Work is said to be done when the force applied on an object produces a displacement of the object in the direction of force applied.
Work = Force x displacement (expression for positive work)
Work done is said to be positive if displacement of the object is along the direction of force applied. S.I unit of work done = Joule.

Answer:
work is said to be done if a force acting on a body displaced the body from the position along the direction of the force
SI unit is joule
