
The pound-force originated from the British Imperial system and has been used historically in engineering and physics to quantify force, especially in the United States and the UK, before the widespread adoption of the SI system.
Current Use
Today, pound-force is primarily used in the United States and some other countries for engineering, manufacturing, and mechanical applications where imperial units are still prevalent, often in contexts like specifying engine torque or structural loads.
Attonewton
An attonewton (aN) is a unit of force equal to 10^-18 newtons.
History/Origin
The attonewton is part of the SI prefixes system, introduced to measure extremely small forces, with its usage becoming more relevant in nanotechnology and precision measurements.
Current Use
Attonewtons are used in scientific research involving microscopic forces, such as in atomic and molecular physics, and in nanotechnology applications where very small forces are measured.
