What is the product of the force or effort needed to move a load multiplied by the distance it was moved?
In physics, work, is defined as the product of force and the amount of displacement in the direction that force is moving. Mathematically it is:U = F(d)where,U = work done on an objectF = force applied to an objectd = displacement of object through the line that the force actsWork is the product of force and displacement, so it's units are units of force times units of length. Examples could be ft*lb or N*m but the SI unit for the measurement of work is the joule. 1 J is equal to 1 N*m.
