# Work

In everyday life, work means an activity that requires effort.

In science, the term refers specifically to a force acting on an object and the object's displacement.

When an object moves a distance d along a straight line as a result of the action of a force of constant magnitude F in the direction of motion, the work done by the force is

*W = Fd*.This represents the constant-force formula for work.

In the metric system, the unit for work is the newton-meter which is shortened to joule (J).

In the U.S. system, the most common unit of work is foot-pound.

Numerically, work is the area under the force graph.
