What is the term work?

Work (scalar quantity in physics)

"The transfer of energy from one physical system to another, especially the transfer of energy to a body by the application of a force that moves the body in the direction of the force. It is calculated as the product of the force and the distance through which the body moves and is expressed in joules, ergs, and foot-pounds."

The formulas for computing work are W = f * d or W = P * t

Work = Force applied * distance travelled. Work = Power * Time applied

The SI unit is the joule (kg-m2 /sec2 ), equivalent to 1 x 107 ergs.
