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.
Exanewton
An exanewton (EN) is a unit of force equal to 10^18 newtons.
History/Origin
The exanewton was introduced as part of the International System of Units (SI) prefixes to represent extremely large forces, following the adoption of the SI system and its prefixes in the 20th century.
Current Use
The exanewton is primarily used in theoretical physics and large-scale engineering contexts where extremely large forces are involved, though it is rarely used in practical applications due to its size.
