Force is defined by Newton's Second Law, which states that the net force on a particle is equal to the time rate of change of its momentum. The units for momentum are mass x velocity. Hence the units of force are mass x velocity / time.

The newton is the SI unit of force, and is equivalent to 1 kg x m / s^2

The Dyne is the CGS unit of force, and is equivalent to 1 g x cm /s^2

The pound is the EEU unit of force, and is equivalent to 1 lb x ft / s^2
