Work

When a constant force $F$ acts for a distance $s$ in the direction of the force, the work done $W$ is the product of the force and the distanceMATH

Work results from a force acting upon an object to cause a displacement. There are three key words in this definition--- force, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.

If the force is applied at an angle to the displacement, only the component of the force that acts in the direction of the displacement is relevant for the formula above.
