From Citizendium, the Citizens' Compendium
- Physics : The study of forces and energies in space and time.
- Engineering : The profession in which a knowledge of the mathematical and natural sciences gained by study, experience and practice is applied with judgment to develop ways to economically use the materials and forces of nature for the benefit of mankind.
- Force : Vector quantity that tends to produce an acceleration of a body in the direction of its application.
- Abampere : Unit of electric current in the cgs-emu system of units; symbol abA; 1 abA = 10 A.
- Electric field : force acting on an electric charge—a vector field.
- Erg (unit) : A cgs unit of energy (obsolete); 1 erg = 10−7 joule
- Kilogram-force : A unit of force which will accelerate 1 kilogram of mass to 9.80665 m/s2, the standard average acceleration due to gravity on Earth's surface (referred to as gn).
- Oersted (unit) : Unit of magnetic-field strength |H| in the Gaussian system of units; symbol Oe; 1 Oe = 1000/4π A⋅turn/m.
- Newton : SI derived unit of force, named after Isaac Newton, equal to the amount of force required to accelerate a mass of one kilogram at a rate of one metre per second per second.
- Pound-force : A measurement unit of force which will accelerate 1 pound of mass to 9.80665 m/s2 (≈ 32.17405 ft/s2), the standard average acceleration due to gravity on Earth's surface (referred to as gn).
- Statcoulomb : Unit of electric charge in cgs-esu units: 1 statC = C/(10⋅c), with c the speed of light in m/s.
