force

 [fors]
energy or power; that which originates or arrests motion or other activity.
Forces resulting from a fall are transmitted up to the spine through the long leg bones and pelvis. From McQuillan et al., 2002.
electromotive force the force that, by reason of differences in potential, causes a flow of electricity from one place to another, giving rise to an electric current.
reserve force energy above that required for normal functioning. In the heart it is the power that will take care of the additional circulatory burden imposed by bodily exertion.
shearing f's see shear.
van der Waals f's the relatively weak, short-range forces of attraction existing between atoms and molecules, which results in the attraction of nonpolar organic compounds to each other (hydrophobic bonding).

e·lec·tro·mo·tive force (EMF),

the force (measured in volts) that causes the flow of electricity from one point to another.

electromotive force (EMF)

[-mō′tiv]
the electric potential, or ability of electric energy to perform work. EMF is usually measured in joules per coulomb, or volts. The higher the voltage, the greater the potential of electric energy. Any device, such as a storage battery, that converts some form of energy into electricity is a source of EMF.

The force (measured in volts) that causes the flow of electricity from one point to another.

electromotive force,

n the ability of electrical energy to perform work, measured in volts or joules per coulomb.

e·lec·tro·mo·tive force

(EMF) (ĕ-lek'trō-mō'tiv fōrs)
The force (measured in volts) that causes electricity to flow.

electromotive force

the force that, by reason of differences in potential, causes a flow of electricity from one place to another, giving rise to an electric current.
