Actually, there are four forces; the strong atomic force, the electromagnetic force, the weak atomic force, and gravity.
A newton of force is the unit kilogram multiplied by the unit meters per second. It is the most common measurement of force, and is close to the weight of an apple. :)
Horizontal force in one component of the magnetic force on earth. Horizontal is a direction, and force is any external efforts that causes an object to change.
electromotive force, current, resistance, and power
Most likely, you are referring to the electromagnetic force. It is one of the four known forces in physics along with gravity, the weak force, and the strong force.
what source of power is the most common world wide
The most common form of muscle force production is the concentric contraction force.
Glucose is the most common energy source in cellular respiration.
The most common source of electricity in Manitoba is 120/240 volts. This is the supply source for Manitoba homes.

Chickens are the most common source of human infection.
Division is the usual source.
Electromotive force (emf, ) is a term used to characterize electrical devices, such as voltaic cells, thermoelectric devices, electrical generators and transformers, and even resistors. For a given device, if an electric charge Q passes through that device, and gains an energy W, the net emf for that device is the energy gained per unit charge, or W/Q. This has SI units of volts, or joules per coulomb, and hence can be thought of as a voltage induced by the device in question. Since force has the SI unit of the Newton, "electromagnetic force" is a misnomer, but one that over time has resisted change. In most circuits current is driven by a so-called "source of emf", which usually is a voltaic cell (or battery, which consists of voltaic cells in series and/or in parallel) or the power company. For a voltaic cell the source of emf is the chemical reactions that occur at each of the electrode-electrolyte interfaces, so that a voltaic cell can be thought of as two "surface pumps" of atomic dimension. The reactions at the electrode-electrolyte interfaces provide the "seat" of emf for the voltaic cell. For the power company, the source of emf is electromagnetic induction, which is more extended than an atomic size, but nevertheless is confined to the power generation building, usually many miles from the user. Sources of electromotive force include electric generators (both alternating current and continuous current types), batteries, and thermocouples (in a heat gradient). Electromotive force is often denoted by or ℰ (script capital E). Electromotive force is measured in volts (in the International System of Units equal in amount to a joule per coulomb of electric charge). Electromotive force in electrostatic units is the statvolt (in the centimeter gram second system of units equal in amount to an erg per electrostatic unit of charge).
It's enough in most cases; sometimes it's too much, sometimes it's a bit too little as well.
