A unit of force is a measure of the amount of energy required to move an object. The most commonly used unit of force is the Newton, which is abbreviated as N and is equal to the amount of force required to accelerate one kilogram of mass at one meter per second squared. Another unit of force is the GEE, which is abbreviated as G and is equal to the amount of force required to accelerate one kilogram of mass at one meter per second squared. The Volt is another unit of force, abbreviated as V, and is equal to the amount of force required to accelerate one kilogram of mass at one meter per second squared. The Dyne is also a unit of force, abbreviated as D, and is equal to the amount of force required to accelerate one gram of mass at one centimeter per second squared. The ERG is another unit of force, abbreviated as E, and is equal to the amount of force required to accelerate one gram of mass at one centimeter per second squared. Finally, the COP is a unit of force, abbreviated as C, and is equal to the amount of force required to accelerate one kilogram of mass at one meter per second squared.
