- The work done by a force, →F, on an object over a displacement, →d, is defined to be: W = →F ⋅ →d = Fdcosθ = Fxdx + Fydy + Fzdz where θ is the angle between the vectors when they are placed tail to tail, as in Figure 7.1.1. The dimension of work, force times displacement, is also called "energy''.
