Pound Foot/square Second
The pound foot per square second (lb*ft/s^2) is a unit of force representing the force exerted by a one-pound mass accelerated at one foot per second squared.
History/Origin
This unit originated from the imperial system of units, primarily used in the United States, to quantify force based on the pound as a unit of mass and foot as a unit of distance, with seconds as the time unit. It is related to the pound-force (lbf) but includes a distance component, making it a derived unit in mechanics.
Current Use
The pound foot per square second is rarely used in modern practice; force is typically expressed in pound-force (lbf). When used, it appears in specific engineering contexts involving force calculations in imperial units, especially in classical mechanics and engineering analyses.
Femtonewton
A femtonewton (fN) is a unit of force equal to 10^-15 newtons.
History/Origin
The femtonewton is part of the metric system's SI prefixes, introduced to measure extremely small forces, particularly in scientific and engineering contexts involving micro- or nano-scale phenomena.
Current Use
Femtonewtons are used in fields such as nanotechnology, molecular physics, and precision measurements where forces at the femtonewton scale are relevant.
