Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
Gram-Force Meter
A gram-force meter (gf·m) is a unit of torque or moment of force, representing the force of one gram-force applied at a distance of one meter from the pivot point.
History/Origin
The gram-force meter originated from the use of the gram-force as a unit of force in the centimeter-gram-second (CGS) system, primarily used in scientific and engineering contexts before the adoption of SI units.
Current Use
Today, the gram-force meter is rarely used; it is mainly of historical interest or in specific niche applications where CGS units are still referenced, but most torque measurements are expressed in SI units such as newton-meters.
