Work done defined as the scalar product of the two vectors force and displacement.

Explanation:

If a force vecF acts on a body and displaces it through vecr and the angle between the two vectors be theta. The work done by the force is given as,

W = vecF*vecr
implies W = FrCos theta, where F and r are the magnitudes of vecF and vecr respectively.
