Force
Force is a term used to describe a quantity that acts on an object to change object's state or to perform a task on the object. Example Force used to push or pull a cart or force used to break a stick

Force's Pressure
Force exerts on a cross sectional area of a surface of an object is called Pressure
 * $$P = \frac{F}{A}$$

Work Done
The ability of a Force to carry out a task on an object is defined Work done on the object. Work done by a force on an object to move object over a distance s is defined as the product of Force and Distance move
 * $$W = F s = F v t = p v$$
 * $$W = F \int v(t) dt$$

Energy
The ability of a Force to carry out a task on an object over a period of Time.
 * $$E = \frac{W}{t} = F \frac{s}{t} = F v = F a t = p a$$


 * $$E = \frac{F}{t} \int v(t) dt$$

Motion Force
Motion Force is a force used to set an object in motion. Force to make an object move is calculated by
 * $$F = m a $$
 * $$F = m \frac{v}{t} = \frac{p}{t}$$

For any motion of speed v(t) caused by a force
 * $$F = m \frac{dv(t)}{dt}$$

Gravitational Force
Attraction's Force of the Earth to attract any object toward the Earth
 * $$g = G \frac{m}{r^2}$$
 * $$F_g = M g = G \frac{m M}{r^2}$$

ElectroMotive Force
ElectroMotive Force is the electric force that set stationary charge to move in a straight horizontal line
 * $$F_E = q E$$

ElectroMagnetoMotive Force
ElectroMagnetoMotive Force is the magnetic force that set the moving charge to move in perpendicular to the horizontal direction
 * $$F_B = \pm vB$$

ElectroMagnetic Force
ElectroMagnetic Force is the sum of the Electric Field Force and the Electric force
 * $$F_EB = F_E + F_B = q(E \pm vB)$$

Summary
Force is used to to describe a quantity that acts on matter to perform a task 
 * 1) To cause an object to move or to set an object in motion . Example to push or pull a door
 * 2) To cause matter to change its state . Example change Solid to Liquid to Gas
